True... to a point there are SCSI drivers for the MV2000 for VMS as there
is a SCSI bus in it!
To be exacting the SCSI bus in complete but the boot roms will only
recognize the oddball TK50. There is a fellow that developed a SCSI drive
so VMS can also talk to SCSI drives.
Also the MFM controller will talk to RX33 floppy, and more than one RDxx.
ALL MV/VS3100s are SCSI some may have the TLZ30 tape or RX23 floppy in them.

Yes, the first 3100's had MFM controllers, and half-height MFM drives
(RD31, RD32) in them. They also had a 34-pin floppy interface to a
non-SCSI RX23. Then came models that had *both* MFM and SCSI interfaces.
The latest ones had two SCSI interfaces, and used a SCSI-fied RX23 in
them.

True, the RX23 doesn't have a lot of use. You can't even (officially)
build a standalone backup kit on it.

Rather than spinning this on this list. Why not check out the 2600 web
sight. I don't know what it is, maybe www.2600.com.
They'll know all these answers and it will be on topic for them...

<So. What's the *smallest* vax-11 (or other machine) that'll run vms?
<Wait...
Depending on what you mean by smallest (most minimal archetecture |
physically smallest) the answer would be MicrovaxI and MV2000.
<Actually, if someone wants to save me before heading down this *enticing*

Wouldn't mind having that one! or the vax books. ;)

I made a full list and here it is (with a picture of the system):
F6470A (2) - tape cartridge system, 16 carts @ 400MB each
M770 - main supercomputer(s) (looks like 4 cabinets), at least 100MB RAM,
MSP/EX , and XSP operating system (other operating systems as well). No idea
of speed, bus width, anything else... I do know both mainframes) were
connected together through a high speed data channel.
There seems to be some SUN 4-490 front-end computers. No idea on any more
than that.-- they look nice.
F1751E (2 of them) - 60? tapes X 400MB = huge tape cartridge unit. Total
storage ????
There are also some memory expanders?? a high speed 2000?LPM printer, disk
RAID arrays (5GB each).
I have found a few sites still using this supercomputer, one as a
meteorological satellite data processing system, an engineering lab,....
Here is a picture of what the system looks like (I will put up real pictures
soon):
http://www.pdp8.com/fujitsu.gif
The vax 6000 has:
RA81 - 3 units
RA81,RA82,RA82
TA81,TU81E
HSC 50-AA
Vax 6000-610
SA600
HSC-50
and....
1 pallet of power cords and system cables.
1 Omnigraphic Recorder. - 11 X 17" XY chart recorder. 2000CE
Well, it's sort of 'saved' already; this machine is sitting in my garage.
But, I'm planning a move, and it HAS to go sometime sooner rather than
later. And if it comes to it, 'later' might mean that it goes to the TIP.
That would be a shame. Unit looks in good condition, and had the heads
professionally parked before I grabbed it. Has a floppy drive (RD-50?) and
some tapes, too. I've never tried powering it.
Unit is in Sydney (Australia), and I'm sure hoping somebody wants it. I'd
feel rather bad seeing it junked.
Totally free, of course.

Vaxen have not been my gig but today I found several books. VAX
Architecture Reference Manual,VAXclusters, Computer Programming and
Architecture: The VAX-11, A Gentle Introduction to the VAX System, The VAX
Book, VAX/VMS Internals and Data Structures, and Introduction toVAX/VMS.
This can only mean one thing. ;)
Actually, I've started reading VAX/VMS Internals and Data Structures. Now I
know what a real operating system is. Alas.
So. What's the *smallest* vax-11 (or other machine) that'll run vms?
Wait...

The smallest machine that'll run VMS is the "Tadpole" laptop, an Alpha.
You won't find them for free in junkpiles yet, at least! They're highly
in demand by those who want to demo Alpha/VMS software at trade shows,
customer sites, etc.

Hi to all you DEC-heads!
I recently picked up a big pile of DEC manuals. One of the things that I
found among them is a manual for IGOR (Interactive Graphic Operating
Resource) Internal Operations. It was published by Interactive Graphic
Systems in 1981 and is marked "Company Confidental". This is almost
certainly for use on a VAX. Does anyone know weather IGS or IGOR is still
around? Any thoughts about weather I should destroy this manual, keep it,
sell it or ?

If the drive is "intelligent" enough to perform writes, i.e. if it has a
local data buffer, then it's likely to have a master oscillator. Since it
has adjustments for "window" (probably related to FM clock recovery) and
"gap" probably limiting the write-turn-on/off gap lengths, i.e. the capture
window, allowing it to determine when it failed to "see" and address mark,
I'd suspect that those have gotten tweaked out.
