I no longer have an original ORG 0 board but I do have a few of Les’ H8-64 RAM boards which are only 3-1/4” wide. One has the SAMTEC edge connectors and one has Molex (like the original Heath boards). Both seem to stay very nearly perpendicular to the backplane when inserted – certainly no risk of interference with the card behind. I would still caution against putting such card in the back-most slot as it is only a few mm away from the (grounded) steel power supply cover. As I recall, Heath solved this problem on the Org 0 board by designing it to be installed with the component side to the rear and with a rubber “bumper” foot adhered to the board to ensure clearance.
Having said that, I thought that the “feet” (small extension on the PCB at the bottom) you placed on your shorter boards did a nice job of solving this problem!

OK, I will add the leg to it. Thanks you!

On seconds thoughts, I think it will work without the leg as it is small. This is how it looks.
This board can use any of the 3 types of connectors.
Thanks,
Norberto

so say more about this third style edge connector. I’m only familiar with the original (Molex) and the newer Samtec… what are the advantages of the newer connector?

Good project to learn on how to remove the mask on both sides of the connector to solder a straight angle 25-pin connector.
At the end of the day learned something completely new. 🙂

Glenn:
That is the "Blinkenlights" controller, made neat and compact by Norberto's skilled hand.

Subject: Re: [sebhc] Heathkit ORG-0 card inserted behind CPU board.As it is a straight connector it should allow to insert small modules between the two main slots in the new H8 backplane to avoid consuming a regular slot. This new connector is a Samtec straight angle connector. .
Same idea as the Heath ORG-0 card.
