The original design might seem kind of brutal but it has been working for decades so I don't see a strong requirement to change it now. > >> If some of you guys would be interested in having a look at my design, >> I'd upload the design to my website.

My PCB manufacturer produces the boards in quantities of tens but 10 boards is way more than I need so I'd be willing to sell the surplus boards. Any feedback is highly appreciated. If you find a bug, you'll get your board for free. Nils Message was sent through the cbm-hackers mailing listReceived on 2017-10-18 16:03:06
