Tandy Model 4p needs new floppydrives

[fritzeflink]

Hi,
I just got a M4p with the original 40tr SSDD drives and I would like to replace them with teac FD-55F 80tr. drives. I love the TRS-80 clones from germany but never had a TRS computer or this lovely M4p.
As I see there are pins missing in the plug of the cable I need some help with connectinmg the teac drives. They are patched with a 40/80 tr. switch so booting from the old 40tr. floppydisks will be possible.

30 Years ago I got an 'expanded' M4p but today I do not know what was done with it.

You will need to find or make a straight-through cable with all the pins. Drive select will be through the jumpers on the drives. The original drives had all drive select pins connected, and the cable handled the drive select.

You can't use an IBM PC floppy cable with the twist.

Thanks for the info, now there are:

A: Teac FD-55B (360k)
B: Teac FD-55F 03U (40/80).
