Wow, very interesting.

Out of curiosity, how does this cartridge interact with onboard MSX-Music?

Is it possible to have it on port 98 on the MSX1?
A candidate for the cases "halp, my VDP is fried".
When it is not fried enough, the manual should hint wich pins to shortcut to disactivate INT and RD on internal VDP? Smile

Currenty the MSX music emulation is not a part of the FPGA design. Hence, any external audio source is connected to the AUDIO IN on Procyon board. It will be digitized at 48KHz and mixed up into the SCC+PSG+PPI stream and distributed via analog outputs and SPDIF/TOSLINK. The same way Philips MSX Audio/Toshiba/Yamaha SFG05 will be distributed in the same way. It requires an RCA mono or RCA stereo to 3.5mm jack cable

Did I read a 75Mhz Z80? Now that is a kick in the performance levels. Finally some decent multitasking capabilities.
Count me in Smile

75MHz Z80 is the CPU speed in the Canis Minor card, which will be connected to Procyon:
Canis Minor + Procyon => MSX

The idea is to have a fast processor emulation card + fast graphics emulation card.

Canis Minor will be of the same complexity as Procyon and no BGAs. Two together will form the hand held computer with the LCD panel.

I could fit Z80 in Procyon, but I've decided not doing it, since anyway, I need a slot adapter board. Procyon can adapt Z80, but 68000 wouldn't fit. Hence, for Genesis, Amiga and others, dual board architecture will fit.

Certainly.
However, currently if the card sits on 0x98 - 0x9B , these ports are write only and no interrupts related to VDP are generated to avoid "heeeeelp, I've fried my VDP" Wink

@ALL,

Thank you very much for all the feeback and board requests. When the board, time schedule and the pricing are finalized I'll publish the pre-order list. I'll inform you when it will happen.

Thank you again!

This card also can work in the stand alone mode emulating 8-16 bit home computers and simple game consoles

Hi Maxis,
Is the emulation in this card supports all 8-16 bit home computers and consoles?

If yes.... Then Amiga 500, NES, SNES, Sega Mega Drive, NEO GEO ... Will be run by MSX.

Please provide a list of the computers and consoles that fully supported by this card.

Regards,

Sniper

Amiga with the OCS graphics donesn't fit into Procyon, no way.

Sega Mega Drive - neither (same problem).

However, Sega Master System and NES will do fit into Procyon alone, Amstrad Schneider, BBC Micro, Apple ][, ZX Spectrum, Commodore 64, Atari XE or XL series will do too.

NEOGEO, Amiga 16 bit (500/1000/2000/600), Atari ST, Genesis and X68000 (but requires OPN FM support) will not fit into a single Procyon. However, these machines will fit into Canis Minor + Procyon two card setup.
This is about the HW support. FPGA designs yet have to be ported or developed (2K man hours per machine)...
Imagine, NEOGEO for example, took a team of 30 HW designers about 3 years to develop. We don't start from the scratch (MAME emulator) but still it is one of the most complex 16 bit arcades.

It is not MSX, which can run Sega Mega Drive. It's Procyon, which can emulate correctly MSX and many others.
