super serial card

[scroll1]

I have an Apple IIe enhanced as well as a normal IIe.

The duper serial card works in the normal IIe, when I use ADTpro I type:

]IN#2 (in card slot 2)

] (ctrl -A)

and I get to the SSC: command prompt.

Everything works well.

However, if I place the same card into the enhanced IIe model and trying various slots, I cannot get into the SSC prompt.

Can anyone make a suggestion?

Thank you

Does the enhanced IIe work normally otherwise? Have you tried any other expansion cards in it?

The machine seems to be functioning correctly. The strange thing is, I can get the serial card to work booting from an ATDpro floppy and choosing serial. It then communicates with the XP box no problems. That floppy was made on a standard Apple IIe. So the card works in the slot, I just cannot get it into SCC mode by typing:

IN#2

(ctrl-A)

thanks for any help,

Wayne

actually, I'm beginning to wonder if my "control" key is actually not working properly. It does beep when I press control-A but places a faded block cursor at the prompt and then a full coloured rectangle cursor blinking 2 lines above the last line....

Is there any test I can run on my keyboard?

=====================

ok, confirmed: my actual keyboard is at fault, I hooked up a standard IIe keyboard and ctrl-A gets me a SSC: prompt.

Now does anyone have a clue why that would be?

Key switch is not so good on the control key, I think. I had the same problem with a //e I received a few weeks ago. The 'W' key would not work for almost 2 weeks, then suddenly it did work. Could be dust, grime, or other stickiness lurking below.

Sometimes, if it's just a dirty switch you can fix it by "exercising" it.

Thanks for all your suggestions.

Now having tracked down the problem to the keyboard, I pulled it off and blew it out. The key is functioning correctly (testing with a multimeter), but There must be something else wrong on the keyboard circuit. I did "exercise" it for a while. But when it is plugged in I get a definite beep response from pressing the control key, I am not sure what it thinks has been pressed and whether that beep is an error.

I looked over the circuit board from the back and it is fairly clean except for some dark marks around the ribbon connector.

I suppose I am just on the hunt for a replacement keyboard.
