GUSTEST.EXE v1.21 4/6/1993
GUSTEST is a simple program which detects the base address of the
Ultrasound and how much memory is installed. (For some reason on
my system DRAM lies and says I have 768K. And no, I'm not running
SBOS at the time.)
If you specify the -t option, GUSTEST will write patterns to check the
DRAM installed on the GUS.
If you specify the -u option, GUSTEST will assume you're using unsigned data.
If you specify the -s option, GUSTEST will assume you're using signed data.
If you specify the -w option, GUSTEST will swap data bytes for 16-bit samples.
If you pass filenames to GUSTEST, it will play them as .SAM files.
If you specify the -d option, GUSTEST will dump the DRAM contents to screen.
The -b option lets you choose 8-bit (-b8; default) or 16-bit (-b16) SAMs.
The -z option clears the DRAM.
This is my first GUS program so far... apologies if you think it sucks.
Written using Turbo C++ v1.01 in C mode.

A tiny fix (< instead of <=) was made to prevent 1024K GUS owners from
being told they have an extra 256K. (4/5/93)
The block-move and block-set routines were speeded up considerably.
I can now clear 256K of DRAM to zero in 3.3 seconds, including program
loading from disk/cache. Also includes source, with C (and C++?) code
for using the GUS. No assembler required... it's all in Turbo/Borland
C. Enjoy! (4/18/93)
