Works for both 16 and 32 bit MCA machines.Can be configured for 2-8 MB, all autoconfigured, no switches. Very good board,we use them in our Novell 386 servers here at BACL, has their own LIM4.0 driver,and several specialized circuits for ease in operation and access (such as the ASIC - application-specific integrated circuit...) Just thought you might like to know... and the proces are cheap...for instance, for quantities of 1-4, the price scale goes like this. 0K 299 2MB 498 4MB 698 6MB 898 8MB 998 For larger quantities the price goes down a great deal....
