IBM 5150 and Full-height 5.25 Floppy Drives

From: "dave04a(a)dunfield.com" <dave04a(a)dunfield.com> Hi Bob, I would be interested in this - I Am located in Ottawa, and am planning to be in Toronto later this month or early next month - where exactly are you located? And I have a pair of TM100-2 drives sitting on the shelf! The Horizon is a nice machine - used to have one years ago, and have not been able to find another... I have a NorthStar disk controller installed in my Altair, which runs NorthStar DOS as well as my own DMF system. There's a simulator for this machine on my "museum" page: http://www.dunfield.com/~ddunfield/museum/index.html

This will let you boot up NorthStar DOS on your PC! Also have most of the NorthStar manuals and a lot of other reference info. scanned and posted there, which may be of use to you.

A friend has given me another computer with those drives, but when I inspected it, I realized that it's a true-blue IBM 5150 PC in very good condition! The 5.25" drives' front panels are marked with the "IBM" logo, which makes them less-than-genuine for installation into a pre-IBM microcomputer. There may be parties that would protest stripping one "classic" to restore another: I'm hoping if there might be someone interested in both/either: - acquiring the 5150 as is (256K RAM [4 rows of 64K] on motherboard, plus 256K more on expansion card, no monitor); - supplying (Tandon TM100-2?) full-height DS 5.25" drives for the Horizon. The big hole in the Horizon's front panel really calls out for full-height drives. Any help/ideas/suggestions? I'm located in Southern Ontario, Canada and am contemplating attending VCF East.
