Hi all,
I managed to pick over some more Acorn hardware that was awaiting disposal at a
school yesterday and today. I only had about an hour to look over everything,
and there were well over 100 machines piled into a room and cupboard, so as you
can imagine it was a little frantic to sort out the good stuff. (case screws
flying everywhere as I was pulling useful ROMs from stacks of dead machines :-)
Came away with the following:
Two Master Compacts, plus a third system unit for spares use.
Two ICL-built BBC B's. (serial #'s 36xx and 38xx I think)
Two standard Master 128's
BBC B with a Watford DDB3 module plugged into socket for IC78
BBC B with a 3.5" floppy drive + bootable print server disk
BBC B with Aries B20 / B12 boards installed
Master 128 with a Cox 630B genlock card
Two Master Turbo machines
Music 5000 synthesizer unit
Acorn A3010
Acorn A310
A310 "Computer Concepts Scanner Interface" board
A310 Nexus interface board
A310 video digitiser board (Watford)
Around 30 spare Econet modules for Master / A3xx machines
Econet kit (clock box etc) still boxed
Aries B20 / B12 board
Aries B32 / B12 board
6502 coprocessor board
Four 486 DX4/100 processor boards on a small backplane (RiscPC?)
Cub monitor (my only previous example caught fire!)
Acorn RGB monitor w/SCART connection
Numerous floppy drives, video leads, Econet connection boxes, spare
keyboards, spare PSUs, ROMs etc.
Various manuals - not dug into these yet.
Numonics 2206 graphics tablet still in its box
Questions:
Three of the BBC B machines have an IC/module plugged into one of the ROM
sockets with a label saying "RAM". The modules are twice the height of a normal
IC and have a red and black wire coming out of them. The red wire is soldered
to the system board; the black wire has an IC leg clip at the end of it. Any
ideas what these are?
What does that Watford DDB3 module do?
Details on the A310 cards would be nice - specs of the video digitiser, what
scanner plugs into the scanner card (it has an 8 pin min-DIN, a 20 pin
connector, and what appears to be power output), and what the hell a Nexus card
is / does...
Information on the genlock card in the Master would be useful.
ROMs / software / whatever for the Music 5000 unit could come in handy! I
only have the unit itself.
*Any* info on the Numonics tablet would be great. It appears to be complete
(minus manuals - grr!) and supposedly works, but I don't even know what it
plugs into and I don't have any driver software for it. (I'm not even sure how
old it is :)
Pretty much everything seems to be healthy; one of the ICL B's needs the chips
reseating I think and the other one has a track / joint fault in the PSU but
otherwise is OK. The Master with the genlock is dead so I'm hoping the genlock
card has survived! Fills in a few gaps in the collection anyway.
Quick pics of the room as found are at: www.moosenet.demon.co.uk/temp/bbc
cheers
Jules
