I always thought 386dx-33 systems were pretty elegant back in the day. They were not mass market low end like the 386-40’s, wishing they were something better. Northgate workstations. Compaq servers. I don't know if they could be considered "high end", but there were a few decent 386-40s sold in 91 …

I owned this board over 25 years ago. I got it second hand from a friend of a friend. I am pretty sure either it came with the manual, or I had the PDF manual for it. The board is long gone, but it's possible I might have the pdf manual on one of my burnt CDs from the late 90s. I'll try to have a …

Good job tracking down the problem. In my experience integrated chipsets are rarely the issue. More often than not, it's due to a severed trace. One thing to check for in the future is to see if any arsehole dropped their screwdriver somewhere. I've seen that a few times.

I think I have the same PVGA1A card. I've only ever tested it to see if it worked (it does). Is there anything special about it? I've been using VGA Wonders for years, and never had an issue with them. The way I see it, if you want to play crappy CGA games then just get a CGA card.

Despite the extra cache control lines, a number of people on VOGONs have had some luck with 386DX systems and the IBM 486DLC3 (the 32-bit version of the SLC2). I'm not sure why this works exactly. Perhaps the boards are new enough to have already built in some support. Desoldering a 386SX and …

I think the 12MHz AMD has a decent shot at 16MHz. I believe it was the last 80287 developed, so it should use a fairly modern process. Just try not to ruin it, because as I said, the 12MHz part is not all that common in DIP (I've seen them more often as PQFP44). I think this Tandon could actually …

You have a weirdo ALi 1429 386/486 hybrid chipset which is natively ISA/VLB. The PCI has been tacked on with a bridge chip. Where did you get those cache modules? Are those original? BTW, your warranty has been voided.

Not just the failed stuff, but sometimes after new products are released, formerly high-end stuff becomes unwanted in the domestic market and then dumped some place else. I found plenty of high end parts in former soviet block countries.

The only PC upgrade I know of is NEC v30. There was an odd one saw long ago had a 80186 cpu on a card and a ribbon to a socket and think it worked for both 8088 and 8086 but was proprietary. An industrial application at Tektronix back in 80's and ran cp/m-86 or some such thing. My neighbor gave me …

I think these are 1MB cards. The one on top seems to be newer and has a beefier RAMDAC. If you're going to keep one, keep that one. I really like EISA stuff, but these days I wouldn't go out of my way to buy a board unless it was cheap. My feeling is that this card would be best at home in a 386 …

My guess is they're Gold top chips, as John wrote in the thread on CPU-World, the full ceramic chips had heat issues, and as such were produced for a short period of time only. You're probably right about the replacements being gold tops. I didn't talk to John, but I looked through a bunch of …

More VLB cards degrades signal quality and possibly causes stability problems. It shouldn't make things slower unless you add wait states. If you have a well designed board, and well designed cards you can sometimes exceed VLB specifications without issue. Isn't the OPTi 895 one of the 486 chipsets …

My reading skills must be poor. I didn't notice that you already mentioned with board you have further up the thread. Your board seems to be modern and of decent quality, so it seems that should not be the reason you card can't do 0WS. One thing I noticed which is a bit odd is that your DIP RAM …

Most LIM4 and EEMS boards only allow you to backfill down to 256kb. The purpose of my experiment was to see if the entire 640kb could be backfilled. Perhaps with the right card/motherboard combo it might work? I think I also tested this with an Orchid RAMQuest 8/16. That's a SIMM based card that …
