Thanks to you guy's posts and Mili's instructions, I finished the first of 3 430 mods.
Couple of things I learned...
I used unwink's JTAG board and put a right angle db25 connector on it.
Turns out his disclaimer about the extra pin holes to allow this is for good reason. The right angle connectors pins are a mirror of the correct pin-put. I got 0xFFFFFFFF every time, even with the receiver powered off, because the connections were backward. I got a straight cup-type DB25, unsoldered the right angle, replaced it, and still got 0xFFFFFFFF, but not when the receiver was powered off. Then I got the 0x00000000. This seemed to indicate the JTAG was OK and I had another problem.

The other problem was while trying to make the backward version work, I had set the parallel port in the BIOS to Bi-Directional. Set it back to EPP, and it flashed like a dream.

Need some help, though. Two of the receivers including the one I have finished are 430RG. Just to see what I am facing, I opened up the 430RGA.
There is a yellow mark across the chip number.
Alchohol will not take this off, and I am afraid carb cleaner will take the chip number off along with the yellow mark.
Attached is a pic. Any suggestions?

Looks like the M28W, but can't be certain, No problem tho, just hook it up and try to erase it, if it won't it's a M28W, if it will it's a M29W.......go from there......

Thanks skinerd.

After a little sleep, it occured to me to check STM's site. They do not show an M28W320DB, so maybe I lucked out.
I do have a few more random questions, though.

I will cut the trace by the 8 solder pads to the left of the 5518. I have seen you mention in several posts that the RGA has a ninth pad, but I am not clear on where it is or what to do with it?

Should I have a preference between JKEYS 2.9.9 and 2.9.10?

I used nozktdrd430a_2_04 and it took me a few minutes to realize what the i on the screen was. (my first winked receiver)
Is there an new unwinked version suitable for the RGA? If I can turn it off on ch499, should I care?

Have you ever seen a parts list to populate the little cut-out at the front for the RF remote? Sounds like changing byte 0 on the eprom to 37h will enable it.

And lastly, I am under multiple spot beams. I saw in a post where some receivers can have the 900 locals enabled. Are any of the 430s in this category?

The 9th pad you mention, cut between it and the other one, same trace.....
RF remote also requires some additional on board conponents....
430s only receive locals 2-99...

OK, I see what you mean. I had already cut the trace from your jpeg, but now I see how it is the terminal end of where I cut. This is FAR easier than removing the board. Still tight, but I like it like that.
If you are in a position to post a list of the RF components, I will hit Mouser and give it a go.
