Re: TT030 Clock Batterie
The TT’s clock battery is 6 volt and not 3 volt so the CR2032 won’t run it correctly.
It’s better to get a 4xAAA battery holder and solder the original leads to it making sure that you have the correct polarity.
I’ll post a picture on mine later.

Added code to the MiNT kernel (still there the last time I checked) + put together MiNTOS.

Re: TT030 Clock Batterie
I thought the original TT battery was a Tadiran TL-5242/W, 3.6V Lithium
EDIT: Just checked my TT and I had indeed replaced the original with a 3.6V which has been working fine
I used one of these cheap Xeno batteries and just swapped the connector to match the TT.

Re: TT030 Clock Batterie
Do some have 3.6V and others 6V? My TT's original battery was most definitely 6V.

Re: TT030 Clock Batterie
@stephen_usher it seems the RTC chip is rated at 3V - 6V.
Re: TT030 Clock Batterie
Perfect thx for the tips I think is my problema CR I get 3.2v and I need 3.6v . The original one is a Aa rated 3.6v now what tool you use for adjust clock time ? And with the bat can power the internal speaker ? This one is not get sound. I tested the speaker with a Little aa bat in positive and negative and I get sound. Regsrds

Re: TT030 Clock Batterie
Older ATARI TT have a 6V Battery (PGA CPU) and newer with SMD CPU have a 3,6V Battery ...

Re: TT030 Clock Batterie
The speaker doesn't need the battery in there but you may have lost the volume setting in the NVRAM.
I just set the clock using XCONTROL.ACC as you would on an ST.
By the way, this is what my battery pack looks like:

Re: TT030 Clock Batterie
Nice adapter but with 3xaa bat is like 4.5v mine is apparently 3.6v. I tried to use xcontrol the volume is right but the weird stuff if itry to change time I can enter the new time but can't escape from this , the only way is power off. I try to make a video for show . Regards

Re: TT030 Clock Batterie
As noted earlier, the clock chip can handle 3.6V - 6V so they're both fine.
My one is actually 4xAAA batteries, so 6V, as was my original lithium battery pack.
