Parts from my old (failed) attempt to build a small computer

_MG_0184

Finally inventoried the parts after years in storage. Lot of chips, though nothing that rare or interesting. Somewhere I have the schematics I designed. Will scan them when I find them. I doubt it really would have worked, and I never got an EPROM programmer working. Very tempted to try to figure out how to reuse some of this building something like N8VEM.

List below the fold.
Large chips
MOS6526R-4 2084 (x2)
8464A-80L 8841 T12 – 64KBIT SRAM?
SCL4581BE 7731 T6 – ALU? (definitely not part of the plan)
ST88936N M2764-2fI PGM 12.5V – EPROM
SARONIX 83 XTAL OSC 1.0.0.0 MHz NCT040C
S/B8412 INS8250N-B – UART
ZILOG Z8400A PS Z80A-CPU 8312 – CPU
