I do have most of the skills for this but would hire somebody for the precise drilling required. My AOR 8200 MK111 already has an option socket, but I have no idea what the input specs are. What the heck does fit in that option port under the power input? Is it possible to just get a generic cable to fit in it and get the other end into a USB port for the control? Or, maybe have to take additional steps to send the USB output to an RS232 Cable, then back to a USB male, then to a USB port? I strongly suspect no but had to inquire. I'm also thinking that because there are two different official, expensive cables for the AOR 8200 depending on the Blocked/Unblocked status and S/N, that this those cables have chips in them that would render my idea useless.
The original 8200 and the series 2 used an odd plug for the computer interface. The same plug was used by some HP Journada models so cables from those could be used with some butchery. Usage of the non-standard style connector is what now causes the problem...very few devices use it so no-one manufacturers it any more.
The series 3 initially used that same connector but later produced ones used a more standard type.
There is no 'chip' in any of the cables and there is no difference between USA blocked model cables and standard full range cables (the blocking was in the internals as required by your odd cellphone restriction laws at the time).
The cables come in two types
In terms of PC control for the 8200. The 8600 is essentially a desktop 8200 (better, replaceable filters, better component shielding and the like) so software designed for those will usually work with either unless the author includes model firmware checks so they can improve the gouge.
It is possible to solder directly to the internals of the connector but it's a real faff. When you take into account the value of your own time it's not really any cheaper than buying a cable. In my case the cable would be considerably cheaper than my time.
You could try searching the wayback machine to see if the old ar8200.net website was archived - that had full details of cables, pinouts, colour differences between AOR and HP cables, serial numbers for changes to the radios (such as modified shielding, change to pinouts, change to plug type). It also contained equivalent info for the 8600 and links to all known software for each and examples of excel control scripts to make frequency storage 'unlimited'.
