Any one to avoid? It'll end up in an Axil SS2 clone routing a broadband
connection into the FDDI backbone, unless someone can convince me that it's
a horrible idea.
Thanks!

hmm, that's sounds about the right size. I remember the lecturer standing
behind the platter and it came up to around waist height, which is where I got
the 1m estimate from.
thanks to all for the thoughts!

I picked up one of these today and it had multiple problems but I finally got it to boot but so far I can't get a display on the built in screen. I'm not sure but I'm wondering if the switch settings on it are correct. Does anyone have the switch settings for one of these?

Um, I'm thinking Sony diskette drive part numbers start(ed?) with MFD.
Yep, it looks to me like you got yourself a drive tester.
That wouldn't get me so excited as to forget to hit return once in
a while, but I guess it means you have a new way to play with
the stiffy drives in all that HP gear. Congratulations!

Hey guys!
You may want to check out the Computer News 80 website at
www.cnpublishing.com for information on software for the TRS80, as well
as TRS80 Model 4s for sale etc.

You are very lucky to get a Sony tester. IIRC the early Sony drives were very
nonstandard and there were several different kinds. I am sure the 70 track
goes back to the very earliest Sony floppies there are others on the list
that can address this better than I.
I can't remember who made the Hard drive tester that I have. I got several
>from Intel when they were getting rid of the 310 stuff. It covered most of
the early MFM hard drives and was built in a small blue box about 12" square.
A standalone process selected from a menu of drives, plug in the drive, after
a while a report was printed out. The name started with an A and was three
letters. IIRC. It is close to the surface in the storage locker so I will
note when I get there.
You got a nice find. Hang on to it.

Just the thing needed to check out those sony drives in the old HP equipment.
Congratulations, Joe, you have a floppy drive tester for early Sony 3 1/2
inch floppys.
I have a similar hard drive tester.

I've put together some pictures of parts of my collections of various
things that I figured I'd brag about^H^H^H^H^H^H^H^H^H^H share with
everyone on this list :-)
There are pictures of various DEC PDP's, tons of pictures of boards,
some antique test equipment, and some antique electronic calculators.
My question is, does anyone have schematics for any of the non-DEC
equipment? Specifically, GR1683, HP3440/3445, HP9100, and Tektronix 909?
If so, please let me know! I'd be happy to host PDFs or GIFs or
whatever form they might take...
