Cheap Microcontroller Programmer

Archiver

I am trying to find A circuit and software that can easily program a
68HC705J1A. I don't want to pay BIG bucks to buy one. I have seen
EZ circuits that will program PICs before...will they do this chip as
well? I ask because I want to make the PC keyboard interface in the
July issue of Poptronics and it needs that 68HC705J1A chip to work.
Then I can use a PC keyboard with my BS2! :-)

If you can use a 68HC811E8 you can program those in bootstrap mode very
easily. Cheap PIC programmers won't do it. Some "universal" programmers
might but those generally cost money. Just as an aside, our PAK-VI will also
let you use a PC keyboard with a BS2 or any thing else. It has two modes:
you can get ASCII characters, or you can get raw codes. The ASCII set is
extended to give you some function keys, etc. It will also read a PS/2 mouse
with the right program.
