ADTPro - Super Serial Card

Hi,

I've got a Super Serial Card, and I'm having trouble with it. I went on the ADTPro website, set the jumper block to down(straight through cable).

Then I set the DIP switches to as shown in the photo on their site. 1001111 1101100.

I've tried the following in slots 1,2,4,6. All yield the same result. Also, Slot 6 was where my floppy controller was, so I know that slot is OK.

I type IN#2(in slot 2).

It accepts that without any issue. Then I hold down CTRL, and press A. When I release, I get a new line, and the previous line has a blinking white box where the cursor used to be,

I get no Apple SSC: prompt. I just get a standard line.

This is an official Apple Super Serial Card, made in Singapore.

Are there any more troubleshooting steps for me? Should I just buy a new card?

Best,
George

I apologize. It is an Apple IIe Platinum.

Re: ADTPro - Super Serial Card

So I believe the problem is not the SSC.

I used Audio Bootstrapping to get the Serial Client in, and everything went fine from then on.

I've just realized however, that anytime I press Control, the program breaks. To me, it seems like the Reset key is always "active" and when I press control, it breaks the program. Likewise I only need to press Control and Apple to get a cold reset.

What do I do? Is this an issue with the actual keyboard? An IC? What are some potential diagnostic steps here?

Measure the Reset button contact state.

Thanks for the tip.

The Reset key was shorted closed. It looks like a screw was missing that is needed to keep even pressure between the keyboard and the PCB. I added a screw, it caused the key to behave normally.
