Oooh,Oooh!!! <Jumping up & down 'cause it's the first, and no doubt the last, time that I've got a manual that Tony doesn't> I'VE got a TM100 Technical Manual !!!! (and a pile of TM100's, although not many, if any, to spare). In fact, I recently sent someone scans of the three main schematics, so if anybody needs 'em, no problemo, still got 'em (tif format) A popular source for stepper projects, and there are quite a few tech articles on the web by people who've built camera & telescope mounts, etc. with 'em & interfaced to printer ports. mike ----------Original Message------------- From: ard(a)p850ug1.demon.co.uk (Tony Duell) Subject: Re: Destructive charities (was: STAPLES STORES...) IBM Options and Adapters TechRef, TRS-80 Model 3 service manual. To name but 2 manuals I have that contain said schematics. I guess there would have been an official Tandon service manual, but I've not seen it (yet).
