Looking over the fact that it always hangs at the same place... I think
what is happening is, it IS booted into the PC... only that 26pin
connector is for the video dongle, and without it, you just aren't seeing
the PC screen.
There should be a cable that plugs into that port. That cable will then
have an RGB video connector to go to a monitor, an RGB video connector to
go to the Mac's video out port, and a PC Joy stick port.
It looks like the card you have is just like all the others... without
that dongle, the card is useless. FINDING a dongle is next to impossible
without getting a whole new card. Some day I will have to sit down and
pinout one of my Dongles, so that I can at least make available a wiring
diagram for others to make new ones.

Apple reorganized their software archives a while back... and they made a
total mess of things. Some stuff is located in odd places, some stuff was
moved but links not updated... ugh... its a mess for anything in the old
discontinued software.

Yeah, this is only for hosting a shared folder between the Mac and PC. It
is a VERY nice feature. Basically, you assign a folder on the Mac side,
and that becomes a drive letter on the PC side... so anything in that
folder is read/write accessable from both worlds. But it needs a driver
installed on the PC before you can configure it. That driver is part of
the PC half of the installer software (I'm not sure it is available on
Apple's web site... if not, let me know, I'll send you an image of one of
my disks... although, you SHOULD be able to use the PC drivers that come
with the 1.6.4 version of the PC Setup software, and those I believe are
on Apple's site).
I would expect you to see the error you are seeing right now, as you
can't assign a drive letter until AFTER the PC is up and running
properly, and the driver is installed.
I would check with the person that gave you the mac, see if they still
have the video dongle. If they kept the old monitor, they may have left
it connected to the monitor (I have seen that done a few times... people
don't realize the dongle goes to the computer, they figure it is part of
the monitor and try to keep it). If you can't find one, let me know...
maybe I can pinout one of mine so you can build a new one (anyone have a
suggestion on the best way to pinout an odd cable? Or am I just stuck
using a continuity tester and going from pin to pin looking to see what
connects where?)

Does anyone have programming info for these? If so, I'm interested in
one or two...might wanna try to write a NetBSD device driver for them.

>IMHO, CP/M is unquestionably a direct rip-off of RT-11.
Killdal did say that DEC OSs (TOPS, OS8 and RT11)
were the inspiration. However, one place where CP/M
was not like RT-11 was the file system as CP/M did
dynamic allocation with fragmentation where RT-11
does not support fragmented files. All RT-11 files
(OS8 too) are contigious. In that respect RT-11 file
system is most identical to NS* DOS but the NS*
dos command structure and IO are must unlike
RT-11.
Internally RT-11 and CP/M are very dissimilar save for
some underlying concepts such as an overlayable
monitor, a modular resident IO subsystem and file
handler.

One of my previous employers builds industrial security and facility
management systems. A friend from the company told me the other day that a
customer's site (a jail) has some old PDP-11 equipment that they will likely
no longer need when their new system is installed. The friend said that the
jail people said there was a 11/70 there, but he wasn't certain that they
were certain.
If I'm lucky, I may get to do some, um, contract work removing the old
PDP-11. I'm sure I could quote them a very reasonable rate.

Hello,
> Nice find! I have a couple of these and ONE keyboard. It took me four
> years of serious searching to find it!
About two months ago I noticed a complete HP-85 (tapes, manuals and a 19" rack
with HP-IB equipment) at a local industial recycling facility and told this to
a friend of mine. He immediately wanted to buy this, but when I asked, it was
already sold...
So this weekend I was at a HAM market and saw some manuals with HP-85 printed
on them and underneath was the 9915a, which I didn't recognize at the moment. I
talked a bit to the guy selling it and got it for EUR 20 (about $20), which I
hope is a good price.
> AFIK this is the only keyboard around. They are EXTREMELY rare!
Am I correct in thinking that with the keyboard I can use the 9915A as a HP-
85? Or is the keyboard just a row of digital inputs which can be read out by a
basic program?
Can I do anything usefull with a HPIB terminal? Somebody on the sunrescue list
mailed me this, but then I've tried a terminal with the serial card and that
didn't work..

Aha, I also haven't gotten any tapes... Are these still obtainable somewhere?

Those schematics would be nice if you found them, I haven't tried hooking up
anything to the keyboard ports yet in fear of breaking something. The manuals I
have are:
HP-85 Owner's manual and programming guide (2x)
Printer/plotter owner's manual
I/O programming guide
HPIB installation and theory of operation manual
HPIB peripheral installation instructions
registration and warranty cards :)
