Maybe somebody can clarify something for me. I had an 3100/M38
a few years ago and had to buy a disk for it. At the time I
bought a Quantum 210 MB drive. In order to use it with VMS
I had to get a special utility that I ran from my PC with the
drive and had to turn off the "Write-Preallocation" feature
off on the drive.
Is this strictly a VMS thing?
Is anyone interested in acquiring this rack mount communications
controller in new condition with manual and disks. A very casual
reading of the manual suggests that it is intended to provide
access to IBM and compatible machines including Systems 360/370/3
as well as 4300, 8100, system 36 and AS/400.
Communications protocols include Synchronous, SDLC, SNA, BISYNC,
X.25, and 3270 Emulation.
I would like to get at least $20 plus 1.2 x shipping for it, else
I will strip it and send the metal off for recycling. In any
event, it is gone by the end of March!

I am still trying to track down the Motorola structured assembler for
68000. I found another lead in a 1983 Motorola software catalog. Motorola
had the assembler, linker, and Pascal compiler available as "Pascal source
code for the IBM 370 with Pascal VS2 on 9 track tape" (but the requirements
said "any operating system with FORTRAN").
Do any big iron folks have this?

I have a few similar drives, but I am also considering getting an Amiga
1200 just to run Deluxe Paint. Is it an easy install into a hard-disk-less
Amiga 1200?

Do any of you fellows know of a ready/reasonable source of the 44-conductor
connectors and cables used with notebook drives? I believe the spacing of
the connector pins is 2mm. I need a limited about of this stuff and a few
of the IDC connectors to be used at each end of the cable. The adapter I
have for this drive type has a typical HD power connector on it along with
an inline pc-mount connector that would also be of interest.
Any suggestions?

Good for you. I didn't want to pay the shipping and I can afford to wait
a week or two.

There's great hack running around where you take a regular 44-pin cable
that's long enough and attach a second connector immediately adjacent to
the connector on one end. You use the inner pins of the end connector
and the outer pins on the new connector to attach to the motherboard.

Since one way to view the problem is that the motherboard connector is
on the "wrong side" of the PCB (causing pin 1 to map to pin 2, etc),
couldn't you do make a cable like this...

Wouldn't that simulate having a connector on the wrong side and reverse

AFAIK, there is no ready source of 12V. Also, consider the power draw. A
laptop drive pulls 500-700mA (2,5-3.5W), a desktop drive draws closer to
9W-15W. It's even a consideration when choosing a different
CPU (ISTR the WinChip180 is rated at ~9W, most Pentia suck around 13-17W).

ObClassic: there's plenty of space on the flash disk to stick a small OS
and a variety of apps including Kermit. If you hacked the flash and disabled
the hard disk (or had a way to specify the boot order), you could bring it
up by default into a terminal program and use it as a console if it weren't
running some other app. Yes, a dumb terminal is cheaper and probably more
VT100 compliant (double-high characters spring to mind immediately), but a
real DEC terminal is not as portable.

I recently ran onto a few 2-1/2" drives of 250 MB capacity and using only 5
volts. These are Quantum drives in case it makes a difference, and claim to
use a maximum of 0.5 Amps. Are these big enough to interest you guys? I
haven't been following this particular thread, hence haven't a clue.

It depends on what you mean by required. According to the VMS FAQ
("ftp://ftp.digital.com/pub/Digital/dec-faq/OpenVMS.txt", topic VAX5,
"What system disk size limit on the MicroVAX and VAXstation 3100?"):
[...]
Systems that are affected by this limit:
o VAXstation 3100 series, all members. No PROM upgrade is available.
===========
[...]
Generally, as I understand it, the corruption results from the
firmware writing to a too-large disk, as when a crash dump file is
written. As the firmware on these machines mentions both ULTRIX and
VMS, I assume that it is comparably adept at wrapping around at the
1.07GB limit and corrupting a disk with either style file system.
Disks larger than this limit are fine as data disks. (I have a 4GB
disk in my model 38, for example.) They also work fine as system/boot
disks, until something goes wrong, and the corruption occurs. (I boot
my model 38 from a smaller, safer disk.)
