I'm not too sure, while there are many cheap AGP cards that can be grabbed for next to nothing, the CPU won't really make a good use of them I think
Also maybe I'm misremembering, didn't you want to leave the mini pcie video card as an option ? Because then that would mean you could use the PCI slot for other kind of expansion cards 🤔 (Ignore this if that mini pcie port is a fever dream of mine).
Meanwhile I've done some progress for the CD-Rom thingy !
The hardware isn't even here, but while I'm waiting for it, I started looking at the DOS part. I talked about this to other people and they gave me a better idea. Instead of hacking SHSUCDX, I'm making a TSR ! Last night I managed to make a TSR that responds to the play track, pause track and resume track commands !
It's not finished yet, I need to figure out how to output to serial in x86asm/DOS, and for that, I'd love to figure out how to connect a terminal to DOSBox' serial port because that would make my life so much better 😅
Also I've had another idea for it. Instead of using the serial port (I'm still planning on making a serial port version of course), why not use midi ? That way I can make a "wavetable wannabe" that connects to the WT header and outputs straight to the sound card, or connect to the game port on the back of the PC, which does provide 5V power, unlike serial !
However I need to study midi itself a bit more, because the last thing I want is something that would mess with existing wavetables 😓
