Let me get this straight. You are essentially asking if it helps to use a Sata drive on a VLB controller for your paging file on a 386, yes? ... :] TLDR: there is nothing that would run well on a 386 and require more than 8MB of ram. Same deal with 486 and ~12MB of ram. There we’re definitely …

Never!!! What surprises me is that there seem to be 100mhz ones. Wonder if there are any 90 or 75s? 🤔 There was a period of time when a P75 was the only low power notebook pentium CPU, so I would bet that it’s possible unless p75 laptop chips were in normal packages. Though, as a golden tiger I bet …

Yes in the realm of ZIF sockets, both Socket 3 and Socket 5 were notable for this as well. Especially Socket 3. I'm not sure if Socket 2 eve support anything other than Intel chips, or rather if anyone made any chips that were compatible. Socket 6 was very short lived iirc and likely has the same …

The 32-Bit physical address space can be used for all kind of things, not just working memory. It can be used for memory-mapped I/O, too. Which was the primary use of the address space and the “big deal” coming with the 386 era and became one of the main features that made Windows 3.x become more …

So what should I look for on ebay, will and work? And for the socket, I can't find a match really. Technically an Intel 486dx4-100 OVERDRIVE should also work fine understanding that you need the 5v chip. (Overdrive) At higher expense there are also special voltage regulated AMD & Cyrix 5x86 …

There were scenarios where rather large amounts of virtual memory on a central x86 server would point to various POS “terminals “ and other resources. I am uncertain if any true x86 datacenter systems existed in the 1980’s but those could have 4gb of (physical + virtual memory) online even in the …

I have encountered old 128kb and 150kb video cards The 128kb one was labeled as if it were VGA, my guess is EGA, MCGA at best. Given the rarity and the likelyhood these were at best not fully VGA, I don’t think they are worth worrying about unless EGA and proprietary devices are of interest
