I would like to connect 2 short EL wires to the output of this pack. Do the outputs blink at the same time or is one on while the other is off? Would prefer the later, so if not, would it be easy to hack to get the outputs to alternate?

Ok my 85 is dark gray with the yellow holster. That matches the contrast they speak of. But I also have a 23, which is a yellow body in a yellow holster. That doesn’t even match the color contrast they’re going after! I don’t see a date of mfg on it so I don’t know if it was made before 2000, but I guess it’s not a Fluke since it doesn’t “look” like one.

Are you talking about something other then a sheet of pegboard at the local HomeDepot/Lowes?
Pegboard would be just fine, just don’t try to haul a 4x8 sheet home on a roof rack. I ended up with multiple pieces after the wind yanked the front end up and cracked it in several places.
Well the screen may be hard to see, but it’s a pain in the neck after awhile to keep looking down at the circuit and then up at the scope.
You mentioned a requirement for an 18" shelf to hold a scope. Looking at the height of your shelf, I would question placing a scope that high above the work surface. The closer you can get that screen to what you’re probing, the better. What about a small shelf on the left side of the existing shelf, about 10" up or so, and about 12" long? That could hold the scope and probes, and keep them out of the way. Things like a bench power supply could go under the shelf, or storage bins.

I could use that unread email counter for my wife’s email, but sadly I don’t think a 4 digit display is enough. :-)

Years ago I purchased several POS (point of sale) displays. These are large dual-sided 2x20 VFD displays that mount to a pole as part of a cash register system. Communication used an RS-485 interface and while others had managed to figure out some of the commands, I wanted full control of the display. The device uses POSLAN protocol, which wasn’t available publically. The board was 8051 based, using internal flash, but there was also a 28-pin ROM socket available on the board. By grounding the EA line I could run code from the external ROM, rather then the internal FLASH. Once my code was running, it copied itself to RAM, jumped to RAM and continued running. Now it switched the memory back to internal FLASH and performed a ROM dump out the serial port. I captured this output and was able to disassemble the code and modified it into a simple terminal program that used both sides of the display.
