@arstechnica Remember that the Zilog ez80 is also an 8 bit chip with 16 megabytes of address space and a clock speed of up to 50 megahertz, although because of its triple pipeline the programmer can take advantage of up to 150 megahertz of logical clockspeed if you use SRAM running at 50 megahertz.
@arstechnica I owned three generations of computers with the Z80 microprocessor. My first was a TRS80 Model I, with 4k and then 16k. Then a Big Board CP/M machine with 64k. Finally an Epson QX-10 with 256k.
In retrospect it's pretty strange that a microprocessor generation lasted that long.
Of course everything was very awkward in the transition from 8-bit systems to 32-bit ones.
