Hmm... $0.50 or $1 per hour to prove you wrong? If it were my machine, I
might even take you up on that bet. Not a sure thing, though.

Good point. When I get home, I hope to be working on some stuff of this
nature (if I can't find a PT08, I'll have to build one; I have a PA60 that
nobody seems to know ever existed that would make a nice platform). I've
also thought about a non-rotating (reversible) mod to a DF32 since I'm
pretty sure my platters are screwed. At this point, all I can do is plan;
I don't have WW tools for the older backplanes.
Also, for a seperate project (peripherals for an -8/L), does anyone know
if it's still possible to find any of the bus strip for DEC backplanes.
They used to sell it on a roll - it had alternating large and small holes
so you could, for example, tie all the A1 pins successive slots together
(the version for the older, single-sided backplane was simpler, just a bunch
of sequential square holes in a line). I've thought about what it would
take to build a stamping machine to crank it out of something soft like
ribbon copper (then tin it), but my machining skills are much too primitive.
Any suggestions on finding/making bus strip?
