| Machine | Electrically works | Bootable ROMs | Max Addressable Space | Notes |
|---|---|---|---|---|
| II | YES | 8MB | Most II's ship with four DIP ROMs although have solder pads for a SIMM socket. A SIMM can be installed if the DIP sockets are removed and a SIMM socket is installed. | |
| IIx | YES | IIx, SE/30, IIsi, Q700 | 8MB | |
| IIfx | YES | IIfx, IIsi | 8MB | |
| SE/30 | YES | SE/30, IIx, IIsi | 8MB | |
| IIci | YES | IIci, IIsi, Q700, C610/650 | 8MB | |
| IIsi | YES | IIsi, Q700, C610/650, Q650 | 8MB | |
| IIvi/IIvx/P600 | YES | 1MB | These machines are a bit of an offshoot from the ROM perspective, and few, if any later ROMs can boot these machines. | |
| ColorClassic | NO | The ColorClassic has solder pads for a ROM SIMM socket, but when I tried to install a socket and a ROM SIMM, the machine would not boot. Perhaps more experimentation is in order. | ||
| Q700 | YES | Q700, Q650 | 1MB | |
| Q900 | YES | 1MB | ||
| C610/650 | YES | 1MB | (1) | |
| Q650 | YES | 1MB | (1) | |
| Q800 | YES | 1MB | (1) | |
| Q605 | YES | 1MB | (1) | |
| Q630 | YES | Q630 | 1MB | This is another case of the machine being off on a branch and no other ROMs working with it. |
| C/Q660av | NO | |||
| Q840av | NO |
Notes:
(1): Most of these machines do not have a SIMM socket installed from the factory, but have solder pads where a SIMM socket can be installed. A few machines are known to have shipped with SIMM sockets (and possibly their own SIMMs), but this is much more unusual.
