Hardware: Microbotics MBX1230XA accelerator information

The Microbotics MBX1230XA, or Paravision M1230XA, is an 68030-powered accelerator board for the Amiga 1200 computer that connects to the Amiga 1200's internal "trapdoor" expansion port.

M1230XA with single oscillator, no FPU (caps not original)

It has one SIMM slot for up to 128MB of RAM (72pin SIMM, FPM, non-ECC, 40-100ns).

EDO RAM is not officially supported, it's not mentioned it the manual, but user reports indicate that some EDO SIMMs work, and some don't.

It has a socket for an optional 68882 FPU (PGA, up to 60Mhz) with a socket for an optional FPU oscillator (otherwise uses CPU clock speed, via jumper setting), and a battery backed up realtime clock.

The software supplied with the M1230XA contains an excellent setup utility that allows some tweaking, and an equally excellent RAM test tool with proper documentation.

Some SysInfo speed test results:

~7400 dhrystones @ 50Mhz / 60ns RAM / 4 cycles (recomm.)
~8300 dhrystones @ 50Mhz / 60ns RAM / 3 cycles (experim.)
~8400 dhrystones @ 50Mhz / 50ns RAM / 3 cycles (recomm.)


These accelerator boards are very well-made, but seem to be very rare nowadays, making it difficult to find information and support in case of problems. Below is a list of sources that should help answering your questions about the M1230XA and keeping it running.
