@@andystandys Well if it supported composite output with artefact colours like a real CGA card, it would have offered a unique feature. But this CGA doesn't. There's a reason not to use a VGA or newer card though - they are wrong. CGA and EGA scans out 200/400 line modes at 60Hz while VGA scans them out at 70Hz, and all the other timings are different. However the abundance of EGA cards really isn't there, so one gets what one can i guess?

@@johnknight9150 I had 4x 256 KiB RAM with 80 ns in that machine. So a total of 1 MiB. The VGA card had 256 KiB VRAM. Unfortunately, I don't know whether the motherboard chipset was able to move the RAM between the conventional memory area and 1 MiB to a higher area above the UMB, like some motherboard chipsets were able to do. The 286 components were sold rather early when i was too young as part of an upgrade, so the details are unknown to me. I didn't have a soundcard at that time, so 640 KiB should be enough to run Wolf3d.

My early foray into the exciting (!) world of PCs was an XT compatible in a very sturdy metal case with hinged lid, and a Hercules screen, and there was some TSR software available that could run CGA games on that PC, by dithering the colours produced by CGA so at least they could be differentiated. It wasn't great, but wasn't too terrible either. Surprising what can be done with limiting hardware really.

I was looking at the data for this board a couple of weeks ago - I would expect it to be very accurate because it's basically the original hardware recreated in a couple of CPLDs with the only significant change I could see being the replacement of the original dynamic RAM storage with SRAM and the resulting necessary changes to the RAM address multiplexing. Interestingly it still has the original logic to generate RAS/ and CAS/ for the DRAM, although they obviously aren't being used for anything any more.

They're there but they're all modern SMD type. 10 resistors and six 47p C0G capacitors form a matching and protection network in the bottom right corner of the card for the video output, and then there's 17 0.1µ X5R/X7R type capacitors strewn about the card to support the power rails on all the ICs and avoid too much compensation currents, most of them are hiding under the ICs in the sockets, which is a good placement. Due to low impedance of both the modern caps and the placement, this should actually be a low noise design, in spite of low seeming total capacitance. Seems competent at a glance.
