One runs into the limits of BASIC pretty quickly. In the world I was in back in those days (mostly 808x/Z-80/TRS-80/CP/M), people seemed to pretty quickly bifurcate from BASIC to either assembly or (usually Turbo) Pascal. I was in the later category, FWIW. Other than figuring out Z-80 asm well enough to cobble together custom CP/M BDOS and other components, I lived in Turbo Pascal. But then, it was dirt cheap. If it was more expensive (see: Pascal/MT), I might have been on a different path. KJ

I recommend reading MOS's original 6500 series programming manual. It's done in the form of a very well written tutorial. http://archive.6502.org/datasheets/synertek_programming_manual.pdf regards, Mike Willegal

OT: PHP HTTP POST setBasicAuth question.
by william degnan 17 Jan '17

17 Jan '17

Anyone here a PHP expert? I am banging my head against the desk here... I have the following code but for some reason it kind of seems like the username and password are not actually being sent. Does anyone here have the ability to receive an http post that I can send to confirm whether you're actually getting an attempted username and passowrd along with an XML document? Here is a code snippet working with: $r = new HTTP_Request($dest_url) or die("$dest_url: $php_errormsg"); $r->setMethod(HTTP_REQUEST_METHOD_POST); $r->addHeader('Content-Type', 'text/xml'); $r->setBasicAuth($username, $password); $r->addRawPostData($packet); $res = $r->sendRequest() or die("sendRequest:". $php_errormsg); I keep getting a 401 (Access Denied) error. No PHP errors. I can send debug output, etc. not posted here. This is a Windows PHP instance, PHP Version 5.4.31 Windows 2008 Server. Of course I am assuming I have the right username and password, but could there be logic error? I am posting to a major B2B portal, but it may be possible that multiple attempts have shut me down. I need to know if my code is correctly posting a username and password before I complain to them to fix their end. Thanks anyone.. Bill

time for me to learn assembly
by Evan Koblentz 17 Jan '17

17 Jan '17

Hey everyone. Trying to teach myself Apple II assembly. I have NO experience at this. All I ever learned was LOGO in elementary school and AppleSoft (Microsoft) BASIC in middle school. (I'm not counting a very small amount of LISP in college and mastery of HTML 4 which isn't programming.) Everyone said to get the book Assembly Lines. I got the PDF of the original version. Hit a glitch almost immediately. After doing CALL -151 to enter the monitor, it says to type F666G to enter the mini-assembler, and then "The prompt should change to an exclamation mark." It doesn't change to an exclamation mark. It just goes back to the asterisk. What's happening? Same behavior in LinApple (Linux Apple II emulator) as on my Platinum.

All this discussion inspired me to do a little with the PocketCHIP I got for Christmas. In addition to simh, I also got Inferno running on it and just for fun, here are a couple of pics of it running my ENIAC simulator. http://cs.drexel.edu/~bls96/eniac/chip1s.jpg http://cs.drexel.edu/~bls96/eniac/chip2s.jpg BLS

It's networked wirelessly, I can grab via CRON job the lpt.txt output file every 10 minutes to send "mail" from the simulator that way. > > Took 2 hours to MAKE them all. Posted more how to on my site ...so now I have three Pis and two CHIPS with simH installed.

Pocket CHIP simH
by william degnan 15 Jan '17

15 Jan '17

Anyone interested, I have been working on a standardized way to put simH on things, such as the Pocket CHIP. This is useful, you can make a serial connection to this or the Raspberry Pi and attach a termina on the other end. It's a safe way to demo ancient operating systems if your actual hardware is not quite ready for a full weekend of exhibiting, or you don't have peripherals. Obvious to many but some may find it useful to get into simH. Here is 101 on what I have been doing. My Linux skills are getting better, I use it daily now whereas a few years ago I was a lot more tentative with it. http://vintagecomputer.net/browse_thread.cfm?id=664
