I'm (slowly) building a 32016 design kit. I'd like to support someone interested in a PC board, for plugging in a PC (PC^2 ?). The features I'd like include using the full chipset (including MMU), using SIMMs with 256k or 1Mb chips (allow 512KB to 8MB RAM), and letting the RAM be configured as EMS ram that the PC can use when the 32K isn't using it. I'm a software type, and would be glad to spec the required hardware (4 9-bit latches, and some decoding) and write the software. I have designed hardware in the past (and actually seen it shipped), and have written several EMS 3.2 drivers. I think that letting the RAM be dual-purpose will help justify PC owners buying a lot of it. I can use it for RAM disks, etc in my PC software, or use it for the 32K system, or any mix. I'd be happy to work on the PC software (such as communications, drivers, etc) as time permits. I have done similar work on other co-processor systems. Does this sound interesting to other 'small' users? Don Corbitt (Don_A_Corbitt@cup.portal.com) VP R&D, CrystalGraphics, Inc. Voice: 408 739 8133
