I had two of the old Picaxe 14m chips - one operating in a circuit and one for a spare. I attempted to program the spare and got
the 255 error so I threw the chip away. Later I pulled the working 14m and got the same results.
I moved the programming station from a Dell Inspiron 600 to a Shuttle XPC computer and had no problems programming.
This was the first time I had attempted to program one of the old chips on the Dell PC, all my M2 (08,14,18,20 and a 20X2) chips program with no problems.
This tells me that the USP ports on my Dell PC supplies less power than the Shuttle PC. Do the old Picaxe chips require more power
to program(how much is enough?) than the new M2 devices or am I living on the hairy edge when using the Dell?
