Download a Hi-Res Version
(1427x502)

Processor: 030@25Mhz
FPU: 68881 @ 25Mhz or 33Mhz, or 68882 @ 25Mhz or 33Mhz
MMU: Internal in 030
RAM: 2 or 4MB (32bit) (256K ZIP Chips)
32bit expansion slot for additional RAM such as DKB 2632 card

NB. You need ROM Rev 6.6 but preferrably 7.0 to use OS2.x+, however there may still be starup problems when running under OS 2 or AMIX

On the A2630 card there are four jumpers near ROM :

                           ______________
                          |              |
                          |              |
                          |              |
                          |______________|
                           ______________
                          |              |
                          |              |
                          |              | 
                          |______________|
  Off  Off  Off  Off 
  o o  o o  o o  o o

 J302 J303 J304 J301
   ^    ^    ^    ^
   |    |    |    l_ = MEG4, ON for 2Megs, OFF for 4Megs.
   |    |    |
   |    |    l______ = B2000, OFF normal, ON for old A2000 w/68000 removed.
   |    |
   |    l___________ = AUTO, OFF ram is autoconfig'd, ON ram is disabled.
   |
   l________________ = OSMODE, OFF autoboots AmigaDOS, ON autoboots UNIX.




There is also a jumper under the heat shield between the 68030 & 68882.

         On
      o o-o
      3 2 1

      J202 = ON 1-2, 68882 FPU uses same 25MHz clock as 68030.
             ON 2-3, 68882 FPU uses separate oscillator added in U203.
