Photos of RCA COSMAC Microkit with 1801 card.
Note the chip date of the TC 1085 on the processor card, which is the
earlier version of the CDP 1801 (Microtutor), has a silk screen date of
late 1974.

Does anyone have a COSMAC Microkit user manual? I have downloaded the docs
for the COSMAC chip from Bitsavers, but there is no reference to the
earlier Microkit in this doc.
The only printed reference to the Microkit I have is

df
EDN Microprocessor Design Series Volume II 1975
This appears to be a supplement publication to the EDN Journal (?)
I can use the Microtutor manual at least to get started.
