Many moons ago, I purchased a 128 Mac (Couldn't afford a 512). Two years later, I used MacDoctor to upgrade to a 512. Then I had a local computer store install the 128k ROM upgrade. Now I have received the Dove MacSnap 548S upgrade, 512KE -> 2MB. Because of the sockets installed by MacDoctor, my mother board is in the shop getting at least two of the RAM chips de-socketed and mounted directly to the board surface. The raised RAM chips prevent the Dove board from snapping into place. My questions: 1. If only the two offending chips are lowered, there is only a very small clearance between the bottom of the Dove board and the top of the remaining socketed RAM chips. Dove says that it won't be a problem. Any first hand experience out there?? 2. The local computer shop is concerned that my power supply may not be able to handle the increased load of the new Dove board for very long. I purchased my Mac in Sept. 1984. Any viewpoints? Is there a power supply upgrade? ( I will be added a SystemSaver fan/surge surpressor before I use the new board.) 3. With the 128K ROMs, 2MB RAM memory, SCSI port, and 2 800K disk drives, will I have the functional equivalent of a MacPlus? I know that I should be scraping the whole thing and buying a Plus or SE, but I haven't had any problems with my Mac in the past four years and can't seem to financially justify its complete replacement. Thanks in advance for any responses to my questions! -- Dataman ( ...!hplabs!csun!fedeva!dataman) `Peace on Earth' was all it said ...

You are now pretty close to being a Mac+ (I was what you are except that I started with a 512). I then bought a Rodime drive and used FastBack (their backup program that comes with their drive) to back it up. CRUNCH! FastBack ate the Rodime and the other SCSI drive online at the time. They were mostly brought back with SUM, but I was more than a little upset. Rodime said it was a compatabilty problem with FastBack and the Dove SCSI port, and then the dealer said that there was a compatability problem between Rodime drives (turns out that it is ANY drive with Rodime internals, like Jasmine to name another one) and Dove. Before my little mishap I used a Warp 9 Photon 20 and FastBack and had no problems. The only thing it could be was the Rodime, the Dove SCSI port and FastBack all at the same time. I would like to say, however, that everything was fine before the Rodime, so as long as you stay away from Rodime drives you should be pretty safe with your new "Mac+". I hope this keeps you out of any trouble/data loss. Mark Cookson
