Another thing to watch out for is that the A3000 has to have the daughter board plugged in before it will boot up. Now the A4000 will boot up without the motherboard. Good Luck on your endeavor, I have been working on my A3000 for the last 5 years, bought another one 4 years ago and it quit working this year. (big sigh), but at least my old A4000 still works but it is starting to start up with a yellow screen (oh no). My other A4000 worked about 5 minutes after I bought it, back in 95, but the good news is my old A500 is now fixed and working it was the Gary Chip gone bad. Now another piece of good news is that my CD32 still works, now only if I can find my SX-1. See what moving does to you. Still trying to sort out my disk collection of IBM and Amiga disks, the moving company packed them up all in one box, yes they just dumped them in, I guess the disk god wanted to have some fun with me. Found my new 5.25 disks for my C64 but only the blank ones, have yet to find the program disks, I think they are gone just like my A1000, isn't moving fun. My old A7nX PC computer arrived in 5 different parts as well as my old MSDOS machine, now if I can only locate the case. Got the MSDOS machine (motherboard) video card, floppy drives, memory and cdrom, don't know if the CDROM still works, but the basic stuff still works. Never put your wife in charge of moving while you are working your new job, when she moved my computer room it has been 10 years and I am still sorting stuff out and rebuilding. Good Luck on you A3000 mine used to work, but now what can I say. If the guy in Panama City Florida that grabbed my A1000 still has it can you please return it. It is in a Gray xerox typing machine case, with an Aspirit board, 68010 accelerator, Supra HD Scsi card, 5 hard drives, with seperate power supplies so that I can turn each one on or off, a supra modem, and 3 disk drives. See what happens when you tell your wife that all the computers in the garage can be thrown out, but then you forgot about your build up A1000 and C64, oh yeah forgot about my C128 desk model. But as luck will have it, I still have another 4 big boxes to go through but they will probably be cabling and wire. 10 years and still going through boxes and sorting. You should of seen my Otrana suitcase lugable computer. Can you say pancake. but the keyboard broke away from the case as it was flattened. Never move again, if I do I will sell every computer that works before I leave.
