Yes there was the Crytronics/PCSG ROM Module (attached photo). It can hold up to six (6) Option ROMs and it has a rechargeable battery pack. It attaches into the M100 leg holes and plugs into the Option ROM socket. The batterles plug into the power socket and the wall wort plugs into the ROM Module.
Switching between ROMs was/is done through a rotary switch on the right. Best if switched with the unit off. The active Option ROM in the M100 Menu only shows the last active ROM. So, you must enter and exit the available option before it changes. Say you're in the Super ROM using Lucid and want to send the spreadsheet over to your desktop PC. You'd save the file to RAM, exit Lucid and Super ROM to the M100 Menu, and shut off the M100. Then change the ROM Module rotary to Disk+ and turn on the M100. At the M100 Menu select SUPER (last active ROM) to enter Disk+. There you can send files to a desktop running Disk+ Desktop (PC, I/III/IV, CoCo). When you finish sending and exit Disk+ the M100 Menu will have DISK+ and not SUPER. Will need to do the whole switching bit to change back to SUPER. At the time, it didn't seem like much to do. to be sure it was less trouble than writing this reply, with picture, on my iPhone with a Palm Graffiti wannabe.
