Looking for Petspeed or another PET compiler

[Tristan Miller]

Dear all,

Can anyone help me locate a copy of the original Petspeed compiler for
the Commodore PET (not its later conversion for the Commodore 64), or
any other BASIC compiler for the PET?

Regards,
Tristan

Thanks. Any idea if there's a manual specific to the PET version? I
tried both petspeed-80col.d64 and petspeed.d80 -- the compiler launches
and prompts me for a filename, but after that I always get the following
error message:

disc error for programname: 74,drive not ready,00,00

Possibly the compiler works only with certain PET models, or certain
disk drive models, or is expecting a blank disk in the second drive of a
dual disk drive... I've blindly tried a few different combinations but
so far nothing has worked.

Oh, never mind -- I found the manual at
<http://www.6502.org/users/sjgray/mikes.html>. Turns out you need an
8050 or 4040 dual disk drive with the compiler in drive 0 and the
program to be compiled in drive 1.

Unfortunately, I still can't get it to work -- no matter what PET and
dual disk drive model I try, I get a CPU jam during the first pass of
the compilation. Looks like people have reported something similar
happening with the C64 version of Petspeed:

According to the manual, the compiler uses a hardware dongle (plugged
into the first cassette port) for copy protection. It could be that
this is the source of my problem. (I'm running the compiler in the VICE
emulator, which obviously doesn't have access to the dongle.)
