RE: Panasonic HHC ROM 'capules'
Got the ROM 'capsules' in, wound up with 7 of them. All are boring insurance stuff. Made a quick 3D model of one today for fun. Now at least I can investigate the ROM power on sequence.
A friend has made some FLASH based ROM boards for the Epson PX-8 which uses a similar power on/off scheme for the ROMs to save power. He found the following whitepaper which describes the time from power on until first read in detail. His ROM boards are working so far on the PX-8. https://www.renesas.com/us/en/document/a...-nor-flash |
