However, it is written in PAGE8, which is another assembler for the PDP-8. I also happen to have PAGE8, so I should make all of that available, when I have time and access to my PDP8 systems. I also have the VISTA manual, but I think I might only have it in paper form, so I guess I should try and scan that at some point as well... And yes, I'll try to upload my EMACS-clone as well. Just give me time... :-) Johnny

Four Phase systems IV/90 info needed

by g-wright＠att.net

I have one of these that I would like to get going or at least see how far i can get. I don't see much out there except Al's site. Witch has limited info. Does anyone know of? hardware and trouble shooting? manuals and what type of? terminal interface they used.? I found this is a Horse arena upside down. Jerry

VME catalogs

by wdonzelli＠gmail.com

I have a bunch (about 13 pounds) of catalogs and datasheets for VME products from various manufacturers, plus a directory or two. Any interest in the pile for $5 plus shipping (media rate - cheap)? Contact me off list. -- Will

MASSBUS was on the decline anyway. And if you were going with mP systems, you could hook up massbuses to several CPUs, meaning you'd get a lot of them in the end anyway. Or actually, this was probably when MASSBUS was still very much hip. Well, mP still meant you could get lots of massbuses on the system, and RSX-11M+ supported mixed massbus configurations anyway, so you could get away with fewer massbuses. The other option would have been to remove the 4 slot Unibus at the back of the CPU, and just have the single SPC slot, and the out. > The CPU board set was essentially the same, slot for slot.

I'll have to check it out - I've been hacking HD44780 and T6963 and SED<mumble> displays for years for LCDproc. It's especially fun to pull on from some dead bit of technical kit and put the LCD back in service. I've done that with a $8 front panel from a satellite TV converter box (LEDs, buttons and 2x40 HD44780 LCD) among others. -ethan

Slightly OT: Sun Ultra 5 Keyboard

by robert.jarratt＠ntlworld.com

I was given a Sun Ultra 5 the other day, not really a vintage machine, at least not yet, hence "slightly OT". I don't know anything about these machines but I expect there will be people on this list who do. The machine came without a keyboard or mouse and I think I need at least a keyboard to get it to boot. I believe I may need a type-5 or type-6 keyboard with a mini-DIN connector. I can't find much on eBay. Can anyone tell me where to find such a keyboard? I don't want to spend a lot because Sun is not my thing really, but it would be nice to get it working. Thanks Rob

Each of the two PSUs needs to be sufficiently loaded to work and if either is not happy the system shuts down. So if you arrange to have enough load in slots 7-12 you can put the load board to one side for now. However, the CPU and memory need to be in the first few slots (iirc) and I very much doubt that a DESQA and a TQK70 are enough to keep a PSU happy. If you had a KDA50 in there you'd be fine, I would guess. > Incidentally, anyone know why this machine has two PSUs if > they are not (as I have read somewhere) redundant? I assume that there was not a single PSU around that could supply all 12 slots. There are at least two BA200 series enclosures: the 12 slot one you have and a smaller 6 slot one. I assume that a single power brick is enough for the smaller enclosure and that it was simpler to have two power bricks in the bigger enclosure rather than go off and design a more powerful brick. Remember that when these things were new 180W was chicken feed compared to the more powerful machines of the day (like the VAX 6000 series). Antonio

I should have asked someone I suppose. The PERQs and Cray are in the "Scientific Computing" room in H Block. There's a lot of DEC hardware in there, such as VAX, PDP and the like. I think the TU77 tape drive that I took to BP is in that room, too. -- John Honniball coredump at gifford.co.uk
