Re: Core PC/XT BETA para ZX-UNOs con 2MB

I replaced the internal 2MB SRAM AS7C316096C-10TIN for IS61WV20488BLL-10TLI and the core seems to be working stable on 75 MHz. I have just trouble with games. From the few, that I have, only Prince seems to work OK. Even the LSL which seems to be working accoring to info in the cloud spreadsheet is ...

Re: Core PC/XT BETA para ZX-UNOs con 2MB

There is no need to run any memory test, just run some games and check that the core doesn't reset or hang. I tested the 60 MHz core for about two hours yesterday and it seems to have more troubles with core compatibility than freezing or resetting. Some games work, some not. Could it be possible t...

Re: Core PC/XT BETA para ZX-UNOs con 2MB

I wanted to test the memory by some DOS memory test, but I cannot find any working. Checkit seems to work, but not its memory test. Norton Diagnostics behaves strange and freezes. GoldMemory freezes. Do you have any working test, that I could use to prove that the current core frequency is working s...

Great, thank you.

50-65 MHz boots OK, seems to work - I will have to test it more
70 MHz write 7 text "BIOS" lines ending with "PS2 KB detected" message and freezes
75 MHz black screen

Re: Core PC/XT BETA para ZX-UNOs con 2MB

He montado la expansión de 2 MB y sorprendentemente funciona de manera estable a 75 MHz. He añadido dos documentos al inicio, uno para anotar el software probado y otro para anotar la frecuencia a la que es estable cada expansión, para que compartáis vuestros resultados. Could you please make the t...

Re: Zx-Uno VGA 2M

Could you fit 2 PS/2 connectors, so there would be no need for a splitter cable for mouse and keyboard?

I´m tested today four PCB and works fine with ISSI memory , problem with your model maybe?
