Whn I got up off the floor laughing... The z80, 8085, 8080 are all 40 pin
packages and the z80 in any varient was never in a 48 pin package. The z180
aka 64180 was a 64 pin package or 68pin plcc.

Not true. there were z80 based boards to replace the 8080 board. For a
while due to costs there where boards that carried z80s that would plug into
an 8080 socket to upgrade the machine to z80 perfomance...

What you missed was the ti9900 chip that was 3 years older and also 64 pins.
FYI the ti9900 chips was a 16bit cpu!
