Now I have a question about transfering tape's files to disk.
Plain basic files are not the problem but those who has only one sys
<address> basic statement and a lot of machine language stuff appended
which is not visible by the list and save commands.
Is there anybody who know what I could do to copy my tape files to
disk?
I have no capabilities to transfer something between the PET and other
devices except the tape, disk and keyboard.
thanks

My best guess would be to write a small machine language program
(probably running in the screen area :-) to load the stuff from tape
and then save it to the drive.
IIRC Tape format for programs is different than for sequential files,
so you will have to call the LOAD routine and cannot read it
with GET#

Yes I agree totally.
I saw such small program (see listing below)on the net but it was
written for C64. I have not enough knowledge to write such program. I
know 6502 assembler, that is not the problem. I have no knowledge
about the information I could find somewhere on the RAM after loading
from tape and what I have to do for save it back to disk.
By the way. I have an c2n232 adaptor to read files from and save them
on my PC by using c2nload. But the problem still exist, I can not bring
it from existing tapes to 8050 disk drive.

Don't they just SAVE properly? I would have to check how the PET handles
that but on a 64 short to medium long prgs with one basic "sys" line do
save without problems in most cases. The longer one start to be more
problematic as they are stored in the RAM areas unavailable for BASIC
(and therefore SAVE command). Not sure if that would work on a PET but
have you tried LOAD followed by SAVE to the disk?
