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.)
Votrax speech synth

find in my local book store's pile of scrap electronics heading for
recycling - a Netronics Phoneme speech synthesizer. IC dates all around
mid-1982.
What are the main ICs on the board (basically anything other than TTL, 4000
series CMOS or common op-amps)? 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.
This will fill in some blanks:
