Commodore 1700 REU 512KB Upgrade

In the most recent episode of Commodore History, a friend of the channel, Tony Schiffbauer, acquired a 128KB Commodore 1700 Ram Expansion Unit at VCF East in 2023. He visited the host’s house with the 1700 and some additional burly 41256 256K x 1 DRAM, requesting an upgrade to his new 1700 to 512KB. While it’s not something the host would typically make a video about, Tony suggested it, prompting the creation of this episode.
