Nice to see such interest in the BBC - I keep forgetting it's not very common outside of the UK. I've got a couple of spare BBC Masters up for swaps if anyone's interested? I'm looking for Xerox technical manuals (see list), software, even hardware if the shipping's not too prohibitive :-) The machines I've got don't have any documentation or software (although you can still buy new Master manuals from 8BS and download whatever you need could probably do with a makeover. I did a first pass at cleaning them up when I got them but haven't spent as much time on them as I could ("my" Beeb gets most of the attention!). If you're not familiar with the Master, it was the follow-on from the Model B and Model B+. Basically the same hardware as the B/B+ with 128K RAM (paged) and a 6510 in place of the 6502, housed in a bigger case with "enhanced" keyboard (ie a keypad) and a couple of cartridge sockets. All the I/O ports of the B/B+ were retained (disk, RS423, 1MMz Bus, "Tube" etc), and they added a couple of popular application ROMs (View and ViewSheet) as well as the ADFS and DFS filing system ROMs as standard (you had to buy these yourself on the earlier B/B+ machines). For us hackers they added a terminal emulator, upgraded BASIC (BASIC IV) and upgraded assembler, very nice! Anyhow, if you're interested in swapping, I'm looking for the following Xerox manuals: XDE 12.0 Users Guide (or later) Mesa Language Manual (11.0 or later) Mesa Programmers Manual ViewPoint Programmers Manual Pilot Programmers Manual Basic Workstation Programmers Manual Services Programmers Manuals Either hardcopy or original VP softcopy is fine :-) If you've got something I've missed off the list I might be interested, drop me a line.
