I''m looking to assembly programming information and to purchase the following items for this system or the system including these items. Does anyone have a TV/monitor interface or any extra info about it? Does anyone have any extra information about (or have?) the EPROM expansion board that Tom Klein described on the main page here for the HHC? He said, "It was housed in a one-inch thicker tray and interfaced between the printer and compueter, adding about 1 inch to the length." And it had sockets for 8-64K EEPROMS. I am curious how the bankswitching was performed.

Several years ago, I managed to contact one of the developers of the systems software used in the Panasonic HHC. He had retired to an idyllic life to an island somewhere.
I had emailed him inquiring about the SNAP language, and he graciously responded. He wrote that SNAP was a custom forth executive ( similar to a runtime ) and that the applications were developed on Apple II computers.
For those unfamiliar with forth, the programs can be compiled to a list of memory addresses that point to library functions or data. The runtime is a program loop that reads the top address and calls the library function at the address. The called function may add, to or change the list. The net effect is execution speed close to a compiled program, with the compact program size similar to an interpreted program.
I suppose, if one was determined, they could extract a rom image, and byb comparing the application roms to the systems roms, and identify the entry points, and using this info and amodern forth environment write custome software.
