VERY MINOR ERRATA: Because there are NEW OSCILLOSCOPES in the lab as of Fall 2008, there are some slight changes to Step 13 of Lab Exercises, where you get briefly acquainted with the instrument to be used more extensively in Lab 3: 1) The "Calibration Input" is now called the "Probe Comp" input, and has a ground connection immediately above it (lower right of scope). Actually, it was always called the "Probe Comp" input, so this just fixes a long-standing error. 2) The factory default state is reached by pressing only one button, labeled "Default Setup." There is no need to press a "SAVE/RECALL" button first, nor is there a need to confirm your action. 3) In the last part of Step 13, you'll use a USB stick instead of a floppy disk. And to produce a better, more readable output, before saving the screen, press the "Menu" button (under Save/Recall, below the screen), then select "Save Screen Image ," and finally turn the Ink Saver option "On." This prints black on white, which keeps your narrow waveform and grid lines from being lost in the toner. 4) And finally, in that last step, press "OK - Save Screen Image " instead of "Hardcopy" to actually save your waveform. For subsequent saves, you can use the "Save" button without going through the menus, as long as you have NOT changed the assignment of the "Save" button. (Someone may have changed it to something other than "Save Image," which would give you the wrong data. That can be restored in the same menu where you set the Ink Saver feature.) Don't forget to take your memory stick with you!

Protoboard Tutorial This vintage video from one of your textbook authors (Mike Furman), is as applicable today as it was ten years ago. WATCH IT. There is a reference to a particular section (section 5) of a Motorola TTL data book -- you'll probably not find that particular data book anywhere, but see the references below...

Keep your protoboard NEAT. Consider this an example of what you need to produce for full credit. This implements a particular state machine, but the techniques apply to any circuit. Note that wires should not cross over chips, so you can unplug chips to check them. wires should be no longer than necessary, so that they stay flush with the protoboard surface wires that enter/exit the protoboard should be generally on the edge of the board where they would go to the CADET To better understand the specifics of connection paths, including power bussing, see the highlighted detail of three particular signals.

Datasheets for different families (LS, AS, HCT, etc.) of TTL parts can be found at the following web sites, and perhaps others.  Different TTL-compatible logic families may be used, but you must be careful to not accidentally read values for the WRONG series, some of which may appear in the SAME datasheet.  Watch the column headings and page headings! This becomes more important with timing parameters in Lab 3. Use this site if at all possible! www.ti.com (Select "logic" product family and use navigation tools to narrow descriptions to NAND gates.  Once you have information on the correct part, look for the "datasheet" download.) Do not use this, unless the above site is down or something... www.onsemi.com (LS parts do not show up in their current product offerings, but a search for a particular part will find the datasheets.) No matter how much a TA or anyone else recommends alternate datasheets, be aware of these things: All parts of a given type (e.g., all "LS00" parts) have the same spec, regardless of the manufacturer. If you come up with different numbers than shown on a Texas Instruments datasheet, you have the wrong numbers. Not all manufacturers make really good datasheets, and students often read them wrong You're responsible for finding the only CORRECT answers, and you cannot blame the person who gave you another source than those listed above.
