I just modified my program to get rid of the polling.  It did not really 
speed up the display of characters.  ; )

I can now see the full records with some duplicated digits here and there.

Its interesting that the program below free running can only process 
characters at 300bps

1 POKE 61441, PEEK(61457)
2 GOTO 1

At a 500Khz clock thats over 1000 clock cycles per loop.  SO THIS IS HOW 
Micro-Soft got started with slow software???  ; )

So any suggestions on getting started QUICKLY with 6800 assembler?  Maybe 
one that outputs in Motorola punch tape format???

I want to archive Altair 680 KCACR basic before anything else happens to 
this tape.  I had about 5-6 failed loads this weekend and I don't want to 
risk loosing this KCACR basic!  : (
