Spectrum finishing touches (part 4)

With both Spectrum's working I decided on a few upgrades before calling it a day.  Both of the cover plates are beyond fixing so I decided to buy replacements.   The keyboard membrane on the Issue 4 also decided to give-up during the final stages and needed replacing.  Both of these were easy to fit and only took a few minutes.

I decided to upgrade both with switched power regulators.  These are much more efficient and remove the need for the heat-sink.  Spectrum's are well known for getting warm so anything you can do to reduce this will help future-proofing. 

 

With that done I declared them both finished, don't they look good :)
