If you can get both yes.
I have a 2GB CF in a PCMCIA Adapter which I copied the System 7.6.1 on my 5300ce as a back up drive, and tried it on my 1400/133 & 166. They both booted the CF card. Then I took it to the next level and used a PCMCIA Flash Memory card (512MB), though I had to remove a lot of extensions and control panels to make System 7.6.1 (same one on my 5300ce) fit in the card, it did boot on both 1400s. Both 1400 has OS 8.0 on their Hard Drives but I'm thinking of formatting the drives for System 7.6.1
And yes, when the CF with the 5300ce System 7.6.1 is moved to the 1400's IDE with a CF to IDE Adapter, it boots there too! Nice and quiet I will add!
