Am 1 Sep 2006 15:19 meinte Peter Turnbull: It seams as if this also shows a migration trend, how certain technology levels move into applications. While a Z80 (or other 8 Bit general purpose chips like 6800 or 6502) where desktop CPUs in the late 70s, they became the choice for embedded systems in the early 80s, then in the late 80s highly enhanced versions (read wit lots of additional perhiperie) moved them into consumer products and total volume markets. where they lived well until the mid 90s. Similar 16 Bit 8088/86 CPUs moved in the Desktop in the early 80s, moved into embedded in the late 80s, where 186 systems where still big the late 90s ... to be replaced by 32 Bit Systems like 386/sx/sl/486. And now the Pentium does it. Gruss H. -- VCF Europa 8.0 am 28/29.April 2007 in Muenchen http://www.vcfe.org/
