Yeah, I saw those (at Active, right?); in fact here they were 5 for 10 cents. Bought a couple packs myself but alas, I don't know of anything that uses them, not PETs anyway; I think you're thinking of 2114s, 1Kx4. There were 4 versions of the static RAM PETs: (6316 ROMs equivalent to 2316B) 320008: 6540 ROM, 6550 RAM & VRAM 320081: 6316 ROM, 6550 RAM & VRAM 320132: 6540 ROM, 2114 RAM & VRAM 320137: 6316 ROM, 2114 RAM & VRAM The Dynamic RAM PETs used 2114/6114s for VRAM. ROMS used include 2316/6316, 2332, 2364/6364. RAMS used include 5298, 4108, 4116 Parallel disk drives used 2114s. mike ----------Original Message----------- <snip> <snip>
