Thanks! That will be very helpful!
Hi all --
In addition to the 11/45 project I'm also working on restoring an
RF08/RS08
fixed head disk/controller (in the vain hopes of one day running TSS/8 on
my PDP-8/I). I have the power supply repaired and running and I'm getting
ready to power the logic up (the disc itself will be a project all its
own,
once it arrives).
I'd like to double-check that all the flip chips are in their right
places;
I have no cause to think they've been shuffled around but I want to be
sure. The engineering docs have detailed schematics but no placement
chart
for the modules themselves. Given enough time with the schematics I could
derive this chart but I'm saving that as a last resort. So, two
possibilities here:
1) Does anyone know of a document I've overlooked that includes module
placement?
2) Can someone with an RF08 and/or RS08 take a few detailed pictures of
the
logic (from the handle side, of course) so I can compare? (Note: the
available RF08/RS08 pictures on the 'net are of the unit currently in my
possession, so are not useful in this regard!)
I have a RF08 / RS08 combo. It was connected to a PDP-8/L, but the cabinet
with the DW08 was missing.
I can take a bunch of pictures next weekend.
I have a vague idea that I have a bunch of docs with the unit. Double
ledger size or around A2. I will have a look.
Would be very interesting to read your story when
repairing it!
I'm going to try to write about it, we'll see how good I am about keeping
up. Still slowly writing things up about the 11/70 from earlier this year
and I'm behind on just about everything. I imagine getting an actual
physical disk working is going to be an unlikely prospect, my plan is to
develop some hardware to emulate one or more RS08 drives, eventually. But
I want to try the real thing first :).
