I'm not sure that I'm comfortable asking this, but here goes.... I ran into the famous Michael Holley (www.swtpc.com) at VCF West and had a pleasant conversation. I've emailed him several times at the address on his web page, but haven't had a reply. I'm wondering if he ever hangs out on cctech and if not, if there is someone that knows of a different email and could let him know that I would like to chat with him.

Looking for a MXV11 board (QBus)

by azd30＠telus.net

Hi, As per the subject, I'm wondering if anyone has a spare MXV11 that they would be willing to part with. It's going in 2x4 (H9281) enclosure, where I'm currently losing two slots to a mem card and a DLV11-J. I would prefer the -BF version, so I can run either my 11/23 or the 11/73 processor card in there, but the -A version will do in a pinch. Boot ROM's would also be nice, but not a hard requirement... Please let me know off-list. I am in the Pacific Northwest if that makes a difference to anyone... cheers -- alex

ISO: VAXBI hardware

by derschjo＠gmail.com

Hi all -- I have a VAX 8250 I'm bringing up and I'd like to track down an Ethernet adapter, this would be the T1034 (DEBNT). There are a few on eBay, but none include the cabling and bulkhead, which would be nice to have. I'm also looking for a T1010 (BI to Unibus adapter), as the one in my system is shot (and given the lack of documentation, I doubt I'm going to be able to fix it). Also -- any suggestions for mass storage? I have a KDB50 (T1002, T1003 set), but SDI drives are getting harder to find. I assume VAXBI SCSI adapters are even more scarce than their Unibus counterparts.... Thanks as always, Josh

DEC 3000 Model 400 Alpha Workstation

by rlloken＠telus.net

Gentlemen, I was rooting through the morgue this morning looking for a cable to revive my AlphaServer 4100 when I stumbled over my long moribund DEC 3000. This machine was retired because some of the memory failed and, although it is too large and heavy to ship, there are a lot of parts and accessories that may be of use including the strange little cable that had a connector block for the mouse and keyboard and an adaptor that I obtained from DEC which allows you to use a VGA monitor instead of the original Trinitron with its array of BNC cables. I also have an array of documentation and (good grief!) the original mouse. Anybody want any DEC 3000 parts? Or a couple of ES45 CPU cards? I have two those also. -- Richard Loken VE6BSV, Systems Programmer - VMS : "...underneath those Athabasca University : tuques we wear, our Athabasca, Alberta Canada : heads are naked!" ** rlloken at telus.net ** : - Arthur Black

Third release of the HP 3000 Series III simulator

by jdbryan＠acm.org

The third release of the HP 3000 Series III simulator is now available from the Computer History Simulation Project (SIMH) site: https://github.com/simh/simh This release adds the cold dump facility. Entering the DUMP command simulates pressing the ENABLE and DUMP front panel buttons. The contents of main memory are written to an attached magnetic tape in a format suitable for analyzing with the DPAN4 program provided with MPE. The new SET CPU DUMPDEV and SET CPU DUMPCTL options specify the default device number and control byte for the dump. Also, the user may simulate a system power loss with the POWER FAIL command and resume powered operation with the POWER RESTORE command. The SET CPU ARS/NOARS command determines whether or not MPE automatically restarts when power is restored. The full set of new features is listed in the release notes that accompany the simulator source files. In addition, an updated HP 3000 Simulator User's Guide that covers the new commands is provided in Microsoft Word format with the source download and also as a PDF file at: http://alum.mit.edu/www/jdbryan/hp3000_doc.pdf The preconfigured MPE-V/R disc image available from Bitsavers: http://www.bitsavers.org/bits/HP/HP_3000/ ...was not changed for this release. -- Dave

Need help: DSD-440 with unresponsive formatter/control board

by jrw＠lolqb.us

So the DSD-440 I got at VCF is completely unresponsive. All of the LEDs are on and never go out, which is bizarre - they are supposed to go out in 1/10 of a second after power on. I tried disconnecting everything but power to the card, and it still lights all LEDs. No jumpers that I could find are in the wrong spot, but many are seemingly undocumented ( I looked in both the 1981 user manual and 1984 service manual on Bitsavers). The drive just spins and does nothing else. Altering the switches on the control board do nothing to change the state of the LEDs. I measured voltages at the power supply, and they seem to be within spec according to the manual. Are there any other things I can try before I start digging into things on a component level?

Value of 7-track TU10

VCFMW 11

by jwest＠classiccmp.org

I just wanted to say a huge thanks to Jason and crew for putting on an incredible event last weekend. Last year was fantastic, and this year the bar was raised again in every area. To my eye, attendance was up this year yet again. There was plenty of rich toasty mini goodness, including a Prime 5300 and a Vax 6000 - and a bevy of pdp8 and pdp11 displays. The touch screen 11/70? Front panel connected to emulation was awesome! Someone was displaying some of Rod's front panels. incredible work Rod! The auction had far more goodies this year, including plenty of "big iron" that I'm sure is getting new blood into the hobby. The speakers also took things up a notch, I can't wait to see the roster for next year. I was pretty focused on Dennis's Prime the whole show, so I didn't get to really go around to every exhibit. I'm sure I missed some quality displays. I saw new people actively getting into the hobby, and I noticed quite a few listmembers and irc #classiccmp peeps that had never been to vcfmw before showed up this year. The larger space (and other amenities) over the previous venue were fully used. We may need even more space next year. It was an incredible show, of course I will be there next year, and hats off to Jason for all the hard work he put in to making it a success. Best, J
