A project log for MSX COMPATIBLE BOARDS FOR RC2014

Create a series of boards designed for the RC2014 bus to achieve MSX/MSX2 compatiblity

Last couple of weeks, I have revisited the video board.

Version 1.4 of the video board arrived a couple of weeks ago - this board has a minor change in layout and silkscreen.  

The main change was to add a mounting point at the back of the board for a spacer to help prevent flexing and making physical contact with any adjacent boards.

All the boards I am designing for this project have this same rear mounting hole.

I have refocused on making sure this board works in a standard RC2014 configuration with RomWBW - and have been hacking some software - learning how to fully utilise the hardware acceleration features of the V9958.

I have decided that I would offer this board as a full kit on Tindie.  I have 4 kits built up and online at Tindie.  If there is demand - more will be made available - I seem to have collected quite a few spares!  The kits include everything needed (PCB, V9958, RAM, etc).

The latest version of the schematic and software can be found on the github project:

Fully Assembled for PAL output

Proudly installed in its RC2014 home
