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.MarkO -

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..

Apple Computer offered the Apple ][ in 1977 as a Motherboard Only or as a completed system.. The Motherboard Only wasn't offered for very long, from what I have learned, so for the Most Part, the Apple ][ was a Home Computer...
All the slots did mean that you could add on to it......

"Apple Roots: Assembly Language Programming for the Apple //e and //c" by Mark Andrews is also on BombJack.org, in the Apple ][ Section.

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" }; -
Didn't the Copy ][ Utilities has this feature??

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..

In case You All didn’t, “read between the lines”, I now have this Northstar Horizon, and have started the path to Refurbishment..
But, I have set it aside for a few weeks as I pack up and move houses...

Doing a search at https://www.archive.org/ didn't return any results for the Title. Do you have a Link to it??

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 can get to the Discord Serve, it just never remembers me.. This is the First Discord Link that works this way.

Did Byteboosters clarify why the ][+ doesn't work, but the ][e Does..

The "First Software" I recall buying, was The Merlin Assembler, ( DOS 3.3. & ProDOS ), for the Apple ][e, and "Assemble Lines", from SoftTalk Publishing..

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...MarkO

Sounds like a Keyboard Issue...
If you unplug the Keyboard from the Motherboard, and Power Up the Apple, the computer should jump directly into the System Test....Has anyone here tried something like, De-Oxit on the Keys???

The Tandy Color Computer still have a Club, and they have Monthly meetings and a Once a Year, get together, usually in April, but not this year...
I also participate in a Weekly Live Stream, for the Tandy Color Computer, called CoCoTALK! It's kind of like a User Group Meeting, with a World Wide audience..

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

Pretty Nice...
Back in the 1980's, of the 8-10 BBSs in the Salem, Oregon area, only one was 300/1200.. It was run on a NorthStar Advantage...

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