I see 80286 was available in PLCC/PGA/LCC packages. Any information about which of these were most common on generic clone motherboards (with a CPU socket)? In 1980s/in 1990s?
Also what could have been ratio of soldered on to socketed chips on those?
I've looked at motherboards for sale recently and most were using PLCC, few PGA ones I saw seemed to be for some PCs with non-standard cases, don't know about LCC....
And I usually see XT motherboards with socketed CPU, but 286/386/486 more often come with soldered on. Maybe just the selection I saw. Did it became more common in early 90s? As kid in late 90s/early 00s I've heard some people say that "all PCs before 486/Pentium came with soldered CPU" 😲
And what about 80287? 😀 How common was a coprocessor with a generic 80286 machine? What was timeline of 80287 6Mhz/12Mhz/XL/etc.? Which non-Intel variants were popular in what time (same question about CPUs btw 😀 )?
