Re: MFX mass-storage add-on
It's been a little quiet, so here's a bit of an update for you . . . .
I don't have a few parts that I need to fully test the first version of the PCB, but here you can see probably the largest (by area) memory only upgrade board ever installed in an MTX !

Re: MFX mass-storage add-on
looking good, am looking forward to the finished version
Re: MFX mass-storage add-on
Thanks Jim,
IT'S ALIVE !
Well, at least the memory expansion part is

Re: MFX mass-storage add-on
So much better looking than the prototype too!
Re: MFX mass-storage add-on
The "smarts" all come from that prototype though

Down near the bottom of the page there's an explanation and an example.
Basically make the crisp clean VGA image look more like a noisy RF signal on a TV.

To add to Dave's photo of a part completed board, this is what it looks like in all its completed glory!
The FPGA can be personalised, so my board carries serial number MA00 as shown on the CPM boot screen. Dave's would show DS01 instead .
The Wiznet module in the photo is tested and working as both FTP client and web server. Transferring new software for testing is now a breeze!
There are other things that could possibly be added, but basically it's done, it's meeting all of the design goals.
3D printed end plate is still to be done. That won't be until any niggles arising from testing are sorted and the risers are removed alowing the case to close.
The FPGA board is on risers to allow easy access to the programming header, so I'm running externally powered. In it's proper position there is a power supply from the board and the external supply becomes optional. That would be done using the connector on the end.The FPGA can be personalised, so my board carries serial number MA00 as shown on the CPM boot screen. Dave's would show DS01 instead .
