Same applies to HP-34C. Eric's preferred method for getting the ROM dump was invoking the calculators selftest, which reads all ROM addresses subsequently to calculate the checksum, and recording the opcodes with a logic analyzer. Unfortunately the HP-29C didn't have a selftest. But I remember he mentioned to me that he had dumped all woodstocks, because he also used more invasive methods to get the ROM codes.
