My firend picked up a lot of old Macs that were sitting in a basement for last 10 years. Mostly from the 1991-98 era, including two Power Macs 6100.

I fired them up... and nothing! Then I realised that the ROM chips are missing in both, such a bummer.

Is there a way of getting them? On eBay, there are none. Can I use for example, a 7100 or 8100 ROM in a 6100?

Perhaps is there someone that makes new SIMM modules with ROM chips?
