Title: Bad cut on the Expansion Connector
Post by: gflorez on 2018.June.22. 11:58:58
Just because I am actually testing the bus expanders, I have discovered one more perturbing error on my second Enterprise.

I already found other error (https://enterpriseforever.com/hardware/good-looking-edge-connector/msg62898/#msg62898) on the rear connectors of the same unit some time back.

Observe these pictures:

You can realize that the cut of the board is displaced at least a milimeter to the rear in this unit. In the past this prevented the correct operation of the Bridge connector+Hardware Spectrum emulator on this Computer, but then I used to think that it was by other causes, because some times it worked flawlesly(it touched correctly the pins).

The solution is easy, the bus expander for this unit has to be trimmed at the sides to adapt it to the error. But then it will no longer be interchangeable...

Sorry, bad pictures...

Try to move the board in the case? It is possible 1-2 mms. I remember old article in Hungarian magazine, where talking about this problem: EXDOS don't work with some machine. The service center answered, bring the machine to service, and will correct the motherboard position.

Is more easy for me to trim the EDGE connector. The problem was when I didn't know it.

Wow! Talk about lax manufacturing tolerances.

The next time I open the computer I will take pictures of the factory maker stickers.

The manufacturer is FLHK:
