MSX USB

Have one Kingston and one Sandisk USB stick and both work fine. Haven't tried an external disk. Will try this as well.

@S0urcerer, I'll contact you by e-mail to work on the project.

In my schematic I had a current limiting resistor for the USB power. After removing that, a lot more USB sticks are recognized. Cannot boot DOS yet but 'call usbfiles' give the files on FAT32.

Cartridge PCB and firmware completed.

Over the past couple of weeks I managed to get my MSXUSB hardware working. It is based on an Altera 7000 series CPLD and combines both the CH376 IO selection and SCC compatible 512Kb Flash Rom.

Excellent reason to learn Verilog and refresh my PCB design skills. Schematics, PCB, Verilog code can be found, as usual on my Github.

PS. I intend to create 4 additional MSX USB cartridges based on this prototype design. So that more people can join in creating MSB USB software or get even more devices supported. It's a prototype so not yet consumer friendly. If you are up to it and are interested, check my profile, and send me an email.

@popolon_ i guess that ROM is independent, i used latest code (recompiled for RookieDrive) together with external FlashROM and RD NX and it worked as it should

Cool That would be great asset as more users can try it
