It's safe to say that IBM would not have distributed a COMPAQ binary; if IBM had distributed any BASIC binary at all,

And this disk has now been added to the PCjs [IBM PC Disk Library](/disks/pcx86/) as "Adventures in Math (1983)".
|
||||
|
||||
I originally selected an [IBM PC (Model 5150, 64Kb) with Color Display](/devices/pcx86/machine/5150/cga/64kb/),
|
||||
which boots PC-DOS 2.00 by default. However, in the course of starting the game, it would crash:
|
||||
|
||||
|
||||
|
||||
It appeared to run fine with 256Kb of RAM, but these were IBM's "System requirements" for the game:
|
||||
|
||||
> IBM Color Display, or a television
|
||||
|
||||
> 64Kb of memory for PC and PC XT, 128KB for PC*jr*
|
||||
|
||||
> One diskette drive
|
||||
|
||||
so I reconfigured the machine to boot PC-DOS 1.00, which required less RAM than PC-DOS 2.00, and that appeared to be
|
||||
sufficient. Note that the game was released in October 1983, well after the March 1983 release of PC-DOS 2.00, so
|
||||
either it wasn't tested with PC-DOS 2.00 on a 64Kb machine, or the error is a PCjs anomaly.
