The 34c ROM is included in the nonpareil package though. So maybe Eric simply didn't have a 29C to dump the rom.

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.

That's one small step for a man - one giant leap for mankind.
