< Lucky you. I have a couple of 1822 (CMOS RCA part) and a few 2101's.
< have not yet found a source of 50 to 100 256x4 2101-compatible SRAMs.
< I do have a pile of 2114's, but I'd rather use something else.
Those 2102s and 5101s are also 20 years old! I got them a while back.
Mine, too. My defunct former employer used to make a 68000-based serial board
that started out with 32K or 2114 and 2 6309 PROMs (the same ones as used
on the Apple ][ disk card).
What's wrong with 2114s? I've used them in a
lot of projects and products
and they fine if a x4 orginization is handy. I have 24 of them in use
for a intersil 6100 (12 bit pdp-8) based system.
Any schematics? ;-)
< The 1854 is still in production by Harris. I do
not think that the 1861
