HOW TO STARTUP
The computer itself consists of many electronic parts such as LSIs
and ICs, and other electrical and mechanical parts. These are called
"hardware".
The computer can perform various kinds of jobs using programs that
determine the sequence the computer should follow to do the job.
(These programs are also called "software".)
For the HB-501P, there are mainly four types of program:
• Program built in the HB-501P
Personal Data Bank
MSX-BASIC interpreter
• Program stored in the cassette supplied with the HB-501P
Personal data bank
• Commercially available programs in MSX-cartridge form
Games and other useful programs are available.
• User designed programs in MSX-BASIC
You can make your own programs using the built-in MSX-BASIC
interpreter. A knowledge of BASIC programming is required.
When all the necessary connections have been made, select the
program and follow the appropriate steps to get started.
TO START UP THE PERSONAL DATA BANK
Insert the supplied cassette tape into the bit-corder and make
necessary adjustments for loading.
For details, refer to "How to use the Personal Data Bank".
Data created by the Personal Data Bank can be saved to a cassette
using the built-in bit-corder, to an optional HBI-55 data cartridge or
to a microfloppy disk using the HBD-50 micro floppydisk unit.
To use the data cartridge or micro floppydisk unit, first insert the
data cartridge or the interface cartridge of the micro floppydisk unit
into the cartridge slot LU or [

], then turn on the power.
Refer to "How to use the Personal Data Bank" for details.
Note on MSX-DOS
When MSX-DOS commands (except DIR, FORMAT and BASIC) are
used, data created by the Personal Data Bank are not maintained.
Therefore, be sure to save data before transferring control from the
Personal Data Bank to MSX-DOS.
Once the above MSX-DOS commands are used, the following MSX-
BASIC commands cannot be used:
SAVE "CAT:", LOAD "CAT:", CALL HITBIT
TO START UP MSX-BASIC
1 Turn on the monitor TV and the computer.
The computer enters the MSX-BASIC command wait state.
For further operation, refer to "Introduction to MSX-BASIC" and
"MSX-BASIC Programming Reference Manual".
