Subject: [stella] 6502 guru's... From: Mark De Smet <de-smet@xxxxxxxxxxxxxxx> Date: Wed, 12 Jul 2000 21:44:59 -0500 (CDT) |
I was looking at some datasheets for the more recent versions of the 6502, and noticed a few neumonics I hadn't seen before. BBR0-7 and BBS0-7. They are branch on bit 0(-7) reset, or bit 0(-7) set. The datasheet makes note of the instructions that are new from the original 6502, but these are not marked as such.(they are opcodes 0F-FF) Does anyone know if these are supported in the 6507(original 6502)? Does anyone have the datasheet for the original 6502? Mark -- Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://www.biglist.com/lists/stella/
