[GreenKeys] Flesher TU300 to TU470 question

[Jim Pruitt]

Back in the early 80's I bought a Flesher TU300 kit and put it 
together.  I don't think I ever used the converter after I built it.  I 
kept hoping there were mods to convert it to the TU470 (yes a 
dream--pipe dream maybe).  I still have that converter.  Can it easily 
be upgraded to a TU470 or is it what it is and will remain that 
forever?  As I recall I bought it from Crown Micro because Flesher did a 
number on them and paid them with inventory rather than money.  I 
thought Flesher went out of business then as I never saw anything else 
from them but someone on this list a month or so ago sent a link and 
Flesher is alive and well...but not in the RTTY converter business 
anymore.  As I recall their business now is making and selling book 
binding machines (I thought books went the way of the dinosaur) or 
something like that.

Is the TU300 even worth bothering with?  How does it compare to the ST6 
(and ST6000) and similar?

Thank you.
