2 Scrambled PERQs - Going, ... Going, . Help!
I have two PERQs for disposal, a PERQ-1 and a PERQ-2, here in the UK. I
would like to get some data off them before disposal, but am unable to do
this on my own as both machines are somewhat 'scrambled'. I am in contact
with half a dozen PERQ owners, who have helped with copious advice, and to
whom the machines will be going once I have finished with them. The purpose
of this posting is twofold. Is there anyone who can make me replacement boot
floppies (I have blank discs onto which copies can be made)? Is there anyone
who has successfully archived data from a PERQ to a PC who can speed up the
rather tedious process of writing RS232 communications software that I have
This is an update on a posting I placed on the alt.sys.perq newsgroup
I am officially chairman of the Mil-DAP (Military version, Distributed Array
Processor) Resurrection Working Party. These two machines were donated to
the CCS (Computer Conservation Society) to help in the attempt to resurrect
the Mil-DAP. We have succeeded in bringing together the complete set of
hardware for the Mil-DAP itself and its PERQ-2 host computer. The DAP and
host PERQ have been handed over to The Science Museum, South Kensington,
London. The equipment will go to the Science Museum outstation at Wroughton,
The Science Museum does not want our two remaining PERQs, as they are not
actually a part of the Mil-DAP itself. The PERQ-1 is thought to contain some
DAP-specific software, which we intend to copy off onto floppy discs. Copies
will then be sent to the Science Museum. After that, we have no further use
for the PERQs and we have nowhere to keep them. I would have been unhappy
(euphemism!) to see them chucked in the bin. From contacts made thorough
alt.sys.perq, I now have homes for the two machines, but I still have a duty
to archive the data on them before I can release them.
The PERQ-1 is thought to contain some DAP-specific software, which we intend
to copy off onto floppy discs (and, if possible, archive onto CD). This is
proving to be more difficult than we expected; any advice would be
appreciated! Specifically, does anyone have precisely the right software to
build boot floppies for either machine so that the hard discs can be fixed?
The states of the two machines are:
The PERQ-1 is the machine that might have some DAP software on it. I am
effectively in the 'forgotten password' situation (except that I never knew
the username or password and have tried most of the usual combinations).
This is a PERQ-1 T1 with 4k Control Store, portrait monitor and no tablet.
(No, we haven't lost the tablet; it was not there when we picked up the
machine! We have now found a possible replacement.) The machine is running
POS; the top line of the screen reads: "LogIn version 3.10 POS G.666
a-boot". The machine boots up from its 'rigid disc' and gets to the
date/time and user/password prompts. After taking advice, I am going to
attempt to archive the entire disk at block level before attempting to
change things to give me access at file level.
The PERQ-2 is a machine that I hoped to use for copying floppy discs, if
nothing more. I appear to have damaged the disc, possibly (probably?) by
doing a 'Bye Off' instead of just a 'Bye' or 'Bye Wait'. If this is what is
wrong, then I have only myself to blame! Whatever, it now only boot up to
Diagnostic 157 (Disc Failure) when supplied with its boot disc. Until
recently, the machine booted up correctly when supplied with its Boot
Floppy; though it has always stopped at Diagnostic 014 (Could not Boot from
Either Disc) when attempting to boot from the hard disc alone. This is a
PERQ-2 T2 (feature no. = F2361/06, build control serial no. = T2 1619) with
landscape monitor and tablet.
If there is a friendly PERQ owner out there somewhere with the appropriate
boot floppy or engineering tools could you help, please? If so, please reply
to this posting or get in contact at the address below. I have a stock of
8-inch floppies, donated by CCS members, which I can post out to anyone able
to make me the necessary copies.
