I suspect the main skill needed is in writing checks ;-).  You can see a
picture of one on the Living Computer site, if that helps.  What would
you do with one if you had it?

I'd personally find it difficult to keep a box like that around the
house unless I was getting real use from it.  I've played around with
software emulators but that's different, it's just some bits on a hard
drive.

Well of course I have no real, objectives other than my general curiosity.  I just wondered if building something like this (by a rank amateur) was at all possible in FPGA.  I've played around with the SIMH  PDP-10 emulator on on my Pi but I would like to do "more"

Thanks!  Andy

Writing verilog is different than writing C, but if you have a schematic diagram
of the processor, it isn't so hard to convert that into verilog.  Otherwise, you
need to get used to thinking like logic, where everything happens all the time.

Microprogrammed processors are simpler, but then you need to find, 
or write, the microcode.  

It would be usual to start with a simpler project, so maybe a little above
rank amateur, but less than professional.  At some point, it just takes time.

It's entirely possible.  There's an FPGA implementation of the KS10
processor that runs the original microcode.  (It's not finished yet.)
There's another project to create a close replica of the PDP-6 and KA10
in Verilog.  David Conroy's PDP-10/X design was finally released to the
public not long ago.

A few attempts have been made to make a KL10 microcode compatible thing,
but nothing that advanced to a usable state so far.

I have microcode source and assembler ready to go, so don't be shy.

Or for that matter, the XKL version of TOPS-20?

I'm curious -- was this a fortuitous find of an NOS or used system, or
is it somehow possible to obtain these machines new?

So I did sign up for a free account on kankan.  I know my user-id but I 
forgot my password.  What steps can I take to reset my password???

Thanks in advance!!!
