Unfortunately the appointment with Fred Jan to copy disks has changed date.
But still I was very curious about the TRS80 system. I have some 8 inch diskdrives
and floppies in unknown state which came with the TRS80.
- The 801 drive is missing the PCB and it's filtpad (which is used in de TRS now)
...Besides it's an 115V model and can not be used here. Nice for parts.
- The CDC drive which seems to have a different interface.
- The last drive is an 851 which is used in my Xerox 820 II to!
I'd clean the 851 drive, Jumpered it like the ones in the 820. And yes it works in the 820!
According the website from Dave http://www.classiccmp.org/dunfield/img/index.htm
I'd made my own 8 inch setup on an old P75 machine. The 430FX chipset tested to be very useful.
I'd replace the single use dips for a dipswitch version. The settings on
the P75 machine differ from those on the Xerox 820 machine.
This is my 34 to 50 pin convertor. (TG43 not used at the moment)
And the total setup for testing...
Very Very Very curious..... :D:D:D:D:D
