Don,

Included in this .ZIP file are the two files created by TeleDisk. Note 
that I used TeleDisk 2.12 if that makes any difference.


FILENAME                DESCRIPTION
-----------------------------------------------------------------------
IF800BAS.TD0            This is the weird OS that I was referring to. It 
                        is quite similar to IBM's PC-DOS BASICA but is a 
                        complete operating system. BTW, it uses Z80 code 
                        internally and not 8086/8088. (I've done a 
                        partial disassembly which is how I know this)

IF800CPM.TD0            This is the CP/M 2.25 OS made by Lifeboat 
                        Associates back in '81. Lifeboat no longer 
                        handles CP/M in any guise so you're not likely 
                        to see any support from them. I got a less than 
                        helpful attitude when I went to them looking for 
                        BIOS source.


Anyway, if I can be of further help, just yell. I have IMP, MEX (and 
MEX+), Qterm, and ZMP all configured for the machine if your friend 
needs telecomm functions. The BMC uses an 8251a USART with an 8430 
baudrate generator.
