Simple: one or two of Jim's boards and a dip switch hot-glued to the back of the C64. I have an AIM65 that selects one of four different languages in ROM on power-up that way, and a 2001 PET that combines the 14 ROMs of BASIC 1 and 2 in one 27C256 EPROM, selectable with a single jumper/switch (albeit with a few jumpers to the main board), both using one of Jim's adapters. mike ----- Original Message ----- From: <email@example.com> To: <firstname.lastname@example.org> Sent: Monday, May 14, 2012 3:58 PM Subject: Re: 6569 luminances On 2012-05-14, at 21:41, MikeS wrote: > Anyway, the point that's gotten lost in this somewhat picayune discussion > was that instead of making your own 23xx ROM replacement board with pins & > socket and a 74LS11, one of Jim's adapters will do nicely with maybe one > or > two minor mods, and also save considerable power. What I would need would be at least two KERANL images, plus both CHAROM and BASIC. But I am still waiting impatiently for someone to design the board that could be used to select the uploaded ROM images on power-up. This would be best of both worlds - power efficiency and unparalleled versatility. Volunteers? -- SD! P. S. Point, which seem to be even more lost in this discussion is my original request for someone to check and photograph the various VIC revisions' output... ;-) Message was sent through the cbm-hackers mailing list Message was sent through the cbm-hackers mailing listReceived on 2012-05-14 21:00:27
