Finally, it's worth noting that 'fair use' is defined both for trademarks and for copyright, but differently. The case in point is a trademark issue. There's also a difference between Trademarks (tm) and Registered Trademarks (R) Typically to use either you normally have to obtain written permissio...

Re: A3000 in-system programmable ROM -- any interest?
Another option would be to see if I can allow the host machine to switch banks, so it can access the whole 16MB (maybe with a fixed 1-2MB and a paging area above that). I don’t think the fast serial port option I was talking about will work, but paging might. If you've got 16Mb to play with, that p...

Re: AP6 curious behaviour
If you wanted to add hard drive support you'd have to pick something to remove so that it would fit. The ADFS ROM is full Full FULL!!!! Or maybe split it accross two ROMs? (I think I read this somewhere, probably in this forum). Having both an AP5&6 gives me plenty of SWROM\RAM sockets. Doesn't the...

Re: Replacement fan for A310
To be honest, unless you're fitting something that chucks out a bit of heat (like a mechanical HDD), there's probably not much point as long as the box is well ventilated.

The idea I had was to promote the most wanted things by listing them and letting people bid on them. That way if people really want them, the 'reward' price will go up and up.

I think the way the terminators work is that you leave them in place if you're not using the external connector and then terminate the end of the internal chain. I don't think you can toggle termination in software with these as you can with some podules (e.g. Powertec). The terminators will act as...

Re: A3000 black screen on power on
Do any of the keyboard lights work? Caps Lock etc? Do they flash on power up?
If not, it suggests there's an issue with the connection somewhere along the way. Maybe double check the traces from the connectors as they are pretty close to the horrible green gunk!

Try plugging in the floppy drive.
The drive will flash diagnostic fault codes via LED which may help you track down issues.
