I have built a circuit (poptronics & PE Jan 86) by Robert gotchall. the asm file from gernsback has errors mostly due to a missing include file that is different from the std microchip file that was not in the download. There are also errors such as portb defined as port_b etc. and some registers that are not defined. Does anyone have one of these working and can supply the error free code?? or any other solution?? such as Robert Gotchall are you out there???
