I have had my pair of IIGS for about 10 years and never looked at the batteries. In fact, both have been sitting in my closet for the last 4-5 years untouched.
One is a ROM01 Woz (upgraded firmware) with Varta battery date coded 0686 - 3V, now about 0.1
The other is a ROM03, Tadiran TL-2150 battery date coded 0889 - 3.6V, now about 0.7
The good news is that neither one of them were leaking or corroded in any way! I was surprised. Replacements are on the way...
Hello! I was never an Apple guy but got a wild hair a few years back and picked up these, a Performa (no idea why), and an Apple ][ Plus and a IIe.
I repaired what was dead and upgraded where I could - no idea on the current specs on the IIGS models because I can't recall what I did. But, both appear to have CF card readers (two different models) and a RAM upgrade installed.
On the II Plus, I have a bad keyboard so at the time (2013), I built a PS/2 to apple adapter and was happy to have a working computer after replacing a few bad parts otherwise. The IIe arrived working - boring. I fiddled around with appletalk and was trying to hack up a working version of a linux-based daemon for them before I trailed off.
Now, in 2022, I discovered Ben Eater's videos while on sabbatical from being employed. So, more 6502 crap to come.
I was a bench tech by trade in olden times (80's) but now do all facets of IT. Sometimes it's good to get your hands dirty with the technology again!
