I'm sure glad I don't have to flip Switches to enter each byte as
the Altaire wanted the user to do.

OR

Press two seperate numerical Keys and the Enter key each time
to make a Hex Number as on the RCA 1802 ELF.

I did get to borrow a ELF after a friend got his TRS-80 Model I.

I read up on 6502 ML after I got the C=64 and the Monitor program
for it, but never caught on good enuf to be a ML Programmer.

My trys at understand 80xx ML was and is very hard.
To me 80xx ML 'looks like' RPN the way the addresses are set up to
look like xxxx:xxxx
And just recently I have seen the words BIG ENDIAN and SMALL ENDIAN
and I have no idea if 6502 Code is BE or SE, but it looked simpler
to me than 80xx Code does.

BASIC was easier for me as long as it had to do with Math or Strings,
Open, Close, Print, Print# and simple stuff like that.

I got the hang of Arrays but getting into the guts and changing the
code around at some locations with Peek and Poke is still beyond me
unless its changing Screen Color or other easy stuff.

I guess no Magazine has BASIC Programs in them anymore, but I
probably can still find some on the internet if I looked for it.

I remember seeing some ML Programs in BYTE Magazine a long time
ago and thinking I'd hate to type all of those pages and pages
of code in and thought that if I ever got a Scanner I could
scan the pages and use OCR to make a text file that I could
use to read the code into the computer for me.

I have tried Many Many different times to OCR something and all I
ever see is a BIG MESS!!!!!
The last time I used Irfanviews OCR plug in and failed.
I guess there are OCR programs better than the free ones I've tried
out, I wonder if anyone here has had good results using OCR?????
