Hi Liam, I have already done that. Their reply was: "" Henk, We do not make the support frame shown in your photo. The 101 key frames we use require different membranes, keys, and electronics. You would be better off purchasing a new Classic keyboard. Thank you for the inquiry and your interest in our keyboards. Best regards, Customer Service "" H.

At least they're not claiming the picture is of the one they're selling. In the text they say it's a "stock" picture and the one they're selling is blue. BLS

So...What a mess, huh? ;o)

There is a ground level exit so no stairs have to be climbed. Also, he says it splits into two units. He said it was running in 1986 and decommissioned by IBM so there's a chance it will run again.

Hi Will, Good question. I would like to put the new owners name on my remaining system/3 list. Looking at the bidding history, he (or she) really wanted it. Or is it again a person with deep pockets who likes to remain unknown. I hope not. I agree with you completely, if feasible do NOT split it. This will also increase the chance that it will run again.

Hi, Can anyone help me with a copy of the micro-code listing of the IBM System/32 ? "Dutch" Ownen wrote the System/3 model 10 emulator and I wrote it for the model 15. The System/3 instruction set was emulated with micro-code on the S/32. It would be a nice project to write a S/32 micro-code emulator that emulates the S/3 again. The micro-code listing was part of the CE documentation that came with the System/32. A PDF scan would be great. THX Henk www.ibmsystem3.nl

I have a board from the CPU stack of an Amdahl 5870 which I looked after briefly in the early 1990's. It had been upgraded from a 5860 by the additon of an attached processor. Mine doesn't have any plumbing or copper sheeting and looks like the boards depicted about half way down this page: https://www.staff.ncl.ac.uk/roger.broughton/museum/circuitry/AMDAHL.htm I don't know for sure but I suspect other members of the 58xx series were similarly constructed. If your units are complete CPUs, they seem to be much more compact units with more agressive cooling than any of the 58xx series that I am familiar with. Regards, Peter Coghlan.

Hi Peter, Mark, Thanks for your replies. Looking at the brochure it was a 5990 CPU. I now also recognise the operaror panel in it. The copper CPU must be from a CPU after the 5990. Probably an Amdahl 5995. Regards Henk main

This is very cool, Henk.. posterity will appreciate your work (I know I do, and I've never laid hands on a 360). Allow me to point out, that while Facebook et al are "worth" more today than all of IBM's cumulative assets & production put together, there WILL NEVER BE A TWITTER MUSEUM! ;-) I find that somewhat comforting.

From: Al Kossow Sent: Sunday, September 21, 2014 10:04 AM Several of our 360s came from ACM, but the first was acquired Perth, Australia, by my friend and former colleague Ian King. He was written up in the Wall Street Journal (with several errors of fact) for that adventure. I'm not sure why you make this comment. There's nothing about the Smithsonian on the page I visited, and we certainly have never made any claims to that provenance.

A couple of things: The two machines in Japan need to be added. The ex-Stumpf model 22 - nobody has seen or heard of that machine for nearly twenty years. It probably still exists, but there is a non-trivial chance that it is gone. Certainly in the last 20 years a few S/360s have been junked. -- Will

Thank you for clarifying this - I (and others) suspected the machine was a mockup. I was contacted by the prop guys (although they did not mention Mad Men) a year or so back, and was seriously thinking about loaning some of my pieces (card machines that a model 30 would have used - they insisted on a model 30), until they mentioned that the machines might be "modified" to suit the production.

Absolutely. I can think of at least three reasons for antique furniture. They apply pretty well to computers, too: 1. Hassle. Insurance value reflects the cost of buing a replacement. With antiques and stuff, as most people on this list have probably found with their computers, it doesn't reflect the hassle of actually finding that replacement! 2. Provenance. With antique furniture, there is also the fact that even if you do find a replacement, it is no longer the item that has been in the family for generations, ever since Great-Grandmother received it as a wedding present from the Lord of the Manor, whose furniture she had polished so well when she worked there... 3. Uniqueness. Many antiques are hand made and unique. Insurance covers buying something to replace it, but you never get the exact piece back. Normally you'd expect the film-makers to go out and buy something at auction if they want to trash it. But it's the same impossible-to-find pieces that would cause their owners the most grief for which they have to resort to such chicanery... Philip.

Actually, I don't think the type M is as robust as the older (PC / XT keyboard and the 84 key AT keyboard). The older ones had a lot more metal in them and were not assembled by heat stakes. Incidentally, the type M uses conventional membrane swtich contacts (operated byu the flaps), the older ones arew capacitive and presumably more reliable. I ahve had a couple of type M's where the heat stakes have broken away during normal use. The result is that some of the flaps move out of position and those keeys then fail to work (or in some cases appear to be stuck down). Anyway, whact I did to mine was to cut the black key frame into rows. Then dril lout all the heat stake posts and tap them M2.5. Then fit screws through them. Assemble a row of flaps at a time to the baseplate/ memberane layers and fix them with M2.5 nuts. How bad is it? Is it just split into rows (not a problem, it's easier to assmble that way) or are some of the key locations broken? AFAIK it was never avaialble as a spare part from IBM (other than as the complete keyswitch assembly, less most of the keycaps). If you can find anotehr broken keyboard soe that you can have all rows intact, then you can fit parts of the 2 frames to the same baseplate. Why not? I think they did. The older capacitve keyboards had one of those sqaure iBM metal-can ICs in them, so I would think that was an IBM design/manufacture. -tony
