Re: Replicas of Covox Speech Thing, FTL Sound Adapter and SiliconSoft SoundJr

if it's a passive DAC, can it just work with the same drivers & softwares as the covox speech thing? It is fully Speech Thing compatible. The only difference is the additional functionality, namely that it can be detected by software and that it has a joystick port. does the serial port have full …

I just recently found this topic. I was wondering how hard it would be to make a PCPplus driver for the Lucasarts games? I have actually looked at "The Secret of Monkey Island" before. The main problem I see is that there aren't any drivers, at all. Presumably it is all in monkey.exe itself, which …

Does the system still exist, i.e. can you find out which type of video card is installed? There were indeed a few any-standard-on-any-monitor cards that could display CGA graphics on an MDA monitor. For instance, ATI had several in its "Wonder" series of cards.

Re: Can an EGA card produce a double-scanned video signal?

My current hypothesis is that EGA cards that do not have a 16Mhz clock generator (like the one my CGA card also has), are not capable of creating single-scan video. The EGA cards I know can produce single-scan video all have such a generator. That sounds fishy to me. IIRC, the 16.257MHz pixel clock …

I am not familiar with that particular card, but the ATI EGA Wonder 800+ that I have is basically a VGA card minus the RAMDAC. If yours is a similarly late EGA card that actually uses a VGA chip, the double-scanned 400-line EGA mode is essentially a free bonus.

MDA monitors could also be driven with an EGA card. The result was a 640x350 pixel mode with three shades, including black. It could also have been a dual-frequency screen, though. That would indeed support CGA graphics.

So my thought was, simply take a 3-D printed generic bracket and drill 3 holes in it for the inputs/outputs. Does anybody sell something like that? I had no look cruising ebay. What speaks against the obvious, i.e. drilling holes in an ordinary low-profile bracket? If it is the absence of mounting …

If you don't want to open the PSU, you could still try to take pictures of the PSU board with a mobile phone camera through the ventilation holes. Maybe you can spot something that looks obviously broken. I used that technique on an ATX PSU once.

The way I read it, llm wanted to imply that you could perhaps reuse the Allegro part of that player in combination with decoders from FFMPEG. You would have to dive a little bit into Allegro's source code, though.
