Hi all,
I've got an old Teac 3.5" drive (in 5.25" mount) with jumpers set as
Drive 1 that I want to install in my TRS-80 Model 4P. Tried to tackle
installing it today, but was unsuccessful. Supposedly the TRS-80
Model 1, 3, and 4 machines will read / write to older 3.5" drives
with jumpered drive select. The 4P's drive cable is card edge only,
so tried using a PC drive cable hooking up the original 5.25 drive
and 3.5 drive using both the cable's end and middle jacks. The 4P
wouldn't recognize either drive in any position.
Anyone know what I'm doing wrong? Maybe it's due to the wire twist
found on PC floppy cables? I'm about at my wits end trying to find a
way to transfer TRS-80 DSK files from PC to 4P.
Yes, it is due to the twist in the cable. That is a PC invention. I
suspect if you wire both of your drives to drive 1 it will work out OK.
