Re: It's no more a MiSTery

A simple way to switch between different setups would indeed be nice. Another thing i was considering is to replace the whole config system by a system selection. You'd then switch between 260ST, 520ST, 1040STE, Mega ST2 ... and not modify a bunch of individual settings. That's imho more in the spir...

Re: It's no more a MiSTery

I suggest to buy a real MIST. The more real MISTs are being used and owned the higher are the chances for future development like this. If you prefer the MISTer then it would probably make more sense to support people in optimizing the existing core for that.

If all you want is a small and robust cubase2 solution then the MIST board may be a solution for you.

Re: MiSTery core

The 512k to 2mb settings were never really correct. The mmu was always configured by tos as it would be for 4mb. This was more like a set of defective chips in a 4mb setup with only 512k working properly. This needs some more thinking so that the ram behaves like the different ram configurations on ...

Re: It's no more a MiSTery

My personal point of view is that this new core is to perfectly re-implement the ST series. The previous MIST core will still be there with STEroids, ethernet etc... but they may stay as two separate cores. Imho that doesn't hurt. This will also make things easier as you can have both cores with dif...

Does Dragonnels demo work on a Mega ST? Or Transbeauce 2?

While playing with a "real" ikbd implementation for the MIST we found that the dragonnels demo requires the 68k to be able to reset the keyboard processor when leaving the main menu. But this requires a connection between the keyboards reset line with the 68k reset line so the 68k can use ...

Re: 68080 Apollo Core

and the question worth 100 points to you. How complicated would be porting ST core to the FireBee from the MIST? I must admit i don't know very much about the firebee. But it seems it loads the FPGA config from flash. So you'd need to permanently flash the MIST core and would then be stuck with tha...

There are a few games that open borders like e.g. obsession pinball. Imho also Lethal Xcess and/or Canon Fodder. Also all games/cracktros using spectrum 512 images need a cycle exact cpu to display properly.

Probably maybe because AMiGA have special sound and graphics chips that does not care about CPU speed ? That's one reason and the other one is that on the Amiga no such undocumented hardware tricks to open the borders were used/needed. Imho it doesn't matter why that is. But fact is that some of th...

Re: 68080 Apollo Core

What was interesting when working on Amiga cores compared to Atari ST cores is the fact that basically all Amiga software incl demos copes with the tg68k cpu core which is not cycle exact and doesn't even meet the overall speed exactly. The Atari ST software on the other hand frequently doesn't cope...

An even easier solution would be to use a digispark with i2c-tiny-usb firmware https://github.com/harbaum/I2C-Tiny-USB/tree/master/digispark and connect that to any i2c-rtc. The result could just be plugged into one of the MISTs USB ports. Of course this also needs support to be added to the firmwar...

Re: Problems with booting from floppy (atari 1040st)

Most games won't work in monochrome modes. If a game switches into color mode while connected to a monochrome screen it will usually reset the computer, then boot again, try to switch to color again, reset again ... that's probably what you see. For games you need the color cable. But the screen you...

Re: Keyboard controller

Yes. All these keyboards have the LS244 (a chip with 20 pins). These all run the $f1 firmware which we already have and know. Just for completeness i'd like to get the firmware of one of the 74LS03 based keyboards. The 74LS03 has only 14 pins and is thus smaller than then 74LS244. It seems the newer...
