    I really should have been more specific in the first
posting. Here is a list of the things I know or have tried:

1]  The MAC isn't true RS232 either. I checked with a local
APPLE service centre & found out that the MAC will accept
TTL. Today I'm going to clutch at a couple of straws and
try a 64 ==> RS232 converter I built a while ago, after I
buy some fresh 9V batteries for it (The converter was a
project out of an Electronic Today International magazine
(Aust ed) project# ETI-1601; it uses a 1488 & 1489).

2]  I've tried tweeking the bit-rate timers for the RS232
routines in the 64, No success.

3]  It is possible that the user port on my 64 is damaged
(PB0 could be playing up) - I'll check this by using my
VIC20.

4]  The ASC codes: Speedscript allows you to save your
document as a ASC file. When I was testing the null-modem
cable, I just used a quick&dirty routine that came out
of the VIC20 reference manual (modified to 8N1 of course).

Thanks to all,
        Sincerly C.Baird.

P.S:    If any old 64 owners out their have to use
(involitary) a Macintosh as a part of a job/Uni course/
whatever, I've recently recreated the 64 character set
as a font resource on the Mac. The Upper and lower case
characters are avaliable (I didn't include the C= shift
characters because I couldn't be bothered working out the
corresponding character codes). I could post it
here if you want.
