I have four Rev.2 Atari 520ST systems (*very* early revisions) and I want to upgrade them with the TOS ROM set. The instructions for upgrading don't seem to work on the boards I've got - they talk about links on the ROM sockets, and I don't have any, nor do I have the MaskROM pads beside the ROMs. I tried upgrading one board (using Atari's instructions) and got a dead 520ST; taking the mods out again left me with a still-dead 520ST. Sigh. Also - I'm running one machine with two SSDD 3.5" drives. When I replace the second drive with a DSDD drive, the machine can't see it. The DSDD drive by itself works OK. Anybody upgraded Rev.2 boards *without* the ROM socket pin 27/28 links? Or daisy chained disks? Help??
