Can anyone help me remember an Apple //e disk that would load to a command prompt, then you would type:
] RUN A1
It would then load a list of programs/games, where you could hit a number to load the corresponding program.
It could've just been a generic loader (maybe a popular one?), or maybe I even programmed it myself, in which case you won't remember it
Should be a snap to write something like that in BASIC.
I don't currently have access to my Apple disks, but I have a few different 'HELLO' programs that list what is on the disk and lets you load and run by various means (select by number, by cursor, etc...). I won't be back for 4 weeks, so I hope someone can help out.
Thanks, that sounds like the sort of thing. I'm just interested to see if anyone remembers the actual "A1" program from yesteryear
Yeah... I think that was a fairly common boot loader with some hacked games in the 80's... let me look
Check this out... sorry about formatting... but you can have it all together in a few minutes!

I found it on the Choplifter disk... I hope its what your after!
Thanks a lot! Now excuse my oldie newbieness, but this is all very foggy to me.
I have ADTPro. What's the best/easiest way to get this back onto the //e, other than typing it in manually? If it's on Choplifter, presumably I could just copy that .dsk file to a blank floppy via serial? If so a link to the version of Choplifter you found with the loader on it would be most appreciated!
I wish I could remember what games were actually on the disks I used that loader with. I know Choplifter was one now If anyone finds any others please post here
Here is an improved line 62640:
62640 C1 = INT (CV / 8):C2 = CV - C1 * 8:P = 1024 + 128 * C2 + 40 * C1 + CH:C = PEEK (P): RETURN

From now on, let's just use the shorthand "it's on Asimov" and you'll know what we mean. It will be important for most any question starting with "do you know where I can find..."
If seeking for that kind of hello program
( and that is not limited to the disk of choplifter )
you´d be better by searching for the Utility City Disk from Beagle Brothers at:
http://beagle.applearchives.com/the_software/vintage_beagle_bros_softwar/utility_city.html#previous-photo
and after extraction of the zip-disk to diskimage on the disk the File "Key Cat"
look at description file for explenation
they published similar variations of hello programs.....
like the enhanced version from "Tip Disk 1"
so i´d recommend also to read the manuals / descriptions of the disks also availiable at that site....

That line modification was from me... the first time I posted it, it turned part of it into a smiley face... and the formatting was screwed up. I didn't know how to change it so I changed the line, fixed the formatting and reposted it... glad it worked for you!
Thanks David for the file. And yes, shorthand agreed.
Very interesting, thank you!
So, having played with Choplifter, and Utility City, they're certainly the "type" of program I was looking for, but I'm going to refine my original request. I'd really love to track down the actual disk image I was using back then, where you had to type RUN A1, as opposed to RUN KEY-CAT or RUN HELLO, etc.
I realize it's a long shot, but if anyone has any recollection, this is the place to say so!
