For anyone who wants a keychain of one of these switches; go to Okeg's topic at deskthority.ne... :) .
A review of my Tesla 259 keyboard often nicknamed "Gerkonic" because of a Russian abbreviation of magnetic reed switches. Hope you enjoy the video! :)
The practice sentence was: "asdflkja hsdfk jlhadfgl;khnrio ujvzln waero;ihjvc, mndfl;hjasd fljhasdflkj ahsdflkjhasdf asdf asdlkfjh kjhaesiruhkj blkzjxjhblk ajbsiouahsd fi uhljnal;sdvu ahersa sere zx,h jk;kl."
I hate to disappoint but the 74 on those chips appears to be referring to the 7400 series of digital logic integrated circuits. In other words, it is not a date. The 7400 series of TTL chips were first produced by Texas Instruments (TI) but other manufacturers adopted the 7400 naming scheme to indicate compatibility with the original chips.
Came here to mention 74-series TTL logic.
Me too, but some git beat me to it! :)
keeping the tradition alive here
I thought the TTL logic chips were part of the 74LS series.
@@iProgramInCpp 74LS denotes a later *L*ow-power *S*chottky technology variant of the original devices. Better technology, but backward compatible with the origional 74 series.
I wish I had a red ФСБ button on my keyboard.
+scolic03 Yeah that's definitely one of the more awesome buttons on the board xD .
lmao
It's ES Series mainframe terminal keyboard, type ЕС-7927-01 (note ЕС in Cyrillic here, just copypaste it in Google for a little bit more images). The model looks like Consul EC0101-1-01. I've no idea about specific year of this particular thing, but that type of keyboard in general was in production up to late 1980s. So it's probably not so old as you suppose.
Note also, the keyboard have different from Qwerty layout for Latin script. The layout is phonetic, i.e. each Latin letter is coupled to Cyrillic letter similar by pronunciation. It's a hint that this keyboard was made in Czechoslovakia especially for export to USSR or Bulgaria.
The funny key with ФСБ on it may mean Фиксация Строчных Букв, i.e. fixed lower case, an opposite function to caps lock on modern keyboards.
It would have been cool if you had the Federal Security Service (formerly KGB) on speed dial.
For the record, Consul was a Czechoslovak series of typewriters. I've only ever seen small mechanical typewriters, probably because that's what was sold to civilians. The electric successor appears to be the Consulta, but that looks more like a IBM Wheelwriter clone than this.
Both Czechs and Slovaks have used latin since the 10th century AD. The azbuka letters are there for export, I believe.
Correct. My mother grew up in Slovakia, so I know that both Czech and Slovak have definitely always been written in Latin letters. During the time of Soviet control, all children in Czechoslovakia had to learn Russian in school as a second language, but this keyboard was most likely made for export to the USSR.
The chips appear to be your standard 74XX series logic chips. They are still used up to this day. The 74 does not indicate the year of manufacture.
^ This
Zbrojovka Brno was a major Czechoslovakian small arms factory at the time. Know for example for the BREN gun. You are holding piece of fine weaponry.
Also Tesla was major Czechoslovakian electronics manufacturer. I don't know why it uses Russian font tho. Maybe it was imported to SSSR or it was used by someone from the Red Army that was occupying Czechoslovakia since 1968.
Got an answer for that question, found out due managing to get a hold of a few.
They were used in various Soviet military installations where they required high reliability hardware, in fact all of the ones I got a hold of were from old Russian (Soviet) military installations. So they were more than likely built to Red Army specifications.
AWESOME! Maybe I should print out a few red star badges or something xD .
That would be both awesome and horribly tacky.
I snagged one that seems similar on ebay, and importantly it has its case intact. Incidentally one more has popped up also. Seems to be called a "Zbrojovka Brno 262.3 Bezkont Klávesnice" (contactless keyboard), so judging by the number it's a later model.
The switches are also of a seemingly different design, and confusingly various sources seems to refer to it as both reed and hall-effect. Images of the PCB do seem unmistakable but still will have to take a closer look when it gets here.
What I intend is to get (at least) one working and talking to a modern pc.
I hate to think what happens to comrade who press key labeled ФСБ...
I love the "ФСБ" key. Would be useful if you want to report something to the Federal Security Service. :)
+TheLohoped I'd have thought it would still be the KGB at that time, haha xD .
Zbrojovka = means Armory or Gun factory or Arsenal (weapons) . It could be keyboard from the S300 system or similar AntiAircraft/AntiMissle system, or other type military system computer :)
+1KeNnY1KeNnY1 Oh wow, that'd be awesome xD .
Talk about modular. Really!
Thanks for the video. These ancient keyboards are very interesting in my opinion.
+MechaniKey Thanks, glad you enjoyed it :) .
subscribed. you are so dry. I wish I could be that dry. I was in stitches when you said "Now I'm going to type some random gibberish." Thanks, looking forward to your next.
+skiwithpete Haha thanks mate, you should see my Remington review ;) .
The naming indicates a Reed switch keyboard, not a Hall effect keyboard. Reed switches were popular in Soviet industry. With the number and type of ICs they have on there, i really can't imagine it being a Hall keyboard with multiple key rollover, but a Reed switch keyboard is no problem. You can verify whether it's really Reed or Hall effect, by actuating the key sloooowly and listening for a very faint click, the click comes from the Reed switch leaves coming together.
They likely integrated multiple functions, as the keyboard was likely part of a computer, and rather than having the speaker specifically do the click when you press the keys, it would likely be wired to the computer for a software-controlled multi-purpose function.
Did you clean and lube every key even though it has no practical use?
+Flowmoshun Of course?! xD
What did you use to lubricate the sliders?
GT85.
This is only me nit picking, but the key that you pronounced as "BURK" is actually more like "VCHRK" because the first letter is a "V" and the second is a "Che". Great video anyhow, I have no idea why but I keep on watching your videos lately haha
Funny, someone else recently said they'd come to my channel after CS:GO gameplay xD .
Chyrosran22 RUclips's suggested videos system is strange, but I'm not complaining because I found your great channel! Keep up the good work bud - I literally know fuck all about keyboard key switches pre-2000, but it's still really interesting to watch ;) Pretty dank voice too bro
www.kompjutry.cz/soubory/prislusenstvi_html/cssr_klavesnice.html It's probably a consul keyboard missing the casing. Man those are cool. I think i have seen somebody making an interface for it to use with a pc. Sadly i don't remember where it was.(I am from the Czech Republic) They currently make Cherry Keyboards here, but they are still less expensive if you buy them abroad for some reason.
Oh yeah, btw. Both Czech and Slovakians have used the latin script since the 1000's. The cyrillic script on this keyboard probably means it was made for export to some Cyrillic writing country, probably the Soviet Union. Those are also much rarer than the normal latin variants. Soviets usually made their own keyboards.
vojtasTS29 how "good" were Soviet keyboards?
Хаха) кнопка ФСБ открывала прямую линию связи с дядей Вовой в те бородатые времена)))
Oleg Orlov Тут есть русские? Я думал я од н такой мудак, помешаный на клавах
Вишь, целых девять лайков на комменте
@Foreverzzv бывает
Uh idk
Very nice design. The chips are 74 series TTL chips.
I love how simple those switches are!
+! beautiful review! Insightful timetravel back to another era!
What lubricant do you use for lubricating mechanical keyboards cherry/gateron switches for us mortal souls?
I don't lubricate Cherry or Gateron switches. I used GT85 for these. but I'm not sure they'd work on MX-type switches. I've heard a lot of people say Krytox works best on them.
all the ICs have 74 in them because they're using "7400 series" logic
"The SN7400 series originated with TTL integrated circuits made by Texas Instruments. Because of the popularity of these parts, they were second-sourced by other manufacturers who kept the 7400 sequence number as an aid to identification of compatible parts. As well, compatible TTL parts originated by other manufacturers were second sourced in the TI product line under a 74xx series part number." though 74 logic ICs are still made using the CMOS process now
"Quickly replacing diode-transistor logic, it was used to build the mini and mainframe computers of the 1960s and 1970s. Several generations of pin-compatible descendants of the original family have since become de facto standard electronic components."

Subbed. I love keyboards and I am just getting into alps switches, and I will surely try to use them after I build my ergodox. (Massdrop shipping sucks). Good videos. You remind me of skiwithpete in the way you explain keyboards.
+Lord Slapz Never heard of him, but thanks xD .
Вызов теста - I lol'd, also bought 220V calculator with neon indicators and the same switches for $4 - just awesome feelings of the whole thing
Love these video's man. This looks like a board that does not have a solder mask. Instead, the copper is tinned to prevent corrosion. This technique would date the board to the 70s but who knows.
Mo'in Creemers it uses clear soldermask ;) . Glad you're enjoying the videos :) .
"burk" button is most probably actually v-ch-r-k (вчрк), which sounds like short for "вычеркнуть" (vicherknut), i.e. "cross out".. or, more likely, something doing with either backspace, or with applying formatting to text
Can you fix that kind of board and add an adapter for a modern PC? o_O
Build to last ...thx for the view of this keyboard.Will have to subscribe always fun to see how they used to do things..State Sponsored ahhh when things where build to last..instead of building to fail and consume in an endless loop ;-)
Great video! It's interesting to see how the soviet design doctrine of prioritizing durability/reliability above everything else (at least with things considered more essential) influenced soviet/eastern European products in comparison to western designs.
+Salvador Limones Well if the state pays for everything, they're sure as hell not going to have built-in obsolescence xD .
+Salvador Limones The Soviets ripped off a lot of the tech they used from the West. These are a rip-off of the Honeywell design. It's questionable whether the ability to dismantle the switch, though nice, added anything to the original design that has a 30 billion key-press MTBF.
+dalriada842 Massively! 30 billion is a useless figure if they get dust in them and start to feel like scratchy crap! ;)
Chyrosran22 I doubt the keyboard manufacturer gave a hoot about how it felt to the end user, as long as it worked. Communist central planning was far less concerned with customer satisfaction than their Capitalist counterparts.That's a concern for geeks like us!
Chyrosran22 It would be interesting to see how the internals of the Honeywell switches compare to these. Are they glued or welded shut?
This keyboard was probably from a dedicated wordprocessor or a terminal to larger computer.
As many of the NON-PC keyboards you have reviewed use simple 74XX series logic chips it would not be hard to interface to your PC or anything else you like as the connections, usually output ASCII in binary depending on how smart the logic is on the PCB.
en.wikipedia.org/wiki/7400_series
en.wikipedia.org/wiki/List_of_7400_series_integrated_circuits
74' series chips usually have a month/year 4 digit code. i see from the video none of your chips have a numeric date, could ''cemi'' be a date?
that looks late 70 early 80's to me
Why can't you use it? Is there not a way to adapt this. It would be cool if someone reproduces these, to work in place of Cherry, and modified the metal cradle to attach to a hotswap key switch bracket.
"By the way, IT'S FUCKING HEAVY!"
HAHAHAHAHA
How much did you pay for it and where did you find it?
+Celso Soares 20 pounds iirc, off someone from DT.
Amazing Keyboard, Amazing Video and Amazing Voice.
Thanks! :)
i'm loving yours review!
I would love to have a arrow keychain for 20~30 bucks, wonder it is on sale yet
+Lancelot V Ask him!
Chyrosran22 This is my first time auctualy go on a keyboard forum! I am excited!
Hey, do you still have this board?
Your russian is prety good, "Вызов теста" translate like "test call".
I'm so proud of your right thumb!
+Passive Hahaha yeah, don't worry, I'll be back to index finger next week xD .
After all this time, i noticed you used your thumb for the space bar in the typing demo!
great channel, i like this keyboard idea
perhaps you could do a vid on how the switches work ..these and the honywell...
+samdeur My ITT Courier video has a detailed explanation on how Honeywell Hall effect switches work, these work the same way. Check it out! :)
+Chyrosran22 awesome thx will do ;-)
Шикарно :D
I like your vids.
thank you
looks super interesting tho
pretty cool
You used thumb to space :o
Cool
still work?
Tesla Stropkov still exists
It would be insanely cool if you played Doom with this keyboard.
It's funny that you mention that, I tried to record some Doom gameplay on my computer just yesterday xD . But my computer chugged a lot while doing it so it didn't really work :( .
What are your computer's specs out of interest?
Also these seem like the AK 47 of mechanical switches (reliability, serviceability, ruggedness, and very Soviet of course ;) ), just a shame they're not as widespread...
It's a Core 2 Duo with a 560 GTX and 4 gigs of RAM. It's over 4 years old now I think.
Ah, yeah that's getting on a bit. There was a recent update to Doom
which added the Vulkan API to the game which gives a large performance
boost to AMD cards, so even on an older card you could hopefully still
get decent performance. You can pick them up for not too much on ebay/gumtree, go for a HD 7850 2GB (£40-60, same sort of power as PS4/XB1) or better. Second hand R9 290s offer some pretty serious bang-for-the buck too if you get a good price.
That's WAAAAY outside of my budget atm xD .
That's really cool man. Soviet sci fi keyboard lol.
It's not soviet tho. It's czech.
It's soviet. Can't you see the letters? It was made in Czech republic, but quite obviously for soviets.
BTW I am from Czech republic, so if people in my country used cyrillic script instead of latin script in the last thousand years, I think I would know. ;-)
Michal Valta It wasn't made in the Soviet Union, therefore it's not Soviet. When an Eunos is made in Hiroshima and then transported to EU, it's still Japanese, not European.
Michal Valta Also I am quite sure that it wasn't in fact made in the Czech Republic but in the Czechoslovak Socialist Republic.
Clearly, my next keyboard needs a BOORK (ВУРК) button!
BTC 5100C keyboard Please? Thank you if you do it, or if you don't do it. :)
Russian keyboard , nice !
yay, czech stuff!
Bob is not my uncle! Why do people keep saying that?!
The things you typed were actually nonsense (even when converted to QWERTY)
I couldn't tell you were typing "Hello my name is Thomas" at the start either.
ВЧРК is not 'BURK", its 'VCHRK' ('vicherk') XD
That space bar as it is would grind my gears. Not a lovely sound at all.
can you imagine buying a working keyboard with these switches weighted at 45 or 50gr ohh man how cool would that be..
+samdeur Someone apparently did actually get one of these working xD . Build a custom case around it and voila!
wow cool..
its not hard to get it working, all the momentary switches function the same NO or NC you would just need to use a controller board. and instead of using the conductor paths found on the PCB just solder some 16 to 20 gauge wire to create a connection between the switches and the board.
Are you sure it works the same way? The guys are having the hardest time converting the Honeywell Hall effect boards because they use completely different signals than other boards, working with pulses instead of conductivity and such.
Chyrosran22 yes im a electrician, i worked with low voltage control circuits before. a switches is going to functions the same no mater if its a relay, a mms, a no or nc switch such as momentary, hall effect, limit, float, temp ect... I really cant see how it would not work. i dont know too much about computer circuity but the logic and concept should be the same and in my experience it is the relatively the same.
All old keyboards' stabilizers are really bad
You are a lord troll. The most used meme on this channel is to make fun of freedom units.
And your scale? Freaking imperial xD
прикольная..
ага
for those who want to create a nuclear war in style
Most western slavics use latin alphabet for centuries.
Than again Zbrojovka Brno making electronics is strange, Zbrojovka basicaly means that they are weapons manufacturer (yes i know they made motrocycles before nazis took over)
