- 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.
