Hallo allemaal,

I just uploaded and it contains 
the source codes of the C64 V3 Kernal and JiffyDOS V6.01:
  - C64-Lee.a65 is the header of the V3 Kernal
  - C64-var.A65 contains the used variable
  - C64-bas.a65 is the BASIC ROM
  - C64-ker.a65 is the system ROM
  - C64JD.a65 is both the header and system ROM for JiffyDOS

Please have a look at them and tell me if there are things, like the 
layout for example, you do or don't like.

Next please have a look at the sources of JiffyDOS and look for '???'. 
These are parts of code where things happen I don't understand or like 
to know more about.

Another thing I like to know: you can use the @ character to send 
commands to the drive. The thing is: I cannot find the place where it is 
actually done. I know the place where the @ is handled: ChkIfJdCmd3 / 
F838. Then a check is done for certain commands that are executed using 
a table. If the command isn't found, JD continues at $F858. And then I 
loose track.

Any help is appreciated :)

Met vriendelijke groet, Ruud Baltissen
