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.

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

no problem, we'll try to reproduce it with the caro´s schemes.
Anyway, thanks.

@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 )

OCM Kai checks whether the BIOS image exists on the SD card first.
If it exists, it loads the BIOS on the SD card.
If it does not exist, load BIOS from EPCS.

The BIOS image is the format peculiar to OCM-Kai.
It is not compatible with KdL's OCM-PLD v3.8.
The tool 'BIOS image maker' to make BIOS image file is attached to OCM Kai.

HRA!, I have a DEOCM. Is there a place where a firmware for it can be downloaded?

Okay, are you saying there is interest in producing DEOCM in Spain? Will it be distributed within Europe?

I am interested in a DE0CM as well. I checked the few mentioned URLs but it seems it is not available.
It should be possible to build one from scratch if really needed.

Currently busy trying to get HRA!s latest version running on my homebuild board with a of the shelf Cyclone V breakout board. So far I am only getting a black screen, with a custom IPL a do get text on the screen so the most important components are working.
As a backup/test platform I have a Terasec DE0-CV on order.

I'm trying to convince a manufacturer in Spain to reproduce them, maybe if there is a print run to launch, it will be easier to convince them.

Please click [DOWNLOAD] (2020年09月02日).
If you prepare the BIOS of FS-A1GT, it will start as turboR. However, it is t80core and slower than R800.
Create a BIOS image with BiosImageMaker and place it on the SD card.

DEOCM is a clone of caro's DE0 subboard.

It appears to still be in stock, but it's not clear if they are accepting purchases from overseas.
