They are a great machine...i almost got a 3400/200 once...but i think everyone knows about that...."The One That Got Away".

Anyway, you can dual boot one with 7.6.1 and other newer versions of the Mac OS...i have my 1400 set up in such a way. Just remember to give System 7 a big enough partition, as it is unable to read HFS+ volumes.

Also, the original iMac had a special copy of OS 8.1, which was especially made for the iMac.
