[net.micro.cpm] Info

I am seeking information and schematics on the Seattle Computer Products
SCP-16K Static RAM Board. I already know about how to address it, but would
like more info on the "bank" switches and the jumper at location V, also.

I am also looking for an explanation of what the jumpers on the Imsai SIO board
do. I would love to upgrade my speed on ser port a to 9600 baud +, and info on
the ser port b would be verrry handy indeed, for modem uses.

Further, I can't seem to get a program that will work on a PMMI MM-103. Any 
help on what the DIP switches on it do, and how to configure, for example,
MDM7, would be handy. I would love a chance to get a program that works on
a system using the SS NorthStar floppy drive system. I would be more than
willing to discuss buying/sending out a floppy to get the info copied onto.
Also, any suggestions on how to expand my CP/M to handle 52 to 56K. I seem
to be able to go to 52K, but I am not sure if the 56K interferes with the PMMI.
Expanding to 60K seems impossible, as the N* Disk controller starts at E000,
going through at least E900. Any ideas out there?

			Thanks in advance,

P.S. Any Imsais running out there - what kind of system are you running, using
what? We wanna know.... KjB

I don't know that much on the mm-103 but I do know the horizon.
The boot prom is addressed at e800 and takes 1k only.  There is
a prom set floating around that is addressed at fc00 - i'm sure a
request to the net for on would bring a response.  With phathomed
RAM, and the latest copy of northstar cp/m, a 60k system is possible.
(If you want more details - ask.)  with the fc00 prom one can get a
63k system.

Correction, I meant port E0, not address E000.

Thanks for the info, my documentation is more than a little confusing on
the DIP settings. Mine are arranged as in the following illus.:

		1 2 3 4 5 6 
		o o o O O O
		- - - - - -
		O O O o o o
		---OPEN----

where O is down, o is up.

I assume that this is the address E000. Am I right?
Also, are you aware of any schematics for the auxilary interface for this?
I'm interested in trying out a scheme for power-up on phone ring, answer.
This would be for a small remote system I have in mind, otherwise I would
just leave it running 24hrs/day, or so.
