Mike Willegal, a member of
the Applefritter community at applefritter.com, is - besides Tom
Owad the leader of the applefritter platform -
one of the most refered experts to the Apple-1. He released the
most common replication of the Apple-1 - the MIMEO and he has
his own
site with dedicated information to the subject of the Apple-1, that
also bears the only public availiable list to all known
originals of the
Apple-1 including their documantation.
Everybody who wants to get familiar with the Apple-1 computer will
stumble sooner or later across his website
http://www.willegal.net
which contains huge amounts of valuable information on īthe topic of the
Apple-1. He also distributes a set of parts and PCB to rebuild
the Apple-1 Cassette interface and included in the set is also the set of
the 2 proms which are required for proper operation of the ACI.
At his page he mentioned besides information to the ACi also a bug
discovered in the Software of the ACI.
If you intend to build a replication of an
Apple-1 independent from which of the existing PCBīs it is
highly recommended to visit his page about the ACI
(
http://www.willegal.net/appleii/aci.htm ) and to purchase a
kit from him. Only ordering the PCB is not a good idea because
finally when assembling the
PCB - you will find out that there wonīt be any other source for the
requested proms. Besides the set is not expensive at all in
relation to the PCB itself
and the fact that also time is required to program that proms ( not to
talk about the needed equipment for programming that chips... ).
If you want to examine the ACi tough then the
oscilloscopepictures at his page will surely also help you
ahead.
