Hello. I am hoping to find out about a device. I recently purchased an Apple II. It had some device plugged into the game port on the motherboard. I am assuming it is some sort of clock device. It says:
"GLANMIRE ELECTRONICS LTD 1982" and "MICRO WATCH".
It is about 2 inches by 2 inches. It has a Berec Memtec battery, 3.6v 100mAh
Any ideas on what it is? The battery leaked and ruined it, plus one of the pins rotted off and broke inside the 16-pin socket. :-(
Thank you.
A little Googling found this.
THANK YOU very much. It looks like it was a pretty cool device. I hate that the battery leaked and damaged it.
It might be salvageable. But probably doesn't have much support, e.g. a ProDOS driver.
There are plenty of other clock options for your machine if you want one.
Can you post a photo?

I'll try to get some pics up in the next couple of days. I am just investigating what I have. I think it is an Apple II, not a Plus. I have never had a real II, so I just want to slowly over time check it out before firing it up. I have the other II models, just never got lucky enough to find a II for cheap.

It may be possible to clean that up and save it. It should be possible to re-create it with a new PCB and parts, especially if the NEC chip on there can be identified. Most of the other parts look like they can be identified. I bet the NEC part is a common clock chip though, so probably not too hard to figure it out.
Cute little board. It's so simple, you may be able to just jumper any traces that are bad.
Did the battery leak make it to the motherboard?
I will have to check it more thoroughly, but so far, I just know one of the pins broke off in the 16-pin socket.
