My /37 has all five slots filled. The CPU, 2 HP-IB cards, memory, and the
serial card with 6 ports.
When I had the case open, I noticed a bus connector just behind the front
panel. There is a cutout in the chassis above the connector where a ribbon
cable could be passed to another backplane. I guess you could stack another
chassis on top of this one.

I retract my assertion that a WinChip does some kind of integrated video.
Somewhere along the line of <$400 machines, I because misinformed/confused.
There is some form of recognized video chip on the iOpener, but it _does_
use main memory as video RAM.

A "WinChip 180" - kinda like a P-180 with extra stuff onboard to implement
video on the CPU and use main memory as video memory (kinda like what the
Amiga does, but not exactly). It's its own thing designed to reduce part
count and manufacturing cost.
> Tell me more about this, is the LCD part of it??
Yes. The idea is that you buy their box for cheap and give them $250+
per year in ISP fees, subsidizing the hardware. I'm going to go look
at one at CC at lunch and see if you buy the unit over the counter and
_then_ sign up when you bring the box home. I expect that they charge
$199 at CC and you get $100 off your usage time. Even so, $200 for an
integrated box that is reconfigurable isn't bad. I bought a proprietary
flat-panel 486 with PCMCIA and one ISA slot for about that (16Mb RAM, 500Mb
disk, no floppy but an external floppy connector). This is _much_ more
powereful except for the lack of expandability and the lack of a built-in
network jack. All I need right now is a source of used DE-620 pocket
Ethernet adapters to charge on ahead.

For the uninitiated, I think I must at this point issue a warning:
THERE ARE TWO SERIAL PORTS ON THE COMMODORE 64.
One is a (can't remember how many. 5+/-1)-pin DIN connector. This is
Commodore's serial version of GPIB, and is where disk drives and things go.
The other is the RS232. I can't remember whether that's a separate connector,
or simply pins on the user port.
I would guess the printer goes in the same port as the disk drive, if it is one
of Commodore's own-badged Epson things. IIRC you daisy chain them - one cable
64 - Disk drive, next cable disk drive - printer, etc.
Philip.

Mixing high- and low-speed devices on the same HP-IB channel is not
recommended.
And adding I/O to the /37 is hard -- there are five slots, and between
CPU, memory, ATP/M (serial I/O), and GIC (HP-IB) you're already using
at least four. The fifth slot is often occupied by more memory or
something else (e.g. an INP or LANIC). I think there's a way to add a
second card cage to a /37 but I'm not sure I've ever seen that done.
So if you really want a printer, you might want to think about a
serial printer plugged into one of the ATP ports. I used to run a
2563A that way in the mid-1980s; 9600 bps did OK at keeping up with
a 300 LPM printer that was used to print COBOL listings.

I'm glad someone got it. Joe told me about it too but I couldn't see
shipping it all the way to California -- already got two /37s and
don't have anywhere to put a 7937-sized disc right now.

Hi gang,
Went with Joe Rigdon last weekend and picked up a HP 3000/37 that he had
spotted. The unit was mounted in a short cabinet with several 670H drives.
It had been sitting partially covered in a scrap dealers yard in the Orlando
area. Thankfully, it's not the rainy season so, it was still in pretty good
shape.
When I got it home and opened the computer up, it really wasn't that dirty
inside. I just dusted the boards off, checked the connectors for corrosion,
and reassembled it. The switch on the front panel was gummed-up and stuck in
the off position. I broke it trying to work it loose and had to do some
microsurgery to get it working again.
I opened up each of the 670H drive cabinets, dusted them out, and
reassembled. When plugged in, everyone of them gives a green light. A couple
of them sounded a little funky during their first spin-up but, they all seem
to be working now. Obviously, they had been sitting for a long time and were
reluctant about going back to work. I can relate to that :-)
All in all, I got (8) 670H, (6) 7963B, and a 7936 (I think that's correct)
drive. The 7963B can support multiple drives in the same cabinet but, these
only had one drive each. The 7936 is a big sucker. Similar to the 7937
"Eagle" drives. I've previously had trouble with Eagle drives so, I haven't
even tried to power that one up, yet. These are 8" belt-driven monsters that
are sensitive to shock and inactivity. The belts get all gooey and are a
pain in the butt to clean. Last time I tackled one of these, I strained my
back trying to put it back in the cabinet. That particular drive crashed
within a week and really pissed me off.
I mounted 3 of the 670H drives in the cabinet with the 3000, connected my
tape drive, and powered everything up. After much dinking, I was finally
able to install the OS from the MPE FOS tapes. I'm still a rooky at MPE but,
after threee days of tinkering, I got it to work... YIPEE!!!
Let me tell ya, over the last few days, I have learned a LOT about
installing that OS.
Still having trouble configuring the system with a line printer. Not sure if
the problem is with the printer, the configuration, or me (naw couldn't be).
When I connect my HPIB printer, the system has trouble finding other devices
on that chain. That printer was working with my /42 but, it was on a port
all by itsself. The /37 doesn't have as many I/O ports as the /42 so, my
options are considerably more limited.
Anyway, I finally have a "Classic 3000" that doesn't double as a space
heater. Both me and my air-conditioner are happy. Many thanks to Joe for
turning me on to this *great* find.
See Ya,

Hello all, I picked up a nice DEC cabinet and nestled inside of it was a
DEC Channel server which is apparently a MicroVAX II, 8MB of RAM, and a
four or five board set that connects to an IBM "channel". Does anyone have
any interest in the channel interface and the cab kit? (I've got designs on
the BA23 and the rack which is what I wanted in the first place.

What you need is a 15-24 VDC supply which can put out one amp, center
negative.
The 2068 is a very nice machine, but was abandoned when Timex ceased
production. Very little software was produced for it, but with a Spectrum
emulator cartridge you will have access to over 10,000 programs which are
posted on the 'net. Disk drive interfaces are still available -- brand new
-- as well as centronics i/fs and even EPROM burners, if you want to take it
that far. I also have a speech synth and tape drives attached to mine.
If you can get the machine for under $100, and it works, and you don't mind
spending a little more time and $$ chasing down some extra hardware for it,
you can put together a pretty cool 8 bit system with one of these. I use
mine every day.
If you need some more help let me know off list

They are the same HDA. Different board.

RZ is a scsi designation. I believe the RF35 and the RZ35 share a
common HDA; only the logic board is different.
