MV8-VGA Do-It-Yourself - The GR8-VGA UPGRADE!

I sold the mv8k that i did the upgrade to. I did my pinout using an actual MV8-VGA card. If you have problems, please post. I dont have my original unit to reference. But I will help as much as possible.
Just remember this is a try at your own risk upgrade!
Refer to pinouts.ru/ if you get confused. I suggest everyone get the mouse to work first! You only need to have mouse connected to switch back and forth.The vga does not have power running to it. I suggest once you get wiring right, SOLDER ALL CONNECTIONS! Here is the pinout:
Red wire is CN 1
1 - 4 (m)
2 - 6 (m)
3 - 2 (m)
4 - 5 (m)
5 - 1(m)
6 - 3 (m) *
7 - gnd white wire
8 - 15 (vga)
9 -13 (vga)
10 - 14 (vga)
11 gnd grey wire
12 - 1 (vga red) white wire
13 gnd grey wire
14 - 2 (vga green) white wire
15 gnd grey wire
16 - 3 (vga blue) white wire
* = splice with vga #12
(m) = mouse
Wire # 6 is mon id, but splice this with VGA #12, and mouse # 3. Take gnds # 7,11,and 13 and connect together with VGA #5 gnd. (As long as you have two of the grey gnds together it will be fine). On the vga pinout 5-10 are all ground, the wire you may use might have two gnds within it. After it is identified, use the second gnd, usually vga #10, and connect with wire 15(grey gnd).
*If it dont work connect
6(mv), 3(m),12(vga), 10(vga),15(mv).
On my board pin (wire) #6 is connected thru a ground that has resistance in path. I ran into a problem when i did my upgrade, and it was ground related. If memory serves me correct, this fixed it. I know that with this upgrade, the mouse uses all six pins, which is different from standard ps/2. And it seems that it needs to be grounded.
Shout out to NZClint1, but I was right behind you on this upgrade!
Finally someone HACKED the VGA, that Roland Corp. does not carry anymore! Good Luck and shout out to all beatmakers on KZbin!
Try this at your own risk, or have someone that is handy to attempt!
Just type in "GR8-VGA / MV8-VGA".

The pinout of the 16 pin connector inside the MV-8000 is: Pin 1 (RED) +5V Pin 2 Keyboard Clock Pin 3 Keyboard Data Pin 4 Mouse Clock Pin 5 Mouse Data Pin 6 VGA Mon SDA Pin 7 Board Detect / Ground Pin 8 VGA Mon SCL Pin 9 Horizontal Sync Pin 10 Vertical Sync Pin 11 Red Ground Pin 12 Red Pin 13 Green Ground Pin 14 Green Pin 15 Blue Ground Pin 16 Blue For the MV to detect the vga / mouse connections Mouse ground needs to be connected to Pin 7 Board detect / ground. Then also a 10K resistor needs connected from Pin 6 mon SDA to Pin 7 Board detect / ground. Then also 11,13 or 15 needs to be connected to Pin 7 Board detect / ground. If you connect this all up correctly you will get mouse and VGA functions BUT!! the drum grid will not display correctly, for some reason the boxes / gridlines are missing making the drum grid difficult to use.

[@303fixinpcs]

Did anyone ever figure out how to get the drum grid to display? The grid lines do not show up on LCD monitors which makes the drum grid editor very difficult to use.

[@JabaarDugan]

So I HAVE TO connect a mouse in order to see my workstation on screen???????

[@303fixinpcs]

If you try this vga mod, the mouse has to be attached or the MV will not enable VGA output. It will give a "Mouse Not Found!" error when you try to switch to VGA + Mouse mode.

[@blaackone32]

How did you find the pinouts for the ps2 attachment and the vga dongle?The colors are different.

[@rich4real469]

Can you show what wires go where please. I 've been scared to try this for about 2 years

[@marlontillery]

Where can I find The Pinout for the VGA for MV8000

[@303fixinpcs]

its in the roland service manual, this is avail at mv-nation.com

[@dabagman7]

can u do the 8 out

[@PadBoll]

Hey, how could I find the correct stuff to add the vga/mouse ?

[@eterriblebeats]

But how did u actually splice the cables? Can u show that?

[@303fixinpcs]

I hope nobody ever cuts / splices the wires! Use a 2.0mm to 2.54mm pitch changer and a 16 position 2.0mm header to make a breadboard compatible connector to the mv8000. This was you can use a 2er hole breadboard to solder everything together safely.

im in the middle of making a professional looking vga card, i will make an instructional video and post as a response
