Right... but default secondary device for a DU handler is 17772144.
(The reason for this is because back when the driver was developed,
someone decided that since the vector was programmable, and the default
was at 154, and nothing was at 150, that subsequent vectors would
decrease by 4. This was then extended to the CSR... It wasn't
until later that we found that the default secondary CSR was to be
at 17760334. It never got changed. I think it is still that way
for the to-be-released V5.7)

So long as the address/vector match what is set in the device handler,
it should boot. (I have a system at home with three, and at times
four, MSCP adapters for various disk types -- MSCP, SCSI, ESDI, DSSI)

Either ways it's not an issue ans the numbering system is more than 4
digits. For example my 8550-031 (ps/2m50z) being differnt from the
8550-021 (PS/2m50). How else would they differentiate models in a
family of products.

I can't check for a model number, because I no longer have the drive. I do
remember that it was all black, had a Disk II - type face (with the
non-wheel head motor), and that it said "Apple" and had a red apple (not
multicolored) on the front.

Does anyone know about this thing? It's a black machine, looks like
a PC clone. I gather this is an Apple ][-compatible?

I just gave up on trying to read it.

I read that you have some that may use old computers. I have 3 of them 1 128
commador and two 64 with about 200 programs and game and a lot of blank disks.
hat to just throw out on garbage if you know some one that could use them,
trouble is the would have to pick them up at 101 old lanes mill rd. brick nj
08724 7324581582 as I'm 81 and do not drive too much
In a message dated 98-10-13 20:40:07 EDT, you write:
<< he few ISA cards was a 16-bit double card with a 9 pin external plug
labelled
Wyse monitor. There's 2 badly mounted Wyse E-Proms. Printed on the bottom of
the top board was WY-700 Controller Daughterboard. Wyse Technology (c) 1986.
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 ?
T >>
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.
