I have a slightly off topic question for
I have never made a PC board or trace routed or
optimized a board.
Could you explain the process?
How do you start with chip placement? What software
do you use? Is this a professional version or is it something a hobbyist could
get freely. What kind of computer is the board designed on, is it
How long does optimization take to complete? It
seems like it takes weeks or months to complete. Is this run on a modern
computer? Is optimization different that trace routing or is it just the final
step of the process?
I know that's a lot of questions but you did ask
Thanks for all your work.

Subject: [N8VEM-S100:1455] S-100 board
Well I was hoping to get the S-100 68K and S-100 80286 CPU
board PCBs ordered next but they are not cooperating. The S-100 68K CPU
board is nearly complete and should be done soon. It has taken much
longer than I expected though. I would like it to complete trace route
optimization before ordering PCBs.
In the meantime, I am thinking we could make another
round of S-100 board reorders. What I am thinking is the S-100 IDE V2
PCBs are always popular and so are the S-100 buffered prototyping board
PCBs. I would like to do another round of those and hopefully while they
are settling the S-100 68K CPU and the S-100 80286 CPU boards will complete or
at least get ?close enough?
Another idea is the S-100 bus terminator board.
Basically there are 10 builders willing to get these boards ?as is? which is
the full sized PCB with some prototyping area. Nothing fancy but useful
for terminating a legacy S-100 backplane. However these have
*NOT* been prototyped so there is some additional risk. I think
it is minor though since the S-100 backplane has this exact circuit and it
Ideas? Thoughts? Comments?
Questions? All welcome! Please lets discuss what the next steps
should be. Thanks and have a nice day!
