[sdiy] Alpha Juno battery replacement

[Richie Burnett]

I initially intended to fit a battery holder in mine, but I couldn't find a 
pin compatible one.  There's also very little clearance between the 
components on the top of the main board and the keybed frame that it slides 
beneath!  In the end I just soldered another CR2032 with welded tabs 
directly to the PCB.  My local supplier had CR2032 options with short and 
long tabs, so I opted for the shorter leads to keep the profile down.

I did think about tucking the battery away somewhere else (more accessible!) 
on flying leads but if the new battery lasts another 40 years it will see me 
out.

-Richie,

I've been saying for 30+ years that someone like Keystone Electronics needs 
to make a

retrofit CR2032 battery holder that has the same lead spacing as the CR2032 
batteries

that have spot welded leads.
