The CPU is an RCA 1802, there's a CDP1852 which is a parallel I/O port IC,
RAM is a pair of 2114's, and a 24-pin IC which has a sticker on top saying
(unhelpfully) "IC-584" (but I expect it's ROM).
Finally we have a 22 pin IC labeled "SC-01-A" - Google tells me that's the
actual speech synthesizer IC. The remaining ICs on the board are all
simple logic (74xx etc.)
I found some evidence that the boards were advertised to the hobbyist
market in Byte and the like back in the day, so it's possible that what
I've got is exactly what the owner received; there never was any case and such.
