Notes about the Amiga version...

The amiga version lives here:

I took David Tait's PP software, and I ported it to the Amiga. I
compiled it with DCC 1.10 on an Amiga 1200 with 030@50MHz and 882@50MHz,
and I tested it with the Maplin PIC16C84 Programmer (order code LU29G),
but I believe it should work with just about ANY Amiga and any
PP-compatible PIC programmer.

EXCEPT...

Due to, essentially, a hardware limitation, it's not possible to read
back data on pin 10 of the Amiga's parallel port, because it's a CLOCK
line, not a DATA line. This means that the Maplin PIC programmer isn't
usable, on the Amiga without modification, in theory.

To get around this, I've used a slightly modified cable. Don't panic,
this is the least of your worries! If you've already got a PARNET cable,
you're most of the way there. Basically a PARNET cable connects pins 10
and 13 (pin 13 CAN be used as an input). The original PARNET
documentation shows this cable:

            (2-9)   D7-D0   ------------    D7-D0
            (12)    POUT    ------------    POUT
            (11)    BUSY    ------------    BUSY       PARALLEL PORT
            (13)    SEL     --+------+--    SEL
            (10)    ACK     -/        \-    ACK
            (18-22) GND     ------------    GND  (18-22)

However, I found the maplin PIC programmer was using pin 25 as a GND.

This isn't a problem, just link together a few more ground wires.
This doesn't require any more cores in your cable, just a few more
tags soldered together in each DB25 plug:

            (2-9)   D7-D0   ------------    D7-D0
            (12)    POUT    ------------    POUT
            (11)    BUSY    ------------    BUSY       PARALLEL PORT
            (13)    SEL     --+------+--    SEL
            (10)    ACK     -/        \-    ACK
 CHANGE! -> (18-25) GND     ------------    GND  (18-25) <- CHANGE!

The great beauty of this is that this cable CAN STILL be used for
PARNET - you've not ruined it, you've just connected a few more of
the GROUND wires. If you don't already have a PARNET cable, you now
have TWO excuses to make one! You've also not had to make ANY
modifications to the Maplin PIC programmer, so you can still use it
on your mate's PC if you really must.

I AM NOT charging a shareware fee for this or anything, but I WOULD
like you, no, I DEMAND that if you get this program working, you email
me telling me what Amiga and what PIC programmer you used it with.
If you haven't got email (what do you mean you haven't got email? The
21st century is only just around the corner you know! hurry up!), then
statistically, one or other of your neighbours will have, either at
home or at work. It can't be that hard to get SOMEONE to send me a
quick email. That is ALL I ask for my efforts.

My address, for the purposes of this "emailware registration", is
nick-app@leonet.co.uk

So that's it! Happy PICing!
