Help identifying ROM chips

[erichelgeson]

Hi all,

I found a set of ROM chips - I think they came from a Mac Plus - I vaguely remember (I was probably 5-6 years old) my Dad pulling some ROM chips out and doing some sort of upgrade to our Plus. I know he did upgrade to 2.5mb of RAM, not sure what else. I've also included a photo of the chips currently in the Plus.

Quick search on these part numbers didn't turn up much.

I recently picked up a 512k, was wondering if they are "Plus" roms, if I could upgrade it potentially.

Not genuine Rom for sure in my opinion.

Apple Roms have the Apple name on them and 34xxxx  code as well.
