Interface
68000 socket
  • Prozessor Austausch Karte - Processor Exchange Board
  • developed by the editors of the german computer magazine c't
  • schematics has been fully published in the magazine
  • designed to emulate the MC68000 processor bus interface at best, so it can be used in Ataris and Macs as well
    processor
  • 68020 @ 12 / 16 MHz, PGA (asynchronous to the motherboard)
  • optional 68881 @ 12 / 16 MHz, PGA - runs at the same speed as the CPU
    memory
  • optional daughter board with four 32k×8 ROM or SRAM chips
  • two boards can be stacked on each other for 256 kB ROM / SRAM total
    notes
  • plugs into the 68000's socket
  • no 68000 fallback mode

Amiga
A500
Interface
68000 socket
  • successor of the original PAK-68 (Prozessor Austausch Karte - Processor Exchange Board)
  • developed by the editors of the german computer magazine c't
  • schematics has been fully published in the magazine
  • can be used in 68000 based Ataris and Macs as well
  • less error prone design - processing flow with state machines
  • the discrete logic had been put into GALs, allowing easy reconfiguration in case of timing changes
  • the GAL based layout is smaller, making room for ROM/RAM sockets which were located on piggy-back boards on the old board
    processor
  • 68020 @ 14 / 16 MHz, PGA
  • optional 68881 or 68882 @ 14 / 16 MHz, PGA - runs at the same speed as the CPU
    memory
  • four 32 pin sockets for up to 512 kB ROM / SRAM
  • when occupied with ROMs, access to OS ROM is 32 bit wide
  • SRAMs with 100ns or faster access speed can also be fitted but an additional decoder GAL is necessary
  • ROM access can be sped up by 40% by setting a jumper, which disables ROM synchronisation to the 8 MHz clock
    notes
  • plugs into the 68000's socket
  • either a 68000 has to be put on top of the board or an additional GAL has to be installed

PAK-68/3
Manufacturer
C't, Germany
Date
1994
Amiga
A500
Interface
68000 socket
  • third generation of the Prozessor Austausch Karte - Processor Exchange Board
  • developed by the editors of the german computer magazine c't
  • schematics and GAL equations has been fully published in the magazine
  • designed to emulate the MC68000 processor bus interface at best, so it can be used in Ataris and Macs as well
    processor
  • PAK-68/3-020: 68020
  • PAK-68/3-030: 68030
  • 14.3 MHz (synchronous) or 32 / 36 / 40 MHz (asynchronous) - could be run in either modes, but requires different GALs
  • optional 68881 or 68882 - runs at the same speed as the CPU
    memory
  • optional 32 kB level 2 cache
  • four EPROM sockets for 32 bit Kickstart access
  • memory expansion is possible for the 030 version only
    notes
  • the 020 and 030 versions have slightly different layout
  • five GALs - there are different GAL sets for each configuration (computer type, CPU type, CPU mode)
  • plugs into the 68000's socket
  • optional 68000 fallback mode - the 68000 can be installed onto the PAK with an additional GAL

    integrated voice mail and fax system
  • Yamaha YTM401 voice-fax chip
  • sending and receiving of faxes at 2400-9600 bps
  • auto fax detection
  • audio record and play back at 9600 Hz, 8 bit
  • two RCA connectors: line in for digitizing, line out for audio monitoring of incoming calls
  • two RJ11 telephone jacks: one to the phone line, the other to a local telephone
  • audio can be recorded and played back through the local telephone too
  • an attached fax machine can be used as scanner
  • voice compression feature
  • record and play back of voice and fax messages remotely
  • schedule sending faxes
  • multiple PhonePaks can be installed for multiple phone lines
  • multiple PhonePaks can share mail boxes
  • in order to use the PhonePak in an A3000 or A4000, a Zorro II RAM expansion has to be added in another slot because these machines have problems with Zorro II DMA to Chip RAM
