MATHBLAS.COM INSTALLATION

Math Blaster is

an educational game produced by

Davidson and

Associates in

Torrance Calif.

It works well with the

entire

Equity series except the Equity 1 running color mode.

The large

numbers

that

Math Blaster places on the

screen

are

done in

graphics

mode.

These numbers appear as square blocks of garble

on the Equity 1 color screen.

Unlike the GWBASIC used on the Equity

II and III,

GWBASIC for the Equity 1 does not

initialize

certain

memory

areas.

In particular,

area 510 of segment 0 is

not initialized (this area is used by BASIC to hold the default

data segment value).

Tests

have been run on ROM BIOS versions 2.1i, 2.20 and 2.21.

The

following

programs have proved to be an effective fix

for

cases tested so far:

HARDISK.BAS - For hard disk versions:

10 PRINT)" This patch will not work with config.sys files"

20 DEF SEG =0

30 POKE &H510,&HC9

40 POKE &H511,&H14

50 RUN "color

FLOPPY.BAS - For Floppy disk versions.

10 DEF SEG =0

20 PRINT "this is a fix for the floppy disk system"

30 PRINT "make sure no CONFIG.sys file is active"

40 PRINT "try this version on floppy systems"

50 POKE &H510,&HC3

60 POKE &H511,&H14

70 RUN "color

CONFIG.SYS and AUTOEXEC.BAT move things around in memory.

These

patch

programs will not work if either of these two programs are

activated on boot up.

Please copy the appropriate program

to the disk that contains your

Math Blaster program.

Run these programs and they will run the

Math Blaster program for you.
