View Full Version : Pet 2001 + 2040 + d9060?

I have the chance to get a PET 2001 (with the typewriter keyboard like this (http://classof1985.org/classblog/wp-content/uploads/2008/06/commodore_pet_2001-321.jpg), not the chicklet one) as well as a Commodore 2040 dual floppy drive (http://www.classiccmp.org/dunfield/pet/h/d2040f.jpg) and a Commodore 9060 hard disk drive (http://www.commodore.ca/gallery/hardware/9060_hard_drive.JPG). I have never really messed with Commodore stuff before (other than a VIC-20 and a Commodore 64) so I have no idea if either external peripherial will work and if they do work, can they both be connected at the same time?

Yes they will all work together. I'd kill for the 9060 drive myself. They are tough to find. ;)

I got a possible lead on one however from what I heard the hard driv is either not installed or dead. :(
I'm hoping I can replace it with say an ST-225 which I have a bunch of should I need to be looking for a new disk.
Also, how would one go both accessing the drive and formatting it? is that all in ROM?

I think there has been a lot of discussion in cbm-hackers about doing just that.


If you check the recent archives you might find some info about it.

If you have a D9060, just replace the Tandon 602s with a ST-225 and it'll work.

Here is a thread from my web site that tells you have to replace the hard drive with an ST-225, for the D9090. For the D9060 skip steps 1 and 2.

I suggest that you test the St225 in an IBM PC first to see if it cleanly formats. It will not hurt to do this before putting into the CBM drive, and it will remove the "does this drive work?" variable.

If you are unlucky, the logic boards inside the 9060 are dead as well. Once you connect it, you could try to read the error/status channel to find out if you get any action at all. I picked up four of those a few years ago and with a lot of patience managed to get two (I think?) somewhat functional, albeit not for long.

As for connecting both drives to the chain, it should work as long as they have different device numbers. I'm not entirely sure how that can be altered by hardware but if powered on one at a time you can software wise change the device number temporarily.

Alas, the hardware eluded me.
It was picked up before I arrived so no commodore gear for me this christmas. :(

Too bad. On the positive side, that stuff tends to occupy a fair deal of space so after a while you might've begun considering where you can put it away to storage. It seems not even the regulars on certain Commodore related mailing lists have that kind of gear installed and ready for instant action. I brought a PET 8032-SK and 8250LP floppy drive from the basement last Tuesday for some hobby action. I'll see if I keep it available over Christmas and New Year, but most probably it will go back to storage some time in the beginning of 2010. Not because it is dull, but because it occupies more space than I have spare time to regularly play with it.
