The 11/45 has booted an OS for the first time since I got it. RT11 came right up. Interrupts are working. Awesome :) That's actually very satisfying because the machine was in very rough shape when I got it. After fixing the power supply (which was a new problem, unrelated to the previous interrupt issue I think), I started growing the configuration back to where I wanted it to be in little increments... like adding the BA11K back in (with nothing in it, just the 930). Then putting in the M9312, Then adding in the unibus memory, RL controller, dropping the core out of the picture, etc.... and testing between each small step. It got back to the full config and still interrupts are working. So, unfortunately I'm not sure what actually fixed the problem which is a little unsettling. But it was a big thrill to see the RT11 prompt :) That being said, I am using a borrowed set of cpu boards. Over the next few sessions I plan to start adding my boards back in one at a time and I'm betting some of them won't work so I'll still be looking for help to repair those (and that will also help me understand the machine better). Note that the interrupt problem occured with the same borrowed cpu boards, but now it's gone. Odd. Another oddity reared it's head. The system was very stable with just the RL controller. I then installed an RX02 (M8256) controller (and removed the NPR jumper for that slot). I turned on the system but left the RL02 turned off. The RX02 worked perfectly. Then I turned on the RL02. It powered up ok (no fault) but when I spin it up I got a fault light. It is not the drive, nor is it the pack. If I shut everything down and leave the RX02 drive powered off (but controller still installed), the RL02 will come up fine and not fault. So there is apparently something that the RL controller doesn't like about the RX02 controller? The NPR jumper is removed for the two slots where the RL and RX controllers are, but definitely present in all other slots. I'm also soliciting advice on memory configuration. The processor has 16Kw core in the system chassis. I don't own any MOS/Bipolar. I have two unibus 64Kw memory boards (M7891 I think it is). My plan was to run the system with one 64Kw unibus board, hold the other for spare, and leave the core disconnected. I know I can run RT11 ok in 64kw. But based on requirements for other things like RSTS, etc... am I better off leaving the 16kw of core connected? In other words, for most DEC OS's on the /45 am I going to have trouble with 64kw but not 80kw? If it won't make a difference in what I can run I'll probably just leave the core disconnected. Thoughts? Thanks! Jay West

Simtel Walnut Creek CD-ROM (speaking of ftp archives)

by spectre＠floodgap.com

I was trying to find my Simtel Walnut Creek CD and can't (I have no idea where it went). Does anyone have one of these that they would be willing to copy or make an .iso image of? If a physical copy is easier to manage, I'll gladly cover cost of shipping, media and inconvenience; either way, please contact me off list. -- --------------------------------- personal: http://www.armory.com/~spectre/ --- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- Never underestimate the power of stupid people in large groups. ------------

ASR33 selector magnet driver card

by djg＠pdp8.net

If you are referring to CR1 and CR2 on the plug in card 181821/181823 they both seem to be 1N4383. One I could read the entire part # and the other all except the last digit.

What is far more telling is that I have few doubts that you know exactly what is meant.

Nicolet NICE Z80 Emulator

by doug＠stillhq.com

Hi, I have just found a Nicolet NICE Z80 in-circuit emulator. (I used to use one of there years ago in a previous job) Does anybody have a copy of the users manual for the unit, or a rundown on the available commands? Doug

It is thousands of dollars per month. Uggg... I apologize for my typo. For symmetric Mbps (note M, not G, and lower case b), THAT is what is thousands per month. Jay

Don Maslin/Archiving system software

by dm561＠torfree.net

In all the noise I didn't see any replies or comments re my original post (see below) so can I assume there's no one interested in actually setting up a "who's got what and where" directory somewhere, or that it's not a feasible idea? mike ----------Previous message: I've seen it mentioned, but are there actually any plans to host a master catalogue of old software somewhere where people could just list what they have available, with a search mechanism that could essentially look like bitsavers et al and let you select a brand/model/title but instead of (or in addition to) a direct FTP link return a list of web sites and/or email addresses where it could be found or requested? For example (and I doubt that I'm alone in this): I have a bunch of Cromemco software but not the time or even the inclination to copy and archive it in all its various formats, but if anyone ever wanted a copy of something in a specific format (and knew that I have it) I'd be glad to help out, and I could probably find the time to make a list if there were a place for it and an agreed-upon standard for its format and content. Same thing with documentation; I'm not about to scan all the manuals, tech bulletins, etc., but I could make a list and would be happy to scan a few crucial pages if someone needed some specific info. (Note to Al: I haven't forgotten; still working on your pile). I realize that this doesn't address the issue of actually archiving this stuff and I appreciate the efforts of Al and others to make sure that it doesn't disappear, but I suspect there is a lot of software and information out there that can't be found anywhere on the 'Web just because its owner doesn't have the time or doesn't think it's useful; in fact there's probably a fair bit of stuff that people wouldn't even know existed until they saw it listed somewhere. Granted, there'd be dead links etc. after a while (although I suppose it wouldn't be too difficult to automatically verify them every now and then), but nevertheless I think it would bring a few useful items out of the woodwork... mike

Telmat P1085 (Esprit Supernode) - more bad photos of transputer kit!

by andy＠smokebelch.org

Apologies again for the quality of the photos. So this machine has been kept in a damp basement for a while, and on removing a side panel noticed the PSU has become fairly rusty in places. Should I just try and rem\ove all the rust and vacuum / blast it with compressed air? And same for the backplane and cards etc... http://media.emergency-music.org/telmat/front.jpg http://media.emergency-music.org/telmat/side.jpg http://media.emergency-music.org/telmat/cage.jpg Since the photos are poor included details of some of the ICs (ones I thought may be of relevance): - Backplane takes up to 7 cards, is marked 'Version A 22/10/89' and has 4 x ceramic 80486 sized ICs marked 'NEC RSRE S01 8714K9'. I don't know what these are but suspect they may be soft configurable devices for transputer link routing. - 1 x mass store, with 4 banks of 36 x HM511000P105 http://media.emergency-music.org/telmat/store.jpg - 2 x compute boards, each with 8 mezzanine boards containing an IMST800-G20R and 8 x HM62256LP-8. http://media.emergency-music.org/telmat/cn.jpg (mezzanine) http://media.emergency-music.org/telmat/cn2.jpg - 1 x P1085 Controller, with amongst other things a Z8053006PSC, ICM7170 RTC, AM2864BDC, 16 x HM62256LP-8, Li battery etc. http://media.emergency-music.org/telmat/controller.jpg >From Googling it looks like this was the target hardware for the Paros system, and so would be booted via a PC. I'm not sure whether the controller card is some kind of minimal host or just responsible for configuring link routing. The case also has provision for disk and tape drives, which may well have been for the future and never implemented in this system. Not sure whether to try and get this up and running or to part with it so someone else can have a go and focus on the Meiko. Andrew ---------------- Andrew Back a at smokebelch.org

Don Maslin/Archiving system software (was: ftp archives disappearing?)

by Billy.Pettit＠wdc.com

Hex Star wrote: The Russian comment is that if someone here does speak russian it would be possible to get Russian hosting in Russia which would prevent us from having to deal with US copyright issues and thus be able to upload whatever we want should some hosting actually get setup, I have 20GB+ of mac files I'd be willing to upload to the archive :-) Billy: I was going to avoid commenting on Hex Star chiding the list for not giving him all our files. But this is too much - Proposing to use a criminal to get around copyright laws. There is enough bull shit going on right now with the US using criminal governments to torture prisoners so that US laws won't be broken. Is that now the modus operandi of US citizens? This is going too far - proposing that we deliberately break the law so this young fellow can get all the software he wants. Isn't it about time to end this thread and ask Hex Star to stop harassing the list? And Hex Star, please learn how to write a sentence. Your messages are almost incoherent - long rambling lines of text with no beginning or end. Surely your keyboard has a Shift key and a period key; please use them and state your ideas more succinctly. Billy
