Getting Ready to the NeXT Adventure at SMECC

by COURYHOUSE＠aol.com

Getting Ready to the NeXT Adventure at SMECC Found some of the boxes of cables, the mouse, trays for the laser printer. Another crate had these slipcases with lots of 8x11 NeXT Manuals in them... In addition there are CDs Located the CUBE, the Monitor and Keyboard need to find where the printer is. I know it is there! A couple weeks back I was given a copy of "Steve Jobs & the Next Big Thing" and started reading it. Very Interesting although it was done before apple got jobs back and from what I see in other sources adapted the NeXT software to be OS-X. I would interested in hearing from the group to how accurate they consider this book. I am also interested an any suggestions how I handle the initial power up... this whole machine is a new thing to me as Macs and NeXT are systems I never used back in the 'the day' Any advice on or off list appreciated! After I get it running, assuming it will I will set it in the display area and will need to look for some colorful advertising stuff to help decorate the display. If is totally roached and will not fire up then I guess it becomes a static display ( until some other parts units show up?) Thanks Ed# _www.smecc,org_ (http://www.smecc,org)

Datapoint

by jnc＠mercury.lcs.mit.edu

So I just bought, and have been avidly reading: Lamont Wood, "Datapoint: The Lost Story of the Texans Who Invented the Personal Computer Revolution" and I was wondering what other people thought of it. (For those who aren't familiar with it, his thesis is in the sub-title. He reckons the first Datapoint machine, the 2200 - announced 1970, shipped 1971 - was the first personal computer, and a direct ancestor of all the PC's out there today. The Intel 8008 - base of the later 8080 and 8086 - was not actually related to the 4004, but instead was done persuant to a contract with Datapoint to provide a CPU for the 2200, to replace its inital CPU, which was built out of discrete chips.) It seems to be a reasonably scholarly work - he did a lot of interviewing of the principals, has made extensive use of archives of contempory written material, and it has some source footnotes (although not as many as would be optimal). So I think he might have a good case.... Any collectors of early Datapoint machines out there on the list? If his thesis is correct (and I think it is) these are very historic machines - up there with Altairs, etc. Noel

This is also known as a DEC H7130C from a KS10. 5V at 30A 5V at 60A 12V at 10A 15V at 3A 5V at 5A I see lots of companies that advertise repair services for these supplies, so the documentation must exist. It would be great if you could find some documentation for these power supplies. -- Michael Thompson

VCFed is restructuring

by evan＠snarc.net

Vintage Computer Federation has big dreams. We?re restructuring our organization to help make them come true. Our mission is to empower collectors, grow the community, and teach everyone about computer history. We especially want to raise interest in computer history among young people. To do so, we are planning many changes. For example, we want to expand the Vintage Computer Festival event series, offer new resources on the vcfed.org site, foster regional chapters, and improve our museum space. There are still other ideas that we hope to share in 2017 and beyond. We firmly believe these goals are attainable and imperative. However, as an all-volunteer unit, there simply isn?t enough time to devote to our cause without overly sacrificing time spent at our regular jobs, being with family, collecting vintage computers, and so on. As such, effective today, Vintage Computer Federation co-founder Evan Koblentz is stepping down as president and accepts the new position of part-time director. Evan is the Federation?s first employee. He reports to the board. Evan will continue day-to-day administration of the Federation and will embark on new fundraising initiatives. Erik Klein, formerly vice president, is now board chairman. Jeffrey Brace, also formerly a vice president, is now vice-chairman. Corey Cohen retains his role as business manager. We feel this new structure will help us gain resources, meet our goals, and continue to save and teach computer history for many years to come. Vintage Computer Federation Inc. is a 501(c) non-profit organization.

> From: Al Kossow > Stack Limit That's there - that's the KJ11. > From: Tony Duell > KW11-L line time clock? I don't really consider the LTC as a CPU option. It's on the actual UNIBUS, it's just in a specially wired UNIBUS slot that's only one slot wide, and only has BR/G6 and D6/7 wired to it. Yes, in this case that slot is in the CPU, so one can make an argument... Noel

ka... ching!

> From: Alexandre Souza > the outsider comes and says "if he is selling for 1000, I'll sell mine > for 1100 and see what happens" and the price goes to actual unpayable > levels. Except it usually doesn't work. Look at that PDP-8 that was listed for ever at $25K. No takers. And this PDP-11/04: http://www.ebay.com/itm/172192522620 which does, after all, have the programmer's console, and has been listed for months at $2K. Noel

> From: William Degnan > Some of the CPU options not present. Huh? The KT11-D is there, as is the KE11-E and KE11-E, and even a KJ11-A of sorts (might be an after-market one, doesn't have the standard DEC handle). What other 11/40 CPU options are there? Noel

My H316 environment

by hachti＠hachti.de

Hi folks, if you're interested... I have made available my Honeywell H316 environment. Consists of all you need to run the machine and more. Contains software to split and rearrange libraries. The Fortran IV compiler SOURCE. The assembler. Scripts that run compiler and assembler transparently on files (with help of SIMH). Plotter library. Mandelbrot program. Much more. Only SIMH is needed. The rest should be done by the Makefile. It's just all I have. http://gitweb.hachti.de/git/h316.git :-) -- Dipl.-Inf.

pinouts for LH Research Super-Mite and Mighty-Mite-A sense connectors

by aek＠bitsavers.org

I'm working on documenting these supplies, since there seems to be almost nothing on them on the web of use. There is a list of what is on the 9 pin molex on the SM, but no actual pinout. Same for the 15 pin D on the MMA, but at least there are enough pictures around to be able to assume the sense lines are on 1 and 2. The general form of the part numbers for them starts with 2 or 3 letters (TM,MM,MMA,SM) a rough power rating code (1-7) and the number of outputs (1-5) a dash, then model number probably encoding supply outputs/amps. This is based on looking at a bunch of eBay pictures. They want waaaay too much money for them on there. This all started because I need to fix the MM72s for the Alto. I got the four I took a look at fixed by replacing all of the 19000uF/7.5v caps. All of them were dried out. Not a huge surprise since they were from around 1978. Measured the rest of the caps in them with an in circuit capacitance/ESR meter and they were all reasonable, even the 1400uf/200v ones, which I had some spares for, but are much harder to find in the right size than the 19mF ones. Switching supplies from the mid 70's are NOISY (10-20mV on all four supplies)

HP 9000 Model 550 sold on eBay

by glen.slick＠gmail.com

I was wondering if this item would attract much attention. http://www.ebay.com/itm/262642624725 Sold for $787 this evening. I don't know anything about these systems. Looks interesting, but this bit of text didn't sound too encouraging: "The 550s have not held up particularly well over time. As of 2013, the museum had two units. Both units have non-functioning power supplies. The system control boards are also subject to damage from battery corrosion." http://www.hpmuseum.net/display_item.php?hw=581 Also this bit of text about the HP-UX 5.0 Operating System: "The downloadable file is an image of the system software tape for HP-UX on 500 Series computers. It was made from a 150ft tape. We obtained 47 read errors while imaging the tape, so it's probably not entirely intact, and we don't have a working 500 Series machine to check. However, the file contents of the tape are readable by issuing the BASIC CAT command from a 300 Series computer." http://hpmuseum.net/display_item.php?sw=534 Just curious if anyone knows much about these systems and if anyone has one in working condition. What might the chances be for whoever bought this system to get it into any sort of working setup? Does anyone else have software for these squirreled away in their collections?
