[aprssig] Need EPROM Burned

Yeah, it's easy to read and clone an EPROM.  I'm assuming if you have 
the two TNCs that came with the ROM, the manufacturer couldn't really 
complain.

I do have a stockpile of 27C256's, one-time programmable types since 
it's not worth shipping them back and forth to be erased.  They're free 
for UIDIGI users, $5 for any other hex code you want burned.

If you need one, order now 'cuz I'm out of here on Tuesday morning and 
won't be back until the middle of next week.  My lovely assistant Tory 
will be packing all of the orders she can, but running the EPROM burner 
isn't something she's learned yet, and its mangled English prompts 
aren't exactly self-explanatory.  ('Slowness' is one of the speeds, a 
box simply marked 'Yes' starts the programming...)
