I'm not so sure they were really available, though. Take a look at

I was going to say I thought the Z80 was no longer in production,
although some of the descendants are. However, Zilog still show
several 40-pin DIL and 44-pin PLCC versions as active.
Intel still list a couple of members of the MCS-48 family and sell
modern versions of the 8051 for automotive applicatons. I think MCS-51
is mid-1980s though.
