I picked up a Mac 512 the other day, for what I thought was a good price, with keyboard, mouse, and a coupla external 400k drives. When I got it home, and tried it out, all I got on the screen was vertical black and white bars. I opened up the case to peek around inside of it, and saw some kinda retrofit memory boards on it. One of the boards was an extra memory board that fitted itself over the onboard memory, and the other board was one that fitted itself over the ROM lo. This one had the ROM lo, and another ROM chip on it. Anyways. Can anyone lend me a hand fixing this thing? Id like to not spend money on it, considering its age, etc. But I would like to get it working. I was wondering if anyone has run into a similar problem, and knew how to fix it. Thanx in advance.

I own such a machine except that it has the /e roms and 800k drives instead. Possibly the same memory extension board -- mine's from Dove, and also a Dove SCSI attached. I get "sad mac"s every few months, especially if I move the machine, and the remedy is to take it apart, take out the logic board, with all the dove boards attched, and shove everything in tightly again (make sure you discharge static first, of course) and then put everything back together and it'd all work again for another month. I guess those 3rd party boards since they are hacks to get it to have more memory anyway can get loose after a while and cause a memory error or something. -- Ian Chai | "God loves you just the way you are, but Internet: chai@cs.ukans.edu | He loves you too much to let you stay that Bitnet: 2fntnougat@ukanvax | way." - Harry Poindexter
