all the pram batteries are removed from my computers

(no battery = no leak)

i have to many computers to put a pram battery in each of them

for the fiew who need a battery to start up (macintosh II, IIx, IIfx, ..) and the ones with a bad accessible pram battery location (IIci, IIcx, ..)

i use a (or two) mono mini jack (female) at the back of the computer - hole drilled in and attached to a replacable clamp (never in the case of the computer)

and a male mono mini jack at a battery holder (different color of the mini jack for different voltage)

so i can attach effortless the 'removable pram battery' for the time needed or wished
