Did you ever do an update video about connecting the switch. I just can’t wrap my head around how the wires go to the switch could you please help I don’t know if you have a diagram or white wires go to what poles or what but anything would be very helpful. I was going to buy one from your side but it looks like it’s out of stock for the ST to VGA switch. If you had one available, I would certainly buy it but since you don’t could you provide any additional information how to get to switch up and working. Thank you so much. Keep up the great work. Your show was awesome.
Fun fact, the pin spacing of the 13 pin din is the same as the hole spacing of pre-punched experimenter's board (with the exception of pin 13) and the rest is the same as a common 5 pin din, so if you are reasonably handy you should be able to make your own 13 pin din out of stuff you might have lying around like I did......for me it was quicker than ordering one and waiting for it to be delivered.
I had luck using the Norcent LT2025W 20" NTSC LCD TV to lock to and properly display low/med/and high modes through the VGA D15 port. Hard to find them these days but perhaps others in the same family would work. I picked mine up pretty cheaply two years ago
My English is Bad - I'm Boy from Germany, i write follow in my Language: Ich habe einen gleichen Adapter hergestellt, aber ich habe dabei auch an Audio-Signal gedacht und das Ganze gleich in ein Gehäuse gebaut. Sicherheitshalber habe ich bei meiner Schaltbox auch den Pin 10 auf VGA Seite (Sync-GND) mit den Pins 6-8 (Color-GND) verbunden und an GND Pin 13 (Atari-Stecker) verbunden!
From what I've read you should always turn off between switching. I've got a switch between VGA and RGB SCART. I hook it up to an all-in-one TV/monitor.
+FairFight14 Sounds like the simplest option, I have the schematics, I will let you know about the turning off between the switching when I study them 😀
I like the idea of an all-in-one VGA switch though, because then I could pass it through a VGA2HDMI box. On that TV/monitor, I have more control over the HDMI input ratios. When I've tided stuff up, when I'm finished with my Amiga, I'll DM you some photos. Just so you get to see how at least one of your followers has things set up! :)
+FairFight14 I some HDMI boxes waiting for me to play with, I will let you know how far I manage to get 😂 really, I think I'm not too bothered about hi res mode, I only used it for productivity stuff and very likely to do that these days with my ATARI ST. 😀
Nah. My father had made a similar switch for me, not for one multisync output but with one Atari output connecting to my monochrome Atari monitor and the other output going to the SCART socket of a color TV. It had a large mechanical switch inside with many poles in parallel, probably switching all lines, not only the necessary ones. Worked great and kept me from fiddling with those plugs whenever I went from work to play or back. So, toggling the detect pin does trigger a reset but the Atari itself doesn‘t care. There is no such thing as properly shutting it down. Everything is just in RAM. You just reset or even power cycle the machine and it boots up again freshly. That‘s the way things were meant to be done in those days. Theoretically that setup could have been a problem for very old fixed-frequency monitors, because there could have been a brief moment when the TV got high frequency sync signals or the HiRes monitor got low frequency sync signals that were outside of their specs. But that wouldn‘t kill them. Newer monitors had protective circuits that would just cut off those signals and show a blank screen, sometimes even with a message "out of sync". Older screens would not check the frequencies and try to show that picture which would result in a distorted display, often accompanied by an unpleasant high-pitched noise. This probably did stress some components inside the monitor, coils and capacitors might heat up and eventually die within minutes, but they wouldn‘t go Foom instantly. But since it would only be split seconds that a screen got its wrong sync signals that was no problem at all.
So there wouldn't be any problems if id turn it around? (connect the Atari monitor to my PC) Edit: Well not 1:1 (i wouldnt have to connect the connection for high res and low res) but i could connect simply ground to ground, sync to sync and Colour to Colour, right?
To get rid of the banding, it's usually a clock or phase adjustment that's necessary, if the monitor itself is up to the job at all understanding the rather different frequency. I got my screen to display monochrome hires perfectly without any banding, but that's done on a AG Neovo RX-24, which offers very deep control over basically every setting and (according to the manual) supports the low 15 kHz frequency.
Possibly, I use a Dell particular monitor that was recommendd to be that send to contain all the magic runes and incantations necessary to display most things
It's a fantastic way to explain this as simple as it possibly can be!
Awesome, made mine today

Ha! I got your Tony Hart reference there at the end when panning over the paper! ;-)
+EgoShredder I think you were the only one!
Do you have a pdf of thid available? Sorry , I am def and dont know if you said so… this is awrsome. Thank you!

+Enemy Sub that really is interesting! Because our usually just prototype and run, waiting for parts really is a chore!
Actually its not a 4 way switch, its a 4 pole, 2 way switch.
Great Video but i dont quite Under stand you Plan. Is 1 from the VGA always connected to 6 7 and 8?

Great tip, thanks!
hehe that made me lol when you shook the paper about after scrolling it and saying we could puase the video

One additional remark: what's with pin 5+10? (I thought pin 5+10+6+7+8 should be connected with GND)
Good job! You could also use a converter board with the RGB->VGA cable to produce a proper signal for non 15kHz monitors! (e.g. Gonbes GBS-8200)
Can you help me to make
RCA to vga converter cable
So there wouldn't be any problems if id turn it around? (connect the Atari monitor to my PC)
Edit: Well not 1:1 (i wouldnt have to connect the connection for high res and low res) but i could connect simply ground to ground, sync to sync and Colour to Colour, right?
Thanks. How about converting an ATX PSU to ST? Normal ATX won't inside the ST case but picoPSU will.
Interesting, like www.atari-forum.com/viewtopic.php?t=23488 ? If mine ever die, I will try it
Yeah. Will interesting because without the PSU, there will be plenty of free space for other mods.
Wondering if taking pin4 low gives hires on the uhf tv output or just the monitor?
I'm pretty sure it shuts down RF output
does anyone make an adapter to allow me to use a SC1224 with an EGA Graphics Adapter for A 386 DX40 IBM/PC? (EGA not VGA)
What if you want to connect a pc vga connection out to a 13pin din connection on an Atari sc1224 monitor?
That's an interesting question, so to use the ST monitor like a PC monitor? I wonder if that is in spec for CGA or EGA modes
your monitor gives same banding mine does in hires. wonder if the st freq is a little non standard?!
+Meth Methanoid it gives banding on a bunch of monitors. I think it's just not really compatible with VGA. I will see what others have achieved.
To get rid of the banding, it's usually a clock or phase adjustment that's necessary, if the monitor itself is up to the job at all understanding the rather different frequency. I got my screen to display monochrome hires perfectly without any banding, but that's done on a AG Neovo RX-24, which offers very deep control over basically every setting and (according to the manual) supports the low 15 kHz frequency.
Trying to find that switch. EBay no good. CPC? Special keywords? Thanks Andrew
www.ebay.co.uk/bhp/toggle-switch
LOL, score one for Andrew.. but seriously.. is it something like single throw 4 pole or what?
It's a 4-pole Double Throw switch. Usually that translates to FPDT or 4PDT (Four Pole Double Throw).
Always as entertaining as it was educational :)
We salute the fallen ATi graphics card gloriously sacrificed to make this video possible 🤘
+Simon Lock I am so glad I have the shelf of curiosity to fall back on when needed!
:D
The majority of my initial video cables start life in a similar fashion to yours until either a proper one arrives in the post or I do it properly.
+Simon Lock You need to walk before you can run 😀 experimenting is fun
Indeed - my first one was powered up via jumper wires that I was creating in real time (not recommended) :D
None of this is workin except mono
This does work, but remember modern monitors are less likely to support the frequencies the colour RGB output works at (15Khz).
thanks for reply, monitor was only 25khz, my fault!
It's tricky, so few support it, however you can use a TV with a VGA port and use the VGA for hi resolution and the scart for RGB
en.wikipedia.org/wiki/Multisync_monitor
Shouldn't EGA monitors support 15.7kHz?
And VGA Monitors most often support EGA.
Possibly, I use a Dell particular monitor that was recommendd to be that send to contain all the magic runes and incantations necessary to display most things
