Somebody (I forget who) was asking for information on the Exidy Sorcerer. I've
found the manuals, and will give a little useful info below.

Memory :
There are 2 rows of DRAM chips on the main PCB. Supported configurations are ;
2 rows of 4K chips (8K total)
Front row (only) 16K chips (16K)
2 rows of 16K chips (32K)
There are 2 jumpers at the front edge of the board (column 11). The front jumper
is fitted if there are 2 rows of RAMs in the system. The rear one is fitted for
16K rams, removed for 4K rams.

Serial cable :
This was a 'hydra' cable with a DB25 to fit the sorcerer, 8 jack/phone plugs
for the cassette recorders and a DB25 serial connector. I'll try to give the
wirelist

I seem to remeber that something was asked about the PSU. According to my
manual, the PSU was mostly on the main board, and used 3 off 3-terminal
regulators for the +5V, +12V and -5V lines. If these are present, then the
external (to the PCB) part of the PSU is simply a mains transformer giving 16V
C/T and (probably) 16V). But if you don't have these regulators, let me know,
and I'll try to figure out what is going on.
