The best way to find logic analyzer manuals is test equipment manual
The DAS 9200 was not my favorite (we had moved to 16500's by then) so
spent time digging for them. I have the svc docs for the 9100, which
to get on line.
A few years ago, I bought the complete set of TEK catalogs on eBay
late 50's forward. They're in the queue to be scanned, but it's not
that can be done quickly.
Most of the material on the 4050 series is on bitsavers. I have a few
series manuals scanned but not on line yet.
A couple of weeks ago I mentioned I'd bought a Panasonic RL-H1400
handheld computer with printer/cassette interface. I've now got a second one.
This one also came with a printer, but also with something labelled
'EPROM Extender' This is a tray that the computer fits into one side of,
and the printer into the other side. Underneath there's a PCB with 8
The plastic housing was glued together, but I've got it apart without too
much damage. The PCB also contains 10 or so TTL chips (all
pin-through-hole), a voltage regulator, etc. I've not worked out the
One odd thing is that these EPROM sockets, while the type that take
EPROMs in plastic carriers (i.e. they're not normal DIL sockets), are 28
pin, not the 24 pins ones in the HHC itself.
Is this the unit that would take the SNAP development ROMs?
I also have the dual-voltage (110V/240V) mains adapter (my first machine
came with the 110V-only version). This thing (for all it has 2 fuses
inside. in nice little holders) is a royal pain to dismantle. It's
assembled with 4 system-zero tamperproof screws (designed to be
impossible to remove without the right tool), down holes too small to
take the right tool. I ended up drilling out the holes slightly (8mm I
think), then using the system-zero driver to get the screws out.
It appears (but don't blame me too much if I'm wrong) that the HHC
doesn't use the NiCd pack as a shunt regulator, there's a proper
regulator circuit on the logic PCB. In which case it should be safe to
connect the adapter with the NiCd removed or defective.
What are you asking for them?

Indeed, this is a very good site, highly recommended for HP
computer-related manuals. I did consult the CE guide you mention, but
it is totally confusing and this is the one that got me in trouble in
the first place.
This guide gives an example of the boot screen with all the on-board
peripherals. This could not be further from the truth: (a) the high
speed HP-IB controller is mutually exclusive with the SCSI controller,
and (b) the ordering of the items in this menu (and hence which keys to
press to select various options) is wrong.
Great! The former misunderstanding caused me to expect to see the SCSI
controller even when the fast HP-IB controller was connected to the
motherboard. In fact, all I had to do to get the SCSI controller to
come to life was to unplug the fast HP-IB daugherboard from the
The second misunderstanding caused me to waste my time trying to
get the machine to switch to the serial port. I did not have a VDU
for this machine, and I did not want to spend time trying to find one
just to switch to the the console to the serial port), so I was typing
the sequence blind. Since the ordering was wrong I was not actually
configuring the serial port. I was rescued by the NetBSD HP300
FAQ which gives the correct order for the probe.
Anyway, back to the SCSI problem. I tried an ancient Quantum 100Mb
drive (yes Mb, not Gb), and the machine passed its SCSI diagnostics but
failed to detect the drive. This may well be because the drive does
not contain an HPUX boot code although I am sure I did not see the drive
access light come on during the search for boot devices.
I am looking for the 4-CPU licensed version of Windows NT4 for my SGI 540
Visual Workstation. I have only the CD set that came with my 320, which is
licensed for up to 2 CPU's, and will not utilise all 4 Xeons in my 540.
Anyone have a set they'd be willing to part with, please?

It would be nice to find the TEK 4100 series documentation. Brokers
tend not to have TEK display terminal manuals. They were the last
gasp of stand-alone TEK graphics displays before workstations killed
the whole market off.
My last job before going to Apple was as the architect of AED's VME
and QBus display board set, which emulated 41xx's (and had things
like X running on-card).

the library of our research institute has copies from at least 1/1977 completely
in the shelves (they say 1/76 but looking there, the first ones were missing).
At least the three articles of the TinyAsm are there, and I could make scans of
them on demand. You can find an index of Byte at
http://www.devili.iki.fi/library/publication/10.en.html so if you have specific
articles (limited!) you're interested in I could pdf them. I won't scan everything
due to lack of time, and I won't make them publicly due to copyright concerns, but
we could talk about few articles.
Yes, the tiny assmebler was rather structured, a nice example how to write good
assembler code. Unfortunately, the Byte articles only has a hex dump - the paperbyte
book had a commented disassembly, but I lost that eventually :-(
Have you tried this with M7800 and M787 instead of M7228? I'd say if not,
try that, if yes, and if that works, then look over the DL11-W manual for
some sort of compatibility issue with the 11/45. This is just speculation,
but it's possible that you may have to use a M787 and disable the RTC on the
DL11-W or something strange like that.

I've got an IPX that I've started working on a while back, but sort of
forgot about. I've already done the NVRAM battery, messed around with
Openboot, and done a NetBSD install. I haven't done anything with it
since.... I still know very little about NetBSD, or any other Unix for
Any way..... I have this Sony GDM-1602 sitting here. It's max refresh
rate seems to much less than what the cgsix in the IPX wants to work
with. I tried specifying resolution and refresh rate in Openboot, but
it still doesn't work. Assuming I can use this monitor with the IPX, I
don't know enough to figure it out. If I flip the monitor off and on a
few times, I can see the it's getting a signal, but the characters are
sort of skewed across the screen about 3 times. Any help would be
