Processor: 020@7.2Mhz
FPU: 68881 or 68882 @ up to 33Mhz (PGA)
MMU: No
Ram Type: None. Does not support the addition of memory.

A small board measuring approximately 3.5" x 2.75" which plugs into the CPU socket. Due this card using an underclocked 020 and not supporting additional fast ram, it only achieves about a 10% speed increase of the standard 68000. The FPU can be clocked synchronously in which case it's about 7.2Mhz or an oscillator can be installed to support an FPU at up to 33Mhz. The card apparently does not work without an FPU installed.

Jumpers

For synchronous FPU clock (~7Mhz) short pins E2 and E3
For asynchronous FPU clock (uses oscillator) short pins E1 and E2

Comment of VRGDxDSOB6:
Except for the odd purchase at Readings or Borders, I haven’t bought a book from a shopping centre bookstore like A&R, Dymocks or Collins for I don’t know how long. Their selection and choice is truly dismal, particularly in the genres I enjoy (comparative religion; organic ho-guekeepins; and SF – I’m eclectic!)I would say I buy a good 95% of my books from the internet. Amazon Traders and Abebooks are pretty much my regular stomping ground, although I’ve been brave enough to try a few Lulu books.
