     I am LT John Rossi III <[e-mail]>.  I have been reviewing
some of the archives from SIMTEL20 and I was somehow lead to believe
that AMSAA is a clearinghouse for info on CP/M systems.  I have tried
to access AMSAA by way of FTP and TELNET and have found that there is
no ANONYMOUS access.  Question #1 - Are you an interactive
clearinghouse ?.
     Independent of direct access to AMSAA, I would like to know if
you could point me in the direction of a place where I can obtain a
version of the MODEMx program in Northstar DS/DD (360K) format.  I am
currently conducting experimentsat U.S. Navy Subbase,NLON, NSMRL and I
would like to use my old standby N* controller based kluged computer
to handle some of the data.  My communications ports are by old
CompuPro Interfacer I boards so I need sufficient documentationalong
with the program so that I asn patch the appropriate linklages to my
user area.  I need the modem program for communication with a VAX-750
which will be handling most of the data.  Since N* is a hard sectored
format, I realize that I have two options, type in source code, or
find someone who can supply machine readable media.  I would prefer
the later and would be more than happy to pay for the service of
obtaining the software and documentation I need to get this project
moving.  Any advice would be appreciated.

Thank You,

John Rossi III

Friends,

Thank all of you who have sent me EMAIL concerning my current problem.  In
regards to the SIMTEL20 archives, through your helpful comments, I have
managed to access and extract many of the ASCII files.  I have snarffed
PIPMODEM and DOC as well as BASMODEM and DOC.  I have also read all the kind
suggestions made by everyone concerned who replied to my inquiry.  I wish
that I could report other successes, however with the information that I
now possess I think I know what questions I should really be asking in order
to get my current problem solved.
1) I still do not know the exact procedure for FTPing BINARY files
(esp. squeezed files) down to the VAX 780 here at NUSC.  Do i FTP the files
first then unsqueeze (if so how) or do I unsqueez first.  Also, assuming that
I have a MODEM program up and running (My PC-Clone runs MEX as well as PCTALK-3
and Crosstalk) how do I transfer BINARY files (I have been transferring ASCII
files using KERMIT (can it be used for non-ASCII transmission).
2) More related to my original question of communication between computers
in the same room (it was suggested that I implement a NULL-Modem), briefly,
I have a N* based S-100 computer (the only reason I mentioned this in the
first place is because of the 'oddball' 10 hard sector format used by the
system) which uses both CP/M and N* DOS.  The CPU for this system is a
CompuPro Z80, and it is a 64K system.  There are 2 I/O boards in the computer
(one) SSM 3P+S in which the Serial's UART is blown so it is a 3P, and (one)
CompuPro interfacer 1 (2-SIO).  The system was used (in addition to other
things ie. word processing etc) in the lab as a controler and hard storage
device for neurophysiological data which was sent in parallel from a 2 mode
data acquisition system I designed (8 bit-6502, 12 Bit 68000), this data
went through the 24 function parallel lines on the 3P+S.  The CompuPro
interfacer was used for the console and a serial printer.  I have long
since abandoned the printer so I have one vacant SERIAL channel which
can be configured in any way necessary DCE or DTE up to 19200B.  I would
like to use this port as a communications port, both for transmitting
binary and ASCII files to the PC-clone (which by the way, has a V20
8080 emulation program operating it so I can run CP/M applications) so that
I can analyze longer sequences of neurophysiological data (the N* program
I wrote was limited to 32K chunks), and also for generally communicating with
the PC-clone and the outside world for transfer of programs and what not.
The most important thing that must be accomplished (at least in the eyes of
the NAVY) is that I collect and analyze the data.  Therefore, establishing
a system for data transfer between the N* based system and the PC-Clone is
of the highest priority.
Question : Will I need to change the user area patches in the BIOS (CP/M),
which I wrote so it wouldnt be a problem, or do the MODEM programs access
the ports directly (also If the later is so, is the ample information in
how to set up the port configuration i.e port location #s, etc. included
in whatever documentation comes with the public domain progs)?
Question : In a null-modem arrangement, how should the ports be configured
(i.e., can they both be DCE ports or both be DTE ports with the pins re-
routed in the cable, or should one of the ports be DCE and thge other DTE)?
Question : I really don't know a lot about the innards of the PC-clone
except hrat it appears to be exactly like a PC and therefore the serial
adapter should conform to the DCA type setup.  On the other hand, I do
understand the CompuPro board and I can make it do whatever is necessary
provided I know what that is.  How should the ports be configured?
Question : How many pins in the RS-232 interface do I need to implement
a Null modem?
Question : Does public domain software shch as MODEM7xx operate with a
null modem the same as it does with a real modoe/modem link (I realize the
subtle difference in hoe the ports should be configured may need to be
different in the null modem case as opposed to a real modem case depending
on the nature of hte cable used.
Question : If i set up first for use with a null modem, will I in the future be
able to use the same software/system (minor modifications excepted) to
communicate with a mainfrane, say, through a real modem.
Question : Is this really worth the effort, or should I just put the S100
system in mothballs and hand enter my data collection routines into the
PC-Clone and use a TECMAR multiline parallel interface to collect the
data directly from the data acquisition system.
Question : If the answer to the last question is affirmative, Is there any
body out there who can transfer N* fiormat disks toa more popular type
of soft sector diskette format (IBM-PC, Osborne, Kaypro, Xerox, Morrow etc)
(for a service fee, of course) so that I can preserve my data, personal files,
and CP/M software for use with this son of a blue beast?

At any rate, thank you for taking the time to read this letter.  I would
greatly appreciate any ideas that you might be able to provide me with.

Sincerely,
LT John Rossi III
