[MRCA] MA4230/4231 Morse encoder/decoder

[Al Klase]

Eugene,

Looks to me like you can count the cells right through the shrink wrap.  
NiCd's a good guess.  Multiply by 1.2 volts per cell.

I removed it anyway since it was clearly original to the unit (Soldered in place).  The 4231's battery however, was leaking. Fortunately, I got the battery out and nothing was obviously affected.
