Apple 1 Mark V

[Chris Davis]

This is my fifth attempt and I think I've got it now.  My last attempt was failing because (I believe) my PS2 keyboard port was getting interference and not working most of the time.  So I ditched the PS2 and went with USB which was, surprisingly, easier than I thought.  So here it is:

Still to do:

1. Change display to 40 character (currently it's 80 characters.)

2. Get SD card module working

3. Invent some method to emulate the cassette commands to load from the SD card.

[Brian Decker]

Looks great - very happy to see that you are going to USB and not staying with PS/2 (you know my thinking on that - based on my own production work :) ).  Will be picking up several once they are available!

[Charley Jones]

Great work. Congratulations.

I prefer an 80 character display... please tell me you’ll at least make that switchable. =)

Great work, Chris.

Will VisiCalc be on the list?

Um, good luck finding a copy of the Apple 1 version of VisiCalc!

[Michael W. Salter]

I used it on an Apple II.   Then got the CP/M card and used Supercalc.  One can always dream!  The poor guy that wrote it didn’t realize what he had with VisiCalc. 

[John Kennedy]

Oh yeah!

[Chris Davis]

I don't think that would work.  It's running the original code written by Woz (the monitor and Integer Basic) which was designed around a 40 character display.  Having an 80 character display would mean only the left half would be used.

[Chris Davis]

On the plus side, I got the SD card module working.  On the down side, I realized I have to code an entire Apple font by hand (unless someone has a source for the Apple II font glyphs).

[William J. Steele]

How about this: http://www.kreativekorp.com/software/fonts/apple2.shtml

Apple II Fonts - KreativeKorp The Ultimate Apple II Font. Download the world's most complete Apple II text font, in TrueType format. Works on Mac OS X, Windows, or any operating system that supports TrueType. Also download the corresponding keyboard layout for Mac OS X, called IN Number Zero.

If what you want is the actual Signetics 2513 character generator bitmaps, as used in the Apple 1, early rev Apple II, and many other machines, they're in the attached binary file and PDF.

[Charley Jones]

Such a damn good community. Happy to be part of it.  Looking forward the kit.  Now to craft a proper 3d box for it... 

Please please please make sure it has a great expansion buss. The community did such a great job with the Altair’s VT100 expansion.

[Chris Davis]

I have the glyph images, but having them in a grid like that will be helpful.  Is the BIN file a MacBinary font file?  I guess what I'm looking for is the hex encoding, like this example:

{ 0x00FC, 0x0012, 0x0012, 0x0012, 0x00FC, 0x0000 },     // A

{ 0x00FE, 0x0092, 0x0092, 0x0092, 0x006C, 0x0000 },     // B

[Frank P.]

So HxD followed by a few minutes tidying up in vi yields:

{ 0x00, 0x0E, 0x11, 0x15, 0x17, 0x16, 0x10, 0x0F }, // @

Holy cow, I did not expect to get it on a silver platter!  Thanks, that's perfect!

Well, it's close! :)

I found a program called MikroElektronika GLCD Font Creator that generates the code I need.  Thanks!

That's what I needed!

What kind of bus do you have in mind?  Like the RC2014 bus?

A real Apple 1 has an expansion bus with two slots, one vertical (socket) and one edge. It would have been possible to add an expander to provide more slots, but I haven't heard of any being made.

[Belknap Knyss]

omg I want that ;)

(this google groups thing user interface should cite Chris' original post with a graphic showing a very interesting permutation of the font glyph set).

My (assembled) kit shipped so I'll be very interested in what goes on in the group. ;)

Vaguely thinking about a Forth for this rig and maybe ROM'ing it (no idea how).
