Re: [hatari-devel] HW support matrix for manual

[Eero Tamminen <oak@xxxxxxxxxxxxxx>]

Hi,

I want to list HW differences between Atari
machines emulated by Hatari, so I'm opting for
listing different Shifter versions, and option
for upgrading CPU for ST etc.

(Shifter variants could be listed on one line
with "ST, STE or TT Shifter".)

I'm still wondering should I list also joypads...

Any more comments?

Atari HW configuration differences matrix
-----------------------------------------

Table below lists HW features belonging to each Atari machine, except 
for the ones common to all
(FDC, IKBD, MFP, MIDI, PSG, RS-232...).

x = Stock machine configuration
[1] Requires EmuTOS or TOS 2.06
[2] Requires EmuTOS or Linux
[3] Add-on, supported since TOS 1.02
[4] Some features missing from Hatari
[5] 68030+ is add-on, requires EmuTOS or TOS 2.06
[6] Only partial support in Hatari
[7] Hatari patches support for this to TOS v4.04

(512k version of EmuTOS included with Hatari binary packages supports 
all Atari HW except
for Falcon DSP & Videl HiColor mode.)
