The attachment that I've send to the PICLIST group Included the David
Tait version with a few hardware and Bugfixes. The Guy who fixed
them Robert Farrer from Farsoft Computers included David's Copy Right
Notices and redesigned his hardware layout with Notes on the Fixes.

For more Info you can mail me Directly. Farsoft is not available on the
Internet but is on a local 14400 Modem Bulletin Board and I've Got most
of their stuff on My PC. I've got a propoasl from several guys to make
use of their FTP sites to uoload the software. I'll speak to Robert and
see if we can arrange that. He's converted most of Microchips samplecode
to run on '84's as he also does a course on PIC micro's wich is very
efficient. People with no experience can learn in 6 weeks to be quite
efficient programmers.

Let me now if there's interest and I'll forward all the requests to him.

Thanks.

Jattie van der Linde.
