    Well, my current job kinda requires I work when there's work, so it's difficult to get away, and the guys I work with have integrated me with their plans for a new company which could keep me very busy.
    If I go I'd probably drive and some of us could car pool.  There's at least 3 of us that would be along the same route.

    I wish you could make it...  I would love to meet up with you in person...



  2. BITD, ( 1982 ), I remember seeing the Model I, II, III and 4 at Radio-Shack and I faintly remember the Color Computer 1.   Since I was into the Apple ][, ( an Apple ][+, 48K at my High School and an Apple ][e at Home ), and a Commodore SX-64, because most of the rest of my family had the C64s.. In college, ( 1985 ),  I had a friend that Started with the Model I, and by the time I met him and his wife, they had moved up to the Model III and Model 4, and a Tandy 2000.  I go to borrow the Tandy 2000 for a month, but is was only MS-DOS compatible, so unless I wanted to write all my own Software, there wasn't much to run..


    Today, i'm into the Tandy Color Computer, because in 2012 I got a NIB, Color Computer 3, ( CoCo 3 ), that was included with an Apple //e Platinum with Apple Color Monitor ][e and some original software.  At first I wasn't quite sure what to do with it, but found it has the MC6809, which is very much like the 6502 family, and since I never had any Color Computer equipment before, so I kept it...

    Since then, I have gotten, Two of the CoCoSDCs, Two FD-500 Drives, a Extended Basic 64K CoCo 2, and then a Standard BASIC 16K CoCo 2, with a BONUS, ( reported Non-Working ), 4K CoCo 1.. By the time it arrived, the CoCo 1 worked fine... Three more CoCo2s and another CoCo 3 and a few CoCo Carts.

    See my specific thread on that subject:


    Very Interesting...


    I was at my "local" Apple Dealer, "Team Electronics" pretty frequently..  I would guess that it wasn't in their, ( best ) interest to offer the Apple ][ / ][+ / ][e as a kit, since this wasn't offered as an option..


    Possibly a more "hobbies oriented" place, like The Byte Shop would have different clientele and offer different services.


    I think I would have liked growing up in the Silicon Valley in the 1970s..    Alas, at least I benefited from growing up near the Silicon Forrest..

    No, there is no such support for initializing variables. Frankly I had never seen it before C++ and alike, does even regular C support it? I don't think Pascal does either. The FOR loop + DATA statement possibly is the best tradeoff for speed vs code size.


    If you hack BASIC, there might be a way to point a variable to a defined set of data elsewhere in memory but I don't know how well that would work, since each number appears to be stored in floating point format once the interpreter has assigned it.


    Yes, even the original 'C' supports Loading the Arrays when they come into Scope.. 

    here are some code examples from the ANSI Edition of the 'C' White Book:

      static char daytab[2][13] = {       {0, 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31},       {0, 31, 29, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31}   };
     static char *name[] = {       "Illegal month",       "January", "February", "March",       "April", "May", "June",       "July", "August", "September",       "October", "November", "December"  };

    Excellent!  I saw "pick up only" and was thinking I had to go on a drive.  That machine needs some love.


    Show 'n tell when you get it done please.



    I have made a bit of, Head Way, but I’m getting married next month, and I am packing everything up to move to a new ( slightly bigger ) place..  So the Northstar is hibernating for now...


    i did post post a bit on the VCFed forum, in the S100 bus section...


    i will I’ll post pictures and results here soon..



  6. My "first" Computer Experience was the Apple ][+, in JAN-1982 at my High School.  A year later, my Dad and Uncle bought Sinclair ZX-81 Kits, and in NOV-1983, I became a Half-Owner of an Apple ][e.

    My start with Personal Computers, especially the Apple ][+ is an interesting story, in that I discovered them because I was perpetually late to my First Period Class, Chemistry...

    My Chemistry Teacher "assigned" me to After School Detention, which started at 15:30, and school ended at 15:10, so while waiting for Detention to Start, the Business classroom next door had Three, Apple ][+s.
    One with Two Disk ][s, and an Epson MX Printer, One with One Disk ][ and a Hammer type printer and One with just a Disk ][.
    All had 48K RAM and the Language Card with Integer BASIC.

    The Business Instructor let me read the AppleSoft Manuals, the Disk ][ Manuals and the Epson Printer Manuals..

    This Introduction to Personal Computers lead to getting the Sinclair, and then the Apple ][e, and later a Commodore SX-64 and then IBM-PC Clones and eventually the Tandy Color Computers. ( and an Osborn I and just a few weeks ago, a Northstar Horizon )


    I also went to the local community college and learned some Electronics, and Computer Programming, including COBOL and eventually into Embedded Programming.



    My favorite Apple ][ games are Castle Wolfenstein, Load Runner, and the Adventure Games like EAMON and Odyssey, The Complete Apventure, and the Infocom Games.

    I found one on the Color Computer Archive, but I was hoping for something bigger.

    Hi!!  Long Time no Speak....   :) 
    Are you making this an RS-DOS HD Image or NitrOS9/OS9 Image???   128 MB seems to be the largest practical Disk.

    The ToolShed Utilities work really good for these sorts of things...

    I have had an Apple IIGS for many years. Today, I put in the startup disk  (5-1/2 in floppy) and got the message "unable to load prodos".

    I proceeded to put in another startup disk and it loaded and asked for the program disk. When I put that in and hit enter it said "the date must be 1983 or later, and in this format 3/20/83. At the bottom it said type today's date or press return: 3/20/84 - I pressed enter and at the top of the next screen was a bunch of number and letters that make no sence at all.  ANY SUGGESTIONS?  Really appreciate any help I can get.

    Could be looking at Bad RAM..  Can you run the Self Test??
