Yes, I was aware of your work. Yours is up and running, where mine is a
ways away,
yet :-).
(I am making
excellent headway on a project which translate the 8/i
schematics,
including all the options, into Verilog for an FPGA, but I currently have
this signal
tied to an input pin for lack of any information about it.)
I realize it's not what you are doing, that is, I realize that what I did
isn't the same,
but I made an PDP-8/I clone in an FPGA, complete with the RF08 emulation
and
all the time sharing options. I consulted the schematics but didn't
follow them. The only reason I mention it is that if when you done
you want to boot
TSS/8, I have
images, complete with sources which might be helpful. I would guess that
at
some point you might want to try... (or maybe not, just a thought). I
also have
tools to put together an RF08 disk "image" from the sources.
Thanks, I'll keep that in mind when I get that far.
RF08 emulation with a IDE disk was fun in verilog :-)
I bet :-).
