Once, I got some self-adhesive labels wrapped around the drum on a
Canon, and with nothing to lose, used cotton pads and iso-propyl
alcohol to remove them. After a few sheets, it was as good as new.

All the IIIs I've seen had JetDirect cards (they all came from
netwroked environments). They only work as single-protocol in a III,
but just about any JetDirect MIO card should work, as far as I
remember. Look for J2250A, J2550B, J2552A or J2552B (that's what are
in my 4s, 5s, and 1600).

I don't recall that there were many docs other than the one page sales
brochure and the schematics for the BB I.

I checked and what I have is for the BB II
I think the original Xerox 820 board was VERY similar to the BB I though
so those docs may help.

I have the docs scanned, will try to get them on line for you. I may
have BB I docs as well.
I have written a VAX test program that probes various intricate aspects of the
VAX that is running on in the areas that are defined as implementation-dependent
or UNPREDICTABLE by VARM. It runs in user mode under Berkeley UNIX. Any flavor
of Berkeley VAX UNIX should do, including Ultrix, although I can't make any
guarantees about NetBSD as it has strayed so far from Berkeley UNIX that it has
no business running on a VAX really. So if you have always wondered how exactly
does your VAX handle something that VARM lists as UNPREDICTABLE, and you have
Berkeley UNIX running, this program will tell you.
The source is available on my FTP site at:
ifctfvax.Harhan.ORG:/pub/VAX/vaxtest/vaxtest-1.0.tar.Z
I have run it on my CVAXen and the output is in the same directory on the FTP
site in file results.cvax. I will run it on a MicroVAX II in a couple of weeks
(when I put one together for testing) and on Rigel in a few months (when I port
4.3BSD-Quasijarus to it).
I have no other VAX implementations to test on, and I solicit input from the
community. If you have a VAX on which you can run this program (i.e., one that
runs any version of Berkeley UNIX or Ultrix), please run it and post or send me
the output. I need to determine the characteristics and quirks of as many VAX
implementations as possible. (If you are wondering why, this has to do with my
project of designing and building a new VAX. Yes, I know that I simply need to
follow the VAX spec and strictly speaking I don't need to look at any other
implementations, but there is also the real world.)

Care to share? :-)
I could use an 11/23 with an RL02...

I want one. I can use a PCI, ISA, EISA, MCA (PS/2 or RS/6k), NuBus
or QBus adapter. The main requirement is that hardware + software be
able to low-level format disks to RX02.
I have a YE Data YD-180 drive from an AS/400 that looks brand new.
According to a couple of comp.os.cpm posts, it's a standard interface
DSDD 1.2MB drive with DC24V/DC5V input. So far so good, and I have a
couple of older ISA floppy controllers that should talk to it (right?),
but I need a controller cable and power pinout for it. For that
matter, between the DE9 power connector on the IBM sled and the power
input on the drive itself, there's a small PDB that looks like it might
be a transformer or step-down. Anybody know what voltage the AS/400
feeds it? Anybody happen to have an 8" enclosure and PSU they don't
want?
And, most importantly, that drive *will* format a disk as IBM 3740
format, right?
I have 3 computers with RX02 drives, about 300 bulk-erased floppies,
and no way to make the floppies useful in those drives*, and that's
starting to p_ss me off.
* a couple of places I can trade degaussed disks for formatted at
varying ratios, and that's probably the cheapest way to go, but that's
hardly the point, right?
