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

[Vladislav Korotnev]

Only one slot, only on batteries, only non standard cards and intermittent behavior? Sounds like a degrading capacitor issue to me IMO

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.
