I'm happy, the project is still ongoing, I wrote this

Hello, Jose,

The hardware is 100% finished and debugged. I need a very small modification for the PCB to correct a DFU mode. Currently I'm working on the FW for the microcontroller.

Plan to get it all done for the next MSX show.

Thank you for your feedback and patience.

Kindest regards,

Maxim

I really do apologize for my dumb commentary! I wanted refer to the pirates flag and did not thought much further.
Great there are fantastic things to come!

Merry Xmas Everyone!

Just to confirm, the project is still alive and kicking Wink

As you have noticed, I had a lack of bandwidth for the last 4 months.

Now mainly working on the DFU (Device Firmware Upgrade) which is the uC firmware. This way I can upgrade FPGA without calling back the boards or asking the users to install the full Xilinx tool chain on their computer and buy the programmer.

I have completed a large chunk of the uC FW for the USB host support and now the board can support HID devices (keyboards and mice). Still have to add the Xilinx support for the keyboard emulation.
The second thing is 4 wire SDHC interface supported in the uC. But still I need to find a time to write the DISK I/O routine and add the Xilinx support for that.

Once the USB keyboard/mouse support function is complete, I'll post the new video. Same for the SD card partition manager and DFU.

As you can see, there are still quite a few things to be done. But I'm focused on finishing off this project.
Thank you.

P.S. I apologize for the slow down, now it's more difficult for me to find a significant amount of free time to continue at the same pace. So, I continue but much slower...

Short Procyon update:

I have finished the debugging of the HID USB support for MSX uC firmware and the FPGA hardware. It runs flawlessly. You can plug/unplug your PC/MAC wired/wireless keyboard any time to Procyon card. Once enumerated the keyboard can work either together with your built-in MSX keyboard or instead (in case of the absence of the original MSX keyboard).
I've tested this HW with the following machines:
- Yamaha YIS805/256;
- Yamaha YIS503II;
- Toshiba FS-TM1 (same architecture as Panasonic FS-A1F)
- Yamaha CX5MII (not YIS503II motherboard)
Yet to try out:
- Panasonic FS-A1ST

Now, if the wireless transceiver is supporting both mouse and the keyboard, then both will be enumerated by the onboard uC but only the keyboard reports will be passed through to the MSX HW. Also the USB keyboard is used to go through dialogues in the Procyon OSD menu at any time. The distinction between MSX/OSD is done by pressing and holding the MENU/WINDOWS button.

Currently analyzing the possibility to emulate the mouse in the same fashion.

Video is yet to come.

It seems that I'm older than internet generation Wink adjusting the dictionary I'll rephrase this "YOUTUBE video is yet to come" Wink

Hi Maxis,

I respect the work has been done in this project. However, in my opinion, this project lost a lot of interest because it is delayed more than expected.
You announced this project in January 2014, which means 4 years and even more. You are expert, and you know that technology changed and enhanced in a crazy way and faster than any field. If you release this hardware one year or maximum of 2 years after your announcement, then it would have huge success with no doubt.

Now. I mean ... today .... We can plug Raspberry Pi into MSX and play all emulators by MSX keyboard (I am doing this now) so, what is the difference between your hardware and Raspberry Pi, I am sure they are almost the same, even Raspberry Pi might be better as it offers more emulators and it is already tested with no bugs.

This is only a personal opinion and I already reserved one unit from you and I'll be waiting for it. I am sure you will sell all units you have, because it is related to "MSX" ... but if this hardware for different system, then I can tell you ... it will die with no doubt.

Finally, I wish you all the best in this project and future projects as well.

Regards,

Sniper

Dear Sniper,

I understand your frustration very well. I have put so far quite a lot of personal energy into it and it is also very innovative and complex (at least the method how the board spies on the MSX VDP). Hence, it takes quite a lot of time to debug.

Making a yet another MSX FPGA emulator is no brainer since the card doesn't have to "play a solo in an orchestra", which is the original MSX machine.

Also I have learned a lot from these pages about the forum members (potential clients) and the level of tolerance to the HW malfunctions and expectations from the purchased hardware.
Therefore I have dropped the release of the version 1.0 (still fully operational, which was demonstrated at Nijmegen in 2015) and switched to the more robust version 2.0 (new design, new PCB).
As you can see the HW is 100% finished and now I'm working on the firmware support. In order to avoid the complains I have to polish the whole system before the release, make it robust and easy to maintain without calling it back for the FW upgrades. Also I have counted the total number of the orders and till now it is still inferior to 50.
I.e. with such a number I can't order the batch assembly and reduce the price. And just for the automated assembly of 5 boards, 100 USD per board for 5 unit badge seems to be a very steep price for the moment (the board has around 250 passive components and 30 ICs). With ZERO profit margin the price of one unit for the batch of 5 units will be around 170 USD (including the cost of components, labor and postage, no plastic case). Including the case and the box - 200 USD. This is the tough reality. I'm working with a couple of assembly houses and parts brokers in TW and CN in order to reduce the cost.
