@S0urcerer, about this new CPLD design. What chips are compatible with you design? as there seems to be different variants from that EPM7064, so is only EPM7064SLC44-10N working one? That seems to be obsolete chip now, at least based on digikey.
@S0urcerer, there are for example EPM7064SLC44 with 7NS and 10NS, so it must be 10NS version? And you cannot use newer chip, for example EPM7064AETI44 ?
@popolon_, no sorry not the newer one. The newer one runs on 3,3 v. And the MSX on 5V. You can of course use resistors on every line coming from/to cartridge. Better to use the old ones. 10ns is fast enough for our MSX.
MSXUSB with powered Hub. I posted two videos on Youtube.
One shows my setup with the MSXUSB cartridge an USB Hub and 3 connected devices.
The other one shows the MSX booting, finding the hub, scanning the devices and selecting the storage device to boot from.
I created a low-level USB storage driver that also works on a hub. Before MSXUSB could only boot if the USB stick was the only device connected to the MSX. Now this is solved and storage and other devices can work together.
Next on my list are:
Stabilizing the driver and make it rock solid.
Merge the Usb Storage branch into the main branch.
Make rev.2 of my PCB
Ready to add more drivers to MSXUSB family. :)
P.S. Keep any bug reports or improvements coming. I also have a RookieDrive build on GitHub.
