Here is a photo of an "impossible" Apple-1 daugther card under development in my lab:
The riddle - and the challenge to y'all - is to answer 3 questions, by commenting in this thread:
Q1: Which kind of peripheral card is it ?
Q2: Why is it believed to be "impossible" (for the Apple-1) ?
Q3: What does the screen contents mean ?
If there are at least three answer posts, each with at least two of the three questions above correctly answered, I will post more information about this development. And everybody who did answer at least two of the three questions correctly, will enter a sweepstake from which one winner is drawn.
This winner might receive the first production version of this daughter card from me as a gift - but no guarantees are made that this will ever happen. So you may get nothing even if you "win". The reason for this disclaimer is that I don't know yet if it ever can be made to work well enough to be a viable "product" - I don't want any marginally working gadget on an already quirky host system. And the next obstacle is whether there ever will be enough interest among the worldwide Apple-1 crowd to justify any PCB layout effort.
(BTW, it's not meant to be a money maker ... I just sought another "mission impossible" to keep my skills with various CAD tools and digital circuit design techniques sharp. These mental skills are like muscles ... use them or lose them. A real danger for retired people ... I've seen once brilliant engineers turning into dummies within a few years after their retirement. And this was not due to Alzheimer or such. It was due to mental sloth and rotting their brain away in front of the TV. The human brain quickly adapts to the abysmal IQ level found in there. Be warned ! (No April fool's joke, this warning !)).
But now back to our riddle. See, I want to keep your brain healthy, too !
Here is a proposed format for your answers (with a few hints, as I want to be fair):
A1: It's a ______ ______ peripheral card.
A2: It's "impossible" because Apple-1 has _______ DRAM _______.
A3: The screen shot shows ______ ______ from _____ _____.
You see ... very easy ! ... just fill in the blanks !
Good luck solving the riddle !
