So, did some experimenting today. Turns out, the flash routine for the SBEC-II is exactly the same as for the rom-aided SBEC (which is the protocol I'm using for the flashable SBEC modification). So, short story - I can read and flash SBEC-II's on the bench. I know a few guys had asked about modifying the '92 T3 cal (and T1). It looks like I could do them now, at least minor mods. I'm not near ready to make a 3-bar version yet.
