Re: ZX Vega+ Discussion

It really is time for the public figures associated with the project to think about what is happening. A wasteland is being created in the name of justice. They really should consider the long-term implications of being associated with some of those acting in their names. Thank them for their effort...

Re: Simple AY IF Rev 7

Exolon won't play the music, if it finds an original 48K ROM. Try something like Into The Eagles Nest, which lets you manually choose 48K/128K sounds. Try this and see if you get the same value back: OUT 65533,0 OUT 49149,x PRINT IN 65533 Yes i get the same value back, does this mean the AY chip is...

Re: The hobbit: developing the parser

I helped to debug the Dragon/CoCo (6809) port of The Hobbit and I have to agree that the code is unintuitive. It would be a difficult task to convert the code from Z80 to 6502, certainly not a task for a beginner. However, there are conversions of The Hobbit to 6502-based systems like the C64, Apple...

Re: The Spectrum Show EP 70

I liked the bit where all the old DOS emulators didn't work. :D I think we forget how hard it was back then, configuring everything and managing the drivers manually. Programming was complicated by changes in the hardware and the OS, as time went on. So many hardware aspects were non-standard and so...
