Re: Beeb 1MHz Bus FPGA Adaptor

But i think it's becouse of Integra-B, since i use that board it freezes sometimes... tomorrow i'll give a try with my others micros Your IntegraB shouldn't be causing your computer to freeze. This will give me the motivation to build up my 1MHz Bus FPGA Adaptor, just to confirm it works with the I...

Re: Beeb 1MHz Bus FPGA Adaptor

Thank you Dave, resoldering a couple of connector's pin and reinserting the cable a few times did the trick! Now beeb boots and Mandel3 works, but it often hangs and the owl logo appear only for a second when resetting, then disappears.. sometimes, while resetting, the screen shows the Owl and beeb ...

Re: Beeb 1MHz Bus FPGA Adaptor

I need some help again... AtomFPGA runs fine, but something wrong when adaptor connected to the Micro: - With Music5000, Micro doesn't boot. It boot only with IRQ jumper not fitted, but no Owl logo in this way, of course; - with Mandel programmed, it boot but "Mandel3" doesn't interact with vga scre...

Re: SmallyMouse2 - new firmware release

The issue is that you need support for USB in 'host' mode - which (afaik) only the AT90USB1287 provides. On the bright-side, because it's an open project, there are lots of SmallyMouse2 boards for sale on ebay as well as other sites on the web (if you want a preassembled and/or cased one). Thank yo...
