MP3s and Ethernet 17 23 (8/24/2006 7:53:55 AM) comp.os.cpm Is anyone here interested in the idea of a S-100 card with an ethernet chipset and mp3 decoder? I thought it would be fun. It would be easier if some developers out there had too much spare time and money. ;... logjam

Tired of GSE-REACTIVE? 41 37 (8/9/2006 10:39:36 PM) comp.sys.apple2 A new Apple II retro store will open soon that will sell everything Henry has, but at least .1 times better. For example, Henry sells RAM cards that don't have even a single LED on them. How in the world are ... logjam

Blinking Light Apple II 43 24 (5/19/2006 7:29:40 PM) comp.sys.apple2 I think it would be neat to have a control panel on an Apple II like the Altair and IMSAI computers had. What do you guys think? Since it doesn't have to be a replica of anything the operation of the panel co... logjam

VHDL simulation 2 53 (2/17/2006 2:38:45 AM) comp.arch.fpga I have a schematic of a 4bit adder in my CAD program. It has the ability to create a "VHDL schematic netlist". I've been trying to find a software package that I can use to simulate this schematic. It says "... logjam

FPGA Altair Advice 14 93 (1/13/2006 9:10:01 PM) comp.arch.fpga I was working on a Macintosh clone project (a clone of the original 128k), but I'm not willing to invest any more time in something that Apple would probably kill with a C&D order. I'm now working on a hardwar... logjam
