Add MON4043.mem, Monitor 4.0C and 4.3 in a single file.
sector0.mem is the first sector off of the disk, for debugging. |

BIT and MCS files for Spartan 3E Starter Kit, using Monitor 4.0C Serial
Monitor for I/O instead of Flashwriter2. Use male DB9 Serial Port on Spartan
3E Starter Kit for console, 115200,7,S,1
at monitor prompt, 'G E80C' to boot CP/M. |

Changed I/O addressing so addresses are not shifted left by two bits.
Commented out DDR controller, and replaced with 8K of SRAM.
Replaced FLASH memory interface with 4K SRAM.
Added Vector HD/FD Disk Controller, using FLASH memory for storage.
This design can now boot Vector Graphic 56K CP/M 2.2. But be aware
that there is only 12K in the TPA, since the Spartan3E does not have
enough block RAM to make more.
This system is enough to test the Z80 core more thorougly. The
EXZ80ALL.COM program on the included disk image tests all documented
Z80 instructions. Some tests pass, some don't. This means there is
more work to be done on the wb_z80 core. |

Initial implementation of a Vector Graphic HD/FD Disk Controller
with Wishbone interface. See the PDF in /doc for more information
about this controller.
For now, the storage is implemented in FLASH memory, which is read-only
to the controller. Also, the controller does not check (CRC) the disk
sector data, like the original does. Instead, it inserts 00's where the
CRC goes, to simulate a correctly checked CRC.
I am able to boot CP/M 2.2 using this controller, with the vgboot.mcs image
programmed into FLASH. See the diskimage/ directory. |
