Upgrading the PET 3016 to 32KB RAM

A couple of years ago I got a PET 3016 from 1979. The machine comes stock with 16KB of RAM and back then we upgraded it using a RAM/ROM expansion, giving it 32KB of SRAM and BASIC V4 ROMs. However it never ran stable in this configuration. It turns out the SRAM was not playing nice with the system. So in this video we will use new old stock 8116 DRAM chips to upgrade the mainboard to its maximum and hopefully get a stable system.
