One people told me, he has difficult with 64MB RAM and Trio64V+ VLB. Their system run stable (Gigabyte with SIS471 ), if he use only 16MB RAM. I think and can say why: Adress decoder from STB Powergraph P64V (same as my relica ) respond at 0-8MB and it is mirrored at 128/256/384MB (and more memory …

It is very depent of board. I have check with Abit AN4R307 (a AN4TR2 without 3.3V Support) in most case ist distance zero, only DOOM is ARK a bit faster. (61,47 FPS versus 61,78 FPS ) It is checked with DOSbench from Phil. Same with ASUS VL/I-486SV2GX4 (Rev. 1.7) by a guy. (He has also ARK1000VL and …

Yes it works, if you load ROM image to upper area (because highest address pin is on VCC , while this pin on 27C256 is VPP-input) Duplicate of rom image works also well. regards matt

My Mouser shipment arrived today. For those also putting in an order, be aware that the VGA ports don't appear to come with the stand-off screws. So if you don't have any, you'll want to source these as well. Ooops, yes, bolt/screw for mounting of pc bracket. I have forgotten adding him into csv- …

For the most part, I just ordered exactly the quantity I needed, except where it was cheaper to order 10 pieces. 100 pieces is more ideal, but I'd have no need for them. PCB's arrived very quickly and look slick! Gold for all solder points? Interesting. Probably is a good idea to keep the gerber …

yes, your notice about 64bit bus is right, but it is not important for performance in DOS-Game (because it use often only 16bit Memory bus ) (except VESA Mode) Trio64V+ with 0 WS is fast as ARK1000VL in VGA/letter-mode. By Windows-acceleration is Trio much faster than ARK and Vision96x is superior …

But, i must tell: STB Powergraph P64V runs with Waitstate 1. If it is setting to zero Waitstate -> ARK1000VL Hunter. Despite stable run in Win95 and DOS, win 3.1 didn't like zero Waitstate (graphic failure with standard VGA Driver) Motherboard with SIS496/7 doesn't work with 0 Waitstate. I attached …
