My Lisa has H/88 ROMs (I believe) and no screen mods. You can tell if it *doesn't* have screen mods by the fact that the Mac OS looks very "tall" on the screen.

I rescued it from running Mac System 4.2 (I think) and its been running Lisa OS 3.1 with all 7 apps for quite some time from the 10MB internal Widget. Fitting a 400k Mac drive is the cleanest way to got but look at the grey cables, often they are torn or puntured from mishandling (they are fragile) and you may have a wire snapped on one of them.

You won't be able to install the Lisa OS unless you have "virgin" or "deserialized" (or the original!) disks.
