Subject: Filestore, and Torch Communicator

If the Master-Compact-looking box has two Centronics type ports
at the back marked "FileStore Expansion Bus" but nothing for
Printer or Econet and no floppy drives on the front of the unit
then it's a FileStore E40S or E60S.  All you will find inside is an
early SCSI Winchester disc, probably Rodime, and a power supply.

Unfortunately there is no host adapter as these units connect directly to
the Stacking FileStore E01S, unlike the earlier FileStore E20 which
could be connected either to the 1MHz bus on the FileStore E01 or
a BBC 1MHz bus port because there was a host adapter inside
the box as well.

It is highly likely to have Econet data on it, I would think, since it
can't easily be used for any other application and to format it without
dismantling it you would have to connect it up to an E01S.  You might
be able to connect it to a BBC using a host adapter but even then
I think you would have to use a disc sector editor to read it unless
somebody has a utility to mount the Econet partition.

Best wishes,



Ian

Are there any other ports on it?  The filestore was a standalone
device, no need for a controlling beeb, and had econet, scsi and other
assorrted connectors on the back.   It sounds like you might have an
expansion hard disc for one, if all it's got is a captive SCSI cable..
 Useless on it's own, but if you can't find someone with a filestore
to attach it to, you may be able to hook it up via a scsi adapter
direct to a beeb to recover some of the data..  (It's definitely
always worth finding out what's on such things in caase it's something
unknown or previously considered lost! It's in it's own format, btw,
so would need recovery tools rather than *adfs !)

No, the acorn filesever software for using on a Beeb was for the 6502
co-processor.  What you have is a Torch Z80 second processor.  Fairly
popular in it's day, as i think it was cheaper and more available than
the Acorn one.  It runs CPN (a modified version of CP/M) from ROM -
you should be able to fire it up with, wait for it... *CPN    It will
run most CP/M software out of the box with no problem.  (as long as
the software does bios calls legally, which almost all does as there
was such a vast range of hardware at the time it would be impossible
not to!)


It has a key-lock fitted into the ashtray

That sounds likely - follow the wires, see where they go!

Enjoy!
