what is the definition os a simple trigger? As for another mode to toggle to/from it can probably even be empty or rx only but a different freq than you have in mode one

I just ran through every pin one at a time with it running in continuous mode and verified they went inactive while comparing to the datasheet. Each seems to be accurate. The LA software pins are zero

That's the great thing about standards,,,there are so many to choose from! IEEE uses the same as resistor/cap color code. ICEA uses a repeating patern adding different color traces to each

It's a shame no one ever came up with a standard-ish color code scheme for large groups of wires. https://en.wikipedia.org/wiki/25-pair_color_code :) De

Let me check it all again. I did drag some pins around in the program to keep things grouped but that just moves them in place and doesn't alter the data of course. I'll check it again and upload

I was typing the same time you were....... If OE=p19 is a typo too it looks like just typos in your labeling.

Had to gig up? a 2816 and a 2864 pdf. Knowing there is a difference and remembering what exactly it is, is two different things...lol Looks like the mismatch is just your labeling, CE and WE are

I am going off the SEEQ datasheet using this 2816A pinout. [image: 2022-08-05 22_45_58-www.DataSheet4U.com (SECURED) - Adobe Acrobat Reader DC (64-bit).png] [email protected]> wrote:

Casey, Verify ypur pinouts with a 2816 .pdf If you are following the SM schematic, that pins out an 8K chip. Different setup for a 2k chip.

BTW: A more readable version of the screen shot is in "pictures" in the groups.io.? And you can download the full version, I sure can't read it after it got inserted into my message. 73's Skip

That's probably just a noise glitch. I've been looking at your trace and something doesn't look right.? For one thing OE isn't active during CE... If I ignore that as a wrong connection it still

One of these I/O lines data period is 20 nanoseconds. Hmmm...quit e fast.

Right on... So I just did a 50 MHz read. It's 124 Mb. Here is a link to it. https://drive.google.com/file/d/181wPIiCbgjQ9WymxSU898ncwmCtVNK4r/view?usp=sharing

I generally like to sample about 4x the smallest pulse I'm looking at. So if the shortest pulse (write line probably) is 100ns I'd set the sampling rate for 25ns (40 Mhz). Write being active while

OK so the CSV could be helpful but it's similar to the episode of Halt and Catch Fire where they dump the entire BIOS chip using LEDs writing each bit on a notepad. No thanks. I exported a .dsl file

I just finished rebuilding my adapter thingy for EEPROM sniffing and have all the lines labeled. It was giving a fail 84 and it turns out that if anything is wrong as in being plugged in wrong or what

For anyone that is interested I've put the source for the Xcat bootloader on github https://github.com/skiphansen/xcat_ldr. ( https://github.com/skiphansen/xcat_ldr ) 73's Skip WB6YMH

I've uploaded the Xcat schematic and bootloader hex file to the file area. This will allow the brave/crazy to build a DIY Xcat. NB: We missed the need for pullup resistors on A0 to A7 in the

Well it didn't work on my Pentium II box under XP. The box died before I could try it from DOS, sigh. Booted ONCE and ran beautifully (much to my shock) and that was it. Now it just turns off
