  Looking for Help with Tandon 602S by adrian okeeffe - 01/08/2017 22:36
I am a vintage computer collector and recently acquired a strange machine that seems to be hacked together from a machine from Yugoslavia , an apple ii, what i think is tandon 602S 5mb hard drive, with the controller board and an interface to the apple II.A Diy powersupply, 12' onboard monitor and analog board, 5.25' floppy drive. I have made a video log of my findings with this machine.

At present I am trying to get the motherboard working. When it is working I will be rebuilding the machine.

The tandon drive is the big question as I have no idea about these drives or how to acess it.

Here is a link to the first part of this 9 part video log.. so far.

Please excuse my 'colorful' irish language.

cheers

  Tandon 602s 603s SASI by Bill Degnan - 01/08/2017 22:41
These drives are used in the Tandy 5mb drive and the Commodore D9060. The Commodore is a SASI drive. I wrote a post about how to replace the Tandon 602S with an ST-225 drive, here.

I suggest you check the caps of the drive external drive controller using an ESR meter, and see if you can test the drive in an IBM PC or something easier to work on, to see if you have a good drive.

Good Luck!
