Multicomp Z80 with b/w Graphics Extension

LOL]] All c-/asm-source and binary files are included. For assembling/recompiling you need the M80 Assembler and the MESCC C-Compiler system from Github. Instructions how to do both steps is described in 'xgraph.txt' included in the 'Multcomp-Z80_xgraph-*.tar.gz' package. I haven't checked whether the HiTech C-Compiler can do the job too.

Builder's Notes/Comments

For programming the RSX I used the package from Miguel I. Garcia Lopez as a example/guideline for building my own RSX and C-function files. You can find his original software on Github The Multicomp VHDL-Code incl. the CP/M software I've got from here in the forum. The PCB and the Mini-FPGA-Board can be found here in the forum wiki. One comment regarding the Mini-FPGA-Board: The Multicomp version using the Cyclone-2 chip can't be used with the graphic, because of not having sufficient internal block-RAM (mainly) and LE's.

The package has reached it's planned basic functionality now. The only thing still missing is something like a Reference-Manual, describing the C-functions and the RSX. That should be done next, but I can't say when that will be done, the upcoming spring forces me to focus on other things ]] VHDL and RSX-/C-code are well commented, that should fill the gap to some extent.

For those who own a multicomp-6809/6502 and wish to use my graphic-modification, I have incl. my last BASIC-Version of the graphic library I used to test the hardware in the Files-Section. It has all line and text functions at the level when I started to code the RSX. It is pretty usable and fast when compiled with the CB80 BASIC-Compiler. The code is in plain ASCII.
