My recently acquired 11/34 has an emulex board that has no description.
It assembly number is cu1110401, it has two 2901 bitslices.
Any pointers as to what it could be ?

Hi Ray,
Ok I just pulled the card out of one of my 800s. The terminal connects
to the top center DB-25 connector on the back of the 800. Internally, all
six of those ports connect to one cable that plugs into the top of the
Monitor card. See <http://www.classiccmp.org/hp/mds-800/chas-ful.jpg>. (BTW
You do know that the CPU and FP cards need to be installed in specific
slots don't you? if not, then read
<http://www.classiccmp.org/hp/mds-800/mds-800.htm>. It details the card
order. The first two cards must be in the correct slots. If you have
emulator cards or disk drive cards remove them till you get the system
working, there's some installation specifics about them too). The toogle
switch on the Monitor card needs to be turned towards the card. On the top
RH side of the card are two LSI ICS. Directly below them are two rows of
jumpers (straps) to set the baud rate. The only one installed is the one
>from pad 25 to pad 26. I believe this cards is set for 9600 baud (or MAYBE
19200). I haven't used it in a while but it does work. I just grabbed some
terminal cables at random and the second one that I tried worked so it's
nothing specail. I use the same cable to connect to my SB-180. Down near
the bottom LH side of the card are a few more jumpers. These set the
address of the ROM. Mine has a circuit trace between ped 30 and 31. Your's
should already be set that way.
Once you get everything connected and turned on, press and release the
IRQ 1 switch to bring up the ROM monitor amd then press the space bar a few
times. You should get a display similar to
<http://www.classiccmp.org/hp/mds-800/alive.jpg>. You won't get the baud
message, that's from my terminal. You should get the copywrit message and a
dot prompt. You can enter Q to get a list of the I/O reassignments.
To boot the disk drive, first power everything up then load a disk in
drive 1, turn on the BOOT switch (top part down) then press and release IRQ
2. Once the OS loads, turn the BOOT switch down otherwise the CPU won't
register the terminal key strokes. You should get a message like that
shownn at the bottom of the picture above.

Hi Ray,
The connector and pinout are standard. The baud rate depends on the
settings of some jumpers on one of the cards (the Monitor card IIRC). I
think most of mine were set for 9600 baud when I got them. I think the
jumpers can also be set to make the port look like DTE or DCE. I'll have to
check on the jumper settings and get back to you.

Hi, I've just acquired one of these (9826) via ebay, (I remember using one 15 years ago at work).
The one thing I can't remember is whether HPL is supplied with these as standard, or whether all languages are options. (seems pretty daft to ship it without anything)
The other problem is I can't seem to find an HPL command reference/user guide anywhere.
Could you possibly help with either of these queries?

IIRC, that F-in-an-L is the logo for Littelfuse. It certainly doesn't
mean fast-blow. You probably want a slow-blow fuse for a device like
this. Why? Because in many electronic devices, there's a surge of
current for a short while, when you first switch it on. This is caused
by the capacitors charging up, and is quite normal.

There

Yes, "Q1" is a designation for a transistor, normally. And the voltage
ratings for the capacitors suggest they're close to the mains, which
implies a sitching PSU, not a linear one. The small chicklet cap is
probably an X-rated or Y-rated suppressor cap. The transformers are
probably fairly small (an inch or two on a side), yes? For a linear
supply, I'd expect one big transformer, probably mounted on something
solid; one or more small(ish) ones are typical of a switcher. Anyway,
unless this laservision player is unusual, I'd expect such a device to
have a switcher.

'Tis time to make room around here so that I can get from one end of
the storage room to the other. The following items are up for grabs
(freebee!) - first to holler, first to be served:
**Working Stuff**
Sun Monitor GDM1604-15

Sun Laser Printer QA6
Apollo CRT Mod 010700-001 (this unit has double the normal horizontal
freq.)
VAXStation 3500 - Complete unit - boots to the point where it starts
the RA70 which then makes strange noises...
**Parts are Parts**
Sun Four Disk Storage Housings PN595-3286-1 - Nice small four scsi disk
housing w/ps. No disks (2 ea)
Sparkstation 2 (2 ea) - no disk, no video
Sparkstation 10 (2 ea) - one has no disk and no video, the other no
disk, memory, video
Xerox 6993 (branded Sun model 544) - no disk, memory, video
DEC VXT2000+ missing memory card (2 ea)
VAXStation 4000-60 missing disk
Four PC cards from and Intergraph 2-1 workstation (National 32032):
memory, video i/o, i/o (scsi??), and CPU
The above items are in the Tucson, AZ area. I will ship, but you pay
the freight...
Hi Jay, I'm not sure if I'm posting to the thread or to you personally
but I wanted to pass on the following: After purchasing a huge
assortment of DEC stuff my inventory includes a bunch of H960 cabinets
and a stack of grey side panels. I would say the panels are in good to
fair condition. We are located in Melbourne, FL so anyone in need can
come by see them. I have also delivered a few on the I95 corridor. I've
been selling the panels for $20 to $25 each, and an H960 with 2 panels
is $75. I have a few back doors as well for $25 and I have blank front
panels of various sizes. If this doesn't make it to the proper thread
please let me know how to get it there.
Thanks,
Thom

Now that I've been able to rescue some apple-II based hp2000 programs
>from my old apple disks, put them in pc and load them to
hp2000 emulation, I turn my attention to my large archive of trs-80
based archives.
I took hp basic programs, downloaded them into my trs-80 (saved them as
basic code..of course it wouldn't run on the trs-80, but the trs-80
would hold the code just fine)...these are on cassette.
I know that several emulators for the trs-80 can take cassette
input..what I'm looking for is a path to get the programs loaded from
cassette
with the final destination being a pc text file which I can then easily
upload into my virtual hp-2000.
Any ideas?
thanks!

I have a pair (3 actually) of the above terminal servers - I have them
cabled up, yet the two I have connected seem not to play well together...
the remote terminal (a VT220) displays :
>XDS90L-321, Connection Not Established - Network Not Connected
The other unit is connected to a port on my 11/44, also known good, tested
and working locally to the machine. The first two green leds are on , the
led next to the MMJ ports flashes when I transmit data, but the '#' light
remains, sadly, dark.
I have used a couple of known-good 50 ohm BNC cables between them, tried
powering them down and up while connected - no joy.
I have Googled mightily - found a bunch for sale, lots of references to
them, quite a bit of really esoteric data - but no "User Manual" yet -
save for the pointer to one on a now defunct Compaq site.
So I'm wondering if anyone with some experience with these little
beasties could afford me a clue or two? All I want is a pair, one in the
"Machine Room", one in my office, and a cable (or wireless setup) between
them.
Thanks In Advance!
Cheers

Hi all,
I went to Radio Shack last night to buy a fuse for my laserdisc player.
I needed a 125v 2amp fuse. Most of the fuses I saw were rated at
250v. I bought a 250v .75amp fuse, thinking that if I up the voltage I
have to lower the amperage. The new fuse blows instantly. Am I
thinking about this incorrectly? Now, I'm thinking I was wrong since
the fuse still only has 110 voots running through it..... so do I still
need a 2 amp fuse even if it's rated for 250 volts? Can I use a 250volt
2 amp fuse safely?
I mentioned that the .75 amp 250volt fuse blows instantly..... does this
indicate that another problem exists, or would the laserdisc player pull
more than .75 amps? The player has been sitting in my living room,
hooked up, but unused for months. I have had electrical storms here of
course, but all my equipment is on a surge protector, and nothing else
has gone bad.... (amps, dvd player, tv).
