More Amiga 2000 help/info needed.

by netsurfer_x1＠fastmailbox.net

Well, thanks to everyone for their help on my A2000. Now that I've cleaned it out (you wouldn't believe how much dust there was inside!). It seems as though this machine is having some more problems. It now shows the self test screen colors in the following sequence: dark grey-light grey-yellow. Can somebody *please* help me out! I don't want to have to confine this machine to the trashpile! Also, if someone can direct me to a PDF version of the manual, I'd be very appreciative!

manuals in pdf (resolution, compression)

by aek＠spies.com

Using tiffcp to change the compression from lzw to g4 more than doubles the size to 1.6 MB. That's for a single page. -- Something is really broken with what you are doing. A normal 400dpi G4 compressed text page should be 50 - 100k. Scanning though the sizes of a manual I just scanned, it's closer to 15 - 50k / page.

character codes, was RE: Really stupid PDP assembler question

by melamy＠earthlink.net

another reason, the CDC 6400 (circa 1960s) COMPASS assembly language instruction set made sense "opcode" wise to express it in octal. They had 15 bit, 30 bit, and 60 bit instructions with a 60 bit bus. best regards, Steve Thatcher (who does still write in assembler...and most everything else)

Philips P2000C disks

by julesrichardsonuk＠yahoo.co.uk

I think a couple of people expressed an interest in boot disks for the Philips P2000C a few weeks ago. I only just got into the museum stores today to see what we have. Reading off disk labels (I know *nothing* about these machines!)... Specific (original) 2000C floppies I found: Copower disk CP/M Copower disk MSDOS 2.11 Wordstar 3.3 Calcstar 1.45 CP/M 2.2 ABASIC P 2509-L / TTY P 2526-L Grafox Dataplot+ P2000C Maintenance Program MN11 Also the following copies (I have no idea how a P2012C differs from a P2000C!): P2012C CP/M P2012C MSDOS Utilities P2012 Cardbox P2012-16 CP/M boot disk for MSDOS (P2000C mode) <non-IBM MSDOS s/w> P2012-16 CP/M boot disk for MSDOS (PC mode) <IBM PC software> P2012-16 MSDOS (P2000C mode) System disk <non-IBM PC software> P2012-16 MSDOS (PC mode) System disk <IBM PC software> P2012-16 P2012C CP/M MS-boot, MS-util, R/disk copy of master disk P2012-16 P2012C MSDOS utilities copy of master disk P2012-16 Copower disk CP/M copy of master disk P2012-16 Copower disk MSDOS 2.11 copy of master disk P2012-16 CP/M 2.2, Wordstar 3.3, Calcstar 1.45 copy of master disk P2012-16 ABASIC P 2509-L TTY P 2526-L copy of master disk P2012-16 Grafox Dataplot+ copy of master disk P2012-16 Maintenance program MN11 copy of master disk P2012-16 Test pattern disk for use with MN11 maintenance software A lot of those copied P2012 disks sound suspiciously like direct copies of the P2000C originals. What's the difference between the machines? What's the easiest way of copying these? I can put a 360K 5.25" drive in my desktop PC and run off some disk images, assuming they aren't some oddball format which the PC controller can't cope with. What's the best software to use? (I can boot MSDOS, Linux or Win 2k on the desktop) No idea if data is intact on the disks of course, but they're all boxed and look to be dust free. I also found the following P2000C documentation, although scanning is probably out of the question (happy to look stuff up though!): P2000C System reference and service manual set CP/M reference manual MSDOS user guide Copower board reference manual Calcstar manual Wordstar manuals 1 and 2 Disk BASIC reference manual P2000C operator manual Dataplot+ user and reference manual Advanced BASIC interpreter operator manual TTY user guide CP/M user guide P2000C software catalogue cheers, Jules

At least it can format blank media. True more or less, but sells the Rainbow a bit short. It has both Z-80 and 8088 (arguably 16-bit?) processors, runs CP/M-80 and CP/M-86 as well as the DOS you described (and VENIX? Not sure that that is still resurrectable). The "Rainbow" was (according to at least some of their literature) intended to be a bridge between the 8-bit and the 16-bit software worlds. -- - Mark 210-522-6025, page 888-733-0967

DEC & HP available - a trip to an infrequented collecting spot in stlouis

by jwest＠classiccmp.org

I had an opportunity to visit my absolute favorite spot in St. Louis for old puter stuff. It's definitely not open to the public and the opportunity came to get in today so I went. I found some stuff that may well be of listmember interest. First. Pallets and Pallets of DEC disk drives... RD52, RD53, RD54, etc. I even found a case (about 8 drives) that were RD54's that were new or refurbed and STILL SEALED in antistatic bags. There were several mounting trays and rails for these drives, sealed in bags too. There was also some other drives that were RZxx, I don't remember the xx part, and they looked just like RD53's do. Two DEC LA120s (very yellowed) A pallet of IBM selectrics. A really nice microvax cabinet, but it had been stripped of all cards. A bunch of 1/2 mag tapes, 6250bpi , still in original seal. A few HP line printers... don't remember the model... but they are pretty big. Maybe 4 feet tall, about 8 buttons on the top. Looked to be in good condition. Freestanding units built inside a cabinet with wheels. I have seen and sold these before but I'm drawing a blank on the model. I am guessing around 1987 era? This model is known as a tank/workhorse. An odd dec item I've never seen... it was something like TA90Z... I figure it was a tape drive. Pretty huge. But on the front through the cabinet cutout were the buttons I'm familiar with on 14" drives - run, stop, fault, drive ID plug, etc. And in the front was a recess where a removable hand-held keypad unit sat. This hand held unit had like 40 or so buttons on it, almost looked like a diagnostic keypad or something. Odd. There was a nice dec rack with something in it that looked like a disk drive... HSC... something. Didn't get too close of a look. A few HP lowboy cabinets, and some 7980S tape drives. Several microfiche readers that looked in good shape. I spent a lot of time talking to the owner, and sucessfully built a rapport. I'm welcome to come back any time, and they'll let me just walk through. They also agreed to call me when stuff comes in that may be of interest so I can have a looksee before it's torn apart. The "big iron" stuff listed above they will let go very cheap. However, the RDxx drives they know get some amount of money on ebay, so those they will not let go dirt cheap. If anyone is interested in any of this, let me know. They will be moving buildings before too long and want to get rid of as much as possible so they don't have to move as much. That means their motivated to get rid of the heavy stuff cheap. I'm also curious just what that TA90Z thing was. Jay

S-100 stuff found

by waltje＠pdp11.nl

Hi gang, Just returned from a customer in Norway. While cleaning up some issues there (which included doing some *literal* cleaning up; the place's machine room had never seen a cleaning... eeeew !) I bumped into a box with "ohyeah, thats old stuff, just throw it out" kinda stuff. Obviously, I opened it up, and found a couple PDP-8 boards (DP-8 programmable timer) with manuals, and about 14 what looked to be S-100 boards. More checking and some calling last night indeed confirmed these to be S-100 boards: Cromemco 64KZ 64KB RAM board Cromemco PRI printer interface Cromemco 16FDC floppy disk controller Cromemco WDI hard disk interface unknown 32KB STATIC RAM board (qty 2) XCOMM 001785 ? serial interface board? (qty 2) XCOMM 001790 SA1000/ST506 interface (qty 2) unknown TMM416-based RAM board (64K it seems) NNC CPU-Z80-IEEE NNC CPU board (qty 4) If anyone wants there, make me an offer I cannot refuse. Yes, I can bring them to the U.S. next week, if so desired, and ship em >from there.

Macs: Billions and Billions sold

On June 9 John Allain wrote: > > But anybody have any creative ideas on what to do > with two or three Mac Classics that I keep finding. > I can't throw them out, on conscience. At one MacWorld I attended one vendor had taken dozens of Pluses, SE's, SE30's and Classics and built what can only be called a throne out of them, with a Lisa for an ottoman - and ran the Pyro! screensaver on them all, then photographed show-goers sitting on it and handed out the Polaroids. That took dozens of mini-Macs but perhaps you could use the few you have to do something equally silly - run the Energizer Bunny, network version. Hook 'em together with PhoneNet, install the init on them all and the "Start Wabbit" application on one, and let it rip. Bunny marches across one screen, then the next, then the next and around and around. I have the software if you want it. Sort of a deranged kinetic art form... Seth Lewin
