Re: Wanted: IBM AS/400 in NY for a film
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. And what will they pay for damage or destruction? MARCH is working on this deal, since metro NYC is our backyard. For anyone interested: we always require a signed contract with strict rules about how our artifacts can/can't be used by renters. In the past few years we did most of the computers for "The Americans", "Halt & Catch Fire", Apple/MSFT episode of "American Genius", and a major Hollywood film that I can't reveal, along with several smaller deals. In each case, the contract requires proof of their insurance; numerous rules about transportation, storage, and (of course) actual usage; and additional rules requiring MARCH delegates to on-site if anything needs to be up and running. Everything from wrapping to power to proximity of any open beverages is covered. Related: there are some artifacts we won't rent at any price due to value/rarity/size/etc.

I get the jab you're taking at latter-day Audiophool idiocy, but you won't find any gold-plated OFC business in any of the vintage gear I typically work with. But as far as gold plating goes, gold is a good conductor, it solders very well, it doesn't tarnish and its ductility promotes solid connections on screw terminals - it's really these characteristics that make it somewhat desirable in certain applications. So it's not so much that gold "sounds better", it's that it allows one to make connections that work better. But it does tend to wear quickly. While I don't want to go /too/ OT here, I do want to clear up one common misconception regarding gold plating. It isn't that gold itself wets easily when soldering...the tin content of the solder actually dissolves the gold and the solder bonds to the underlying metal surface. This can also lead to gold embrittlement of the solder joint, and while it generally wasn't as big of an issue with larger through-hole solder joints (such as with older semiconductors which had gold plated leads), it did become a major issue for SMD boards with gold plated pads, and especially with BGA components. This is why in high reliability applications, industry practice has been to pre-tin gold plated surfaces which are to be soldered, using a two step solder bath. The first being more sacrificial which will collect much of the gold, and a second to catch anything which might still be left.

Actually, that problem is more likely to be lack of communication and not
giving a shit. The people making decisions at the time of filming
("here's what we need to do") might not even know how much the deposit
was (nor care). The high deposit might convey the need for care to the
people renting it, but that doesn't get through to OTHER people who are
the ones ending up using it.
Hence, set a deposit that is an amount that you would be glad to sell the
item for, and NEVER loan out something that you would not want to part
with.
Re: Wanted: IBM AS/400 in NY for a film
> 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

As others have said, that 'liquidated damges' amount may be lost in the noise compared to the total budget for the film. So be careful. Be very careful. And no matter what the amount is, remember you can't hack banknotes. If it's a rare machine, one you have spent a long time tracking down, etc, then the money is probably worth a lot less to you. There are items in my collection that I would not lend out even if the amount was say $10million. Period. -tony
A Final Word
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

But it also good that there are people who aren't, because that gives not-yet-bad actors an incentive to never start. (Not, of course, that that is to condone the threats slandon110 has received - or says he has, at least, and I'm willing to treat the claim as true for purposes of this email.

Nor have I heard any threats made against you (and certainly not your son.) But you're certainly a thief. Many consider depriving people of their hard earned money as horrible and evil. It has not been ten years since you scammed people as you promised to refund the rest of the money owed to me after last years VCFMW and you never did so. I was due the money because you took money from me for shipping and then never shipped the items and didn't refund the money. Your whole solution was that I could drive hundeds of miles to pick up items I had already paid you to ship (with you keeping the shipping money as well.) These are all facts. No name calling. Personally I had thought you were trying to turn over a new leaf, but that wasn't the case. I doubt you are now either. You're certainly not the poor martyred saint you're trying to make yourself out to be. I've had great luck dealing with people in my hobbies including vintage computing. Almost all are trustworthy and act as members of the collecting community. You do not and the community would be better if you were to "quietly disappear." You've made your bed by your admitted scamming people ten years ago (and by the facts which show you're still at it.) Todd

PDP-1 in Verilog (Incomplete) + More
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

Re: DEC M705 vs M7050 in PC05
Hi, 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... While repairing I found these functional differences between M705- and M7050-based PC05's: http://retrocmp.com/stories/dec-pc05-papertape/240-dec-pc05-model-evolution Differences are the generation of the reader's data clock signal (Stepper motor position vs. feed hole pulse) and the "end of tape" condition" (tape photo cell vs. feed hole timeout).

AM Varityper (phototypesetter)
I don't know how many of you were familiar with the Addressograph-Multigraph (AM) Varityper phototypesetting systems. Basically small computers with floppy drives and a (very nice) terminal--and a big box that held quite a number of photo "font" disks. Basically worked by shining a light through a specific disk and character onto light-sensitive paper. Produced gorgeous print ready copy. Compugraphic and Mergenthaler had similar systems and I think there were also several other competitors as well. At any rate, a pile of 8" HS floppies will be landing here in the near future. Does anyone have any leads on Varityper service manuals or anything might help me with the task of figuring out what on the disks?

If you're talking about the 8008(sic)-based unit which had the "developer" unit contained within it ... you're giving me a nervous tic. If for some reason of insanity you want to run this thing, you *must* keep it well-cooled. Otherwise the font disks spin ... too slowly. At the university newspaper we would keep the classified ads that it mis-typset and run them every April 1. The best was the ad for the "1876 Volkswagen Qabbit with automatic sransmisrion". Thankfully I have forgotten the others. And yes, if it messed up, you got to retype all those column inches all over again. mcl

Basically, this thing, or a variation thereof: http://www.ricomputermuseum.org/Home/equipment/varityper Probably, given the time, 8080/z80 or 8085, I would guess. I don't have the unit, just the floppies. --Chuck

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