Description
Memory mounted to an old ancient Everex Systems Inc. memory expansion board/card.

These were used in the old IBM 8086 and 8088 business computers in the early to mid 1980's. This particular board is stamped 1985 and I used it in my very first 8088 I brought home from work back in the late 80's. The difference between the 86's and the 88's was the addition of a math coprocessor chip in the 88's to help mitigate the work load on the main processor chip.

btw after the 8086's they renumbered them as follows...

80286 = 286
80288 = 286 DX
80386 = 386
80388 = 386 DX
80486 = 486
80488 = 486 DX
80586 = Pentium
80588 = Pentium
...

So there you have another bit of absolutely useless information from a bygone golden age of early computing into the advent of what we now call personal computers (pc's)
