VYMS - video / audio / RS-232 cartridge project for Comodore

Hi!

I'm long time watching progress of VYMS cartridge for Commodore 128, Commodore 64 and Commodore VIC20 - video and audio extension with RS-232 port and 192K Video RAM

What it is:

Cartridge uses Yamaha V9958 VDP videochip (used in MSX2) - with higher resolution, more colors and more sprites than VIC-II or VIC-IIe has, VDC has still higher resolution and TED color count is much more lower.

Llook at features:

Video RAM: 128 KB + 64 KB of expanded VRAM
Text modes: 80 x 24 and 32 x 24
Resolution: 512 x 212 (4 or 16 colors out of 512) and 256 x 212 (16, 256, 12499 or 19268 colors)
Sprites: 32, 16 colors, max 8 per horizontal line
Hardware acceleration for copy, line, fill, etc.
Interlacing to double vertical resolution
Horizontal and vertical scroll registers

VideoRAM used in VYMS cartridge offers 192K RAM, where is not comparagble even with our VDC

Cartridge uses also Yamaha YM2413 sound chip which offers 9 voices, 15 instrumentsThis is used also in MSX2 computer and was used also in music keyboards.

And there is also RS-232 serial port provided by 6551 ACIA and MAX-232 chips

Here's Steve Gray's project link

Why this post? Simply - development hangs still 2 years and I contacted Steve if will be VYMS finished. His words were "when I will have free time"...

I want by posting this thread to speed-up development and make Steve aware that we are waiting.

So, imagine - C128 with 3 displays, colorful, more sprites, add audio and RS-232 offers many ways to enhance system.

I hope we can talk about and speed-up development.

Agree anyone of you?
