This is just a different way to pay the Apple Tax.

Ok, Greg must be very patient and/or certifiable. I thought my buddy Andy was insane for desoldering the 2,000 bytes of RAM in 1983’s Nintendo Entertainment System. This seems orders of magnitude more scary.

Fun fact, if you take the raw data of this boingboing BBS post you are already close to a quarter of the way to the total RAM available in the NES.

My first thought was from when RAM was discrete chips, where depending on the system, you could upgrade via “piggybacking”, i.e., soldering new chips on top of the old ones, and bending pins to isolate the address lines.

The mad quest for ultimate thinness—that I don’t recall anybody ever asking for—ruined everything. The MacBook peaked with the mid 2012 MacBook Pro: upgradable memory, upgradable hard drive, swappable CDROM, lots of ports, and a great keyboard. The perfect laptop. Mine soldiers on with its RAM upgrade and swapped-in SSD drive as my iTunes and Photos storage center for my phone, and has only recently started feeling slow to use.

I have newer computers, but that will always be my favorite.
