Since I have most of the parts lying about and have lots of experience with 680x0 series micros I am making my own 68030 board to plug into a Mac Plus. I am doing this mostly as a fun project but also so that I don't get those annoying "Illegal instruction" errors and can run virtual memory. I hnow I can get a commercial 68030 accelerator for <$400 but that takes all the fun out of it. I learned today that I can't run virtual memory on a Mac Plus because the ROMs don't have some essential toolbox routines in them. I am told that I may be able to use "Compact Virtual" from Connectrix which, I think, patches the system to allow VM to work properly. I called Connectrix and they want $99 plus shipping etc but can't guarantee that it will work with my home made board. I spoke with their technical support people and someone suggested that maybe I could collaborate with a friend who already has "Compact Virtual". Well it's a good idea but I don't know anyone like that. So maybe someone reading this has upgraded to a bigger and better Mac and has a copy they don't need any more that they can let me use or will sell me the rights, Whatever! If it works then I'll go back to Connectrix so that I can get support, upgrades, manuals and all those goodies. The whole point is that I am not sure if it will work. The 68030 swap will almost certainly work but the VM part has me worried. So if anyone can help me out please send me an email. Graham. heyes@dadev.cebaf.gov
