Well, this thread ended up a lot more interesting than I had anticipated :) Just for the record, my initial question was to have this "super card" work with existing software (i.e.: as a way to accelerate the existing games). Anything that would require rewriting code would be a nice theoretical …

Hi, With the announcement of the FURY FPGA GPU card, I was thinking... would it be possible to create a new ISA graphics card using an FPGA (or a Raspberry Pi) that would make it sufficiently fast to justify the work? Although I know not all graphics cards where made equal, could a significantly …

I am a mixer enthusiast so your sins are absolved LOL I consider having an external mixer a must for any dos system with more than one sound outputs now if only Serdashop would work on releasing an 5.25" mixer .... ;) I agree. I could not live without my Mixer (I'm using a MAMX 1 from Moukey)... I …

Sorry for the long delay, but life got in the way. I have a quick update on this topic... the problem was on my physical Sound Mixer (it was set to mono - probably the cleaning lady changed it and I never noticed) and It never crossed my mind to check because I've never used that button in my life …

And now, for a plot twist... After much troubleshooting on the PC, config changes and countless reboots, I decided to "follow the cables"... and although the cables were all good and well connected, that led me to the mixer I have on my desk, and I noticed it was set to mono (must have been the …

I actually cannot think why this could happen if you don't select SB16 or something... if it was a hardware fault then the output channel would not move L<->R depending on "stereo reverse" option can you try on a normal ISA system? Yeah, I agree... it is strange. Unfortunately I do not have an ISA …

I'd recommend the usual suspects: - Check for resource conflicts - Remove all extra cards and accessories and see if it stabilizes - Add one by one - Try moving the boards around (try other slots when possible)

Does the Compaq System Configuration Utility (I assume you have a copy given that its an EISA-based machine) not have a menu option to create new .cfg files using user inputted settings (similar to what IBMs equivalent utility used to allow). It does, and it solved the issue. I just had to create a …

Alright, got it to work using the inbuilt CFG file creator in the BIOS. :) Now, I am facing a weird bug (?) I don't seem to be getting any sound from the right channel for digital soundFX - the music seems to come out of both speakers without any issue. What's even weirder is that in Duke3D's setup, …

I'm not familiar with Realms, but are you saying the game sounds different from the YouTube video you watched? And only the background music, not the main theme? Or are you saying some channels seem quiet but that this could be correct? Interface isn't going to be relevant if some channels and some …

Hi, I have a Gen1 MT-32 and recently realized when running the game "Realms" that during the game, channels 3 and 5 sound very quiet (volume:49 while the other channels have a volume of 74) . I even went to a Youtube video to make sure it was different from what it should sound. The strange thing is …

On autoexec.bat I found that if I redirect the output to the console (using the ">nul" command after each line) I can avoid seeing the verbose, but on config sys I am not aware of anything similar I can do. Let's make something clear: " > nul" doesn't redirects to "console", but to "null device", …

This 50 MHz (25MHz) board which you put another crystal on, and is now running at 66 MHz (33Mhz) likely has a bus divider of 6 (3). This turns your (E)ISA bus clock from the standard 8.33MHz into a clock of 11MHz The board with the original 66Mhz (33MHz) CPU likely has a bus divider of 8 (4) This …

glitchy cache would crash the system, while this distorted picture suggests VGA not liking faster bus somehow. I would argue the issue does not seem to be with the graphics card running at the higher FSB (I have another card with a DX2/66 that works flawlessly with that same VGA card). I would …
