Great!  But now I'm a bit confused.
I see two EPROMS a HI and a LO.  I thought
It only used the LO unless you installed special
DIGI firmware.  But maybe I'm thinking of the TNC2's.
So I guess I need both.  Let me know how much you want.
I see my other firmware is 7.0 and not sure what vers I
Downloaded but I can send the .hex file as an attachment
If you can read it.  It's possibly newer.

Can't get your direct e-mail address from the list,
So shoot me a reply directly at

I have a PK-232MBX.  I can read my EPROM and put it into a 27C256 for you.
If your version is 
newer you would need to send me your EPROM so I can read it in.  I will do
it for $5, this will 
cover my cost of the 27C256 and first class postage back to you.
