I am looking at buying the ISP1160 chips and doing a little PCB that has the USBWiz and TTL level in/out for a short run - would probably not cost much more than the retail price of a USBWiz board to do. I'm just checking it out - no promises, but I am thinking other computers may want/need the exact same thing, so spreading the costs benefits us in the QL community - like the 40FL220 battery adaptor affects a few other computers and systems too - I have already been emailed by someone who is maintaining 70s Siemens automation equipment in a plant in Germany who wants 100. :)
