Can a T3020-AX be converted to a T3011-DX in any way?
If you replace the EPROM, add the serial EEPROM and the hybrid?
Are the main boards common ?
T3020-AX (DES only KVL) Conversion?

I disagree that buying one would be better than making one if its possible to do so. For an already owned 'loader, a hybrid and firmware chip are pretty inexpensive and perfectly adequate for most users.
I have heard that you need a BX or better to upgrade to DX. I thnk this has to do with the EEPROM slot not being socketed(?). I've also heard something about certain DES only loaders (AX, maybe?) not being able to be uplifted to -xl. However, I've never confirmed either of these.

The only models that can be upgraded to a "DX" with a firmware change is the CX. If the AX & BX models have a main board with dip switches, it's NOT upgradeable............If they don't have dip switches, it IS upgradeable with the proper firmware chip change-out.

My recollection is that BX could be upgraded to CX. This upgrade required drilling a hole with a Dremel tool and changing the EPROM. After this upgrade was done, the KVL was capable of all functions except for "remote KVL" (KVL dials into KMC using a dial-up modem) operation. Since CX could be upgraded to DX, I think that BX to DX is also possible.

Do you have exact procedures for that? Where to drill some hole, and why? I guess the main problem is the smaller EPROM in the older KVLs, and I guess this can be solved by wiring the bigger 27c256 EPROM directly to the CPU with the additional address lines.JohnG wrote:My recollection is that BX could be upgraded to CX.
