Default SC/MP Kit / Introkit info

There are a few people here who are interested in the SC/MP microprocessor - I've just been alerted to the availability of a cache of SC/MP and in particular 'SC/MP Kit' (as opposed to 'SC/MP Introkit') documents.

The 'SC/MP Kit' and 'SC/MP Introkit' were two SC/MP evaluation PCBs which were available from Nat Semi and in their most basic form consisted of the uP, some RAM, a PROM and a 7414 IC configured as a serial TTY interface through which the user could interact with the system using a terminal.

To either of these systems you could add the same additional set of components, along with a different PROM, to make them into a classic microprocessor trainer with a 20-key hex / command key keypad and a calculator style style 7-segment display.

The 'Introkit' + Display / Keypad kit then became the basis for the Science Of Cambridge MK14, which initially even used the same OS / Monitor.

This cache of documents on the website of 'CuriousMarc' - worth seeking out for all his interesting micro / computer stuff online - mainly concerns the 'SC/MP Kit' rather than the 'Introkit', although one of the documents (which details how to retrofit an SC/MP II to both systems) does have nice PCB layout drawings for both the 'SCMP Kit' and the 'SCMP Introkit'.

The document dealing with the Keypad / Display kit contains the circuit diagram for that portion of the circuit, and since this is the same whether added to the 'SC/MP Kit' or the 'Introkit', it is effectively three quarters of the circuit diagram for the 'Introkit' (when fitted with a display / keypad).

There are also a couple of documents of general SC/MP interest. I've stored local copies as well, in case they disappear from their current location.
