V01b Mounting Bracket for MKS-70 VFD Module

V01b mounting bracket for Guy Wilkinson's VFD module for the MKS-70

After fitting a couple of Guy Wilkinson's VFD modules and realising that the controller PCB needs to be mounted to the rear of the MKS-70 front panel by drilling holes and using hex-spacers, I figured on trying to re-purpose my old V01 bracket. By adding three more holes, the V01b mounting bracket for the MKS-70 VFD module was suddenly born! 🙂

Here's my original V01 which removed the necessity to drill holes into the MKS-70 voice-boards, so as to mount Fred Vecoven's original PWM daughter-boards.

When I was installing a lot of Fred Vecoven's original PWM kits, I designed a bracket to make things easier. The V01 could only be fitted to MKS-70s that had Guy Wilkinson's P0004 power supply as it occupied the space previously taken up by the transformer. My original V01 however, removed the necessity to drill holes into the voice-boards to mount Fred's PWM daughter-boards.

Fred Vecoven then released his fabulous digital PWM upgrade which easily mounts to the MKS-70 voice-boards in place of the original MKS-70 counter chips. My V01 wasn't necessary anymore.

Guy Wilkinson's VFD module for the Super-JX is amazingly popular and rightfully so. Retaining a good degree of visual familiarity when compared to the original display, it's a great bit of tech and a super upgrade for these old machines.

The two components of Guy Wilkinson's GU-280 VFD kit for the Roland Super-JX; the display itself and the controller module.

The GU-280 comprises two components; the actual VFD (display) and the controller-board. The installation requires holes to be drilled into the MKS-70 display-board (to mount the VFD) and according to Guy's installation instructions, the front-chassis, facilitating the mounting of the controller-board to the rear of the front-chassis. While the former can't be avoided, the latter isn't exactly a prospect that everyone will relish. Using my V01b however, means that at least you won't have to drill holes into your MKS-70 metalwork!

Just like my original V01 bracket, the V01b still mounts in the space originally occupied by the transformer, using the M4 transformer mounting studs. This means that you'll need Guy Wilkinson's P0004 installed to use my V01b. Incidentally, Fred Vecoven's digital PWM daughter-board for the top voice-board can be seen in the top right.

IMPORTANT: I know I've already mentioned this but I feel I need to be quite clear that the V01b bracket occupies the space taken up by the MKS-70 transformer. Hence, it can ONLY be used if you have a P0004 power supply installed.

Note that the cables that Guy supplies with his GU-280 to connect the display part of the kit to the controller-board, reach just fine, when using the V01b.

When mounting the controller-board to the back of the front-chassis, only the top two screw points on the PCB can be used, as the front-panel ribbon cable running along the back of the front-chassis, prevents drilling of holes lower down. With the V01b, all four screw points are utilised, making for a more secure fixing. The VFD controller-board isn't going anywhere!

By the way, if you don't know about this, then you're missing out! Hey, you can read all about Guy Wilkinson's GU-280 VFD module for the Super-JX here.

If customers ask for it, I mount my Live-Forever battery upgrade under the V01b bracket. Convenient, eh?

My V01b mounting bracket for the MKS-70 VFD module will be available in my on-line store soon. I just need to get a few V01s drilled out! Don't hesitate to contact me if you're interested, though.
