First:
I have a bunch of Model II software! Problem is I am not sure how much is
any good.... Anyone know how to read the data off of the disc and
preserve the programs???? Anyone have any clue as to how to make a 3.5"
floppy replace an 8"???

I have the TECHNICAL MANUALs for the Model II. As soon as I can dig them
out, I want to scan them and put them on the net in PDF format.... Anyone
interested???


Now on to my replies:

No seriously, the Model II can page (I think it was the upper) 32K of
memory IF you had extra memory cards. This feature is built in.

I wanna build my own ARCnet cards which is why I asked "does anyone have
the spec.s (electrical and data format) for ARCnet?"

I have called Datapoint and they are useless. I have contacted the ARCnet
Trade Association and they want lotsa $$$$ for copies of the RFC. Why
would I spend $100.00 for an RFC when I am just a hobbyist?
