It all depends on what you are looking for and how far down you want to walk the path of emulation.

  • Do you want to revive an old MSX computer and bring it to the 21st century? Buy a Carnivore2.
  • Are you looking for a new MSX2+ computer with all the 21st century possibilities? Put your old MSX1 back in storage and buy a SX1Mini+ or similar machine.
  • Do you just wanna play those old MSX games you remember? Use an emulator like openMSX on your PC. It's free.

I am stuck between the first and the second option. I don't like emulators.
I had the impression that the SX1Mini+ would need to use the MSX computer for input, no?

If you mean input as in typing, you connect a pc keyboard (ps/2 not usb).

Yeah, that's a bit of a bummer... Those keyboards are harder to find than USB keyboards and even then there are those who have USB signal over PS/2 (often those who come with a PS/2 USB converter).

No, it's hardware "emulation": A totally self-contained computer which doesn't need other parts, beside cables, power supply and a keyboard (which you can still find VERY easily as 2nd hand).
Its main advantage over software emulators is that it can use original cartridges/accessories and it's ready to go as soon as you switch it on.

And if you are "disgusted" by emulators then you can forget the Carnivore2 and pretty much any other (SD) add-on cartridge too, as they use the same principle (FPGA/CPLD) and all have quirks. In that case your only choice is original software.

I think that’s a bit too harsh, FPGA alone does not automatically mean emulation, it also performs glue logic to make the whole thing work in a compact cartridge.

I also prefer original machines and original chips over emulations, especially for more complex chips like video or sound chips. I would rather use a real YM2413 OPLL sound chip than the Carnivore2’s FPGA emulation of it. Not that it sounds bad or anything, but sometimes I want to do certain unusual things (like playing samples) that I can’t rely on emulations for, and the original is the reference.

However there are no qualms about the RAM and FlashROM memory implemented with FPGA glue logic, or the SD interface. And the sound chip emulations can come in handy when you don’t have the originals, or not enough slots free to plug them in.

Where did I use the word 'disgusted'??
I only stated my preference towards physical hardware.

I know Carnivore 2 is a popular option but it has its quirks and sidepaths. Megaflashrom SCC+ 512kb is still a valid option and readily available. As I own both I could list all pros and cons but maybe another time. If you really want the best possible user experience from the original hardware get Gr8net (or die trying).

There are two schools of thought about that, both have (IMHO) valid arguments.
But I was mainly referring to the fact that many devices use the VHDL code that originates from the One chip MSX.

You didn't, I did. Maybe I should have used another word Smile Sorry about that.

Before the thread is completely derailed from its original subject, let's just remember that VHDL was invented much earlier than FPGAs/CPLDs, for chip development.

And that probably most of the main MSX chips (specially the VDP and MSX-Engines) where designed with some sort of HDL language too, since Yamaha was fabless. This also applies to the ASICs present on the majority of MSX2/higher models.

Lots of 80s hardware, including MSX, also make use of PAL/GAL chips, which are the earlier version of the CPLDs.
