The RCA 1800 Microtutor was used to educate engineers and others on how to program microprocessors. Manufactured in 1976, the unit is fully self-contained with the exception of the 9-volt power converter that plugs into the back of the unit. The user is able to see the soldering done on the underside of the main board because of the clear plexiglass bottom. There are 3 slots in the back of the computer labeled M,P,E. The M, standing for memory, allows the insertion of a card containing 256 bytes of memory. The P slot, for processor, allows the insertion of a processor, which in this case, is the RCA CDP1801. The third slot labaled E, is for the expansion and allows users to custom create cards for controlling other devices.

Microtutor is an 8-bit computer powered by the RCA CDP1801 microprocessor. It's made up of 2 plug-in IC's, the control IC and the register IC, both of which are mounted on the same plug-in card. There are four control switches and eight data switches. The Microtutor has a RAM of 256 bytes.
