A caveat regarding firmware updates: while I don't have a Firmware Update 
Kit manual for the mainframe, the corresponding manual for the 303A-011A 
adapter indicates that the V11.1 kit comes with four EPROMs, a PAL, and a 
resistor.  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.
