Description

There are probably a bunch of bugs. Not all opcodes have been tested. The DEM- and DEM+ code is based on the algorithms described here: http://xl.cocolog-nifty.com/blog/2009/07/gmc-4-no-9829.html License: CC BY-SA 3.0 [https://creativecommons.org/licenses/by-sa/3.0] GMC-4 image by Kungfuman: https://commons.wikimedia.org/wiki/File:Gmc-4n.jpg

Instructions

This is an emulator for the machine code programming system of the 1983 Gakken FX-Micom R-165 / Radio Shack Science Fair Microcomputer Trainer / Gakken GMC-4 Microcomputer Trainer. Usage instructions are here: https://www.instructables.com/Radio-Shack-Microcomputer-Trainer-Emulator-in-Scra/ An assembler is here: https://arpruss.github.io/r165.html For programming instructions, see manuals for the hardware versions: https://otonanokagaku.net/english/manuals/pdf/vol24_microcomputer.pdf http://www.progettosnaps.net/manuals/pdf/fxmcr165.pdf You can enter code quickly by pressing the upload button and entering a hex sequence like "0f001f00". I recommend running in fast mode (shift-click the flag). The built-in sample programs are not included. Here is a useful summary of the opcodes: http://tsoj.manga.org/gakken/otona_gmc.html
