yipee!!!! My card works. I tried your program, Grant. Here are the octal codes for it (assuming you start it at 000):
000 076 001 003 002 323 003 020 004 076 005 025 006 323 007 020 010 333 011 020 012 346 013 001 014 312 015 010 016 000 017 333 020 021 021 323 022 021 023 303 024 010 025 000 I have not tried your program yet, Marty. I'll give that a go tomorrow. Thanks, guys! Paul |

Now, even though you were basically doing what a robot could do...building the board...doesn't it just give you a great feeling of accomplishment!?
When that thing is booting basic using your several thousand solder joints all the pain and suffering will have been worth it. ![]() ![]() ![]() |

Paul, what kinds of other programs have you made? What resources did you used to do it? Any tips and hints for other people in your situation?

All that was pretty boring and I don't really have any tips to offer. I made lots of mistakes in loading the programs through the switches. I played around with the am radio program and made a few different tunes, including the first half of Happy Birthday. I would recommend anyone who has a musical ear try that one. I would key in the song data, run the program, hear any notes that were not right, and quickly fix just the relevant notes until the pitch was correct. Musical trial and error. Perhaps now that I understand how to input data from the serial IO card I will try to capture the keystrokes that come in and store them in memory somewhere to create the tone sequences for songs instead of manually loading successive memory locations with the relevant values. It is probably even straightforward enough to make the altair play tones as I press keys and I might try that as well. These are just some ideas to get some fun out of the work done so far. Nothing earthshattering, just basics. Paul |

Hi Paul;
There is a musical program from Dr. Dobbs, that I have at home, which works from the sense switches, I'll try to get it for you the next time i'm home. and here is the origional program from computer notes, I think it has some ERRORS in it, but it should point you in the right direction. Also I know there are some articles about the 88-sio and the 88-2sio, somewhere in the 'computer notes' ,, I just didn't have time to locate them last night. This came from 'computer notes vol 1, issue 6. 000 333 001 000 002 017 003 332 004 000 005 000 006 333 007 001 010 062 011 040, this can be anywhere you want in memory 012 000 013 333 014 000 015 007 016 332 017 012, I think this should be 013 020 000 021 072 022 040 , this can be anywhere you want in memory 023 000 024 323 025 001 026 303 027 000 030 000 There were some other programs in this article that I didn't copy. Have a good time, Thanks Marty ![]() |
