Yep, count the chips to determine the capacity.

If it *is* a "RLV12 clone", it doesn't hook to s standard RL01/RL02 drive;
it would make a MFM (or SASI or SMD or ...) drive look like a RL01 or
RL02 to the system.
If you can describe the card more fully (connectors? Big chips?) we'll
do a better job of telling you exactly what it is. Sigma had the habit
of starting many (not all!) of their clone-cards with R's (most of the
others are S's), thus the confusion between RLV11 and DLV11.

It tends to be a loose Agnes chip. In the A500, C= later shipped a metal
clip to attempt to hold it together in shipping. While the machine is
open, check the integrity of the Agnus socket (the big square one in the
middle of the board). If a previous owner tried to remove the Fat Agnes
without a PLCC extractor, it's possible that they goobered up the socket.
Mostly, as long as there isn't a vertical crack from the top of a corner
down towards the PCB, you are probably OK for this problem.
If no crack, press on the Fat Agnes to re-seat it. It might click as it
seats.

Guys:
Does anyone out there own a *working* Xerox 6085?
I have a potentially interesting experiment in need
of a suitable volunteer.
Please reply via private e-mail.
Thanx.

So why did Kaypro or, Non-Linear Systems as it really was I understand, go
out of business anyway.
I had gotten busy with other endeavers and when I looked about 1989 or 1990
or so, Kaypro was gone.
It seemed as if they had enjoyed a good reputation. What exactly went wrong
if anybody knows?

Been a little while since I got a "new" computer. One of the neighbors was
getting rid of some stuff from their basement, which included two
computers. Luckily they now I'm a computer freak and told me I could have
whatever I wanted. So, now I have an Amiga 500 with p/s, A520 video adaptor
and what looks like a printer cable. No disks :-(, but it did have the
original box(wow! a 7MHz 68000 and 512K RAM!!!). Also got a C64 with 1541
drive, two joysticks and probably 50-70 disks(haven't gotten around to
counting. But hey, Pac-Man is in there!). The C64 seems to be working just
fine(not sure about the drive yet), but the Amiga isn't. When I finally
figured out how the A520 worked, all I could get on my Apple composite
monitor was a green screen with a blank area at the top(looked kinfa like
the video is off a bit inside the monitor, which is partially true but it's
not THAT bad... just some hidden text on the edge usually) which blinks
maybe every 10-15 seconds or so. No sounds, no text, not really any video
at all. The power light is kinda flashing, maybe once every second or
two(haven't timed it yet). Any ideas on what's wrong? I'll hold off on the
how do I use it questions until after I finish raiding the local library of
the computer books, but feel free to send me any tips and tricks for these
systems...

Guys:
I asked some time ago if there was anyone interested
in MINC-11 hardware. If you guys are still out there,
please contact me via private E-Mail.
Thanks.

OK, I've got basically everything easy to come up with any kind of ID,
inventoried, a bunch of it's pretty much unmarked, so will take some
looking. Does anyone know what any of this is?
DCW-RL02 MTI MLV11M-3
MLSi-LP11 MDB SYSTEMS, INC
MZV8-11 minntronics (50-ping ribbon cable)
RLV112 Sigma

Couple of these look rather interesting.

Are you sure of that? Unless the floating point chip (and socket)
on an KDJ11-A or -B is identical to the one which is used on the
KDF11-A and -B (and I don't think they are identical, since the one
for the KDF is a dual chip carrier), it won't work.
The FPF11 board has a ribbon cable which ends in a connector which
fits the Floating point chip socket of a 11/23, 11/23+ and 11/24.

If you're determined to use a flatbed plotter to mill PCB's, you could
consider making a custom "quill" powered by a flexible-cable DREMEL tool.
You will need a really small (e.g. 0.020") carbide milling tool and LOTS of
them, since they break easily. I'd advise a very modest feed rate and, of
course, since you can't place traces at any less than 0.030" centers, and
that's pretty agressive, you will have to limit yourself to a VERY coarse
routing grid.
I'm told that you can expose and etch your own PCB quite a bit quicker than
you can mill one, and, aside from the chemicals and the associated disposal
problems, build better boards with chemicals than with a milling approach,
I'd suggest you look for a good, positive resist material you can apply with
the plotter in a refillable pen. There, your only problem will be in
adjusting the height of the pen and the speed of the plotter to allow for
the thickness of the PCB, and the thickness of the probably latex base
ink/resist.
