( This may be a repeat, but I didn't see it on the net )

I have several of these tape machines but very little 
time to work on them. I would like to give one away 
in exchange for a working interface.

I propose the deal to be :
	You send me $40
	I send you the stuff listed below
	You send me working software + cable diagrams
	I send you $40

Ongoing discussions as to functionality, problem solving 
would be expected. etc. 

Anyone interested?
Anybody want just a drive?
