One last HW change: I have replaced the S3 Vision864 PCI VGA card (only 2MB detected in the end) with an S3 Virge 4MB card, just because it looks neater and is slightly newer. Also PCB design supports no capacitors that could go bad (same with the S3 Vision864 though, but it is a point of concern …

I would suggest VGA - definately some PCI card, almost any would be faster than ISA card HDD - would advice to go for an SD-to-IDE adapter , rather than CF. I had lots of trouble making CF-to-IDE work in my own 486 and post, and what helped was getting an expensive Industrial-grade CF card (55 USD). …

This is definitely gonna mess with video signal quality but most importantly it also messes with keyboard and keyboard controller since in disconnects them at any random points. Thanks for the remark. I am so intrigued that this morning I pulled the plug and placed an order. With it I ordered DIN …

Hi all, I am intrigued... I have two retro pcs (486 and MMX200) and I would like to interface with both of them through just one mouse/monitor/keyboard. This switchbox off Ebay seems to be able to do the trick. s-l1600.jpg I just seemingly need to get two sets of pass-through cables for VGA (M-M), 5 …

Hi guys So I decided to not pursuit the dual booting and stuck with default Win95 boot. I went with S3 Vision864 PCI VGA card (4MB) for video and SB16 CT2980 for audio. Only trouble after that was figuring out the sound card's IRQ/DMA to set for each game and I am done! Today I finished putting …

I should focus on some cooling now of both of these cards, they both get pretty hot during gaming. I wonder how two Voodoo 2 cards in …
