    Mac Plus analog board replacement

    I just had a fairly catastrophic failure of my Mac Plus analog board. A few components are seriously charred, and though I haven't removed the board yet to check over thoroughly (it's too late at night to start doing this properly), I expect there will be too much damage for anything other than...

    64K ROMs and 800K floppy

    Here's a slightly strange one. My 128K mac had been upgraded to 128K ROMs and internal 800K drive. Since my Plus covers this space well and I wanted a representative machine with the 64K ROMs I downgraded it, but kept the 800K drive (because I don't have a 400K drive and it appears to work...
