It's good to see that the MFM emulator worked on a 3640. I

For all I know, the disk controller may require special microcode to be
able to wri

The determined Real Programmer can write FORTRAN programs in any language. :)
But LISP /is/ pushing the limits of that …

Possibly as fast as it runs Forth or Perl. Two other write only languages.
I like Lisp, but it still is write only to my eye. I have to really
