RCA had a bit-slice part in one of their 1970s COSMOS

app note in the back, but I've never been able to find that particular
COSMOS databook again, so if it went into production at all it must not
have lasted very long. My recollection is that it was not as fancy as
the Am2901.
I have a 1985 RCA databook titled "High-Reliability Integrated
Circuits" that sounds very similar. The parts listed as part of the
'EPIC' chip set are
- GP001 8-Bit General Processor Unit
- GP501 Emulating Controller
- GP502 Microprogram Sequencer [2910 clone]
- GP503 8-Bit x 8-Bit Multiplier
- GP511 Voltage-Level Converter and Buffer
- GP301 512 x 8-Bit ROM
- GP302 256 x 16-Bit ROM
They list as "planned",
- GP514 Double Address Select Unit
- GP515 Double Register Select Unit
- GP516 Bus Interface Unit
- GP517 Interrupt Control and Timing Unit
The related app notes, all written by one K Karstad, are
- ICAN-7202 An Introduction to the Use of the General-Processor Unit, GP001
- ICAN-7211 Introducing and Applying the 8 x 8 CMOS/SOS Multiplier, GP503
