Commodore CBM 8032 32B?

So I got some pics:

And inside:

You can see the front clips into two openings, and a few of the mounting points for drives.
 
So were there floppy drive versions that aren't Rohde & Schwarz? (dumb question but it seems to be the only pictures found). Wonder if one could find a drive and controller to fit the machine,

I've certainly never seen any other 8032s with internal drive(s)

Drives are no problem; wonder if I could talk Dave Dunfield into letting us try to clone his 8" drive interface... ;-)

Commodore never released anything for the square-cased PETs. There is one other that I am aware of called the Malvern "particle sizer". This is an 8296 with an SFD-1001 drive in a custom case.

There is definately enough room in the 8032 case for a drive like the 2031LP or SFD-1001, or perhaps even an MSD-SD2, so if one was ambitious one could install a drive themselves. I'm not sure how it would look. You'd have to build a new bezel for it, similar to the 8296D machine.

Aw... nobody's impressed by my dual-1.44MB-drive 8032? ;-)

Actually, this thread has sort of revived my interest in this useless (like most) project, interfacing to PC-compatible floppies via the IEEE bus; wonder just how hard it would be. There are interfaces to a PC and Flash RAM so it oughta be doable...

I think I missed the picture the first time. Anyway, it's really quite easy... Just build an IEEE2IEC interface (http://ieee2iec.t-winkler.net/) , connect a 1581 drive that has been modified with an Amiga HD floppy mech and patched roms (ala Commodore 1590 protype drive- http://www.floodgap.com/retrobits/ckb/secret/periph.html ). Piece of cake ;-)

Or, hack the 1581 to use an IEEE interface, something like the reverse of this:
http://vintagemashups.net/2010/12/commodore-1541-ieee-488-conversion/

Or, hack an MSD SD-2 to use 3.5" drives (it does use a mostly standard floppy drive interface connector)

As you say, piece of cake! ;-)
 
lol Mike, I totally missed that it was 3.5" as well. Is that really your handy work? ;-) Looks more like a case mod system. As far as interfacing I honestly would think there's probably enough room in the Pet to disect an external drive, connect the cable and mount the guts/controller internally then put the drive in that slot. I would imagine it just might not be that pretty or faceplate issues may keep it from being a (good) working drive as it ejects the disk to just inside of the case or something heh. But that's my non electrical mindset.

Well, of course they're not connected; that was mostly just for fun, but it does show that the narrow 1.25" high drives used by Compaq fit perfectly in the 8032-32B cutouts. I'll see if I can find at least one of the narrow 5.25" drives; they should also fit perfectly, but are harder to find.

@Steve: Did Commodore use any 1.25" high drives like those Compaq drives in any of their later models, or are they all standard half-height?

And where's Hexsane in this discussion? He did that IEC>IEEE488 conversion and writeup and also did the FAT40>8032 conversion as well...

No, just standard half height.

I think the challenge is on... who's gonna be the first to make a working square-case PET with internal drive in the new millenium?

As far as interfacing to IEC devices this is a version in action using a SD card, you can see the light when I access it for the directory. It is daisy chained as device 10 right off the 8250. Also can someone give me a link to basic 4 disk commands or tell me the command to copy files from device 10 to the 8250 device 8 d0 d1?

It is the Copy command but I do not think it works between units. You may have to store files temporally in the PET.

I have a pdf copy of the User's Reference Manual for Version 4 in my hard drive but can not remember where on the web I got it. I will upload it if you can't find a version.

Haven't seen that IEEE488<>IEC interface before - nice; where'd that come from?

Isn't that an XS1541, an Austrian design?

See also the ZoomFloppy, in case you missed it:

The zoom floppy still doesn;t have 488 support just port provisions for it. The same person (diddl) that wrote the code for the XS-1541 has done some code work on the zoom floopy, but the problem is with star commander not supporting the transfers yet.

My device is a prototype that nils had built.
