I have a 5.25 inch diskette that was created on a PET CBM 8022 using the program WORDPRO 4. I desperately need to transfer the data from those files and put them onto a IBM PC-DOS readable format so I can import them into WORDPERFECT or something. Is there some sort of device driver available that will allow IBM PC-DOS to read diskettes created by a PET CBM 8022? Does the PET CBM 8022 have an RS_232 compatible serial port? (I could connect to the IBM PC in host mode and transfer the files.) Is there a program on the PET that will write files in IBM PC-DOS format? Are there any other ways that I could at least transfer the file from PET format diskette to a PC-DOS formatted diskette? If so, I could use Norton Utilities to extract the data from the WORDPRO file. Anyone with any ideas, please contact Nate Charles ( garlands@athena.mit.edu) or post to the net, if appropriate. I'd appreciate any and all leads, no matter how small. Nate Charles garlands@athena.mit.edu Thank you.

If you can find somebody with a 64/128 and a copy of Big Blue Reader, it might be possible to have them do the conversion - I have never tried it. Otherwise, you may be "stuck"... (and the BBR cannot work if the files are in 8050/8250/SFD format).

Nate charles asks how to convert his 8022 diskettes to PC format. First, I think he means 8032. This is the name of the machine. The disks might have been made from either a 4040 or 8050 type drive. If they are 4040 format, then a 64 or 128 style computer can read them. If they are 8050, I don't know what to do. (If they are 8250, then they are double-sided 8050 disks.) So, I don't know if there exists utilities in the 64 world for such conversions, but if you have access to an Amiga with a 5 1/4" drive, you can read the files into it with a program called disk-2-disk, and then write them out as PC files with another program, Dos-2-Dos, for example. I don't know what format disk-2-disk reads, but my guess is just 4040 style. I have an SP-9000 with a 4040 drive, and an Amiga with a 5 1/4 drive and Dos-2-Dos. I do not, however, have disk-2-disk. If we can work around this somehow (ideas?), I'd be glad to make the conversions for you if you send me the disks. And no, the 8032 does not have a standard RS-232, though there are cables and software that can connect to the parallel port to make it mimic an RS-232 for communications. (This is what I use.) Good luck, let me know if I can be of help. Scot sjk@astro.as.utexas.edu sjk@emx.utexas.edu

Please don't take this too personally, as it will no doubt come accross as very harsh and I don't mean to bite your head off: In article <1990Feb26.175510.12858@athena.mit.edu> garlands@athena.mit.edu (Nathanial G Charles) writes: >I have a 5.25 inch diskette that was created on a PET CBM 8022 using the No, it wasn't. The 8022 was a printer, and these tend to have VERY flaky read heads (with a few notable exceptions), so they weren't used very often for read/write storage. >I desperately need to transfer the data from those >files and put them onto a IBM PC-DOS readable format so I can import >them into WORDPERFECT or something. That's not too difficult, if you can tell me the model of disk drive used to format it. Your choices are 2040 (unlikely), 3040 (even more unlikely, unless you're in Europe), 4040, 8050, 8250, or SFD. I currently have a 4040 sitting here and could fairly easily get access to any other format. Therefore I could probably copy the files from the Commodore format disk to an IBM format (preferrably 360K 5 1/4"), as long as there aren't too many - the procedure will be manual, slow, and tedious. >Is there some sort of device driver available that will allow IBM PC-DOS >to read diskettes created by a PET CBM 8022? The Commodore drives used, in their native mode, Group Code Record ("GCR"). This is a modulation scheme similar in concept to RLL and, sadly, beyond the capability of any PC floppy controllers I know of. >Does the PET CBM 8022 have an RS_232 compatible serial port? >(I could connect to the IBM PC in host mode and transfer the files.) There are existing routines to do serial I/O on the pins at the back of the machine, but they are slow and clumsy. Depending on the format of the disk, I'd be doing the transfers at 4800 or 9600 bps using a C64 or a Commodore 128. This single application doesn't merit porting my fast serial drivers (and someone's terminal) to the PET. >Is there a program on the PET that will write files in IBM PC-DOS format? The drives that plug into the PET have their DOS in ROM, and use CGR so they are not capable of writing MFM formats like the PC's. >Are there any other ways that I could at least transfer the file from >PET format diskette to a PC-DOS formatted diskette?

I'd appreciate any and all leads, no >matter how small. Copy the files onto a new disk and send it to me. I'll transfer them over and filter the WordPro 4 character set to ASCII so you can read it into Word Perfect. Note that the result will NOT be a document file, and it may take a bit of work to make WP format it the way you'd like... that's strictly up to you. If the files don't fit onto one disk, then we should talk about a nominal fee for time spent, or someone with a bit more time on their hands could undertake the same task. Sound fair?

That's intriguing, but still depends on a fair amount of translation/etc. How much material are we talking about, anyways? If it was megabytes, I'd see more reason to go to the trouble than if it was just kilobytes. Another thought is the parallel user port, if you could hack the IBM to receive a parallel 8 bit signal and you had the patience, you could make an interface like that. ... Joe

Yes, if you can get an IEEE-488 card for the IBM, and know how to program the port on the PET, you should be able to transfer information. I recommend, however, that you write the program in machine language for speed considerations. Another possiblity is to use the "parallel port" on the PET (i.e. that "other" connector on the back) which can be accessed from BASIC or ml. I used this to connect my PET to a Centronics printer (although it was a custom cable...) I DO remember reading a few years (~ 5) ago about an parallel-to-serial converter that attached to the IEE-488 port that gave RS-232 I/O through the 488 interface. Sorry I can't give a reference. --David Plass

1) Take one commodore, one 1571, one serial interface, one PC type computer.
2) Connect commodore to PC with serial interface.
3) Upload file with Kermit or DesTerm128, save to PC type floppy disk.
I know this is oversimplified, but should work. I've done it several times
here. My 1571 can read 4040 disks, what exactly is an 8080? (2 4040's?)?
Maybe try copying the file to 1571 format, then using Big_Blue_Reader.
The idea is to use a newer yet compatible commodore computer to get the file
to another machine (DOS).
