As requested.

Will post 'my' version shortly.

Attached.

Note that I have only implemented the four signals required by the current ISP parts, RST,
SCK, MISO and MOSI.

Can't see start of this thread but recently came across this AVR dongle.

Seemingly not compliant with Atmel's recommendations for the AT89S5x. Wrong ISP
header pinout for example and different pins on the parallel port.

Yes, that's for the AVR, not the 89S5x

Why they had to make several incompatible versions of an ISP program and
hardware is beyond me.

Ooops. Wrong micro.
Just moved to the excellent AVR stuff, still learning. Due to build that AVR
dongle but was given a dev' setup. As well I didn't.
