Apple II Single Stepper

Apparently this was used in test engineering.
In Ireland.
The single stepper was used in the rework area -
failed motherboard would be examined by the
technicians using the single stepper and
could determine the fault. (RAM, shorts, opens)

Thanks for the reference, it's quite interesting.
The article mentions that you can add a display
board such as the one from John Bell.

Can you tell me the name of this board?
Will it work with a IIGS?

I think it was just called the John Bell Engineering Display Card.
Anything that reads out the Address and Data lines would do. Just buffer the signals and feed to individual LEDs or decode to hex displays.

Could be used in a IIGS, but without decoding/displaying the current memory bank as well it would be less useful.

I did a search for John Bell Engineering Display Card and
nothing comes up. Are you sure that is it?

Also, I have just checked the price for ebay of paddles.
$265!!!
Are there any other options?
