The connection of the PC-34 cable with the Shugart-50 ribbon cable is made using two clamp bridges and a variety of screw bridges. The following illustration shows only the even signals. All odd signals are ground; DC ground (GND).
In principle, the signal TG43 on line 2 (TRACK GREATER 43, WRITE CURRENT LOW) also appears on the Mitsubishi M2896-63. The drive is already so new that it also allows internal support via jumper (SI or SE) and the external line no. 2 is not needed. But this is not true for all 8 inch drives.
Other drives with an internal TG43 jumper are the Tandon 848-1E and -2E (1983) - please do not confuse it with the earlier Tandon 848-1 or 2 (1982) - and the Shugart 860.
With the help of the terminal blocks and the screw bridges, the floppy can be connected both as drive A: or B :. For A: PC-34 (10) must be connected to Shugart-50 (18), for B: line 16 to 18. Analog is for DS1.
If you want to use two drives, then you have to put on the 34p floppy cable a so-called branch connector. Previously, the tape drives were connected to the floppy controller in this way.
The Mitsubishi M2896-63 is a outstanding 8 inch floppy disk because of its variety of switch / jumper settings, especially the jumper for the internal TG43 signal. The floppy does not require an AC 220V / 110V line for the motor and the power plug is still easy to buy at Farnell or TME.
In contrast to the Shugart 860 it is only to mention that the engine is always in operation, as soon as a disk is inserted and locked. The Shugart 860, on the other hand, starts the engine only when it is accessed. Therefore, I find the Shugart 860 a little bit better. Just awesome to look at is the Mitsubishi locking mechanism.
