Definitely not (i'm not OP) but the components on those circuit boards look far more robust than modern surface mounted caps and resistors. Plus leaded solder flows a lot easier, in my limited experience.

For full functionality, the system also requires a 4 KiB SRAM card ($139) and some form of storage controller; at a minimum this would be the H10 paper tape punch/reader or the H8-5 Serial I/O card ($110) which controls a cassette tape, using a 1200-baud variant of the Kansas City standard format.

Memory prices have really gone down lately huh

Compared to the Xbox 360 I was just working on? It might as well be a plain rock. If you try microsoldering with a straight-to-mains soldering iron, you're going to end up with a scorched board at best and an electrical fire at worst.
