82mumble WOM (write only memory) april first version.
Oh, she's good. She's very good. You're right, and I did. The number of components
turns out to be fairly
ugly, although they can still be made to fit in a fairly small area --
although we'd need robotic assembly to place all the stuff -- and that's
assuming I didn't grossly screw up this design. Maybe I should spice it... ;-)
;) designing with tubes or transistors is different and I'd bet if I
looked at the design I could trim out unneeded inversions or maybe by
adding an inverter use wired NOR logic instead of AND or NAND.
Mind games like this are fun at times; they remind us
that, at least at times,
the more things change, the more they remain the same.
That and it takes up back to the core electronics that makes it happen.
Myself I'd love to see three designs for a simple but useable if not
useful cpu one using MSI logic, one using SSI TTL and a simple buildable
transistor design (serial for simplicity).
In every case the memory can be modern or if something like serial
memory (drum, disk or delayline type) could be done with moden parts for
sanity sake.
