RK03 was a Diablo. The big difference was the linear voice coil motor in the

I feel kinda stupid, given that the thing's original BIN was $1500; I
wasn't going to go that high on it but a friend of mine offered to chip in
at the last minute so I got outbid by $25 over the original BIN price.
No, someone with an unlimited amount of $$$ did a last minute snipe bid.

Not me. $1k would have been my limit, it's really kind of insane to run
something like that. As I put on my old memory hat I remember that the
platter would rust but at least the heads would not weld to the platter.
Also there were two timing tracks on it and

Always wanted on, to set up a TSS/8. I hope one of you guys gets it and can
put it to good use.
Jesus that went insane. I did not bid on it and would not have gone
above 1k anyway. Hope you got it.

There's a DF32 on Ebay. I've got a bid in on it, will see what happens.
In the unlikely event I win I'll have to build a system to adapt the
Negibus to the pdp8/L. However did the pdp8/L have 3 cycle data break?

I'm in the US, and have a couple people already volunteering their help.

OOPS on my last response... I should have said I found the original on
the CCTECH archive. Hope there was no confusion there!
FWIW, I went back to the CCTALK archives and could not find the original

Sorry Vince & Gary, it was my fault that the original cctalk posting was
deleted amongst the spam. It did get to cctech which is where Camiel saw it.
But before I could ask Gary to re-post, Camiel had replied so I figured
that everyone would get to see that.
