> A significant revision of the index to internal parts and firmware for 
> the Watkins-Johnson DSP series of receivers (i.e. WJ-8711 family) is now 
> maintained on my Watkins-Johnson website.
> 
> I've exhausted every document and radio I own to develop the document 
> section of this index. For continued expansion, this project is now 
> dependent on information sent by owners of these fine radios or from 
> documents they have for them. Information from manuals covering earlier 
> non-A versions of the HF-1000, WJ-8711, and WJ-8712 or any version of 
> the WJ-8723 would be particularly useful.? Many thanks to those who have 
> already sent information.? If you submit information and do not want

> If you are willing to contribute, the most useful way is to pop the top 
> cover of your radio and copy the numbers you can find on controller 
> board for U1 (68HC11*** processor), U12 (processor EPROM, U37 
> (DSP5600****), and U56 (DSP EPROM) as well as the model and serial 
> number from the rear panels. If in doubt, copy all the numbers on these 
> components and I'll sort them out.

> The easiest way to contribute if you own a WJ-8711 or WJ-8712P, is to 
> copy the firmware number, which displays at boot up. Also copy the model 
> and serial number from the rear panel.
> 
> The board numbers are very useful. There are WJ boards floating around. 
> Being able to identify them and knowing what and where they can be used 
> will help populate the pool of available components for maintaining 
> these now discontinued receivers.
> 
> The board numbers can be found along the edge of the circuit boards and 
> typically start with 14632ASSY followed by a 7xxxxx or 9xxxxx (14632 
> being the CAGE code identifying the manufacturer, i.e. WJ). On several 
> versions, the board ID numbers are along the rear edge.
> 
> If you have copied the hex or bin files for the two (or 3) EPROMs U12 
> and U56 (and front panel A1), I am quietly assembling a library of 
> firmware. Once the question of intellectual property is resolved, I may 
> be able to post these on the website. Currently for U12 I have 
> v04.01.01, v04.01.03, v04.01.10 and for U56 v03.00.01, v04.02.05, 
> v04.02.07 and for A1 v3.1.21 and v3.2.0.
> 
> Please note that a driving factor in all this is documenting which 
> firmware versions can be used in which versions of the radios. Though 
> the last versions, v04.01.10 and v04.02.07, are widely considered to be 
> be the most desirable, many of the older boards and radios will not work 
> with these versions.
