Re: Oric Atmos core

Ok thanks, but i give up makes no sense. Someone will fix the Issues I'm sorry to hear that, but I undertand your frustration: without a working MiST it's near impossible to debug the cores. Unfortunately most of the MiST users (including me) don't have the necessary knowledge to help you during po...

Re: Oric Atmos core

Hi!

Cannot test it right now (I visited my mother-in-law with my family taking advantage of the long weekend 'cause Pentecost), but will try it as we get home, tomorrow afternoon or morning!

Thanks for your work!!!

Re: Apple I core

The main problems are in my opinion that nobody who is familiar with original systems (Apple One and Orao) is interested to help porting these cores, and without a working MiST it's near impossible to complete these (or add similar) functions. As usually, I'm very grateful for your tireless effort m...

Perhaps it's because the Vectrex was not so popular and marketed only in small quantity (no one knows exactly, but certainly under 500000 pieces were sold, see details here: http://atariage.com/forums/topic/59575-vectrex-numbers/ ).

Re: Vectrex vhdl

Hi!

On my MiST+BenQ BL912 combo it works flawless, albeit the picture is a bit off-centered to the right (see screenshot #1).
Video output is unusual 640x500@57Hz (screenshot #2), which ruins compatibility with most monitors.

Thanks for your continuous effort to make this core better!!! :cheers:

Re: Some interesting vintage computer's FPGA reimplementation

Nice findings! If EAR input would be implemented I assume the first thing to do would be to build an adapter based on the wiring diagram attached. I own a mist 1.3 without MIDI interface, so there won't be a problem to connect the daughterboard to the motherboard. But this is obviously not a solutio...

Wiki says that Compukit UK101 used the Kansas City standard tape format: https://en.wikipedia.org/wiki/Kansas_City_standard This was popular method at the end of the '70s-early '80s, and many computers (i.e. Acorn Atom/Electron, BBC Micro, MSX and Z80) used the same system.

Hi! Yes, this core seems to be incomplete. The startup screens is full of @-s, but at least the video output is 640x480@60Hz. The other two cores look more mature, the UT-88 can load .wav files, I'm not sure if this can be implemented or not... (perhaps similar way as Sorgelig's ZX Spectrum or your ...

Hi!

The modded core seems to be defective: the title screen is corrupted, and cannot start any ROMs I tried (i.e. Frogger, which works great with previous release).
