I'll tackle the physical layer first: any RS-232 interface for the C64/128
will do. A null modem just "exchanges" certain lines and, since C64 terminal
programs don't do hardware handshaking the following schematic will do:
Pin Pin
--- ---
1 ------------- 1
2 ------v------ 2
3 ------^------ 3
7 ------------- 7
8 ------------- 20
20 ------------- 8
Note that pin 2 on one connector is wired to pin 3 on the other, etc.; the
pin 20 - pin 8 bridge fakes carrier detect (may not be necessary); pins 1 & 7
are ground, they may be commoned so that only one wire is needed in stead of
two.
If you're using an Omnitronix Deluxe (or similar interface), you can get
away with changing the switches to "printer" from "modem" and you don't need
to cross the wires at 2 & 3 (a "gender changer" may be necessary, though, to
get the interface to plug into tha Ami... then again, it may not, depending on
which model you have... I think...)
OK, now software: I suppose you could write custom software if you want to
move masses of programs accross, but it might be quicker & easier to do it
this way:
OPEN1,8,2,"asciiname,S,W":CMD1:LIST
PRINT#1:CLOSE1
Now load up your favorite terminal and send [asciiname] to the Ami (this
will convert from PETSCII to ASCII). If the program list is too long (which
may be the case), simply use LIST xxxx-yyyy to list a range and merge them on
the Ami.
Please keep in mind that anything but trivial programs will have to be
modified to run under AmigaBASIC; programs that use PEEK, POKE, SYS, or USR
may be particularly difficult.
