Lol... my ears perked up at wondering what the state of some of the PIO cores might be and I googled vhdl and 6522 and the first hit was a post from André from 2005 on this board. -----Original Message----- From: firstname.lastname@example.org [mailto:email@example.com] On Behalf Of Ethan Dicks Sent: Friday, May 01, 2009 11:43 AM To: firstname.lastname@example.org Subject: Re: 90x0 On Fri, May 1, 2009 at 10:44 AM, "André Fachat" <email@example.com> wrote: > >> Wow.

I've seen that. It looks very interesting. I'm personally not opposed to using GALs to reduce part count, but I own multiple burners and I've been working with PALs since 1984. It's a technology I'm comfortable with. > I still think it is possible to put the PET into one FPGA > and some day I hope I actually manage to do that That sounds entirely do-able, but it is beyond my skills to engineer - I could construct it, but I wouldn't personally attempt that as the sole designer. I know the 6502 core is done and available, but I don't know about the 6520 or 6522. -ethan Message was sent through the cbm-hackers mailing list -- This message has been scanned for viruses and dangerous content by IDSi's MailScanner.
