I had that box at work last week, where the chips in it were older than some of the programmers. * Intel 8080 * 5 8212 8-bit buffers (most needed to create the "system controller" as the 8080 used the 8 data pins for the half the address -- it presented the address which had to be latched, THEN set the data pins for I/O). * 8 2102 static RAM (1kB) * 4 1702 UV EPROM (1kB) * 8224 clock chip And the 8080 series reference manual. I added an 8228 system controller, a UART chip, a 20-key decoder, a 2-digit LED controller, and some more efficient memory (some 4-bitx1k static RAM and an 8bitx1k UV EPROM). An S-100 wire-wrap board. I hand assembled a monitor program with, as I recall, 0..F, High, Low, Store, Go functions for the keyboard/display. -- Wulfraed Dennis Lee Bieber AF6VN wlfraed@ix.netcom.com HTTP://wlfraed.home.netcom.com/
