The PCXT core is cycle accurate in its 4.77 MHz, 7.16 MHz, and 9.54 MHz modes, but is no longer cycle accurate at maximum speed (AT like performance).

Make sure to use SFTP or some files may not transfer right

Looks like there are some cores already ported to it...
No SNES yet, though:

Try using two separate power supplies to rule out a splitter issue or not having enough power.

Also see if it works disconnecting the USB board to the DE-10. If both power up maybe there is a problem with the bridge.

Also some TVs are picky with the HDMi signal.Make sure you use a default INI with the 720p output and vsync=0 first.

Is there a recommended BIOS set everyone is using, to get this core up and running ?
Never had a PCJr, or Tandy, but have owned DOS PCs in the late 80s, and early 90s.

I use the Tandy BIOS by default on my setup.
You can get it by runnig the .py file provided in he core repository.

Are those needed though? Gyurco does mention the DE-10 / Cyclone V handles the original HDL better than MiST

I had an external 3.5" drive on my Laser 128EX as a kid and it was awesome! You could hold so many programs on one disk, and they seemed to be less prone to read and write errors.

Right but the core also support hard drives - you can just mount a 32MB hard drive and store whatever you want in it

The Z80 card is basically to use the cpm operating system with 80 columns. Widely used at the time. Microsoft sold thousands of cards.

Just remembered that CP/M already runs on the Multicomp core on MiSTer;
was there something special about the Apple version?

The new core works so well - we can play French obscure RPGs now!

Ah yes - I had that issue with screenshots too
