Looking for DECtalk DTC-01 v1.8 and other non-v2.0 firmware roms

I know that the original vt240-molded-case DTC-01-AA DECtalk had multiple firmware versions, but all units I've ever seen have had the v2.0 (i.e. the final) firmware installed. I know at least version 1.8 existed in older units, and was wondering if anyone here has a DECtalk DTC-01 with firmware 1.8 (or any version other than 2.0) in it. It should speak "Dectalk version x.x is running" when powered up. Bill G. had or used to have a v1.8 unit, but I can't manage to get in contact with him and I don't know if he still has it. At least one other person on usenet had a v1.8 unit where the eproms all bitrotted to blank after a while. P.S. I'm also hunting for DECtalk DTC-03 (decmodem-rackmount) firmware versions; there are at least three, maybe as many as six different firmware versions for those cards. -- Jonathan Gevaryahu jgevaryahu at gmail.com jgevaryahu at hotmail.com
