Once fitted with memory, the card provides a very slow, basic PCenvironment. In the photo opposite, you can see that the card comprises two circuit boards but it only uses one NuBus slot. A bulky 78 pin connector at the back of thecard is intended for external expansion I have found references toan expansion box but more information on this is welcome. There are two expansion slots (one 8 bit and 16 bit) forstandard PC ISA cards. There are four 30 pin SIMM slots that I havetested with 256Kb, 1MB and 4MB SIMMs the 386SX processor is limitedto 16MB of extended memory, so there is no point in testing largerSIMMs. My card has a 386SX processor running at 16MHz and a separatemaths co-processor.

Someadditional notes obtained from the documentation can be found on my Update page. October 2003 Update: Thanks to John S, I've now obtained anew in box Orange386 card and a new in box peripheral kit. Unfortunately, I don't havethe oringinal documentation for the card and software so everythinghere has been found on the internet or has been obtained by my ownexperimentation. I have used it formy testing in a Mac II fitted with upgraded ROMs and a 1.44MBSuperdrive capable of reading PC disks. It is afull length NuBus card designed to provide an Intel 386 PC(DOS/Windows environment) for the Mac II series. The Orange386 is the third generation PC card for the Mac. JohnRuschmeyer (this link broken when last checked) provides a moredetailed description of the early PC products. When AST quit the Macmarket, development of their cards was passed on to Orange Micro,better known previously for their Apple II expansion boards. The first product was the short lived Dayna MacCharlie for the original 128K and512K compact Macs and this was followed by 806 processorcards for the Mac SE and Mac II from AST.
