I recently visited the Minuteman II launch control facility in South Dakota, and was curious about the computers used there. Here's a photo of the rack, with the Boeing part numbers visible: http://i.imgur.com/KTaW3Il.jpg Some Googling of those numbers didn't really reveal much. People love to talk about the guidance computer in the missile itself, but I can't find much about what they used when turning the keys. I like the little placard on the computer about encrypted data in memory. The whole place is worth a visit if you're out that way. Does anyone have more information on these? Thanks! -- Ben Sinclair ben at bensinclair.com

PDP-1 in Verilog (Incomplete) + More

by cube1＠charter.net

Sorry, not interested. My next project of that sort is for the IBM 1410.

Would you be interested in implementing this microcontroller in VHDL? I'm trying to learn VHDL, but my many projects keep wanting my time. :) I believe there is plenty of reference material for you to use. I've collected some documentation myself that I would be happy to share if need be. Please let me know what you think.

PDP-1 in Verilog (Incomplete) + More

by jan＠janadelsbach.com

Hi all, At the time I've released my DG NOVA in Verilog I was also working on a PDP-1 in Verilog. Since I haven't touched the thing for quite some time I've decided to just release it before it catches dust. So far it can execute all kinds of programs, limitation is that they may not use IO as I haven't implemented the latter yet. (So essentially the same state as my DG NOVA implementation) It also supports optionally some PDP-1D features in the OPR and SKP instruction groups. Interrupts are implemented but untested. I'm not sure in which state I left the IOT controller if it works then both SBS and SBS16 might be usable. TL;DR: https://github.com/Jside/pdp1 The RCA110 was the project I was working on before I started the DG NOVA, it can execute some instructions but there is to much ambiguity in the reference manual on bitsavers in some cases which led me to abandon it. Especially since there is no software to cross-check. So for reference you can get it here: https://github.com/Jside/rca110 I wanted to mess around a bit with Chisel (a new HDL language used by the RISCV project) so here is the start of a CDC160 (currently only the instruction decoder): https://github.com/Jside/cdc160 I've also uploaded my DG NOVA to Github: https://github.com/Jside/nova1 MC14500B anyone? http://janadelsbach.com/soft/mc14500b.tar I will occasionally continue working on both the NOVA and PDP-1 (and maybe CDC160?). Also pull requests are welcome. As is obvious I *really* like implementing old computers in HDL languages but I always get stuck around IO since for any kind of flexibility as with an emulator I essentially would need to write a bus wrapper so that a (soft-core) processor executing Linux running an IO server could handle i.e. hard disks and magnetic tapes and that's I think really not worth it. So I might just go over and contribute to an emulator/simulator like SIMH if I'm in an must-implement-an-old-computer/processor mood ;). Regards, Jan

FFS: GE Mark Century programming manual

by silent700＠gmail.com

Here's a beast of a manual that I've scanned and posted. Will send the original for the cost of shipping (assume at least 5lbs of paper here, coming from 60070.) https://dl.dropboxusercontent.com/u/13043699/pics/GECENT.jpg Scan is here: http://chiclassiccomp.org/docs/index.php?dir=%2Fcomputing/GE Looks like numerical control for machining, not strictly a "computer" but certainly an early programmable device. 1970 edition but the earliest date on it is 1962. Can deliver to VCFMW. j

A Final Word (FINAL)

by jwest＠classiccmp.org

One thing I will absolutely not abide here is drama of any kind. Regardless of anyone's sentiments in response to his post one way or the other, the list is no place for that. Suffice it to say, his subject line was correct. That was the final word he'll ever get on this list, and I have made his ban on freenode: #classiccmp permanent as well. For the record, my reasoning for the ban has more to do with other issues of his - not just the ones commonly posted here and on other forums. Please kill this thread, the last thing we need is a low SNR. Best, J

A Final Word

by slandon110＠gmail.com

This is my final word I was recently banned from #classiccmp for selling a machine that was my own, I picked it up for someone else who hadnt paid me for it, sat in my closet for a year now. Hadnt heard from that person, tried contacting them, to no avail, I listed it on ebay the other day, only to wake up to find that I had been banned from #classiccmp for listing that machine. As far as I know its not against the rules to sell my own personal property. I was finally able to get a hold of the person who wanted it and he still does. I am currently arranging a way for him to get it. I know many of you hate me because im this horrible evil scammer pedophile, or thats what you think. Common sense says that if I was a horrible pedophile, I wouldnt have joint custody of my son, But I do. Because of what was posted online over the years. Yes I scammed over 10 years ago, thats in the past, Im not a bad person nor a pedophile. People do change you know. Im a hardworking person who tries his hardest to take care of his kid and family. Yes I enjoy computers.. I enjoy fixing them up and finding them homes. I've been treated terrible in this scene by a number of people. calling me names, you name it. I attended VCF 3 years in a row, Had a blast. This year I will not be attending due to the sheer number of threats I have received. I really wanted to bring my son this year. Hes 10. It would have been fun to share this with him. We really wanted to have a ccmp display during the 2016 Telephone show here in Michigan as well, and you all would have been welcome to come. But if you guy's don't want me in this scene just simply say so, and Ill quietly disappear. Thank you for your time and Good Day

Wanted: IBM AS/400 in NY for a film

by jnc＠mercury.lcs.mit.edu

> From: Evan Koblentz > we always require a signed contract with strict rules about how our > artifacts can/can't be used by renters. I hope the contract includes a very sizeable 'liquidated damages' clause which comes into force when the artifact is significantly damaged (i.e. scraped paint, scratches, etc don't count) or destroyed; that number should be 5-10 times its assessed value. That would be to stop people like the film crew we heard of who borrowed something, deliberately destroyed it as part of a scene, and them calmly paid the lender the assessed value. If they're looking at having to pay a _ton_ of money if they pull that stunt, they're less likely to. Noel

by steve＠oldcomputers.net

I received this email - they want am IBM AS/400 for a film - it doesn't have to work. They will pay for transportation and rent. Near Brooklyn NY I think. Email Bianca below if interested. ====================== Begin forwarded message: > From: Bianca Siu Davies <biancasiudavies at gmail.com> > It does not have to work, it would merely be set dressing for a film. If we could find one by mid-August, that would be great! I'm in New York and I can organize the shipping of it if need be. > > Thanks so much!! > Bianca. > Bianca Siu Davies >>> Art Department Coordinator >>> THE WIZARD OF LIES >>> O: 646-863-7493 >>> C: 415.420.8375 >>>

DEC M705 vs M7050 in PC05

by j＠ckrubin.us

If you were following Joerg Hoppe's recent PC05 auction on eBay, you might have noticed that his system had an M705 in the backplane where I would have expected an M7050. This is the way he received it and the restored unit works as it should. Clearly the cards are similar but different but are they interchangeable? Would the backplane wiring be different and if so where would this be recorded? My copy of the PC04/05 maintenance manual (DEC-00-PCOA-D(1)) makes no mention of the M705 in this location. The PC04/05 print set on Bitsavers has the M705 on the module utilization list (p45) but crossed out with no reference notes. There is an ECO list on the sheet, showing PC05 ECO's 3, 16 and 30 but no specifics. Is there an available ECO log that would cover these notes? Then there's the K303, but that's another story...
