Great achievement HRA! Just out of curiosity, how big the Terasic DE0CV FPGA is compared to the 1ChipMSX one?

It seems it is not using all 49K LEs, as Victor Trucco has made a port of this De0 firmware to SM-X, and SM-X has about 20K LEs... Tongue

So technically speaking, a port to Mist board (25 KLEs) is posible Smile , in fact the SM-X it's a Unamiga board, that it's smaller tan Mist and both of them share the same MSX core.

Currently, the OCM改 consumes only 40% of DE0-CV. Wink

Good afternoon hra!, I was wondering if you could buy me a DEOCM and send it to Spain, since I am talking to a couple of hard manufacturers and they are very interested in it.
thank you.

@HRA! Are you using the EPCS to put the MSX BIOS in there and boot from it?
It seems that either in newer Quartus versions or newer FPGAs EPCS access in only available in parallel form.

(I am (trying) to build a FPGA board to run OCM on, it's challenging Wink )

I'm sorry.
I can't broker the purchase.
