the old logo also had this terminal, or something very close. Nothing better than the ADM3 IYAM and YCAM. On Tue, Oct 13, 2015 at 10:48 PM, Connor Krukosky <connork at connorsdomain.com -- Bill

ADM3-style terminal just felt right, from an artistic perspective. Shape, color, etc.

I also noticed that the outer circumference (outer most part of the logo) doesn't appear to be a true circle, but more polygonal instead! (look *really* carefully) Was is created using some 3d rendering software???

Good eye! Yes, we used a 3D CAD program, so that someday we could make models of the logo.

OK so if we agree there are three classes computer Namely Micro,Mini, and Mainframe. It follows that there must be three classes of vintage computer. We dont need patches with pictures but it should say what type of system we major in For example Rod's Retro Restorations - IBM360 Rod Smallwood On 14/10/2015 11:57, william degnan wrote: -- Wanted : KDJ11-E M8981 KK8-E M8300 KK8-E M8310 KK8-E M8320 KK8-E M8330

You want sentimental? I have a VT100 that I know I sold to a customer in 1975 whilst at DEC and that came back a couple of years ago in a clearout pile from I know not where. I still had my old day book I in which kept the serial numbers and there it was!! Needless to say surprise was not the one half of it! Forty years is a good age for any terminal. Its all cleaned up and looks and works as well as the day it came off the line at Westfield. DEC had many plants like Westfield in Massachusetts. Most companies would have an interplant bus service. DEC had a helicopter service. The pilots had nealy all been in Vietnam. I heard the following story at a sales meeting.: The helicopters would usually rise gently to 2000' and set course fo the next plant. Unless you asked how they had got on in SE Asia. Then you got the "how to get to the drop zone whilst avoiding AAA, smallarms fire and ground to air missiles demo".

Well, that may be a real challenge, then. SLT is simple logic, but the art of chip passivation was not totally figured out back then, and so the chips degraded from moisture and oxygen exposure. Do you have any idea what shape the CPU is in? Have you powered it on? Jon

I don't think we got to "Micro, Mini and Mainframe" until we got to 2nd and third generation computers.... ... 1st generation Valve Computers like the Bendix , Pegasus, EDVAC, Manchester MK1, CSIRAC were just "Computers" and don't conform to the above classes.... Dave

That part of the image is only meant to * evoke * a terminal -- which it did.

My PDP-8/L, PDP-12 and PDP-11/20 are all chock full of the stuff - mostly SSI but a little MSI. My TI TTL Data Book is copyright 1973, and I have not come across much in the 7400 series TTL that isn't in there. (On the other hand, the EE lab course on computer design was done using DTL logic, with the interconnects using re-purposed IBM unit record machine plugboards). JRJ

Something a bit bigger than a mini. I think some marketeers tried to use that term for their answer to the VAX. It obviously didn't go very far, given that hardly anyone remembers the term. I'm not sure who specifically used it. Prime, perhaps? paul

With out going into detail and whilst working in Germany in 1969 I pulled a few Saturday night operator shifts for cash in hand on a big Nixdorf system. Just to help out a friend who did not like being there on her own. The Computer room was air conditioned and filtered down to microns. Being Germany it was kept clinically clean and a bit on the cool side. It took us a while to find a nice warm air outlet round the back of a row of tape drives. A quick trip to the medical room to borrow some blankets and we were all set. Now we would not be cold wating for a job to run. Contrary to your remaks I did not lose a lover.

However, apparently the comfy cushions of the Cray were not so inhospitable to one pair of mammals that consummated their relationship on them in a certain MN data center during one late night shift.
