Lez Anderson is very keen on encouraging people to get
into electronics and hardware design in particular. To that end,
in early 2014, he made additional "kits" of parts available to a number of
members of the Memotech Forum
who expressed an interest in getting one (the "offer" is now
closed).
These kits contain a
range of very useful and interesting ICs - they are not old
parts that Lez happened to have lying around, they are "new old
stock" items that Lez bought from China to
give away to the group. A real big "thank you" to Lez
for this generous gesture.
I'm looking forward to seeing what uses the lucky "winners"
can find for this impressive selection of chips. In due course,
if you would like to share your achievements, I'd be happy to
post details on the website in
this area. In
the meantime, to kick things off, you can see Bill Brendling's
Z80 computer design from the 1980s by following
this link.

Updated Parts Kits From Lez in March 2014 Click on the IC
part number to open the component datasheet
Most of the other
links are to Wikipedia to explain the acronyms if you are
unfamiliar with them. |
All of the PLCC and most of the DIP
packaged chips are already in sockets. Kits also
include miscellaneous items, including
crystals, LEDs, switches, various connectors and an
IDE
Compact Flash card reader.

Original Parts I Obtained from Lez in 2012
These are the components that Lez sent me as part of his "FREE Z80
stuff", subsequently, Lez sent me many other components and
useful items - thanks Lez!
If you received a kit of parts from Lez
in 2012/13, it is probably
similar to this - your mileage may vary of course :-)
