I've been looking for this very simple program for the PET (I'm assuming I could also use the 64 version, and convert it to the right memory location with unicopy). I recall that it came with my 64 originally. I'm having great difficulty finding it on the web. Does anyone have it (e-mail me a ZIP file) or point me in the right direction?


Thanks!

I can't believe how incredibly difficult this little BASIC game was to find (it took about 3.5 hours in total). When I owned my first C64, this program was everywhere! I believe it came on the "Commodore Program Pack", which was given away in Canada as a promotional item upon the purchase of a new C64 system (computer + disk drive) in 1983.

If you want to download it for yourself, find a .T64 image here: http://www.myabandonware.com/game/lemonade-4eu

I remember playing this in high school. We figured out how to cheat with the change of one command.
 
As previously stated, I found the C64 version - it works great - on the 64.....but I remember there being a PET version (can anyone verify that?). The 64 version will not load into the PET. Could it be because it's in a different memory location?

Does anyone know where I can get the PET version?
 
If it's a BASIC program and does not contain any PEEK or POKE statements, it's very simple to run on the PET. You much change the load address, as BASIC programs reside in a different memory location on the PET vs the C64.

Fallo said:
The problem with BASIC files is the following: The PET's BASIC RAM starts at $0401 -- and that's also what the first two bytes of a PET BASIC PRG file should state. When loading such a BASIC program into a C64, it gets nevertheless loaded to $0801 (the C64's BASIC RAM) and automatically re-linked so that all "next line" pointers point to the appropriate addresses. The PET, however, seems incapable of relocating BASIC programs so that a program thus saved to tape does get loaded to $0401, but its "next line" pointers keep pointing to their C64-based $08something targets.

To load C64 BASIC files on the PET, do the following:

Type 0 REM

Load the BASIC file

Type SYS 1024 to get into the PET's monitor

Type M 0400-0410 to dump the first few bytes of BASIC memory. You should see an 01 04. Change this to 01 08 and exit the monitor. When you type LIST, you'll now see your BASIC program. The 0 REM line will be at the top of it; just type 0 and hit Return to get rid of it.

Once you've done that, make sure to save the program; and save it on a proper disk formatted in the drive you use on your PET.
 
Given that it has no graphics or sound, it should be easy to port to just about any 80s micro running BASIC. You'd think with its superior graphics and sound, the C64 version of Lemonade Stand would be better than the Apple II version :p
 
Thanks. I'll try that. The 64 version has poke commands, but I believe they're primarily for colour.

Ok, then delete them, else nothing will happen, or something bad will happen. Best would be to look up the addresses and see what they are. Some may be for plotting directly to the text screen, or cursor control, or other such things that work on the PET but may have different locations.
 
Is there a DOS port for this?

Lemonade Stand is a business simulation game created in 1973 by Bob Jamison of the Minnesota Educational Computing Consortium (MECC). In it, the player moves through several rounds of running a lemonade stand, beginning each round by making choices dependent on their current amount of money about their stock, prices, and advertising. In each round, the results are randomized based on the player's inputs, as well as affected by random events such as thunderstorms and street closures. Each round ends with a summary of the player's current status, and the game ends after 12 rounds.

In 1979, the game was ported by Charlie Kellner to the Apple II; Apple subsequently included the game with their computers throughout the 1980s. MECC also offered the game for sale as a part of bundles of children's software for Apple computers and Atari 8-bit computers. Kellner's source code was released, and has since been ported to modern computers as a free, open-source game. Reviewers of the game, both contemporary and retroactive, viewed the game as a good primer for children into business and decision making processes.


There are similar flash-based simulations on the web:

Last year I was looking for the original PET version as well - it is very hard to find that true, original version. Most versions for the PET computer available on-line are back-ported from the C64 version.
After a long search, I was able to find it.

Here is the thread where I searched for it and eventually found it:
http://sleepingelephant.com/ipw-web/bulletin/bb/viewtopic.php?t=7841

To summarize:

It's on the Toronto PET User's library CD-ROM, in a disk image labelled "(o)e9.d64", which you can buy here:
http://www.ebay.com/itm/TPUG-Library-CD-for-Commodore-64-PET-VIC-20-and-Amiga-/302015100759?hash=item465180b757:g:eHoAAOSwUuFWxeXc

I would recommend buying this disk. It's great value for the money and will give you hundreds (thousands?) of pieces of obscure pieces software for all of your Commodore machines - much of it is not available online elsewhere (that I have found).

NOTE: One message in that Denial Thread provides a download link to a "converted" PET lemonade stand binary, but be aware that is also a back-port from the C64 version, not the original version (I don't know how much you care about that).

Here is TRUE, original PET version of Lemonade Stand from (o)e9.d64:

Thanks so much! I should really invest in the CD with all of the TPUG disks. I have some of the original floppies from years ago, but not that particular one. I appreciate you uploading the original version for me (and others) to enjoy!
