Need some Sun VME boards... (and if someone has a power supply...)
Folks, I have been able to get the Sun 3/110 to boot using the SCSI2SD board as I had asked about earlier (if you want to see the details of what I did, I posted to the sun-rescue list...) However, I can't seem to get more that 4mb to work in the 3/110 chassis ( the 2nd chassis I have is 240v, and so far that doesn't look like it's switchable for use in 115v land...) I've tried the two 4mb boards I have ( both 501-1132 boards ) one has a gouge in the ground plane but the bulk of the ground plane is intact and one says Parity Error 3/17/16 ( not my writing, from the person I got it from ) so I'm assuming that would work but generate an error, similar to Clearpoint board I have that I can't figure out jumpers for. However I can't get the machine to even boot with the boards in. In both cases the lights on the CPU board all light up. Which indicates some form of reset. I've checked the boards dip switches. They are set according to the FEH as 3 on U3118 and 4 on U3119. Jumper J3102 is jumped as well. I've tried them with the VME Bus Px03 and Px04 both jumpered and unjumpered. Same results in all cases. I don't think it's a power issue, as the machine boots with 3 cards ( I.e. 8mb incompatible sun board or Clearpoint SNXRAM card, with SCSI card in both cases ). I've tried with and without SCSI card. All same results. S, question is, do I just have two bad 4mb cards? Am I missing some setting? I don't see anything to set on CPU board. If so anybody got memory cards they're willing to trade that would work in a 3/110? I've got an 8mb 501-1102 or a 32mb 501-1254 32 mb card to trade, memory wise. I am trying to build up 2 3/110 machines, so would like 2 4mb boards at least. I've also got a 3/110 cpu board that has a blown cap to replace but otherwise works, and a couple SMD drive controller boards. I also just realized I have a a Sun 2 VME SCSI board - ( 501-1149 * combo: 501-1045 "Sun-2" SCSI in 270-1059 6U/9U VME ) And of course if anybody has a spare 3/1xx power supply that is configured for 115v also be interested in that. ( and another SCSI card with an external connection would be useful ) Earl

Computervision CADDS distribution carts are weird
I ran into an interesting problem. Eric Smith's copytape program assumes two tape marks in a row is logical end of tape and stops reading. I've had problems with this before with MPE store tapes, because they put two file marks at the start of tape so I just keep reading until I get 10 errors in a row. That also lets me read anything after a logical EOT on 1/2" tape. Well.. CV is even weirder. One some CV software distribution carts EVERY file has two file marks between them. I don't expect anyone to have to archive any of these, but I wanted to get this written down somewhere.
VCF/PNW Exhibit & Trip Report - The Old Calculator Museum
Hi, everyone, Myself and my friend Mike, representing the Old Calculator Museum, exhibited the line of Wang Laboratories electronic calculators at the Vintage Computer Federation's Vintage Computer Festival/Pacific Northwest edition, at the Living Computer Museum+Labs in Seattle, Washington this past weekend. This was the 2nd annual VCF/PNW, and it was clearly a success, as it was significantly larger than the first event last year (which I went to, but didn't exhibit at). There were 30 exhibits, all of which were really interesting, and a good-sized consignment area, as well as quite a group of guest speakers who had interesting topics to present. Of course, being held in the Living Computer Museum+Labs was a bonus, as the museum is an amazing place, with lots of vintage computers up and running and accessible for people to actually use and experience. The Old Calculator Museum exhibit consisted of a Wang LOCI-2 and punched card readers (1st and 2nd-generation card readers), a Wang 360E w/320K keyboard/display unit;362E with 370 Programmer and 371 Punched Card Reader; 360SE 4-terminal timeshared calculator package with two 360KT trig keyboards, 360K, and 320K keyboards, all running simultaneously off the 360SE electronics unit; a Wang 720C; Wang 600-14TP; Wang 500-14TP; Wang 462 and 452 Programmable calculators; and a Wang C-52. These are representatives of all of the lines of calculators that Wang Laboratories made during its years in the electronic calculator market (1965-1974). All of the machines were running and available for visitors to play with, with the exception of the LOCI-2 (which has a thermal issue that manifests after about 3 minutes of operation) and the 500-14TP, which has some kind of problem that renders it catatonic that I've not yet had a chance to try to diagnose/repair). Also shown was an original Wang Labs factory spare parts kit for the 300-series calculators & peripherals, another Wang 360SE electronics package opened up so people could see the insides, a number of circuit boards from Wang 300-series keyboard/display units, as well as core memory boards from 300-series electronics packages, core memory and circuit boards from Wang 700-series calculators, and original sales documentation for Wang's 700, 500, and 600-series calculators. The exhibit turned out pretty well, though I didn't have time to make up signs to identify the stuff until we actually got there and made hand-written signs, which turned out to be good enough -- it seems that people could actually read my chicken-scratch handwriting. The signs included the retail price at the time the machine was introduced, and people were stunned that in 1971, a Wang 720C outfitted as the exhibited machine retailed for $7,000. A lot of people asked how much that would be in today's dollars, and I was able to use my phone to find out...about $50,000. The exhibit was almost constantly busy both days for the whole time the museum was open, (10 AM - 5 PM), and the folks were all very careful with the old machines, and had really great questions about them. I was pretty surprised at how much interest there was in these old beasts. The crowd was pretty mixed in age, from folks who actually used examples of the machines in school, to youngsters who were totally shocked that this is what calculators were like 50 years ago.The machines ran the whole time the exhibit was open, and amazingly, despite the old Germanium-based transistors in the Wang 300-series calculators, as well as fussy magnetic rope ROMs and core memory in the 700 and 600-series machines, they ran trouble-free. A lot of folks had trouble getting the machines to give answers they expected because of Wang's unusual math entry method. Once they were given a simple explanation of the way the machines worked, they caught on quickly, and got answers they expected. It was a lot of fun to explain and demonstrate the machines to the visitors. The Wang 370 Programmer hooked up to the 362E electronics package was popular. I had a little program punched up on a card that would perform an iterative approximation of Pi. It'd run for 100 iterations, then stop and display the approximation it had come to thus far. People were fascinated by the "spinning" Nixie Tubes as the machine churned away on the iterations. People also liked the 360KT keyboards hooked up the 360SE simultaneous timeshared calculator electronics package. They enjoyed it when I demonstrated the two 360KT keyboard/display units running the Sine of 45 degrees at the same time. The timesharing between the two terminals was obvious as the calculator switched back and forth between each of the keyboards as the calculation, which takes about 25 seconds, was being performed. Nixie tubes were a big attraction. Many younger folks had never seen them in person before, but almost everyone knew about them. I think that the popularization of Nixie tubes in the form of clocks using Nixie tu

Most all 8 inch drives were synchronous capacitive phased AC motors. That is until 3 phase low voltage motors started showing up on 5.25 disk drives. The ac motors on the 8 inch drives rarely had jumper options for 120/240V AC. Most were fixed voltage and cycles. I can't recall any that I've seen that had a voltage option.

Thanks very much for posting about the NinjaFlex material. That will come

I loved listening to Jean Shepherd on the radio as a kid, spinning yarns
from his own childhood, including his obsession with acquiring a Red Ryder

consolidated many of his best tales into the movie script for, and
narrated, "A Christmas Story", which is now mandatory holiday watching in
our house.
All the Best,

When I started working here at the university in 1982 they used MMI-

been just retired when I started. After this "PALASM" was ported to
the successor of this machine, a VAX-780.
They had also developed an universal crossassembler "UCAMS" (Universal
Cross Assembler for Microprocessors Stuttgart). It started on the
TR-440, was then ported to the VAX, and in 2011 I succeeded to port it
to my PDP8 under OS/8. Many many overlays. :-)
In the "data catalog 1976" Intel advertises many software products

INTERP/40 simulator for 4004 and 4040

MCS-80 crossassembler for 8080
CROMIS cross microprogramming system for i3000 bit slices
In the Motorola "microcomputer development systems and subsystems"
from 1979 Motorola advertises M68EML, a m6800 emulator, M68MPLC
a crosscompiler for MPL ("based an PL/I"), M68SAM, a crosscompiler.

During this work I also understood that the wiki page on Daisy Wheel printing was wrong since they attributed the invention of the Daisy Wheel printing technology to the Qume founder, David Lee. From reading the interview with George Comstock it is evident that the true inventor is Hungarian born Dr Andrew Gabor. A week ago I finally updated the wiki page to reflect this. https://en.wikipedia.org/wiki/Daisy_wheel_printing If someone else has more information and details it could be worthwhile to update the page yet more. Here is btw my HyType II printing som ASCII art. https://www.youtube.com/watch?time_continue=1&v=C5bodpSsFl8 Nice printer. The servo system designed by Andrew Gabor works very well. The speed of the carriage when it moves back to the home position makes you keep fingers on your back not touching anything... > > --Chuck > >
