8 bit CPU simulationWhen designing the HC680 minimalist processor, particular attention was paid to the historical processors in the following listing. Due to the deliberately very limited resources of the HC680 system, it was only possible to follow the instruction sets to a limited extent.  Motorola MC 68000 family https://archive.org/details/bitsavers_motorola68ogrammersReferenceManual1992_2394181 MOS Technology 6502, Zilog Z80, VEB Mikroelektronik U880 (some in German only)https://www.c64-wiki.de/wiki/%C3%9Cbersicht_6502-Assemblerbefehle http://www.myquest.nl/z80undocumented/z80cpu_um.pdf http://www.z1013.de/u880_befehle.html http://www.kc85.de/Service/Dokus/M027.pdf Intel 8080 https://archive.org/details/bitsavers_intel80859mblyLanguageProgrammingManualNov78_5034151 8008 http://8008.classiccmp.org/8008UM.pdf 4004 http://www.applelogic.org/files/4004Data.pdf ______ The current topicality of the external links cannot be guaranteed. |
