Info is taken from December 1988 issue of Popular Communications:

the diode # to be added is D510 (if there's a jumper present - remove it)
polarity should point towards the cpu chip.

now instead of 30 channels in each of the 10 memories banks you'll
have 40 channels.

I read some other mods in other issues of Pop com and in 73 i'll
post the after i find them if nobody beats me to it

73 from a non-ham (hopefull a novist soon -- just need the code)
posting his his first post and not knowing if it will work.
