No. IMSAI was a different company. The IMS rams, I had two of the 8kx8
were good stuff.

I know of a DecSystem 2065 in the Cambridge, MA. area that's looking
for a sympathetic home in the very near future, lest it meet an
unhappy fate. Any takers?

I have own a NorthStar Horizon very nice little computer abit heavy, mines
in the wooden box and has a pair of 5 1/4" floppy drives in the front and
yes it runs off an terminal.....
mine even has full docs and the origianl receipt of purchates from around
1976.....
many of the cards inside it arom from an Altair if my memory is correct...
A VDM -1? i think thats whats its called...anyway in the manual for this
video card it has the source code for the programmng code for a Altair and
IMSAl mechines....
only around 30,000 of these fine mechines where ever built so i would say
that they are very rare these days....

there used to be a good 'bow ftp site - do you remember what it was?
something along the lines of "ftp.ee.ualberta.com" or somthing; tried
every variation I could think of but didn't come up with anything... :)
seem to remember they had quite a bit of info on memory expansion
boards, connecting nonstandard floppies and other such stuff...
(one for regular posting to the list maybe? a list of good ftp sites /
web sites for various machines... or de we have a regular FAQ anyway?)

I think it'd run via the 80186 daughterboards in a BBC Master system
too... I'm sure I tried this years ago... (ok, "years" is kinda
relative! :)

It was sufficiently wierd enough that DOS barely ran and most apps didn't
like the climate. Even if windows ran, it was a 186... while faster than
a 8086 it wasn't faster than a 286. The 186 while a neat idea really did
well in the embedded control space where PC compatable hadn't poisoned
everthing.

yes ive seen pictures of Garry Kildor with a Lisa at his side...
They had a version under development but i almost sure they never released
it.....

The assumption is that the former owner of the boot disks has/had a
standard configuration. Of the systems my NS* controller has been
in the console could be:
VDM-1 and serial keyboard.
MITS SIO
NS* standard configuration (port base at 0)
CCS, 4sio
Computime CPU (on board usart)
Computime 4sio
All different addesses or requiring different initializtion or use a
totally different device. In my case the system was origially altair
with MDS controller so when the NS* crate was done I had to reconfigure
the disks for NS*. At the time you either got NS* personalized or
unpersonalized requiring the user to set it up it assumed you had front
pannel or rom monitor.

The right from the rear, left from the front.
The two devices are addressed at 02h and 04h, the console is nominally

It is possible to configure the software for any port however.

I recently lost a piece of my computer collection. I had a BRAND NEW never worn Seiko wrist terminal from the ealry 80's that downloaded phonelists, etc via the game port in an Apple II. I entrusted it to a jwewler for repair and he has lost it. I still have the origional box, software, etc. Anybody have an idea of the value of this piece?

Thanks!
