TRS80 M-3's & M-4's

Guys: I picked up a Tandy 15Mb disk drive unit at a thrift some months ago, with the idea that I was going to graft it to some old 8-bit hardware here. I was going to swap the controller with a different one, reformat the drive, and so on. Anyway, rather than do this, I felt it only just that I offer it here in case anyone is looking for one of these. It is in a White metal cabinet, and uses a WD-1000-TB1 controller. It has plugs on the back so you can chain on more drives. I suspect that this is used with upgraded model 3's and probly model 4's. The on/off switch uses a keylock (I 'aint got the key, though). I'll let it go to someone who can use it for $5 and shipping. I've never powered this thing up, so I dunno. . . . Jeff
