The 74x244s on the outgoing side have there OE attached to WROE. Thank you very much, for doing these. I had thought it was a windows only app, Thankfully I learned otherwize.
I have updated the top post to show the better schematic.
Make a .pdf file for your top post schematic.
I use Eagle to make a .pdf which is much easier to read than a .png. Just use file->print and specify pdf as your target.
I use Eagle because the $45 license allows me to produce boards for profit that have 2 layers with any number of holes and certain size restrictions. The open source "gerbv" program is great for checking gerbers for silkscreen placement and common errors. Make sure to use the ERC and DRC tools to check your schematic/layout. It's easy for wires to be "close but not connected in" the schematic.
Many people like diptrace. I may learn diptrace some day because of the 3D stuff, but I'm very happy with Eagle.
One of the first rules of posting forum images is never to use JPEG for diagrams. Save that for photos. For diagrams, use GIF, since it employs lossless compression. PNG can also work if the compression you specify is lossless. (Lossless PNG files tend to be larger than GIFs, though, in my experience.) Stay away from TIFs, unless you're trying to weed out our dial-up forumista friends!

When I try to print a PDF from Eagle using either the CUPS PDF printer, Adobe PDF Writer, or Print to File (PDF) it does not print the labels. To note I am using Linux 2.6.33.2 with x11R7.2, and CUPS 1.4.3.
Phil:
That was uploaded as a lossless PNG, for some reason every time I upload a PNG to this forum it gets converted to a JPG. I do not use GIF because I do not know which GIF formats fall under the Compuserve Patent, that has caused many of us grief in the past.
Tip-o-day: You can place an overbar in Eagle schematics by enclosing the name in exclamation marks... !RES!, !OE!, CS!0!/1etc.
I stumbled over that when I tried to put "!nSocket" on one of my DIP32 modules.
Had to spell it "\!nSocket". I use " * " as in RESET* out of old habit.
Phil:
I am still having my GIFs converted to JPG. See atached screen captures (screen captures uploaded as PNG), though I can upload ZIPs using SeaMonkey.
The only thing I can think of is that it wasn't a GIF to start with. Saving a file with a GIF extension doesn't necessarily make it a GIF file. In most "Save as..." or "Export as..." situations, you also have to select the file type from, say, a drop-down box.

It was saved in GIF format using mtPaint, which forces you to get it correct, as it does not just trust the extension, I still have the GIF and the file size, and quality are radically different, the GIF is clear has a B&W palette and is 49KB.
Sorry about the missing post (I had typed it though forgot to submit it, it would seem).
The usable schematic is now posted in the top post. I hope this is helpful to someone at least.
To help clarify the reasoning for doing things this way: I realized very quickly that using 24 pins would be very restrictive, as ATA is not much use if you can not due anything else with the same Prop, so the multiplexing brings it down to 16 pins total. This is part of my MultiDB68K Amiga 68K clone, the same prop is also used for the audio output and input, with another Prop for video, keyboard, and mouse, and one for serial, USB, and simulating the Amiga Copper, and finally one to read/write main memory, convert the Amiga memory mapped registers to the commands used by the other Props, and communicate with the other three Props.
I didn't have any issues uploading a GIF from Linux Mint under Opera. I do seem to recall, though, that the forum software will convert files that exceed certain physical dimensions to JPEGs by default. That may be what you're experiencing. What are the pixel dimensions of your GIF?
Comments
I guess I did not edit my previous post in time.
Also would you mind converting this to PDF, my PDFs do not come out correct.
Unless I overlooked something else here is the final.
Also thank you for introducing me to Eagle, I had not previously tried it, and I think I could get accustomed to it.

GIFs have been free from their money-grubbing, monopolistic bonds ever since.

Opera 11; OS = Linux 2.6.33.2 + X11R7.2 + JWM.
Phil, it is unfortunate that most of us live in a money grubbing society.

The GIF is 2557x1657 pixels.
