Data I/O manual sought

The manual also indicates that updating from V05+ requires changing the EPROMs and PAL, updating from V02-V04 additionally requires changing the resistor, and updating from V01 additionally requires a daughter-board swap. The main board in my 29B (V5.0) appears to have seven EPROMs and three bipolar PROMs. So I don't know if updating the mainframe firmware is just a matter of installing new EPROMs, or whether one or more of the bipolar PROMs (and maybe some other hardware) must be updated at the same time. Perhaps someone has a Firmware Update Kit manual for the mainframe and can confirm what is included. -- Dave
