Another version ^
From a technical brochure: (Thanks to Professor Elliot Tanis for this info)
The IME Digicorde is a magnetic disc sequential programmer which
controls the
IME: 86S electronic calculator. It is used where program
length exceeds 32 steps or where more program flexibility is desired.
The Digicorder provides a capacity of up to 3.000 individual steps.
Constant factors can also be entered on to the magnetic disc from
the keyboard of the calculator to be called out at the appropriate
point of a program. The operation of the Dlgicorder is very simple.
Position the master switch on the Digicorde to the "program" mode
and actually perform the problem on the keyboard of the calculator.
When the problem is completed, the master switch is put in the
"compute" mode. To start the program, just toych the
[RC]-key on
the keyboard of the calculator. The Diglcorder automatically locates
the start of your program. Stop codes in the program as well as a
code for looping or finding the beginning of the program automatically
are generated from the keyboard of the Digicorder.
The ease of programming and the versatility and the speed of this system
trtruly make the IME-86 a desk top computer.
