[TenTec] Giehl Chip Versions

[Jim Bull]

Jerry,
My "understanding" of Jack Giehl's chip is that the version he provided 
to a Paragon owner was directly related to the TT ROM version as 
delivered from the factory.  My early Paragon had a 3.8 version and this 
was replaced with a Giehl 3.1.  My later Paragon came with the TT 4.0 
ROM and this was replaced with a Giehl 6.1 version.

As I am not a CW buff, I really can't address the CW/QSK timing 
issues...Never really cared!!!

I also never "broke the code" on date of manufacture, so I'm no help 
there.

I will say that the Giehl chip as installed in the Paragon is (IMHO)
much more efficient relative to tuning rates/memory storage/display 
settings/Voice board operation as compared to the original TT ROM and 
again (IMHO) will run circles around the Paragon II ROM, which I 
personally feel was produced by TT as an answer to Jack Giehl's HARD 
work on the Paragon software.
