Bring Your Apple II Work

You should bring your Apple II work. There’s nothing wrong with the idea. Yesterday, I had mentioned that I had brought an Apple IIc Plus as a cube-side companion.  I had set it up, using a DVD player as a LCD display.  The display is highly portable, but the dispaly quality definitely takes a hit.  The big benefit is that the whole deal can jam into a reasonably sized laptop bag, you know,  for the Apple II ambassador to the world on the go.  Setting up the serial video streaming rig is straight forward:  RS-232 compatible connection from your PC connected to a IIc MiniDIN8 connection (Trivia:  The RS in RS-232 stands for Recommended Standard.  Early on, this was a +/-10vdc signal that sometime got driven at lower signal levels and lead to communication problems.  Soon a +/-5vdc driver appeared and became known as RS-232 compatible).  That’s about it on the hardware side, so let’s review the inventory:  An Apple IIc, a display of some type, an Apple IIc serial connection (RS-232 DSub-9 to MiniDIN8 cable.  You’ll want one for ADTPro anyway,  available here).

On the software side, your are going to need vnIIc.  The software is step by step easy, and the site does a great job of documenting what you need to do.

Earlier this week, I covertly deployed this rig in the cube at work.  I experimented with single frame displays, and streaming the YouTube corporate video channel.  I need a better monitor, though, as the little LCD isn’t very crisp.

An idea was brought up to video the exercise and post it to YouTube, poetically bringing the whole thing full circle.  Armed with a few spare minutes and my n900, I set out to get some mediocre shots and fix the whole thing in post production.  I need a steady cam.

The Resulting Video is hereby tendered for your review.

 

Binary Hexarhythms

I have begun reading a book entitled “Artificial Intelligence on the Apple II”.  It is interesting to me and does a reasonable job of explaining the workings of it’s schemes as far as informational management.  Concurrently, I am also looking at a few Nibble Books that I purchased from Mike Harvey.  I haven’t met the man, but he has always been quite personable in e-mails and I have found his products to be of great value to me.  Particularly the OCR searchable complete Nibble magazine library on DVD.  Recently I purchased a few nibble books on DVD.  I chose a few that I felt would have the most strategic and tactical value to me and it came to a reasonable price.  These books are well written, and quite an asset as I experiment with ideas.  Continuing with my Apple II Attention Deficit Disorder, I was going through some Apple II programming documents about different means of sorting binary values that I found in the Asimov FTP site AppleII Documents folder.  All of these bits of information went into my Apple II mixing plenum, and got processed by my subconscious.

Tuesday, I had difficulty sleeping.  I turned to a new technique for me: counting in binary.  It’s how I did it that was strange.  I let the for fingers on my hand represent switches and I incremented the bits as I counted:  No fingers, Pinky, Ring, Pinky/Ring, Middle, Middle/Pinky, Middle/Ring, Middle/Pinky/Ring, Index, Index/Pinky, etc., etc.

I think that this method has a name and really was just a binary version of “Chisholm bop”.

Eventually I picked up on the rhythm, steady and trance inducing.  The rhythm slyly made it’s way into my cerebral cortex, seductively tempting my brain with something that was just out of reach.  I couldn’t see what it was.  And then the seventh veil dropped.

I have never been really fluent with Hex to Binary conversion but now I have a new tool that is going to help me.  It’s a conversion table my brain saw.  Just make a 4×4 table of hex counting $0 to $3 left to right and continuing to $F.  Now count to 4 in binary on a header row and column.

___00   01   10   11
00    0    1    2    3
01    4    5    6    7
10    8    9    A    B
11    C    D    E    F

Find the hex number of interest and read the left column and top row.  For example: B is equivalent to left column 10 and top row 11.  1011.  It’s too simple not to have been written about somewhere else, I am sure, but it’s sure was cool actually seeing it in my mind as something new.  Now, when I am teaching people about addressing ADIO’s I can give them a tool than will help them when they need to set the switch to address $2D.
