Yes and you want one as they store 95 meg and it's a sorta default
smallvax tape. The TK50z-fa is a second box the same size as the one you
have. If you can find a external storage box (yep, another bix just like
that one) you have the full storage boat.

Also check out www.decus.org as you can get a license for VMS free. The
real trick is media as Montgar.com has the CDROM with VMS5.4 through V6.1
and a bunch of other stuff for 30$. Usually you can get someone to crack
the cdrom (it's DEC VMS files not PC compatable) to TK50. The alternate
is if someone has a VS2000 or MicrovaxII they can put the OS directly on
the rd54 and you can plug it in. Ultrix can often be found on old
machines as well if your into unix.

No, but the other way round (CompacTape/TK50 in a CompacTapeII/TK70 drive)
works.

Hi Allison:
May I have few blank disks from you too...?? I live in Hong Kong, and I
discover that I never can find 8" disks in my location! :( If so, I would
pay the shipping... :)

Just to be different, I accidentally sent this to Hans instead of the

Opto mechanics? Fine. That is, fine if you want your data to be

:-) IIRC, marked Livres, Solz, and Deniers. What's Solz an
abbreviation of? Solides? I thought shillings were Sous!
(off topic) I've always thought the single European currency should be
called a Pound because there's a word for it in almost all European
languages - Pfund, Livre, Lira, Peso(?) etc. Dollar would do as well, I
suppose (Thaler?). Or even Ecu (Escudo?). But Euro?!?!?!?

What does "HRK" mean? I apologise for taking it as your initials - our

< Saturday at the local swapmeet, I picked up a MicroVAX 2000. It is a
< neat little package, but now that I have it what can I do with it? And
< how do I do it?
IT's a vax and runs VMS(fits on a RD53 or 54), Ultrix(fits on rd53 or 54)
and sorta runs NETBSD(?).
If you put a terminal on the DB9 (ground pin 8 to 9) it will use a
standard terminal (9600, 8,n,1). The Test 50 command will display ram
installed and other data about the system.
VMS and ultrix runs fairly well in 4 or more meg of ram NetBSD wants 8
or more, 14mb is max.
< This one is a Model 625NT-AA, and comes without harddisk. It appears
IT has a hard and a floppy controller on the board (the 60 pin connector).
The biggest drive it knows is the RD54 (maxtor 2990) at 159mb. It can
also format hard disks and DEC floppies rx50 <400kb dual 5.25> or RX33
<1.2mb, 5.25>.

The 318mb of local disk is 2 RD54s.
The 50 pin internal connecter is indeed SCSI... but the only device usable
is an oddball version of the TK50 tape that has the ODD scsi
bridge board. Reason for oddball, BOOT ROMS do not talk std SCSI
nor do they boot anything other than Eithernet (BNC), Floppy, HARD disk
or TK50 tape on the scsi BUS. It will not boot a SCSI disk. It can use
a SCSI disk IF you supply your own driver.

25 pin is modem. 15 pin is CRT/keyboard/mouse, 9pin is serial printer
or console. The MMJ adaptor bring out the serial printer, mouse and
keyboard lines to RS423 serial lines for terminals (ala dec vt320).
That MMJ adaptor is removeable (two screws). Network is on the AUI or
BNC connector and is eithernet (10base2).
They are common as house flies and as small vaxen go pretty useful and fun
to run as they really don't use much power.

One of our fellow collectors 'down under' is apparently seeking a

If you can help, please contact him directly.

I am after a used vaxstation 3100 or 4000 model.
Must be working. Also TLZ06 DAT drive wanted.
Has anyone got one for sale in Sydney, Australia area.

Gerhard Moeller has hacked together a SCSI driver for the beast. You'll
still need an MFM drive to boot from, though. He posts fairly frequently
on comp.sys.dec or comp.os.vms, so it shouldn't be difficult to track
him down with dejanews.

Unless, of course, you install something like MicroVMS 4.5, which was
current when the thing came out. I've installed 7.1 on an 40MB drive,
but it was painful and it occasionally spontaneously crashes. Using
Gerhard's driver, I have a nice little package containing a 40MB drive
and a TZ30 tape drive to take on travel. I did have to do some metalwork
hacking to get the TZ30 in; there's a cable that wanders around outside
the 5.25" form factor.

Well, technically, the format itself is compatible. The 2000 just adds
some extra information to control bad block replacement. The PC doesn't
know about the extra information and, consequently, doesn't add it.

The SLM804 Laser Printer was Tramiel's attempt at a laser-for-the-masses
back when a Laser Printer was a multi-thousand-dollar item. It had no
on-board intelligence or memory; it used the ST's CPU/RAM. Sounds like
what you have there is the controller interface. (Plugs into the ACSI port
on one end and the printer on the other.)
P.S., anyone want an SLM804 in need of some repair?

Hmm, IMSAI's didn't have ROMs (or PALs and FPGAs, programmable logic had
yet to be invented), unless you added them in yourself. As for checking
the power supply, an IMSAI was extremely easy to eyeball...huge
transformer, diodes, and beer can size capacitors. One problem I never
had with IMSAIs was in the power supply, the design was right out of
Electronics 101, nothing beats a big lump of iron for simplicity. Now
rust might be a problem...
Actually, the only real problem I've ever found with S-100s is the bus
connectors wearing out. I have an old Ithaca Intersystems DPS-1 in need
of a replacement Morrow motherboard. Well, not really in a hurry to fix
it, all the Ithaca boards have been in the IMSAI for the last 10 years,
but I hate to throw out the DPS-1 since it had the neat front panel with
the PDP style toggle switches.
