Don't know if this is "classic" enough, but it might interest some people... https://www.riscosopen.org/news/articles/2012/10/26/risc-os-pi-released-ris… There is a final, complete, stable version of Acorn's classic Archimedes OS now for the Raspberry Pi, making the RPi the cheapest Acorn-compatible there's ever been by a long way. It's based on ROOL's RISC OS 5.19, the latest version of the shared-source fork of RO, based off Pace's version. (That's Pace the satellite-TV/set-top-box/modem company.) RISC OS Ltd is still developing its closed proprietary version based off Acorn's unfinished betas of what was to become RISC OS 4 and still claims that Pace/Castle's version is unauthorised and not legitimately licenced. However, nobody much cares any more. ROL hasn't released a new version in several years and doesn't support modern and recent ARM hardware such as the Iyonix, BeagleBoard, PandaBoard and now Raspberry Pi - it basically just sells (quite expensive) updates of RISC OS 4 for classic Acorn hardware and directly hardware-compatible machines. It rebadged the latest update after 4.39 "RISC OS SIX" just to leapfrog Pace and ROOL's developments of RISC OS 5. -- Liam Proven ?

If legible, such plots could be reconstructed by tracing in Adobe Illustrator. Contemporary sign-makers have tools that can load the Illustrator "legacy" EPS format and convert it to formats used by plotters and vinyl cutters. - John

Hobbyist OpenVMS availability (WAS: Re: Microvax II won't boot, hardware error?)

For any earlier version ask around (also give location). HP has said in the past that they have no problems with hobbyists borrowing media, but they continually reiterate that they would not like to have it posted for public download. There are probably people on here who have it (I have 5.5-something, 7.2 and 7.3) , or you can ask on the OpenVMS Hobbyist fora.

Maybe something is hanging up the Q-bus, or you have failing memory. If you have diagnostics, running a memory test for a while may get you somewhere. Otherwise, I'd look into trying to pinpoint the problem by removing memory modules and see if the system becomes more stable (assuming you have multiple memory cards, of course). -Rick Memory is NOT on the Q-bus, it has it's own dedicated bus on the C-D connector rows (how many slots are memory only in the CD rows depends on the specific backplane.) Possibly you might have a Q-bus board in a memory-only slot, that is certainly something to check. Otherwise, you may have a bad memory card, a bad or dirty slot, or possibly a bad CPU board. Hmm, I've never seen this error, but I think if a peripheral board is bad, it does not cause a machine check, but maybe I've never had the specific error. Can you tell what the physical address was? or, at this point, might virtual=physical? If so, is 7FF3xxxx in the Q-bus I/O space? Jon

Wanted: DEC Rxxx module photos

by v.slyngstad＠frontier.com

Hi, Today I have finished documenting the Rxxx "flipchip" modules in my possession. These are the modules from which most straight-8 and PDP-8/S gear was constructed: http://www.so-much-stuff.com/pdp8/flipchip/flipchip.php http://www.so-much-stuff.com/pdp8/flipchip/Rxxx.htm The Rxxx modules are a smallish subset of the larger DEC modules space: http://www.so-much-stuff.com/pdp8/flipchip/modules.htm Unfortunately, there are several Rxxx modules for which I have neither example or picture: Module Versions Description R211 K* L* MB, PC, MA, (PDP8) R212 A* J* MQ (PDP8), 2 FFs, SR, SL, Read-in, Clear R220 F* L* 3-Bit SR, Parallel Read-in, Diodes out for detecting all 0s in R111 node R284 A* Quadraflop, PDP8, 4 stable states R450 D* E* Clock for use with TTY, first pulse comes 1/2 period late R451 E* Teletype Clock, for faster teletype think R450 R601 B* F* H* Pulse Amplifier, 6 DCD Gates, 100 or 400 ns pulses R613 B* R603 that cannot be triggered from output, with 5 mA loads R650 E* Bus Driver, 2 circuits, 2 Inputs & Node (* just means I don't have a board drawing for it yet) There are also some more exotic modules for which I lack even a schematic: R012, R1110, R1130, R152, R200, R406, R407, R408, R623 and I don't expect to be able to locate or do much about those. Anyway, what I'm looking for is some help with the former list. If anyone has examples of these, would it be possible to photograph the component and solder sides with decent resolution and forward the photos to me? (You are welcome to forward the whole module, but I don't expect that :-).) The version information just refers to versions that I have schematics for. Any version you have is fine. I am particularly interested in the R2xx, as those are key modules for the straight-8. Thanks in advance for any help anyone can provide. (Meanwhile, I'll start drawing Sxxx modules.)

Colossal cave map

by djg＠pdp8online.com

Does anyone have the data set used to generate a colossal cave map like this one? It would make a nice demo for my plotter. The site owner doesn't. http://aquaporin4.com/
