[NTLK] Newton 2100 on batteries only freeze with ATA or 3rd party linear cards

Vladislav,

It may be that, but who knows where this capacitor is?

What I discover today is that if I work on AA batteries only (new ones, indicator shows me 90%), and I try use ATA memory cards or non-Apple linear memory cards (in this case was 20MB card), my Newton just freeze very bad. Even reset button is not working. The only option is to remove batteries.
