All I know is that often, old clones like that relied on ROMs pulled from donor Macs (ROMs couldn't be purchased individually or legally cloned) in an interesting arrangement: they'd sell you the Mac and the notebook, pull the ROMs and put them in the notebook, then repurchase the Mac as a parts machine and give you the functional notebook.

I had the original manual for mine and it didn't really mention anything about EEPROMs. The software that came with it really just controlled the display and that trackbar thing. It may have included a battery monitor program as well, or maybe a patch to use Apple's program. I've got it stashed away somewhere...

If I get bored in the future I'd like to dig it out and try to get it to work again. Maybe I'd try to put in a real 68030 and an FPU or see if an SE/30's ROM would work in it so that I can use more software on it.
