Message-ID: <999@houxs.UUCP> Date: 27 Sep 88 21:51:49 GMT Organization: AT&T Bell Labs, Holmdel, NJ Lines: 29 Not long ago, Chuq asked if a large screen (one with more pixels) could be put on a 512E if there was already a Dove 2Meg+SCSI board in it. My gut feeling is that there probably is no such beast, because the memory expansion boards want to clip onto the 68000 chip, and the monitor boards also want to clip directly onto the 68000 chip. So you have to choose one or the other. Not having seen any responses yet to his posting, I'd like to generalize on it a little. Are any large screens compatible with ANY 2Meg+SCSI expansions in a 512E???? Some 512E-compatible "accelerator" cards support extra memory, SCSI, and an add-on monitor (TSI's new one fits this description). However, you have to pay extra 'cause accelerator boards cost more than simple memory+SCSI boards. [Extra credit question for Mac hardware hackers] Would it be reasonably straightforward to build a simple (minimal/no active logic) interface card/cable that would clip onto the 68000 and would provide a place for a monitor card to attach AND a place for a memory+SCSI card to attach? Assuming the mechanical details could be worked out, are there other potential problems? For instance, would something like the Radius FPD put its screen RAM in the same address space as that used by a RAM expansion? Dave Wolverton att!houxs!daw
