Daystar DiskRunner SCSI card

Posted by: beachycove on 2013-02-23 16:02:23 I have one of these cards, and popped it into a IIci last night. I fired it up with 4x4MB RAM, for a 16MB cache. 🙂 It seems to be working fine, though the IIci takes a little while longer to start up and I frankly don't see a lot of difference in performance. I also have a RasterOps 8/24Xli video card in the IIci, which is an interesting video card with another 4 RAM slots, able to give me a 5MB RAM disk and a 5MB GWorlds video RAM buffer. I want to try to do some benchmarking in the next couple of weeks. However.... What I am wondering about for now is the socketed 68000 processor on the Diskrunner card, which is meant to take the load off of the main CPU. Have a look at it on the attached photo: it looks very like the arrangement for a socketed 68882. Now, the question of the moment is this: Do 68030 processors exist that could be popped into that socket (e.g., could I cut one off a dead board for this purpose?), and what would most likely happen if I were to replace the 68000 with such a 68030? Would anything fry or might it just work?

Posted by: Macdrone on 2013-02-23 21:12:07 68000 square is set up like an FPU (edge connections) the 68030 is a socket with pins. Two different animals. Would be a neat idea otherwise. I think the code is different also but not as sure about that. Physical diffrences are easier for my failing mind lol.
