Re: [vcf-midatlantic] What would have used 64kB Simms?

256K SIMMs were used in the Macintosh Plus and SE 1MB models, and I think I have a 386SX that also uses them. On Sat, Feb 14, 2026, 9:03 AM John Heritage via vcf-midatlantic < vcf-midatlantic@lists.vcfed.org> wrote:

I'm going through some old stuff I have, and came across some 64 kilobyte and 256 kilobyte simms.

The earliest Simms I really remember using were 1MB for 386/486 computers though I could see 386s using the 256kb.

Earlier than that I've touched a few 286s with sipp and simm slots, but even they were typically aiming for "the full 640KB". But most XT/286 products I touched had individual ram chips socketed or soldered on board.

What devices would have used 64KB Simms back in the day? There are 9 chip as well, so I assume parity.
