Re: The last MIST

It's true, an FPGA board is to some extent independent from its cores. The MiST was developed exclusively for the ST core at first, but like Minimig the core can be ported and thrive in other boards. That said, one needs a motivated core developer to carry the torch. The MIST innovated in many aspe...

Re: SDRAM+SRAM board (only concept for now)

I also know many smart words :) The difference between knowing some terms, and making a real hardware is huge. Good luck to find SSRAM in TSOP or similar soldering iron friendly package and make it run at 200MHz on MiSTer module ;) I even don't say about price. Well... technically... 167MHz and TQF...

Re: SDRAM+SRAM board (only concept for now)

If you want to achieve the highest speed, SSRAM is IMHO much better than old async SRAM. But you will still get, at least, one cycle lattency. This FPGA is too slow for reading on the very same cycle at very high frequencies. But it is one cycle latency on a memory controller, which runs 150-200 MH...

Re: No Atari ST core?

[ So why is there a section for MiSTer on this Atari 16/32 bit forum then?? :shrug: Especially as it's under FPGA-clones, but ... there is no 16-bit Atari core for it so it's not an Atari clone and seemingly never will be?

Re: MiSTer: MiST on Terasic DE10-nano board.

Sorgelig, while I'm here.. I haven't finished my 68000 cycle accurate code yet, and my new core is system verilog based. As a stop-gap, I've re-written and tidied up the TG68K (renamed as M68K so I can track it). It's in regression testing now. Ping me and I'll send you a copy for testing as soon a...

Re: Mist expansion (in theory)

This question is only theoretical. Hopefully FPGA development won't get abandoned for the MISTer only. I thought about the Vampire cards for the Amiga 600. Lacking a card slot (obviously) on the MIST, what in theory could expand it's power and functionality? Could a hobbyist pcb with the right conn...

Re: Testing: Support for more HDMI resolutions and other changes.

I never expected it to be trivial :D Just looking at the prices of the XRGB and OSSC show that good quality upscaling is very difficult. In theory 720p is an ideal ratio for 15khz because 240px3=720p. I wonder if I will get better results if I disable the scandoubler option, because maybe its upsca...
