Somewhere around her, I have a ZX80 that also worked as a ZX81 by having an EPROM twice the size with one pin bent out and a switch on it. I did quite a few things with that very limited machine. I had a 16K RAM pack that I built attached to it. I even worked out how to do pixel graphics on the thing. Its amazing what you can learn from stuff like that
Brilliant. I still have my ZX81. I think it's amazing looking back just how well programmers were back then to write code that was so efficient with such limited resources
Hi, great review, thanks for that. I'm 62 now and I immediately bought the Sinclair ZX81 in 1981. So learned BASIC. Then came the Sinclair Spectrum, then the C64. Moving on to the Atari ST. ;-) What great experiences those were. It was a nice time.
I wish I still had my original Speccy, I have my QL and highly upgraded Amiga A2000 but have no idea what happened to my last Spectrum. My dad (a Snr Systems Engineer) made me learn BASIC and tested me before I was "rewarded" with a 16K ZX Spectrum in 1982 and Planetoids was the first game I got for it, I only played it for a bit of nostalgia using Fuse this Tuesday. He made me learn BASIC to encourage me not to use it just for games and I've been a professional Software Engineer since 1987 working on the code for avionic systems such as the Head-Up Displays (HUDs) for C-17, F-16, F-5, Eurofighter Typhoon and the fly-by-wire (FCC) for Boeing 777, all thanks to my dad and my humble Spectrum. "From little acorns..." as they say, but I never had an Atom, Electron or BBC Micro 😉
Great story! I'm very fortunate to still have my Speccy. It got put away when I finally got my Atari ST. But me being as I am not being able to part with anything, it went back in it's original box, just waiting to be loved again 😊
Oh the good old days. I cleaned up in school selling cassettes loaded with specy games. Self-taught sinclair basic from mags and books, took for ever then they scrapped it.
i got my speccy in 84 but when we opened the box it was scratch to bits. so mum took it back to Rackham's the day after boxing day and they replaced with a spectrum plus. it was worth the extra few days wait
Marvelous ! I enjoyed you video , made me think of my wonderful Mom too. I still have my Sinclair. I was studying electronics at the time and in order to learn assembler we were given a choice , buy a pcb with Z80 on it called a Micro Professor (looked like a book) or get a ZX Spectrum. The Sinclair made more sense. Went on to learn Basic and the road to programming and code opened up from there .
In 1984, I was in my twenties and happy about getting a job at a high tech firm that designed and manufactured semi conductor manufacturing equipment. These machines were used to make the IC chips that are in a Spektrum and other computers, along with everything else. Going further back to my childhood, I never received Christmas presents because of my family's financial situation. I can only imagine that as a child it would have been exciting, but I don't really know. I still loved my parents though.
Thanks for that comment. It's great hearing how this vid brings back your memories 😊. I'm really glad you liked it. Have a wonderful Christmas and new year
In the early 80's i worked as an elecronic technician (Tea boy for the engineer) designing and building prototype mainframe machines for Burroughs computers now Unisys. One of the engineers came in with the advert for the Speccy we all (about 15 of us) went OOH! AAH! WOW! and more. I bought one about 3 weeks later from, I think,, WH Smiths. That meant we had 3 in the department and I recall not much real work happened for some weeks after this as a lot of reconfiguration was done to our 3. digital video output, to use with our monitors. A very basic floppy disc interface. More memory etc. This might be part of the reason the plant closed! But great memories. The plant closed in 1992 and for the last 6 months our team spent the WHOLE time playing Lemmings on home built PC clones. Sorry about going off the rails here.
😂 Thanks for sharing. I really appreciate the comments (otherwise it's like talking to a black hole). I hope you enjoyed the vid and it brought back those happy memories. All the best for the new year. Simon
The ZX 48k is still in the basement somewhere. Built a joystick interface myself, played a lot of Jet Pac, many hours. Been working in IT most of my life.
Brilliant 😍. Jet Pac and Manic Miner are my go to games (predictable but who cares 😊) oooh and Chuckie Egg and Robin of the Wood and Star Quake and Turbo Esprit... 😂 Thanks for the comment. Have a great new year
i had my zx spectrum rubberkey in christmas '84 , i later got the 'plus' upgrade keyboard and fitted it in that, still got both, i got an interface 1 and 2 in the 1990s from a car boot sale , the rom games were always expensive and they certainly are more so now! i recently made my own rom cartridge board that uses just a single rom file 27c128, but not yet tried it, , that 27c512 board could be very useful as i was given a load of programmed but never fitted 27c512s some years back
It's great that you still have that Speccy. Good luck with the 27C512 EPROMs. It s a super simple board to throw together 😊. Thanks for the comment and have a great new year
My mum was actually angry that i bought a silly stupid computer, which was the zx spectrum. I learned basic but also assembler. Together we wrote a printer driver in assembler which was residing in the spectrum printer buffer memory space (not an easy task due to the small printer buffer size) It used the beeper with a transistor at the output to create a unidirectional serial interface. We hooked up an HP line printer which we bought from a scrapyard for almost nothing and yes it worked ! We also hooked up a real computer monitor and a real keyboard. The speccy was housed inside the computer monitor housing. Everything was looking super professional 😂😂😂 (fortunately we had a computer scrapyard nearby who sold old computer equipment y weight) I am now an electronics engineer, still passionate about small computers and microcontrollers.
Been hardware hacker for as long as I can remember. I began by adding a 8255 PPI to my Spectrum and then adding some circuitry to that to provide me with the capability to program EPROMS. What I would have given for the capabilities we have in microcontrollers these days back in those days.
@@RetroComputingReboot it is a peripheral chip which creates extra IO lines. You also had the 6845 which was a crt controller chip. And there were a bunch of different chips out :).
I remember sending off £125 for my Spectrum (16K) in 1982 then later upgrading it myself to 48k. It was known as an Issue 1.5 (rare) meaning it had the Issue 2 Pcb with the original 5C102E ULA and the dead cockroach IC stuck to the top of the Z80.
i liked your video and ypur christmas story about the spectrum and you mom! thats awrsome.!my favorite was1982 mom worked very hard and got me a colecovision!! my favorite christmas ever!! i live with mom to help her out with things. i love mom! and i bet your moms happy she has a good son!merry christmas simon!
Did anyone here go in to shops back in the day, and type 10 PRINT "(Some obscene message)" 20 GO TO 10 RUN on some of those 8-bit machines on display? When I got my own Commodore 64 in April of 1985, I learned how to use its sound capabilities (which routinely made Speccy owners green with envy! 😎), and did a bit of BASIC code which mimicked the boot-up screen, waited either for a keypress or just a few minutes to give me time to leave the "crime scene", and then made some loud siren noise (don't forget to POKE 808,251 to disable the RUN/STOP key 😛) Later, when I mastered machine code/assembly, I had a little routine which waited for the cursor to leave the leftmost column on the screen, and then sporadically "press" the DELETE key, frustrating the next bloke who came in to do the PRINT "(obscene message)" thing. Nowadays, computers in shops just run an advertising video or slide show, and demand a password if you want to do anything else with them. Today's kids will never have the same kind of fun we had...
Brilliant 😍. Yes I was there myself. There were loads of independent computer shops in the day which I loved to visit, but they were more savvy to that malarkey. However, the big chains like Currys and Comet in the UK were much less clued up. Juvenile but funny 😂
I got my 128+2 speccy with a joystick, Soldier of Fortune and Fire&Forget, just a few months before christmas. At the time, it was being sold here just a few quid short of a minimum wage, and my dad was the only one working due to my mom doing chemotherapy. During that time I hardly saw my dad for almost a year because he was doing overtime in construction even on weekends. I can not even imagine the effort he made to make it possible, having to support a house of 4 and paying for experimental treatments. I don't remember if he got anything for me and my brother on that christmas, but we already had what we wanted, really. I still have it, and just waiting for a full refurbish, which I will do as soon as my workbench is free for a couple of days.
Nice. I am way too old to have received a computer for Christmas, but I can imagine the excitement. At the age of 74 I have just bought my first retro computer, a BBC Model B. Had it shipped from the UK to the US. I got to play with it for a little while, but now it’s packed away pending a 2000 mile move from Georgia to Nevada.

@@stevesgaming7475 Thanks Steve. I hoped it would appeal to Speccy fans. You can never be sure though. I'm really glad you enjoyed it. Have a brilliant Christmas 🎁
We got our Speccy some time around July 1984, we couldn't wait until Christmas. LOL. That's a different version of Planetoids to mine. It all looks and sounds the same apart from when you get hit. My version just has a magenta (sort of) polygon where your ship was. Odd.
@@RetroComputingReboot I never stopped programing the ZX81 or the Speccy. About 6 years ago I upgraded my original ZX81 to 32K internal RAM. About 3 years ago I installed an SD card and joystick expansion PCB, soldered to the expansion port. LOL. (I had to instal a new ROM in the 81 to use the SD card functions) A happy new year to you too.
With those rom carts, a cheap interface 2 remake would be interesting. It should not be hard or expensive, as there shouldn't be many components needed.
I suspect you're right there. I'm not completely sure. However, you can get modern recreated rim images from tape files such as Jet Set Willy which must be over 16K. Perhaps someone else knows? Good comment though, thanks. Have a great Christmas and new year
@@RetroComputingReboot yeh you are limited to 16k images as if you tried to to access a higher memory address with the cart it would cause problems / corruption . but there are more ROMS available that have been adjusted to run as 16k and there are other options of using bank switching and altered snapshot files to load a 16k bank into ram then switch bank and load another 16k but needs a little hardware + coding. i did try it on a breadboard manually switching the ROM page which to my surprise worked .. some boards use a resistor /capacitor delay to switch the bank page after a short time ..
@gdutfulkbhh7537 Yeh, it's a shame really as it's soooo much better than loading from tape. But if it wasn't for being 'cheap' I guess the Speccy would never have had the success it had. It's strange though to launch the Interface 2 a year and a half after the Speccy launched. Hope you enjoyed the vid. Have a good Christmas and new year
