Is file size correct ?

I'm trying to get some software onto my 8032 PET (not having much success but keep trying )

I've donwloaded some PRG files, they are roughly 8K each, I've converted them to WAV's using 'wavprg23', I'm then trying to save them from the PC onto Tape, so I can load them into the PET, they seem to convert OK, and come out as Wav files with a length of approx 1minute and 25 seconds.

I have a couple of questions.

1. Is this about right for this size of file ?
2. Am i converting these the right way ?
3. If I can get them to load, can I simply then save them onto disk for future use ?

I thought about trying to get a 1541 drive and X1541 cable, but from what I've found out it can't write disks compatible with my 8050 drive.

Also is there a way to convert .64 files to Wav or similar ? and I'm sure I've seen talk of a program to make an 80 column pet act like a 40 column, will this work with software then loaded from tape ?

What programs have you downloaded?  From where did you download them?

I got them from here

http://www.zimmers.net/anonftp/pub/cbm/pet/games/english/index.html

Random Selection, Cosmiads, Invaders, Super Glooper etc.

Most of these are for 40 Column pets, so not sure if they'll work anyways :ironisk:

Any pointers to other places for downloads is more than welcome

Here's another source for PET games: http://www.portcommodore.com/petfiles.php

I find tapes very unreliable but it sounds like what you are doing should work. Try loading and see.
Once you load from tape immediately do a DSAVE "filename" to save it to disk.

You are correct, the 8050 can't read or write 1541 disks and vice-versa. IEEE drives are a lot harder to get working with the PC, but not impossible. If you have a C64 you could get a 1541 and an IEEE cartridge so you can hook the 8050 to the C64 and transfer that way.
Instead of the 1541 you could also look for an MSD drive which has both IEC and IEEE interfaces so will work on both the C64 and PET (although I could never get mine to work with an XM1541 cable on the PC, plus they are getting more rare/expensive these days).

Another option is to build a CBMLINK interface that hooks the PET to your PC and lets you transfer that way, but you need to run a small client program on the PET to get it to communicate. You'd have to load that from tape initially then copy to disk.

As for the 8032 screen, you will need to get a copy of the "80240.PRG" which reprograms the 80-column CRT controller chip to work in 40 columns and patches the printing routines so most of those games will work. Failing that, most later 8032 motherboards could also be converted to 40 columns with a little hardware modification and by installing a new ROM, effectively converting the machine to a 4032 which is much better for playing PET games.

OK, I'm starting to get somewhere, with limited success.

I've managed to convert some prg files to Wav's, saved these to tape and then loaded them into my PET through the C2N tape unit.

Biggest problem I'm having is saving them to disk, as soon as they load I use dsave"filename",d1 seems to save ok and shows up on the disk directory ok, but when i load them back off the disk they won't work.

Is this because they are machine code ? when you do 'List' all I get is something like

10 sys(0699)

And that's it !

A program that starts like:
10 sys2066
Only uses basic to start a machine code program.
If you want to save a program like that to disk you use a command like:
save "program name",8,1
Maybe you should consider getting a 2031 drive which is compatible with a 1541 drive.
You can use a XE1541 transfer cable to connect the 1541 to your computer and transfer whatever you want to floppy.
Than put the floppy in the 2031 drive and you can load the program into your PET computer.
