[Premium-Rx] WJ-8711-A 06.00.0x FIRMWARE QUESTION

[pat1mca at aol.com]

Greetings List Members,
Has anyone got a definitive record of what Firmware labelled 06.00.0x exactly does please ?
In particular  Eprom U12 Part No 905001-002  ver 06.00.04
This is paired with U56 DSP ver 04.02.07

I suspect it might be the usual late 04.01.10 but with maybe a 488 or 485 option ??? and runs on a 904978 A2 Control Board .

Thanks in advance. Please reply offline.
