The big difference between the 5 and 6 is the CPU.
The 2006 uses a faster CPU for quicker scan times
26cps vs. 13cps, if I recall correctly.
Aside from an extra bilateral switch in the 2006's
squelch circuit, both are identical.
Later versions of the 2006 use a light switch instead of
a dimmer to conserve the EL panel's life.


Both my 2005s scan at over 20cps - but I did cut the diode which slows
down the scan speed.
