I once had FexEx Ground destroy the entire packaging of a shipment (one of those rigid plastic tubs, sealed closed with those tension tapes) so badly they had to build entirely new packaging for it. Assume _all_ shippers will throw your item across the room, and pack accordingly - because they will. Noel

Mac SE (HD/FD) and 40GB APS Tech HDD

by david＠kdbarto.org

I?ve just come into possession of both of these units. The Mac has a 20MB internal HD and doesn?t startup. There is no happy mac or boot chime. The video is just a single line in the middle of the screen. The HDD spins up and wants to be formatted by any Mac I?ve got that has USB on it. If anyone wants either of these let me know (San Diego area of California). If I hear nothing both will go to the electronic recycler next Saturday. David

Too many DEC binders

by shadoooo＠gmail.com

Hello, I also have a bunch of manuals, mainly for rt11, which aren't available in bitsavers. I always thought of bitsavers as the "whole" archive for DEC stuff, however time ago, sorting these manuals, I found they where available only on Manx or Antonio Carlini's archive. Many manuals then are available on other sites, etc Now the question: why collected manuals from other sites couldn't be added to bitsavers too? Thanks Andrea

ADM-3A question

by charlesmorris800＠centurytel.net

Today I got home and my Mouser order had arrived. I soldered in the new 6-position DIP switch and popped a new 1488 in the socket. Nice RS232 data coming out... for about 10 seconds, then the transmit data line went to around +2 volts and stayed there. WTF. Tried another one, same thing. Went back to the first new chip, same thing - so it's not blown (and maybe the old one wasn't either). OK, it has to be the power supplies. Again. Sure enough, +12 was sinking slowly until it was near zero at which point the RS232 output basically went floating... This looked familiar and it didn't take long to discover that the CT on the transformer for the + and - 12 volt supplies was open again!! This time it was the wire from the transformer broken as it entered the Molex connector. Fixed that, back in business. I am amazed that none of the epoxy drop tantalums on the high leg with the open neutral have blown. Maybe they're open circuit :) Also I don't know what gorilla at the salvage place was connecting/disconnecting until he found a combo of base, board and monitor that worked. --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

Too many DEC binders

by aaron＠aaronsplace.co.uk

I have a full book case of DEC binders, each containing one or more manuals. I went through the lot of it this evening and checked to see what was on bitsavers. It seems an awful lot of it is not available. I cannot bring myself to dispose of any of it until it is digitised, but keeping hold of this much paper is not practical for me. I'm going to try to scan as much as I can. The full list of what I have is available at the link below. It is mostly mid 1980's VAX/VMS stuff.. If anyone would like one of the manuals for the cost of shipping, I'd gladly send it over to you. http://aaronsplace.co.uk/dec-manuals.html *** If there is anything you consider a priority in terms of being scanned, please let me know and I'll try to do it sooner, rather than later. *** Finally, I'd like to mention that these manuals came from a friend, Marc, who passed away early last year. Marc used to be somewhat active on this list (more so the #classiccmp IRC channel). A friend of Marc will be participating in a walk for the Campaign Against Living Miserably (CALM) charity. If anyone is willing to donate (even a small amount), it would mean a lot to me. CALM is a charity supporting men who suffer from depression - one of the leading killers of men under 45 in the UK. https://www.justgiving.com/fundraising/losthourswalk2019inmemoryofmarc Many thanks, Aaron

Raspberry Pi write cycles

No matter what I ran > on that Pi, it would corrupt its SD cards in a matter of weeks (the > symptom was that the fourth bit of some bytes would just stick on). I > assume it was just something broken in the Pi itself. You can simply root off of a USB disk by changing the "root=" parameter in cmdline.txt on the FAT partition on your SD card. Since the card won't otherwise be used unless you mount it if you do this, your next card should last forever. I've got a Suptronics x830 board and enclosure with an 8 TB drive which boots this way. Any Pi processor newer than the original ARM1176JZ should run NetBSD pretty well. My 900 MHz Pi 2 runs NetBSD/vax almost as fast as a VAXstation 4000/30 (VLC), which is about 5 VUPS. An original Pi or Pi Zero should be able to emulate a VAX at least as fast as an 11/780. One issue with CPU intensive things on Raspberry Pis is that even if your power supply provides plenty of current, the slightest drop in voltage can cause throttling. If you know your power supply is good but see a lightning symbol anyway, add "avoid_warnings=2" to config.txt on your SD card's FAT partition. John

Update: Shipping 50 lb computer from Zell am See, Austria to CA.

by tosteve＠yahoo.com

Well, I knew the computer, just not the city. It's Zell am See, a small town in western Autria, far from everywhere it seems. The computer is a Datapoint 2200 - 50lbs, 10x19x20 inches. I want to get it shipped to Calfornia, where I live. The cheapest option is to just use local Austria mail, but max dimensions are 60x60x100cm, or 23.5x23.5x40 inches. That would leave just 2-inches on each of two sides for padding. Best option - remove the plastic cover and mail it separately. Correct me if I'm wrong, but the entire bottom of the computer seems to be a solid piece of metal, like the Apple III = very strudy. The back is a giant metal heat sink. I think it's do-able, do you?

bit-slice and microcode discussion list

I dunno; those were all about picking _addresses_ for instructions, such that the next instruction was coming up to the heads as the last one completed. The _order_ of execution wasn't changed, there was no issue of contention for computing elements, etc - i.e. all the things ones think of a CISC->VLIW translation as doing. Noel

bit-slice and microcode discussion list

by spacewar＠gmail.com

On another mailing list, someone asked if there was any list specifically about bit-slice design and microcoding. I don't know of one, so I've created a new mailing list specifically for those topics: http://lists.brouhaha.com/mailman/listinfo/bit-slicers The intent is for the list to cover technical discussion of bit-slice hardware design and/or microcoding. In other words, discussion of microcoding that doesn't use bit-slice hardware is fine.

KE11-A craze (Was: Current MANX location)

by jnc＠mercury.lcs.mit.edu

> KE11-A Field Maintenance Print Set > http://manx-docs.org/details.php/1,9358 Speaking of KE11-A's, does anyone know what's behind the bidding wars on recent eBay KE11-A component board listings, e.g.: https://www.ebay.com/itm/372685033144 AFAIK, the boards (a complete set is an M7210, M7211, M827, and two M234's) are pretty useless without the custom backplane, so do some people have such, or do they not know they need the backplane, or what? I do have a couple of BB11's (they came in an old custom interface I bought), and the KE11-A FMPS includes the backplane wiring, so if I were interested enough to devote the time to wiring a replacement backplane, I could probably get one running, but they aren't _that_ interesting...

KE11-A craze (Was: Current MANX location)

by paulp1＠gmail.com

I was one of the bidders. I have a KE11 backplane and it is populated. I just wanted some spare boards. You don't see these boards that often. I am hoping that a backplane would appear too. The seller seems to have some early pdp11 backplanes.

PDP-11/34's with Octal Programmers Console (Model A or C) and the rest of the peripherals; etc.

by S2ci.777＠Live.COM

Hi Jim, Do you still have any systems and/or peripherals left? I'm looking for a PDP-11/34 Model A or C (Preferably C) with the Octal Programmers Console and Digital Display along with peripherals. Please let me know what you have. Would you be willing to accept monthly payments because I'm a disabled vet and get paid within the first week of each month? I have a pickup truck and I'm coming from the Cleburne, TX area. Would be willing to meet you half way. Looking forward to your reply. Most sincere and all the best, Scott

Oh, speaking of KE11-B's, does anyone have either the Technical or User's manual for it (I couldn't locate either)? It appears to be a program-compatible re-implementation of the KE11-A, on a single hex board, but it'd be nice to confirm that, and find out more about it. E.g. does it go in a MUD slot? (Yes, with the prints, I could eventually work out the answers to most questions - the prints do contain the PROM contents - but I'm lazy... :-) Noel

The whole list is here: http://wwcm.synology.me/scanned.html They have a lot of good stuff (I just found an MD10 brochure there, which is AFAIK the only piece of MD10 documentation left in the world, other than a section in a PDP-10 manual). I need to go through it and see what else they have that I'm missing... Noel
