Hey Jac... I came across your comments on DCC on this website and wanted to update you on some history of DCC. Specifically the Tandy/Radio Shack Optimus DCT-2000. It was not designed by RCA. It was designed by myself and a team of 3 other S/W and H/W engineers, along with an Engr Mgr. I was the designer of the Control Processor PCB that plugged into the DCT-2000 Motherboard.

-Our DCC was the only one designed outside of Philips. We at Tandy chose to design our own Motherboard, Control PCB, Front Panel controller and Display PCB. We wrote our own Embedded S/W for both the Control PCB and the Front Panel processor. Then we integrated  the Philips DDSP board, Read/Write boards and Cassette mechanism. I was also the US representative engineer that worked with Philips (Eindhoven) and Marantz (Philips Japan) & Matsushita (became Panasonic Japan). You can check out my patent  5,414,859

I can respond some more a little later....Dan Staudacher

Thank you for you comment, Dan! I understand that Ralf (Dr. DCC) recently did an interview with you and the DCC museum has received some "goodies" from you too. Looking forward to seeing them!

Hello Jac, thank you for following my #Featured Projects list!

Thanks for following our #OPC-5 - a CPU for FPGA, in one page project!

Thanks for following the Kestrel-2DX.  I suppose I should update the project page with something, eh?  LOL!

Jac, thanks for liking my Mega Sudoku!

Thanks for picking up my project on your list. I always look forward to your efforts here and elsewhere.
