Gottlieb Sys80 Universal Tester (Leon design) -- MPU Diagnostic Tool

Well...I use Ed's tester, which is awesome, and really don't have need for a different tester. I've been so happy with Ed's that I never investigated Leon's process. Before your work, which looks excellent, it was a lot of work to implement Leon's test.

Ed was working to port his tester to a new chip set, IIRC, to address obsolescence.

Why is that daughter card in the U2 positioned?

Quoted from G-P-E:
For several people that have been asking -- the QS80 Ver 3 is nearly ready.
Bit more software testing before it can be called done.
Ed

Looks sweet Ed. I'm in!

I have the OshPark bare board...just haven't populated it yet.
That should be straightforward. Just need the time.

I built mine out a couple of weeks ago. Beautiful little device. Works like a hose with Marco's ROM.
I sent one to Palson too. I didn't know that he already had one. Mine was built better...

Here's my first build out. I used a socket for the 7404. That required me to raise the EPROM socket as high as I could. The second unit I built, I soldered the 7404 in directly. It fit together much nicer.

Quoted from fast_in_muskoka:
Might not even need the tester,

Blasphemy! If you own pins, you need these testers!
Said somewhat tongue in cheek, but they really do come in handy.

Here's a short video of the tester working in a correctly operating System 80A MPU.

Here's my interpretation of a "users guide". The description Marco provides is a bit confusing.
One long blink - ROM is running.
Short flicker followed by a longer single blink - 5101 tested good.
Short flicker followed by two longer blinks - U4 tested good.
Short flicker followed by three longer blinks - U5 tested good.
Short flicker followed by four longer blinks - U6 tested good.

I had emailed Marco about adding his tester info to the PinWiki, similar to the way we've added Leon's test articles, which we added verbatim. But Marco plans to create his own page. I thank him for the work he's done on the ROM, and him making it available to us all.

I/O tests.......

Thanks Marco. The additional documentation really adds to the tester. Very slick.
