For those who remember GopherVR, this will need no introduction; it is a
virtual reality interface to Gopherspace. I have managed to get it working
again on Mac OS X, and it should build other places. There is a long way to
go, but it is now stable and does work even though it is still not finished.
A pre-built binary is available for Mac OS X 10.4+, and source for everyone
else.

Hello All,
Everyone recovered from X-Mas yet :)
Maybe one of you can help me, I need an M908 paddle board.
Let me know off list and maybe we can come to an agreement.
Thanks,
Ed

Old DEC Power Control 861C Hi,
looks like I am not getting the posting in my e-mail but my messages do get
posted.
I found this replyto my previous message by Tony Duell
<cctalk%40classiccmp.org?Subject=Re%3A%20Old%20DEC%20Power%20Control%20861C&In-Reply-To=%3Cm1NM4jS-000J3uC%40p850ug1%3E>in
the archives.
To follow-up, the 861C emits a crackling noise for the first few seconds (20
or so) and then I can hear a relay chattering (very noisy!).
Also the light on the front panel is flashing continuously (maybe that's
normal.)

The DEC power cotnrollers are _very_ simple inside, and you don't really
need tjhe printsets to repair them.
I am not sure I understand the fault description. In particular, what
sort of noise (hum, chattering relay?). And what do you mean by 'trigger
off'. Do you mean the contactor drops out, or the breaker trips, or what?
Let me know exactly what happens and I might be able to help.

Ansgar Kueckes has released a new version of his "HPDrive" disc emulator
that works with HP 64000 logic development stations and HP 1000 MEF-series
minicomputers, in addition to the HP 9845. The emulator is hosted on a
Windows PC with a GPIB interface card and appears to the target system to
be any of a selection of HP-IB floppy, hard, or cartridge tape drives that
use the Amigo or CS/80 protocols.
Drives that are not supported natively may be added via a configuration
file if the drive parameters (Amigo) or Describe information (CS/80) is
supplied.
The project page is here:
http://www.hp9845.net/9845/projects/hpdrive/
The emulator has not been tested with the HP 1000 A/L-series, nor with the
HP 3000, but the disc emulations are reasonably thorough and may well work
with these systems.
My thanks to Michel Bissonnette, Al Kossow, Frank McConnell, and Jay West
for lending hardware for HPDrive development and testing.

The HP 100LX/200LX/1000CX/OG700LX use the "Hornet" chip, which contains an 80C186 along with I/O, display and other modules. There is info on this chip (block diagram, pinout) at http://www.daniel-hertrich.de/en/knowledgebase/hplx/hornet ?

Actually, I was thinking of the HP 200LX, sorry. That *does* have a 80186
for sure.

Does anyone have a stash of them? I have one fo them and it is getting old
burning it, testing the device, erasing it, and burning different code into
it, lather ? rinse ? repeat.
Hi. Just wondering if you ever figured out how to chemically lift
images from faded dittos. I have the same problem with a personal
document that you did with the Mark-8 Newsletter. Thanks. --Dawn Lausa
I have been trying for some time to repair the 2.5V supply on an 11/750, without success. The symptoms are loud squealing which changes back and forth in pitch (in fact it sounds a bit like RTTY, only over a couple of pitches), OVERCURRENT and REG FAIL indicators on the status panel on the back of the machine.
All the boards are pulled from the backplane and I?m using dummy loads on the supply. There?s no evidence of shorts on the chassis or on any of the supply outputs. I?m testing with the voltage sense wiring in place.
The output electrolytics have been replaced on the 2 regulator boards and the big electrolytics on the primary side check out OK. I?ve measured 300V DC across the switching transistors on the primary side. I?ve not detected any problems with the electrolytics on the 30V supply and 2.5V supply but I have ordered replacements just to be on the safe side. I?ve checked over all the diodes and transistors with the Huntron tracker with no obvious evidence of any failures.
So far all I?ve really been able to establish is that there?s no output on the ?secondary? side of the supply, that is, the 30V supply which drives the +/-5VB and 12V regulators, and the 2.5V main output of the supply. I think the REG FAIL lamp is a red herring because without the 30V supply active, REG FAIL would have to be lit if I understand the schematic correctly.
I?m posting on the off-chance that someone has had this problem and has dealt with it. I?ve been looking at this on and off since July but haven?t made any headway.
Thanks for any suggestions the group may be able to offer. By the way, the story of the machine and work done to date is at http://comley.us/browse.php?&action=show&artefactID=1051
