Because of age and having never been opened, this unit is being sold AS IS. No guarantees of functionality
.
The MPF-I, specifically designed to teach the fundamentals of
machine code and assembly language
, is a simple and easy to use
t
raining system
for the Zilog Z-80
mi
croprocessor.
The MPF-I does not look like a typical
microcomputer
It is enclosed in a
v
acuum-formed
plastic book case often used to store a copy of a language textbook, two audio cassettes, and a training manual. When closed, the MPF-I can be placed on a bookshelf for easy storage and looks just like a book or a file. This form factor made the computer more appealing to the buyers, since it could be stored away with ease, and it could blend in with the office or home.
Programs are entered into the MPF-I using
Z-80  machine code
in hexadecimal format. The MPF-I
monitor program
displays both an address and data stored at that address simultaneously using a seven-segment display. There is a spare DIP socket for adding additional ROM
or RAM
to the MPF-I. There are also two3.5 mm audio jacks
on the top right of the computer, these are to communicate with the audio cassettes that are used to store programs and code typed into the machine. One is used to read the drive and the other is used to write data; on a conventional audio
c
assette deck
the wires would be connected to the headphone and microphone ports.
This type of data storage is similar to that of a Radio Shack TRS-80
or the Sinclair ZX-81, which similarly used audio cassettes to store programs the user typed, as well as commercial programs and games the user could buy.
