I refuse to use a socket that is more than $10. I like small hammers
- less problems when you hit your thumb. I am also conservative - why
use
something bigger if you don't need it. The other design goal was to have
CPU designed about the same size and speed of 8086/6809 era chips.
Since I have no way of having a chip of 80's technology made I have to
limit
the design to what looks realistic for that era.
Been there done that. Mine was 2901 based Z80 clone
with hybrid uCode
wide bus and extented instruction set... Still didnt run any thing useful
on it, too big, too hot and far to weird. It was a good learning tool
depite all that.
This is what this is -- a hobby/ learning tool --
If it was $$$ making I would have to move to Seattle. :)
