That would be awesome.
Thanks, Ken.

Having found Cocoa Pom, I find it unusable on my machine. It can't keep up with my typing, and I can only type about 30-35 wpm. Jeesh! I'll just have to wait. Maybe in the meantime I should order an NVRAM chip, because I don't have my serial board set up, and I don't have a USB to serial converter e...

No way, it really helps. I've had so much C shoved down my throat it's hard to think in terms of a different syntax. Thanks for the pointers, and I'll keep a closer eye on my conditional branches. It would probably be easier to separate what happens on these conditional branches into subroutines.

Number Guessing Game

In the spirit of a little more fun (and re-creating a program I wrote for a TRS-80 when I was 9) here is a number guessing game. 100 REM ** NUMBER GUESSING DEMO IN APPLE I BASIC 110 REM ** BY CHRIS FORESMAN, 2006 120 DIM Y$(1) 130 PRINT "LET'S PLAY THE GUESSING GAME!" 140 PRINT &qu...

Bubble Sort program

Here is one of the programs I wrote for my project. Since I had trouble getting the machine to operate fully before I had to turn it in for grading, I couldn't test it out. Feel free to do so if you like, and let me know how it works. The actual sort algorithm is actually pretty short, and consists ...

That looks pretty sweet. Do you have a listing for the assembler? Maybe I'll get ambitious this summer while working at Whirlpool and make myself a new EEPROM. Looks like your assembler is really nice.

This project has been far more fun than any of the classes I've taken so far!

Actually, this wall wort was used in all my ECE experiments, including my digital logic design class. We regularly used it with PLAs and 74xx chips. I measured the output with a DMM and got a consistant 5.16V output. I know from some op-amp experiements that the output can be somewhat noisy, and we ...

Vince, I wonder if you were also able to enlarge the holes at the corners to work with standard PC mobo offsets, or if you know if something standard that works wit hte size holes that are on there. I ended up using tiny wooden spools as stand-offs and #4 woodscrews to attach the board to them. It's...

These may be dumb questions, but what the hell:

I looked at the schematic, and I'm not sure what pins 1 and 26 connect to. NC = no connection?

Also, I assume this is deisgned to work with the 40-pin expansion port, correct?

Thanks.

OK, I lied about the wall wort. After closer examination, it can output 800mA. Where I got 200mA I have no idea. <shrug>

But still, is not using a voltage regulator a big problem?

5V wall worts and such...javascript:emoticon(':?:')

I'm using a 5V 200mA wall wort, but I read somewhere that Vince recommends a 400-500mA one. Everything seems to work, but there is a problem that Vince attributed to bad RAM socket soldering or maybe a bad RAM chip. Would the would the 200mA max output be a problem? The wall wort is from my electric...

Here are my comments about the board: I don't see any holes for wiring in external clear and reset switches. Also, it looks like the USB port is far from the edge of the board, making it look difficult to have the ports flush with the case when you install it is one. And maybe it'd be nice to have s...

Could that home function be used for ASCII animation? Since it doesn't clear the screen?

I guess along with that I wonder what the columns and lines of the video display are. I remember using a similar feature to program a sort of Galaga-esc game on my TI-81 in high school.

Mmmmmm...ASCII.

My Apple I replica

Vince asked me to post some pictures of my Replica I. I just assmbled it for a History of Technology class project. I personally think its an A+! Since I'm only using a PS/2 keyboard, I wired an N-size DC power jack to a switch and then to the +5 and GND holes on the PCB near the top middle of the b...
