Old SRAM PC-870 chain (top); new SRAM PC-870 chain (bottom).
Measuring from the center of one rivet to the rivet 23 away on a new chain is 12 inches (~30.48 cm). My chain was over 1/4 inch longer. Park Tool recommends replacing the chain when it is 1/16 inch too long.
Replacing the 8 speed cassette is a problem because of the dearth of parts, considering I need a ≥28 tooth lowest cog. I’ve found Miche 13-28 Campagnolo compatible cassettes on eBay in the UK and Italy, but then I start to wonder whether I should keep trying to support shifting components that were last produced in 1997.
I’ve also found on Branford Bike that a Campagnolo 9 speed hub could be used by dropping one sprocket and using a Wheels Manufacturing 8 speed spacer kit, but that spacer kit is also no longer available.

I dropped my MacBook Pro (Retina, 15-inch, Mid 2012) on it’s corner. It didn’t cause any internal damage – the computer worked normally – but the the lid (with the display) became misaligned.
The misalignment made the lower right corner of the display scrape against the base of the computer whenever the display was opened. I thought if I could loosen the screws that held the display, I could realign the display with the base of the computer.
I used iFixit’s MacBook Pro 15″ Unibody Mid 2012 Display Replacement (by Andrew Optimus Goldberg (and 5 other contributors) as a guide to remove the lower case and to get to the six 6mm T6 Torx screws holding the display (there are three in each corner).
1. Remove the lower case. (10 Phillips screws)
2. – Note: the links to the following two iFixit links are to illustrate the location of the screws – the screws shouldn’t be removed.
3. Close the lid and move the display so it properly aligned with the computer base (the part that has the keyboard).
4. Tighten the six 6mm T6 Torx screws
5. Reattach the lower case.
