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.
RF08 emulation with a IDE disk was fun in verilog :-)
