SuperBrain II Users Manual SuperBrain II Software Summary SECONDARY CHARACTER SET OPTION
As was stated in the theory of operation section, the SuperBrain II provides a means by which a secondary character set option may be added. This gives the user the ability, via the software, to select either set. Intertec will provide a limited number of these alternate character sets, or if required, the customer may create a character set using software that is supplied by Intertec. In the following sections, both of these methods will be explained.
INTERTEC FURNISHED SECONDARY CHARACTER SETS
The easiest and quickest way to have access to a secondary character set would be to purchase one of the sets available from Intertec. This character set would be contained on an EPROM that would be inserted into a vacant IC socket on the processor board. After the EPROM has been inserted into its socket, it can be initialized via the escape sequence given in the attribute program section. Secondary character set installation procedures will be provided with each set purchased from Intertec.
CUSTOMER CREATED SECONDARY CHARACTER SETS
For those requirements where Intertec does not offer a suitable secondary character set, one can be created by the user. The CP/M disk provided with the SuperBrain II contains two utility programs that provide the means for creating and verifying secondary character sets. These two programs are CSEDIT.COM and CSDUMP.COM.
CSEDIT.COM
The CSEDIT utility provides the means for creating a secondary character set. The program is loaded from the disk by typing CSEDIT and then pressing RETURN. The initial screen message will read:
SuperBrain II Character Set Editor - Ver 1.X Enter the character sst file name:
The new character set file name should then be entered in the normal format of filename.typ and then pressing RETURN. The next screen message will read:
Enter hex value of character to edit (0-7F, eXit, Quit, or ?)
As indicated by the parenthesis, there are four options (0-7F, eXit, Quit, or ?) available at this point. Since the
"?"
is the help page and will explain the other 3 entries, type ? and press RETURN. The following page will appear on the screen:The input required at this point is the hex value of the ASCII character that you wish to edit. This value must be in the range of 00 to 7F hex. You may also enter a "X" to exit the program and update the character set file, or a "Q" to abort the program and not update the character set file.

SECONDARY CHARACTER SET OPTION (continued) All cursor keys on the keypad work as would be expected.
Hit RETURN to continue:
After reading the help page, pressing RETURN will cause the initial screen message of the program to reappear. At this time the user should be ready to start the process to create an alternate character set. The following examples are from the standard character set provided with the SuperBrain II.
"1" - Invert pattern dots
Editing Number -41 H
"0" - Clear dot at current position ENT - Go to start of next line
"3" - Recall previously saved pattern ESC - End editing of character
"2" - Save pattern in temp. buffer
"7" - Clear character cell
BRK - Abort with no change to pattern
"." - Put dot at current position
"_" - Clear current line
"1" Invert pattern dots
Editing Number - 65H
"0" - Clear dot at current position ENT - Go to start of next line
"2" - Save pattern in temp. buffer
"3" Recall previously saved pattern "7" - Clear character cell
ESC End editing of character BRK - Abort with no change to pattern

BRK - Abort with no change to pattern After all the secondary characters have been created, by typing "X" and pressing RETURN, the new character set will be written on the disk as a binary file and the verification process can accomplished, type CSDUMP, and press the RETURN key. The following message will appear on the screen.
SuperBrain II Character Set Dump - Ver 1.X Enter character set file name:
Enter the file name and press the RETURN key. The character set will be dumped out to the printer and the resulting page set should look similar to the one shown on the Sample Page -Character Set Dump exhibit.
The character file generated by this procedure can then be transferred to an EPROM programming machine using the HEXDUMP.COM utility. Once the EPROM has been created, it should then be inserted into the empty IC socket Z75, as indicated in the Socket Z75 exhibit. The initialization of the new character set is contained in the Escape Sequence covered in the Attribute section of this manual.
The part numbers for the blank EPROM are, Intertec part number 30122516 or Texas Instruments part number TMS-2516JL-35 or equivalent.
Any questions concerning Intertec created secondary character sets or the procedures or materials necessary to create secondary character sets should be referred to the Customer Services Department at Intertec Data Systems Corporate Headquarters.
