I'm unable to see the pictures... your server seems to be down. Such a breakout board is a nice idea. But I'd include buffers for all signals and fuses for the powers to protect the Apple 2. And I'd use a 68-pin cable where I'd put the power lines between the high freqency signal lines: 16 address, 8 data, 3 strobes, R/W, 4 clocks and 2 interrupt signals yield 34 pins. the other 34 should be reserved for power. This way interference between adjacent wires is reduced allowing a longer cable length. --- Ferdinand --- Synchronet 3.14a-Win32 NewsLink 1.85
Hi ..yes my ISP is moving server instances to new hardware this weekend ... things should be back in awhile.
thanks for the feedback ....I was trying to keep things simple/flexible as possible and wanted to keep it strictly pass through .. being targeted to the folks who would sacrifice an old disk II controller just to get an edge connector.
I see myself using the side pins to attach Analyzer leads and the top card edge to solder a female dual row socket .... I will then use the 90deg header mounted on perf board to plug that into the female socket. Being content to have my card under development sticking out the top of the case.
I will give your suggestions some thought and maybe integrate them or come up with a second version of the breakout board.
Thanks again ... Glenn --- Synchronet 3.14a-Win32 NewsLink 1.85 A2Central.com - Your total source for Apple II computing.
