The ROM code is available online, as well as the extension ROMs. One can of course bypass that by building something up on a 22/44 card and plugging onto the expansion header. I usually start with a JMP 0 loop and work my way up. Thanks, Jonathan On Sat, Nov 10, 2018 at 10:52 PM Henry S. Courbis via vcf-midatlantic < vcf-midatlantic@lists.vcfed.org> wrote:
Greetings and Salutations People Of The List:
I hobbyist recently contacted me about a project they are considering which is a clone of the AIM-65. However I'm mostly useless to help since I have little idea how the system works, or should work. Sure I can help clone it, but that's the "simple" part. Being able to check if it's working is kind of where the magic happens. Putting parts on a board... not so much.
For a starting point they have an old unit which doesn't work. We found this link for schematics: http://www.originalwoodworks.com/aim65/
They have checked the PSU and some obvious things like this, as well as replaced some of the standard ICs which were suspected to be troublesome. We don't have any ROM code to validate the ROMs to or to burn new ones. And we're both kind of in the dark as to how the system should even work, which is kind of the fun of this adventure. If you can't break a toe and bruise a shin while stumbling around in the dark for the light switch, then what real fun is it?
So anyone have any advice or feedback as to getting the system to at least want to seem alive, what known trouble ares there are, to yell at us for being silly geese, etc? Please email us offlist (his email to CC: tld10091 AT gmail.com). Thanks!
