[hatari-devel] Fwd: Atari TT memory configuration

[Eero Tamminen <oak@xxxxxxxxxxxxxx>]

Hi,

Btw. I noticed from Wikipedia that Atari TTs had 2-12 MB of
ST-RAM, not upto 14MB as supported by Hatari.

When I asked on debian m68k mailing list about typical TT
memory amounts, this was the answer:

Should I use above information to fine-tune test memory amount
in Hatari's TOS bootup tester?  I.e. do TT tests with 2, 4 & 10 MB?
