OK, The M8108 is in *really* bad shape. As I said, it's split along the card fingers, which means that just about every line going to the bus is broken. It also has a few chips that have been shattered, both along the break and elsewhere on the board. I, for one, don't have the skill to fix it. > >It is possible to run an 11/45 without the MMU, but in that case you need > >a System Address Jumper (M8116 IIRC) that goes in place of one of the 2 > >MMU modules, the other MMU slot being empty. > > Mine has a printed label across the top of the box labelling the slots, > which says, on the slot containing the M8107, "If KT11C option [i.e. the > MMU] not present, use M8116 S J B in this slot." Is the M8116 a simple jumper (a la grant continuity card)? I think that's probably the best move to kludge one of those together, if it's simple enough.

If you have it, I'd also be interested (probably moreso) in the M8116. Thanks, Michael

As soon as I can get roud the back of the 11, anyway :-) Meanwhile I'll just keep it running on the 11/23. > The root password is "root".

Update to RT-11v2 docs online

by af-list＠wfi-inc.com

Hi all, Per requests, and to satisfy my own curiosity, I've posted PDF files of the RT-11 system reference manual alongside the tiff images. These contain the images with the text underneath (i.e. you actually view scans of the original manual but it's fully searchable). A little bigger than the straigt tiff images, but it's nice to be able to execute a find... I tried to do an OCR only version of it, which *looked* very nice. The problem was that processing an old manual, on yellowing paper, well, it wasn't too accurate when dealing with punctuation. Which kind of blew any chance of a hands-free OCR, since it was turning colons into t's and so on. After a few hours of hand-correcting through chapter 3, I gave up. Any other suggestions are welcome, thanks to all the good feedback so far... Cheers, Aaron Oh yeah, it's available at www.retrobytes.org

The normal boot sequence for V7 is to hardware boot the drive, which get the @ prompt, then type 'boot' which runs the 'boot' program, which has a ':' prompt, then specify the drive, partition, and kernel file: @boot boot :rl(0,0)unix Most systems then come up single-user, and you need to type CTRL-Z or CTRL-D to continue multi-user. That might involve also typing in the date/time, and often it's all in uppercase until the right tty driver is running. Lots of systems also do an icheck on the disks before actually starting -- this takes a while. In case you didn't know, to stop it you do # kill -1 1 which kills init and returns to single-user level; then you type # sync a couple of times to flush the disk buffers from memory to disk, and then you can halt it safely. What I want to know is, does that version respond to 'boot' and does it do the disk checks? ------------------------- Ok, it's doesn't boot from the pack so I need a RT-11 to act as primary boot to acess the device at some higher level. My 11/73 does know DL boot though. If I try to boot directly it says non-bootable. Invalid boot block I'd guess. Once I'm at the boot @ (looks just like odt!) either @unix or @boot boot :rl(0,0)unix Also works. I also have the advantage that I have RT-11 for my systems and if that runs it's a good head start as you know the hardware works. <It probably isn't memory, then. It's probably down to something (maybe a <driver) that checks for something like the presence of a register, finds i <on my 11/73, and makes an erroneous assumption. V7 predates the 11/73 by <quite a way, so that wouldn't be too surprising. The way I'm using it the assumption is that it's minimally 11/34 or better. Keep in mind the primary IO, DLV11, RL02 are all direct equivalent to the 11/34 and other unibus boards to the register level. Since it runs I must be doing something right. Allison

Cromemco S-100 system. (Was: HUGE additions this last week!)

by netsurfer_x1＠hotmail.com

>Cromemco? (sp) S-100 system with manuals and software - 4 floppy >drives. I >know nothing about this unit other than it's heavy. It sounds like the system you have acquired is a Cromemco System 3. This (if I'm right) was the high-end model of Cromemco's original S-100 systems. It can run either the CP/M or C-DOS OS.This machine, as you've already found out, is quite heavy because the outer casing is 1/8" (!) thick! This thing could withstand a nuclear blast. ____________________________________________________________ David Vohs, Digital Archaeologist & Computer Historian.

HUGE additions this last week!

by dylanb＠sympatico.ca

Outside of the DEC warehouse stuff onroute I brought my uncle and aunt down with a 24' truck to the US to a prior DEC FE home and here is what was loaded up: DEC PDP -------------- 3 boxes of Straight PDP-8 manuals: maintenance, user, software and hardware, engineering, etc. a few "System Modules Books" Boxes of DECsystem 10 manuals many boxes of DEC manuals, prints, and paper tape software (really cool) Tri-data "File Cart" for the PDP-8 with 50 carts, boards, software , etc... TU56 tape drive parts and Astrotype DECtape units 60 trays of PDP-8, PDP-11 paper tape software 2 large boxes filled with DECTapes from PDP-8 and PDP-8 PDP-11 M8049 - many of them!!!!! :-) :-) :-) DRV-11J approx. 20 of them , probably more. TU45s PDP-11/05s PDP-11/03s PDP-11/35s PDP-11/40s RK07s TE16s Core memory systems (ME11, MM11, etc) RX02s AT least a hundred boxes of manuals Table top TU58 6 Decwriters S-100 --------- Altair 8800 , serial #80, all original MITS boards (15 boards), mostly rev 0, 6 4K RAM boards, 1 CPU, dual floppy controller (2 boards), PROM board, display board? serial/rs232 board, and others I can't identify yet. It came with 3 boxes of Manals, many early newsletters, engineering drawings, etc... and software from MITS. Dual Floppy 8" disk system. Amazingly, the 8800 is in mint condition, unmarked. I never really got into the 8800 hardware back then so I have no idea what some of the boards are... Cromemco? (sp) S-100 system with manuals and software - 4 floppy drives. I know nothing about this unit other than it's heavy. Victor/Vector? Graphics S-100 computer with dual external 5 1/4" floppies, books, etc.. I can't remember the manufacturer name but this board was used with an extender on an S100 system and has all the flip switches and lights to control the micro like an Altair 8800. It came with manuals, etc... HP ---- HP 1000 engineering, user, etc.. manuals HP 21MX system with papertape, mag tape, manuals, drawings, etc... Varian : (Al?) ------------------- Varian 620 user manuals and some others (about 7). Special thanks to Kevin Stumpf for finding emergency storage space. This load took up 400 FT^2. over 300 boxes of manuals, software and *many* PDP-11 unibus boards and 9 cabinets. There is still a few hundred boxes of manuals for old IBM, Burroughs prototype material left there for future pick up. A lot of hidden stuff in the load yet as we had *no* time to browse! This load was *very* difficult as it was located in a 2 story house with basement and garage :-( john PDP-8 and other rare mini computers http://www.pdp8.com
