This is why the IBM Basic would not run on clones. You certainly could put a correct pin out EPROM in one of the sockets and read it / write its contents to a disk. Nanoman.

It is possible that there were excess tracks when a 3 1/2 inch disk was added to a system with 8" drives, especially at Altos. there may not be any relevent data on those tracks, or if there is, you may be out of luck unless you figure out how to get a system going with 3 1/2 inch drives and gen an 8" disk off the Altos system. Some systems never used the 3 1/2 inch drives as a main drive, but rather as a convenience. the system never knew there was anything other than 8" drives attached. I recently saw that with old Computer Automation systems, for example. jim

It would be easy enough for anyone with this archive to locate the above referenced files and clean them out. I don't have the cleaned Maslin archive on my site but I could post. I think I took it down after a while. Don't remember. My site is not geared to be an all inclusive archive for things like that. Bill Degnan twitter: billdeg vintagecomputer.net

Bondwell 12 update + new scans...

by geneb＠deltasoft.com

I stopped off to pick up the Bondwell and discovered two things - it DOES have a couple of disks tucked into the little slot underneath the drives, and the proprietor may want as much as $75 for the machine. The employee didn't know for sure and the machine wasn't priced. The person thought the price was "something crazy". I told him if it _was_ $75, it wasn't crazy, it was insane. I'm hoping I don't have a local version of wiredforservice or computerhistorymuseum on my hands. *sigh* I left my contact information - if the guy wants more than $20, he'll enjoy keeping the machine. On to the goodies... I've added a Z-System software catalog and issues 1, 3, 4, and 5 of the Z-Letter as well as an issue of ComputerLand magazine. Hit http://www.retroarchive.org to check 'em out. tnx. g. -- Proud owner of F-15C 80-0007 http://www.f15sim.com - The only one of its kind. http://www.diy-cockpits.org/coll - Go Collimated or Go Home.

Political correctness is a doctrine, fostered by a delusional, illogical minority, and rabidly promoted by an unscrupulous mainstream media, which holds forth the proposition that it is entirely possible to pick up a turd by the clean end.

It'd be okay for DOS/*nix stuff, but > tough luck on those Osborne I floppies. I have to apologize to you all, I wasn't specific enough. The discussion has been a great read though. :) I've got a PC with a limited space case. They didn't even include room for a 3-1/2" floppy drive in it. I'd like to be able to read DOS and non-native format floppy disks with this machine as part of doing an update to the retroarchive.org site. Instead of building a second machine, I'd like to be able to find a way to interface a Teac FD-55GFR via USB. Barring that, I'd like to know where I can find a desktop ATX form factor case that's got bays deep enough for a standard sized floppy drive. Thanks all! g.
