I'm having problems getting my new AMAX II+ Plus to work. On start-up I get a "ROM Checksum Error" message. I've checked all the usual stuff,i.e.- bent pins, ROM insertion problems, etc. Do any of you think I have bad ROMs? Is there anyway other than in a MAC to check these babies?

David, The only thing you might check is the possibility the ROMs are in upside down. Be sure the notch is aligned with the one on the socket. Otherwise I cannot think of what the problem might be. It would be odd that the ROMs themselves would be bad.

David By any chance do you run a GVP 3001 board in your system? I have both the Amax II and AMax II+, the Amax II WOrks great But the Amax II+ Comes up with the ROM Checksum Error. If I take out my GVP 3001 or use the switch I installed that lets me disable the GVP Board to run in 68000 mode the Amax II+ WOrks fine. I have called ReadySoft and they claim to be working on a fix.

James, If it's of any consolation to you, there seems to be a variety of problems with the 3001 and Amax+. Mine wouldn't read mac disks. Readysoft was kind enough to replace my original and now it seems to work fine witht the 2.51 software. They are working hard to squash these problems and they were most helpful to me, so bear with them.

I have AMAX II+ on my Amiga 2500 and I had the same problem for awhile. Sometimes it would work, sometimes a checksum error. I just mashed all the chips in, pulled them out, put them back in, never did figure it out, but it works OK now. I would look for loose chips.

I forgot to mention, while the book says it doesn't matter which space the ROMS go in, after I switched them it worked fine. Try switching the ROMs.

David, Please describe your system. I have the A3001 board and can only get the AMaxII+ working upon cold (and I mean very cold) boot. I also must have fastrom disabled. My other problem stems from figuring out a way to get System 7 installed since it comes on hi-density disks. And, the System file is 900+K, too big for a double density. I also cannot reliably read Mac floppies from my internal drive. Good Luck with yours!
