Comments |
The Micro-Professor I was intended as a teaching aid to learn the principles of low-level microprocessor programming and was thus aimed mainly at educational establishments. Its other use was that programs developed on the MPF-1 could be transferred to EPROM for permanent storage and the device then used as an embedded controller. |
