[Elecraft] K2 with MacOS Classic

[Michael Babineau VE3WMB]

Bekir :

One additional option may be to put Yellow Dog Linux on your Powerbook
3400. Having Linux on the machine may open up some additional options
to you. If you have enough disk space you can set it up for dual-boot
(Mac OS / YDL ).

It looks like older versions of the OS up to V3.0 support the hardware 
and it is likely
the newest version still does as well.

I have YDL V3 running on a old Performa 6360 and it runs pretty well.

It is likely that you can find a cheap copy of YDL V2 or V3 on Ebay
for about $10US.

Best of luck,

Michael VE3WMB

P.S. Both TLF and xlog (linux logging programs) support the use of
hamlib which would allow interfacing to the K2.
