New VDP daughter board run more Colecovision games

New PCB arrived.

This board optimized using the VRAM and CPLD for less space.

And added sound chip.

Video automatic switcher applied.

Joystick support for the SG-1000 and the Colecovision.

Mode selection Switch SG-1000 /COLECOVISION

Unfortunately I did some mistake and fixed as below.

The Z80 board connector relocated to right side hence it would be as below.

CP/M Turbo7 Z80 card doesn't soldering a connector so, user can solder for their purpose.

In this case, I soldered pin connector male and female for joint.

But, after connect it both, it consume another slot space and may interfere.

Even move the connector to Right on VDP board.

It still consume some space but, some of small card may be usable.

I hoped the VDP option board in slot7 cause there is no other socket on right side so free of space.

If really don't like this combine, maybe can use short IDE40ping cable could be used.

Here are some more running game on COLECOVISION mode.

Here is a Joypad for game play or input device.

This VDP&Sound option board will work under CP/M hence,

It can be also used to make game or other program under CP/M.

Hope to make good fun software under Turbo pascal or Z80 ASM.

New Option board would be prepared some weeks later.

If you have any concerns, please let me know (quick09@gmail.com) .

Thanks a lot
