If you can control an external I/O port on the Amiga then you can write your
own version of the programmer control software.  You need to be able to
write to 3 pins and read from 1, and the programmer cycle timing for the '84
is not critical.  Get David Tait's QBASIC source code (or the 'C') and read
it.  You should find enough information there to write your own on the Amiga
(BASIC might be the most portable version in this case).  If the operation
of the code is not clear you might also ask Microchip for their '84
programming specification data sheet.

I took David's code in QBASIC on the PC for his programmer and modified it
to control the AN589 programmer using VisualBasic for DOS without too much
effort, then I made a Windows version of it with VB Windows.

The timing for the other PIC devices (EPROM and OTP) is more critical, and
therefore not as well suited to homebrew designs, however there is an
article in this month's 'Electronics Today International' (ETI) which
describes a programmer for the whole PIC range using an RS-232 interface (I
think, the magazine's at home).
