Original GameBoy: IPS Mod Horizontal Lines

The IPS display mod for the original GameBoy from a couple of weeks ago already developed a fault. bright horizontal lines run through the display, and it seems a full replacement of the LCD panel is needed. It seems these mods are a bit fragile. Also the display lens is a bit crooked and needs fixing. So off to another round of DMG modding!

Original GameBoy IPS Mod

A friend gave me two GameBoys, one of which he wanted back after the repair. The other one was dead and I could keep it. So after a quick testing I determined that only the display board was broken due to quite severe battery damage. While maybe salvageable I decided to use a drop in IPS LCD replacement board, as the original DMG screen is pretty abysmal anyway. This mod is relatively easy to install, and requires no soldering!

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.
