The bottom one has WY-700 PC HI RES MOTHER BOARD. Sounds like your beast.
If I should find one of these monitors would it work on a clone with just
this card ?

Yes if you plug the card in and plug the matching 700 monitor in it will come
up. The card emulates EGA & CGA. In its high res mode it is a nice sharp
1200X800 (approx.) monitor. It was supported by many early desktop publishing
software packages in it's high res mode. The original card & monitor set
predated VGA and was an 8 bit double card. I used one on an XT for several
years. SVGA finally killed them off.
I think I still have that XT. I know I have two of the monitors in my whse, If
I don't sell them beforehand they will be in my Auction in early November. I
am retireing from supporting a warehouse so most everthing is selling. This
will include lots of older computers, parts, terminals, printers and lots of
collectable stuff.

The situation is complicated by the large number of "Disk ][ clones"
that were produced in the early 80's. From personal experience and
advertisements, I'd say there were at least 30 different clones at the
time. Most of them used very different-looking, often half-height, 5.25"
drives, but many used the same drive mechanics as a real Disk ][ and
had case designs almost exactly like a real Disk ]['s. The only real
way to tell in this case whether you're dealing with a clone or not
is to look for an Apple sticker on the box and/or the Apple legend on
the drive's PC board. (While some of the clone makers also stole
Apple's PC board layout, I've never seen any that went so far as to
steal Apple's copyright and part number!)

The situation depends greatly on *which* version of the DEC boot
ROM's are in use. Some automatically search for an alternate CSR,
some allow you to specify it explicitly.
The situation is complicated by the fact that for most DEC OS's,
the alternate DU CSR is 160334, while for RT-11, SYSGEN will certainly
suggest something very different for the default:
> 230. What is the CSR (register) address for the second port (172144)?
While most DEC DU bootstraps "sniff" through 172144, not all do.
Luckily, we don't have to argue about the situation, as Zane told
us which bootstrap he is using:

So any discussion of DEC bootstrap revisions seems to be quite
irrelevant :-)
For many purposes, I much prefer the WQESD boot scheme. It
avoids all the confusion caused by the many, many different DEC DU
bootstraps!

Ok, TEAC FD55GFV (RX33) or TEAC FD55F (RX50). The cable must not have
twist and drive select is 1 for the first, I only use one on the system
as I have 3 RD52s. IF the drive speed select and density select jumpers
are set right it (using RQDX3) will sense what the media is and operate
correctly using the DU boot. None or all of this will be true for the
WQESD controller, I don't know it.

17772150 it the default first device and the default bootable. If there
is two the second will be at 17760334. For RQDXs the LUN jumper must
corospond to how many units.
I believe PDP-11 ROM BOOT expects to boot from the default first (*2150)
unless the DU.sys driver has been changed for the second address. RT-11
itself will boot/run on anything you have a driver for. Megan would
know for sure. I've never found it necessary to have two MSCP disk
controllers in a PDP-11 (I was using them in the vax instead!).

That's oblique. It's possible to make a bootable RX50(or RX33) that is
complete enough to be a system! To install from that is trivial as it's
really INITing the target drive (assuming its LL formated) and copying
everything to it then doing a copy/boot operation. Not much majik unless
the version of RT has been really tweeked.

Do you know if it's described in any magazine article? There is a 3 part
series about the first MMD in the May, June, July 1976 Radio Electronics. It
is an 8080 based system with 24 output bits and LED's, keypad, a solderless
breadboard, 256 bytes ram (2x 2111), and 256 bytes rom (1702A). The article
has the schematic and "monitor" listing and sample programs. I almost bought
one a few years ago, but the price was too much, USD $150. By the way, the
kit price back in 1976 was $350, assembled $500.

I'm sure there is an option for plain text, just not in quite the same

Plain text would be even better -- please don't post RTF, HTML, or encoded
stuff to the list (or anywhere by mail, for that matter, unless you *know*
the recipient wants it that way for some specific reason. Mail is an
plain-text medium).

No, there are plenty of us here who either cannot, or do not wish to, read
HTML in mail. Quite often we just silently ignore it.

But in all honesty, in areas other than old computers, one can find some

you'll see some amazing deals on donald duck stuff. 8^)

Subject: Chat Thursday
Folks-
Do you have an old Hermes in your basement? Do you collect
ribbon tins or just like to talk about it? Have an old pinwheel
calculator? When someone says they own a dusty old PET
computer, do you find your interest perk up?
This Thursday at 9 p.m.EDT (8 p.m. Central, 6 p.m. Pacific) we will
be hosting a live chat with Jay Respler, an antique collector from
Freehold, N.J. We hope that you will take this opportunity to visit
with other people on the Internet about antique office equipment
and even not-so-old office equipment now considered antique (the
Commodor 64, for example). To enter, go to the main chat page:
http://www.asaypub.com:8080/~chatrooms
and click the mouse on the "Yesterday's Office Chat." You will be
asked for some information, such as your e-mail address. Be
there. You will likely enjoy it. Please feel free to contact me if there
are any problems getting to the chat. You will need to have frames
"on" in order for the chat to work properly. We also ask that people
observe our chat policies of being courteous, waiting for an answer
before responding, etc. Thanks.
