Exidy Sorcerer II with S-100 Expansion Unit

Postby DutchAcorn » Sun Dec 31, 2017 5:22 pm

Just had to get this: an Exidy Sorcerer II with some nice expansions:

An S-100 expansion unit:

Vista S-100 floppy interface and two 48TPI full-hight single sided floppy drives:

A hacked-up EPROM cassette, converted to a RAM and IO module

And a Basic Pac.

Status:
- The Sorcerer itself works and the RAM module seems to work (it reports a higher top when inserted).
- One of the drives works.
- The Basic Pac has two dead roms (of the four).
- The S-100 unit: I don't know yet if that works.
- The other floppy unit I suspected that the PSU was faulty so I attached a known good PSU. Resulting in a smoking PCB :shock: One or two 74 chips seem fried.

About the floppy drive: I am looking for the address to call from the monitor to access the drive. I'm sure I saw it somewhere but I can't find it now...

I'll update the thread if I can report progress...

Thanks!
Paul

Found it: its D900. :D So the disk system is fired up by issuing the command "GO D900" from the monitor. The few disks I tried so far worked. It is fun to see Pirate Adventure run on the Sorcerer:

DIL 14 sockets and a 74LS20 + 74LS74 are on order to see if those bring back life to the disk drive...
