/Mon Jan 23 19:11:42 CST 2006/ while back I posted a WTB for some NSC 800 CPU chips and didn't turn up anyone having any for sale. Calls to the usual surplus places came up empty. I did finally manage to snag a bunch of these--more than I need. These are the 3 MHz ceramic 40 pin DIP packages with a date code in late 1986. Supposedly NOS (they certainly don't appear to be pulls). In case you're not familiar with these, they're basically CMOS Z80 CPUs with 8085 timings. They have the same half-interrupt pins that the 8085 does, but NMI traps to 0066H and there's no RIM or SIM. Interface signals are prety much 8085-compatible with the 8085-style multipexed data/address lines. These are NOT pin-compatible with either the 8085 or the Z80, but my need for them is to replace an 8085 with the assistance of a little glue (mostly flipping a few signals). You can find the data sheet on the web at http://www.alldatasheet.com/datasheet-pdf/pdf/NSC/NSC800.html. At any rate, I've got about 15 of these to spare and will part with them for $2 each+postage I'll give preference to those buying more than one. Cheers, Chuck
