I have a few PHILIPS 8031 chips in 40 pin package. They cannot be programmed with Flashmagic most probably because the bootloader is corrupted. I looked at a few Universal Programmers on ebay etc. but most of them are beyond my budget and some do not support the PHILIPS chip.
If anyone knows of a parallel programmer circuit which can be fabricated at home on a protoboard, please post the link.
In case there is no solution, I am planning to go for the one at ebay
This one has a demo mode to get a feel of the software without the hardware being in place. Also the firmware can be upgraded as new chips are added.
Cheers.
