Back in the heady days of the first boards, many interesting ideas were bandied about for much needed PC532 peripherals. My two faves were the Moto 56000 DSP board and the i860 intelligent frame buffer. Whatever happened to these? Just curious.. I'm well aware of how wide the gap between wanting to do something and actually having the time to do it (as is evidenced by the virtual standstill our BSD porting project has come to). Still, it would be real nice to get a frame buffer at some point. Jordan

I was wondering when someone was going to ask about the 56001 stuff... I have made quite a bit of progress on it, even getting another (more hardware type) person helping me. However, I had to put it on hold because of school, big job change and a project coming up that was going to pay. It has not been forgotten though. I am going to finish building my pc532 before I pick it up again. Enjoy...

I've talked to Dave and George about a frame buffer based on Intel and C&T silicon, but as much as I'd like to work on it, I really don't have time right now... or any time soon. > Just curious..

In the meantime, I've got several renditions of a block diagram for what I call the "Kitchen Sink Card" on my CAD system. The intent is to make a really cheap do-all card to provide a set of standard, stupid interfaces that I need that aren't on the pc532. Things like Centronics parallel printer ports, a LAN interface, a floppy interface, etc. My favorite scheme so far involves an NEC V50, 1Meg of DRAM, 2 byte-wide ROM sockets that overlay the top of RAM space to provide either a bootloader or a full set of firmware depending on the size parts you want to use and your attitude... 2 Centronics ports, thin LAN, floppy, SCSI to talk to the bus, and the serial port on the V50 brought out for a debugger interface. As much as I hate the 80X86 architecture, I've got the tools and loads of embedded system runtime code lying around, and a ready source of cheap V50's. Plus, the part has all kinds of really neat stuff onboard. Personally, I believe that for this kind of interface card, the V40/V50 provide lots of bang for the buck. Whether I'll ever find time to get beyond a block diagram is very much in doubt. But, it's fun to think about... :-) Bdale

I have a DSP56001 question: Motorola published an app note for a 10 band stereo audio graphic equalizer with the source code. Typing in the hex code looks daunting and I don't have a 56001 assembler. Would you know of someone who could send me the binary code in something I can mangle and send to an EPROM programmer?

If you snail-mail me a clean xerox, I'll try to scan it for you and e-mail the ascii. 8329 ivy glen court, manassas va 22110

Have you checked the Motorola DSP bboard? The microprocessor "freeware" bboard has lots of good stuff. I don't have the number for either bbs on hand, but I remember that the freware bbs tells you the number for the DSP bbs when you connect.... -Phil
