• CF card reader to replace HDD
• Install FPU
• Install Fast TOS 4.04
• Disable wait states

Just checking to make sure it's working as expected to begin with

There are two types of NVRAM on Falcon boards, the Motorola is the most difficult to remove as its legs aren't visible on the top side, so all the work needs to be done from the bottom. The ground plane is very strong so I needed to use my hot air gun while protecting the area with kapton tape

A quick clean up with solder wick

Socket installed

NVRAM installed

Fast TOS 4.04 installed so we can later disable the motherboards wait states

Clock patch installation

100k resistor added to clock patch on SDMA line

Re-capping the PSU
