I picked up a pair of T3020 DES KVLs today, and have a suspicion they may have been upgraded based on some comments made by the seller.
They're marked as BX models. Each has a double board (I've heard some KVLs have three). There's a label "TRN 4974A" on one chip on the second (i.e. not mounted to front panel) board, and there is a single 28 pin socketed PROM, marked 27M69 8507. There is a small board in the bottom of each that looks like a hybrid - part number TRN4836R, date code (?) 8621 on one and 8661 on the other.
What do I have here? Are they upgradable to CX or (preferably) DX? What's involved? I've seen a few vague comments in past threads, but nothing concrete. It would be nice to be able to load my Systems Saber, my Spectra and my Astro Saber.
Thanks!
T3020 KVL - how do I tell if it's already been upgraded?

um, dude, check out the primer on batlabs main board....they only go to `BX' model, never was a `CX' or `DX' version, the T3011 took it over as it could do both the DES and DES-XL. The 3020 will never do anything but DES. I have a good one if you want a spare for $75.00, no batt or charger, but looks really nice.

Threads like http://batboard.batlabs.com/viewtopic.php?t=12796 have led me to believe they can be upgraded...

Further info -
The top board (not attached to faceplate) has a sticker "TRN4974A" on U103, and is stamped "TRN4835A" on the other side. The other board (the CPU board?) is marked "TRN4834A" and has the 28 pin PROM socket but no 8 pin socket. The hybrid is soldered in place.
What the heck do I have here?
