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???
Ooo yes , please !! I almost missed this with all the s/n ratio going on.
There's almost no documentation available out there on the model II much
less programs. By the sounds of it you don't have one. Yes it is possible to
transfer it to 5 1/4 according to others I have been in contact with. TMK
Tim Mann is working on an emulator. One of the things on my plate is to
transfer my programs to a newer media, to conserve them. I'll let you know
how this progresses. There was also a thread on this very thing recently on
comp.sys.tandy.

Note: on the Model II (TRS-80) there was an option to
use page the memory
so you could get more than 64K in the thing.... If I remember, it used a
Z-80 I/O address as the pager.
To the best of my recollection, the only serious memory paging that Now on to my replies:
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?

Tandy ever did with the Model II series was the
16k (each) in the
Arcnet and hard disk boards and the 32k in the graphics board. Some
other vendors went further with it, but as a Tandy customer support
rep, I never saw them in person. The Model 4 was a different story.
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.
Damnit!
I want a 64bit Model II !!!!!!!! (Running and 500Gcyc of-course).
With 8" Laser-Optical drives... and OH OH!!! I want a Thomas-Conrad
100Mbps Fiber ARCnet to connect it to my Linux machines!!!!
Won't do you any good unless you also build (and program) the
custom Arcnet cards, since Model II Arcnet spoke only to Model II
Arcnet, even though the hardware and connection layers were
compatible with Datapoint and (later on) PC Arcnet systems.
I installed and supported Model II Arcnet, later on I installed
Vianet based on Arcnet hardware for PCs. The wires and hubs and
signals were the same, but the machines talked different languages.
