Sorry about the crappy flash reflection

Roland SH-2000

It's not a Roland SH-1000, but almost ;)
I serviced an SH-1000 for a colleague who also had an SH-2000 that he was willing to sell.
His SH-1000 needed the keyboard contacts cleaned, so I took care of that and got the SH-2000 for a good price as "payment" :)

Roland CR-78 non-rechargeable Lithum battery replacement mod

Replacing NiCad with Li.

So, I was servicing a CR-78 for a friend and the old leaking battery had already been removed when I received the unit. After I was done with replacing all the damaged components I was going to put a non-rechargeable battery in there. It's probably possible to replace the NiCad with a NiMH battery, but they recharge slower than the NiCad (so you need to keep your machine running longer and more often to keep it charged) and I'm not sure exactly how they work when they reach their full charge.
As I'm not an expert in rechargeable batteries, I decided that the safest option was to use a non-rechargeable Lithium battery.
