Ah... thanks for the extra detail... didn't

multiple versions of the SC/MP.
In the interest of completeness, then, I'll note that the part number of
the original SC/MP was "ISP-8A/500". The SC/MP II was known as both
"ISP-8A/600" and "INS8060"; AFAIK it started as the former and was
changed to the latter, perhaps because they decided that having
punctuation in part numbers wasn't such a hot idea.
Similarly, the National Semiconductor PACE ("Processing And Control
Element", the world's first single-chip 16-bit microprocessor, PMOS,
1974) had the part number "IPC-16A/500", but the later NMOS version
is the "INS8900".
