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, Kevin J.

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. -bob bloom

Correction, I meant port E0, not address E000. Kevin J. Belles - UUCP {ihnp4,cbosgd,sdcsvax,noscvax}crash!kevinb ~~~~~ ~~ ~~~~~~ - ARPA crash!kevinb@{ucsd,nosc}.ARPA

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. Kevin J.
