2015-08-29 20:57:49 +01:00

AtomBusMon.bmm

Implemented 6502 register access functionality with the embedded core

2015-06-16 11:57:32 +01:00

AtomBusMon.ucf

Updated AtomBusMon pinout to match 6502, would allow piggy-backing in principle

2015-06-20 22:36:10 +01:00

AtomBusMon.vhd

Updated reset output to avoid the use of a tristate signal in BusMonCore

2015-11-15 11:37:50 +00:00

AtomCpuMon.bmm

Refactor: 2nd stage

2015-10-31 14:29:14 +00:00

AtomCpuMon.ucf

Added a jumper enabled fakeTube register at 0xFEE0 with value 0xFE to work around a beeb issue with pullups, incremented version to 0.28

2015-11-15 11:50:06 +00:00

AtomFast6502.ucf

Refactored AtomFast6502 to use new MOS6502CpuMonCore - works in new Atom at 4MHz and with tube

2015-11-15 11:50:06 +00:00

AtomFast6502.vhd

Refactored AtomFast6502 to use new MOS6502CpuMonCore - works in new Atom at 4MHz and with tube

2015-11-15 11:50:06 +00:00

Blank.ucf

Added Blank design and T65-based 6502 design

2015-06-14 17:57:26 +01:00

Blank.vhd

Added Blank design and T65-based 6502 design

2015-06-14 17:57:26 +01:00

BusMonCore.vhd

Updated reset output to avoid the use of a tristate signal in BusMonCore

2015-11-15 11:37:50 +00:00

MC6809ECpuMon.bmm

Changed to 18K ROM/2K RAM, version now 0.60, bitfiles published for all three designs

2015-07-06 18:49:57 +01:00

MC6809ECpuMon.ucf

Added a jumper to select between 6809 and 6809E clocking; increased breakpoints to 8; version now 0.52

2015-07-04 16:51:08 +01:00

MC6809ECpuMon.vhd

Refactor: 1st stage

2015-10-31 13:45:09 +00:00
