Hi Guys I'm due at the screen printers on Wednesday. I've now incorporated what I have gleaned from the loan panel into the drawing set. For 8/e panels we now have the following layers to be printed. _On the front: _ First will be a translucent matte base coat to give a satin finish. It looks black because of the black layer on the back of the panel. Then either the Terracotta or the Amber and finally white. At this point the panel is neither a Type A or Type B . White only detail in the selector switch area and the dividers between lamp groups can then be added to give the panel its identity. There are two small screen separations to allow this to be done. _On the back:_ The 8/e back side (/f and /m differ I'll explain that later) has a heavy black layer with clear round areas for the lamps / LEDS to shine through. In just the lamp area there's another translucent matte layer. This and the one on the front act to diffuse the light coming from the lamps/LEDS. Thats seven layers in total and they have to be dried after each layer goes on. Each one needs a silk screen and when being printed registration is critical. Its a skilled job and not one I would care to have to do. More news when I have it. Rod (Panelman) Smallwood

flash (or ide) storage for unibus 11?

flash (or ide) storage for unibus 11?

I think that was probably Brad Parker's prototype? > Anyone know of a good project to add some modern storage Available today, no. But there are a number of projects which will probably be cranking out UNIBUS DEC controller emulators with modern storage backends. I gather Guy's MEM11 project will probably eventually spin off a version with a larger disk, and Bridgham and I are planning on doing a UNIBUS version of our card once the QBUS version is done. (Actually, ours is planned to include an ENABLE too, with 4MB of memory, for those of us with 34's, 40's, 45's, etc.) Any more? Noel

flash (or ide) storage for unibus 11?

by jwest＠classiccmp.org

I'm looking for a modern storage (ie. anywhere from 100mb to "huge") device for an 11/44. I think I have seen a few hobbyist projects that were flash based, I thought I saw one that was an IDE interface.... Long story short I've satisfied the purist in me by putting an RL02 on the machine, but that's just not enough storage for that particular system. Anyone know of a good project to add some modern storage to get me over the available storage on the RL02? J

A Selectric printer...

by tmfdmike＠gmail.com

I have an I/O Selectric device which is badged as, and was originally, an IBM 2970 Reservation Terminal. For better or worse, it was one of those bought up in the late 1970s by a company called 'Western I/O", based out of Scottsdale Arizona. They converted them for home use. One version used a Motorola 6800 to make a nifty-sounding terminal with selectable baud rates etc. I appear to have the 'other' version; a cheap and nasty printer-only conversion with some form of parallel port. Anybody else got one? Docs about them? Parts? Schematics? I'd like to get hold of one of the 'proper' terminal conversion versions... Must be some squirreled away in garages! Alternatively, any doc on the original 2970? There's an incredible dearth of information about what we're once very common devices...

Any AS/400 hackers? Linux question

by tmfdmike＠gmail.com

Might not really be old enough for this audience but it's an obscure enough question! I have an AS/400 9406-S20 - mid 1990s vintage. These things could have what IBM called an 'Integrated Netfinity Server' - basically an Intel PC on a board, using space on AS/400 disk etc. Two such boards work in this machine: the 2852 (Pentium Pro) and 2865 (Pentium II). Both ran NT, and that's well-documented in a Redbook. Both could also allegedly run OS/2 and Netware. it wasn't officially supported I know, but did anyone ever succeed in shoehorning Linux onto either of these boards? If so, how? Official support only came with the next iteration of hardware (which my system can't use), and relied on the 'PC on a board' having USB ports, and involved the use of a USB floppy drive (!) to complete the Linux install process! (I'm at V5R2 btw, and have had NT running on this board) Mike http://www.corestore.org 'No greater love hath a man than he lay down his life for his brother.

ICL Quattro

by supervinx＠libero.it

Hi! I found an ICL Quattro desktop computer. It looks in good shape, I had to repair only the PSU. Powering it up, I see disk activity, but I haven't his (proprietary?) monitor. On the back, I see a bunch of serial ports (DCE? DTE?) and a DB15 connector, I guess for monitor/kbd attachment. I tried to connect a terminal to the serial ports, with null modem and straight settings, but I had no answers. Do someone have some infos about the proprietary monitor/kbd port? Can it be run without the original monitor/kbd system? Or should I think about it as a... doorstopper? :D Thanks! -- Vincenzo (aka Supervinx) --==ooOoo==-- My computer collection: http://www.supervinx.com/OnlineMuseum --==ooOoo==-- You can reach me at: www.supervinx.com www.facebook.com/supervinx http://www.youtube.com/user/supervinx http://www.myspace.com/supervinx

Looking for an IBM manual PDF

by captainkirk359＠gmail.com

Hello all, I'm looking for a PDF copy of IBM manual GC26-3792-8. The System Generation manual for MVS 3.8; the only PDF I found of GC26-3792 is of the -1 version, which is not particularly helpful. I found a DjVu of the manual (via this site: <http://tk3.comlu.com/mvs380/Vintage_Manuals.html>) namely here: <www.classiccmp.org/softlib/manuals/GC26-3792-8/GC26-3792-8.djvu> Unfortunately, downloading the DjVu file does nothing (SumatraPDF on Windows can't render any of the pages, and Evince on Debian 8.2.0 just ignores the file); the Java applet to view it works... except it doesn't play nice with my accessibility needs. So, anyone have a PDF of that manual? Cheers, Christian

Gene Amdahl, Pioneer of Mainframe Computing, Dies at 92

by c.murray.mccullough＠gmail.com

Stephan, referring to the article in The New York Times, mentions Amdal, Cray and Wozniak: Pioneers in computing whether large, super-large or small(micro). Who knows of, in the microcomputing world, Amdahl and Cray? One wonders! Happy computing, Murray :)
