Hi all --
Sent this query to the Rescue list last week, no bites. Any Sun
fanatics here have any ideas? (Linux/OpenBSD appear to support it, but
I'd rather keep the OS vintage-appropriate. For some reason...)
Got myself an RDI BriteLite IPX; a "laptop" (a generous description)
based around a stock SPARCStation IPX motherboard with a very large
laptop-style enclosure around it, a 640x480 active-matrix LCD (very
pretty) and a gigantic lead-acid battery. It has a handle, so it's portable!
Anyway -- I have it up and running and I have SunOS 4.1.4 installed on a
fresh hard disk (the original drive was long gone when I got it).
Unfortunately, the LCD framebuffer is unrecognized by SunOS; it
identifies itself as cgRDI and it's a custom SBUS board that drives the
640x480 LCD.
From what I've been able to dig up this driver was packaged as "RDIlcd"
by RDI but I can't find it, of course. Anyone happen to have this
archived somewhere? Any other ideas?
Thanks,
Josh
I've had a lot of help from all over the world getting my Data General
MV/2500 up and running, so it's time to give a little back...
I am now able to provide on-line access to my operational MV/2500 DC to
individuals who make reasonable requests for it.
Currently the machine is running AOS/VS 7.70 and has little other than
the base software installed, although most of the NADGUG library
contents is available.
I am not willing to run the MV/2500 24x7, so operational times will be
by mutual agreement. I strongly suggest using DasherQ to connect.
Access is via telnet provided by a Raspberry Pi acting as a
serial-to-network gateway to real serial ports (I don't have TCP/IP on
the machine yet).
If anyone would like access to the machine please email me stating why
you would like access (even if it is just for nostalgia!) and what time
zone you are in.

Yes I was asking myself the same question, and your answers continue to help
a lot.
I think I should retrace the path of technology evolution. Start getting it
up with paper tape tests and BCS. That probably means working mostly in
assembly and getting to know the most basic level of the machine. Which is
just about what the doctor prescribed.
Then add the mag tape for which I have the tape and the cards.
I got a 7900 disk though (with cables and power supply, but no interface
cards to go with it!). I'd love to get that one going later on. Then it
would make sense to have the bigger memory to run disk based OS systems. So
7900 interface card and memory are definitely on my hunt list...
By the way I also have a punched card reader which I just restored.
Documation ML600, but the exact same model that HP re-branded I believe. Do
you know which interface cards I need to connect it to the HP-1000? I
suppose one of the 16 bit IO ones with a driver to go with it?
Sorry to keep picking your brain, but that is so much more efficient than
trying to piece it together (usually wrong at first) from an disorganized
pile of documentation!

I'd like some of the REAL monitors, such as an NEC Multisync 3, that
can do VGA *and* NTSC-rate analog RGB. At some point the monitor
companies stopped bothering to make them handle horizontal scan rates
below 30 kHz.
I recently posted reference to a page on my personal web site listing HP-1000 assets for sale. There was a flurry of interest. As of this afternoon, the last of a half-dozen boxes were shipped to the new owners of many of these items. Thank you to everyone for their interest and thank you for your patience.
Several individuals have expressed interest in acquiring more parts. The good news is that I still have items left.
The bad news is that the 256k and 128K memory boards, +True In/Out, Term, Timebase, Error Correct, FPP Arith, and FPP control cards are all gone. So consider this fair warning: If there is something else you need to restore your system or to build a reserve of spares, now is the time to grab it before it's gone, too.
The inventory sheets have been updated on my site to reflect what is left. Some items are being offered piece-by-piece, some I'd prefer to sell as a set. Details are on my site.

So much for "YMMV": jkunz and I must have had some really bad tapes back
then at the VCFe a couple of years ago. When we tried to read them (in
a TK70, I think - does that make the difference?), they slowed down the
mechanism, produced a squealing sound and stuck to the head to the point
where in some cases the tape (carrier) broke in some cases. We did clean
the head and tape guide parts with IPA several times only to get the
same problem again. I'm sure he can elaborate a bit more about the tapes
and the equipment used but I think I have it mostly correct.
So Long,
Arno
anyone know how to hook these up?
has controllers to talk to a Shibaura VMC-45 with a Tosnuc 600 control
picked it up for 50 bucks in near mint condition localy this week
and i'd like to hook it up to my laptop to back up every tape i got at this
time
Does anyone here have a spare keyboard for a Compaq Portable?

Hi list,
3 years ago, I picked up an HP 9144A QIC tape drive with HP-IB interface. It came with three 16-track QIC tape drives. I never found the time to connect it to my HP 9000-300 and realized that I will probably never make use of it, which is why I'd like to give it to some other collector's hands who is interested. I powered up the drive for 2 hours, no smoke, the fan was running as expected. Nothing else tested.
Picture of the actual three tapes which come with the drive:
http://www.digitalheritage.de/OTHER/20141223_155006_tn.JPG
I forgot to take pictures of the drive, but will do it, as soon as I can access it next week again.
In the mean time, here is another one of the tape drive (not mine):
http://www.hpmuseum.net/display_item.php?hw=257
The drive weights 9kg (20 lbs).
First come, first serve. Drive and tapes are for free. You have to pay shipping costs or come to pick it up. Location is Bonn, Germany.
Kind regards,
Pierre

I've been using my lone RL02 with my QBus systems, I'd love to be able
to use it with my 11/34 as well. (If anyone has a spare RL02 *drive*
I'd be interested as well...) I have various DEC stuff for trade, drop
me a line if you have one going spare.
Thanks!

Dave,
Super useful info again. In the meantime the machine has arrived, in very
good shape. I'll post pictures when I have time tomorrow, and a video
hopefully. I took a quick look inside to confirm
- there is a DCPC and a MEM protect card
- Memory controller is an older 2102A
- Three are three 8k 2102A memory boards
- No MEM card in slot 112
- Under the processor board there is a screwed on card, which seems to have
ROM on it. Microcode I presume, but I don't know if that's the one you were
talking about. I'll post photos to confirm
The IO cards and the paper tape reader / punch that came with it suggest
that it was configured with a paper tape reader, a paper tape punch, a mag
tape and a TTY interface. A plausible story is that this was an early
machine setup for paper tape and TTY and didn't have extended memory. The
early 2102A controller fits that picture well.
So I might be in the hunt for the cards or alternate solutions you
mentioned.

First, are you sure that the machine does not have DMS installed? It was a
very common option that became standard later on, as all versions of the RTE
operating system after RTE-II (circa 1976) required it.
Second, if the machine originally came with DMS but was stripped for resale,
then possibly only the MEM card (in slot 112) was removed. The firmware
card is screwed onto the CPU board on the underside of the machine and is
only accessible if the bottom cover is removed. So maybe it was overlooked,
and the availability of MEM cards is likely to be reasonable, as the same
card (but with different firmware) was used in the E/F-Series machines.
Third, if the machine has neither DMS part, then indeed finding an M-Series
DMS firmware card might be difficult. However, DMS firmware was also
included with the later M-Series Fast FORTRAN Processor firmware (product
number 12977B). Again, the FFP was a common option, and availability of
that card might be better than the older standalone DMS firmware card.
Fourth, if you can find a standalone MEM card, the M-Series DMS/FFP firmware
source is part of the HP 1000 Software Collection on Bitsavers, so you could
burn the required firmware PROMs and install them on a 12791A Firmware
Expansion Module card, which plugs into the I/O backplane and cables to the
CPU board. Both the FEM and the MEM were used on E/F-Series machines, so
availability should be reasonable.
Finally, the simplest HP operating system that used DMS (RTE-III) had
additional hardware requirements: a Memory Protect card, a Dual-Channel Port
Controller (i.e., DMA) card, one of several console I/O cards, a Time- Base
Generator (i.e., clock) card, and either an HP 7900A or 7905/06/20/25A hard
drive and its associated I/O interface(s). The latter may be the most
difficult and expensive part. You can avoid the hard drive and use Ansgar
Kueckes' HPDrive emulator with an HP-IB I/O card, but that requires RTE-IVB
as the minimum OS, which requires at least 96KW of memory (128KW if you want
to do anything other than boot the system :-). MP and DCPC also were
exceedingly common options, so I'd be surprised if your system didn't
contain them, unless they've been stripped out for resale.
Without DMS, you're limited to 32KW. In that, you could run (with some
additional hardware, most notably an HP hard drive) DOS-III or RTE-II.
Without a hard drive, you'd be limited to running one of several paper tape
or mag tape-based HP OSes. There are third-party OSes that run on the 1000,
but I know nothing about them.
At least software is no problem; virtually everything that HP developed for
the 2116/2100/1000 machines is available via the Bitsavers collection.

I've been brainstorming about hypothetical hardware for converting video from vintage 8-bit computers to drive modern monitors well, with support for all of the dirty tricks like color aliasing that many of them used. One of the things I would like to understand is the range of RF frequencies used by the machines that connected to ordinary televisions.
My old Color Computer used US VHF channels 3 or 4 for NTSC video. I found a reference to the ZX Spectrum using UK UHF channel 35 for PAL video.
What other channels were used all over the world by 8-bit home computers (and video games, too, I suppose), and which TV standards were used with them?
Hello Folks,
with a bunch of HP 9000 equipment, I received a HP-PB "802.3 10Mbps LAN"
card that was missing the 10base2 BNC connector and the SOT23 SMD part
directly behind it. No idea why and by whom they were removed. A BNC
socket was easily found in one of my parts bins, but what about the
SMD component? My first idea was this might just be some sort of
transient protection device (I've seen a really old ISA NIC fitted with
a neon bulb next to the BNC for that purpose!) but there probably is a
bit more to it, as pin 1 connects to BNC Center and to pin 7 on the PHY
(U18, NatSemi SS9130AP also HP house-marked as 1820-7730), pin 2 is BNC
shield/ground *and pin 3 goes to pin 5 on the PHY*.
Unfortunately I was not able to find a datasheet for the PHY that would
probably give an example circuit - can anyone please either point me to
that or, if they have an example of that card available, look up the
marking of that SOT23 device for me?
Card would be for my HP9000-K100 PA-RISC, for which I'm also looking
for one of the graphic options. One keeps popping up in the US 'bay
but the (commercial) seller wants real money for it - add S&H to old
europe and it's waaay out of my confortable range.
Thanks in advance,
Arno
The Intel AFN-00188B Datasheets for 8041A/8741A specify that EA max is
24.5V. The verify mode for "PROM/ROM" holds EA high at 23V.
The 8048/8748 Datasheets say EA is 32V for 8748 Verify but need only be
+12V for 8048.

I mentioned earlier I had an ebay auction running for an 11/44 and there
were questions about the interior card cage. I uploaded new pics. Here is

M7819
M7814
M7258

M7297 / M7298

When I posted the original listing I assumed incorrectly that all of the
computer cards were in the 11/44 and the internal cage was for the few
backup tape drive interface connectors. Apparently I was way off. The new
pics help explain what the 11/44 was doing before being taken out of
service..

Like what? Like most people on this list, I'm far enough away that I can't
just drive over (especially on such little notice), but if there's something
good there, perhaps a local DEC collector can help, or I could pay someone to
go get it. But without having _some_ idea what's there.... Any cables? (Those
seem to usually be in short supply.) Any chance of some pictures, if you have
no idea what's what?

8088 computers, one has 2 floppies, 1 has 1 floppy and 1 hdd.
Both fully tested and functional. No keyboards now, but there is an
original IBM mono monitor, and the printer.
I do NOT want to ship; these will not survive UPS very well.
We are about 1 hour from San Antonio.
Make a good offer, take them home.
Lots of software to go with these.
Must be gone before Monday.
I will be at the warehouse all weekend.
Also 2 NIB 14" amber VGA monitors.

WikiP under the "PDP-10" subject claims that Don Daglow wrote the first
computer baseball game in 1971.
I don't think that this is accurate; do any old CDC-ers out there
remember the BAT PP program on every CE's MACE deadstart tape? I
believe that it preceded Daglow's game by a couple of years.
I know this may chafe some of the DECfans out there, but I think the
claim is simply not accurate.
