Ooh! Where can I get one of these? I have this 3/60 that I burned new ROMs
for, I have the older SunOS tape images, the 150Mb drive, a spare monitor,
an external shoebox (with several older SCSI and ESDI disks), but no keyboard.
I started to make an adapter, but got distracted. I've used this machine with
a VT220 hung off the console, so I know it mostly works. I've never booted
an OS on it, though.

Greetings everyone on both lists:
I have a lead on a microvax near Birmingham, UK. All items in good, working
condition unless marked "not checked".
I am interested in people's comments, but the person to make offers, answer
queries, etc. is Martin Poole, martin.poole(a)pgen.com
Closing date for tenders Noon (British Summer Time) 12 July 1999.
System:
Microvax 3300/3400 Computer System
32Mb MOS memory, 3*381Mb DSSI ISE, Std Kbd., Mono Term. Expansion Cab, ?"
Cartridge Tape Drive
Spare Microvax 3400 Computer System (backup m/c.) (Not checked)
Printers and peripherals:-
LA324 -AE 24 pin Dot Matrix Printer (Three off)
LA210 -A3 Letterprinter (Three off)
Oki Microline 393C 24 pin Dot Matrix Printer (Three off, of which two not
checked)
Assorted tapes and ribbons for above
The machines are now decommissioned but were in continuous use from new in 1989
till April 1999. They have always been supported by a maintenance contract,
originally with Digital but in recent years a company called ICM Team had the
contract.
There are three cabinets, all desk-side size (28" tall x 14" wide x 20" deep)
being (I think) the main CPU, the backup CPU and the expansion box.
Since I (still!) haven't signed the lease on a storage unit of my own (local
council not replying to letters), I shall probably not be bidding, but what do
people know about these machines? How fast / reliable / compatible / easy to
set up are they?
Good luck, one and all.
Philip.
PS Enquiries and offers to Martin, just in case you'd forgotten.

I think I may hve missed out on a bargain yesterday. I was walking around Surbiton, yesterday and in one of the charity shops they had a ZX81 complete with original manuals and a black and white TV for 15UKP. I left it there becuse I could not have carried the TV all the way to the car about a mile away. Perhaps I should have told them that I would give them 15 quid for the computer and they could have the TV.
If any of our UK members are nera Surbiton and would like to see if it still there then the shop is and educationaal charity, I can't remember the name. It is about opposite Sainsbury's and is the second charity on the left hand side of the road if walking up from the traffic lights towards Surbiton railway stastion.

IMSAI 8080 chassis and CPU board. Why 'chassis' rather than 'computer'?
It's missing the front panel. I had been considering rebuilding it into a
replica of an IMSAI dual-floppy sub-system, but it looks like I may have
finally tracked one of those down, so now this piece is (somewhat)
surplus.
It does have the power supply and full card cage, so there is potential.
Mayhaps someone has one of the third party 'smart' front panel boards that
they want to play with?
Any which way... I'm entertaining offers, lest I decide that I really
need the room (and $$) and offer it up to the vultures on ePay... B^}

At the time BI came out we (I then was working for a military/aerospace
contractor) were developing a portable military workstation based on a
microvax-II. We briefly considered building our own version on the VME bus
as opposed to Q-bus, when we learned that the BI-bus interface chipset was
the microVax processor set. This would have saved lots of dough and let us
use current generation hardware in place of the obsolete rubbish for which
DEC charged so much dough. Politics doomed that notion, however. The KIM
didn't have a way to float the processor's address bus, nor did it support
prioritized interrupts, both of which were a little-used "big-deal" on the
S-100. The fact that it also didn't support I/O instructions was a real
limitation, though.

That would not be terribly difficult, depending on which direction you
wanted to go. Unfortunately, the KIM didn't produce the appropriate signals
for about half the functions on the S-100. (Neither did many of the CPU's
offered for the S-100) This stood in the way of a successful commercial
product along these lines. Nevertheless, it would have been nice to buy
rather than build a memory card or controller for the KIM.

I have just played with an Apple IIe (Model A2S2128X) I was given. It is
obviously "souped up" as everything runs so _fast_. Most games are
impossible to play on it. I just tried a pinball simulation and the ball
just bounces around at 100mph! I ran a BASIC graphics extension demo and the
bits which were supposed to show "slow" drawing to the screen were real
fast, and the "fast" draw was instantaneous.
It is not hard to guess that a chip called the "ZIP CHIP Model 8000" plugged
into the lower left of the motherboard has something to do with it! I came
into microcomputers through the Commodore line, and have never known much
about Apples, and I have not accumulated enough reference material to find
something about this add-on.
Another thing with this unit is that it happily runs DOS 3.3 but any ProDos
disks are greeted with a "UNABLE TO LOAD PRODOS" banner. So it will not run
Apple Works etc.
There is also a PlusRAM II 1MB RAMCARD which is fully populated with 1MB
RAM. I suspect that card must have cost $$$ in its day. What do I need to
access this memory?Another slot holds a tiny card called a Berkely Softworks
IRQ Manager. The centre slot contains a AIIE 80col/64K Memory Expansion
card. The remaining slots are the more common Disk II Interface, Mouse
Interface and "AII Parallel Interface" cards.
Anything anyone can tell me about what makes this IIe run like it does?

Don't know if it applies to all the HPUX 9.X platforms but, I did receive
the upgrade for my 9000/840. I just filled out the online form (sorry I
forgot the URL) and they sent me a complete package. It included all the
CDs (16 of em), installation instructions, and licenses.
Very Cool!

If this is on the list, then you should also have BI bus (32-bit bus used as
the processor bus in 8200/8300 "Scorpio" class VAXen), Q-bus (16-bit bus
going back to the early 1970's), Nautilus bus (32-bit system bus for VAX 85xx
and 87/88xx machines) and XMI (eXtended Memory Interconnect) bus, the primary
path on 6xxx/7xxx VAXen.

The Netronics Elf-II bus
COSMAC VIP (1802) expansion slot?
VME (68K and old, large SPARC servers used this)
Multibus (favored of Intel, found in older Cisco products and the NCR Tower)
Microchannel
Zorro II/III (16/32-bit Bus used in Amigas)
OMNIBUS (PDP-8/e/f/m/a - lots of batches of 12-bit signals)
C-64 expansion bus \
VIC-20 expansion bus - 6502 signals and memory decode stuff, like the Apple ][
PET expansion bus /
I guess it just depends on how you are using the term "local bus". If you
mean direct access to processor signals, these should all count. Some of
these appear as a local bus in some machines (BI bus in the 8200, etc.), and
a peripheral bus in others (BI bus in 85xx/87xx/88xx/6xxx...) Same goes for
the UNIBUS (main bus in older PDP-11's (11/20, 11/05...) but one of several
busses in later models (11/70, 11/84, etc.)
