Fairchild Fairbug, Code 80

In the Fairbug format, input and output requirements are identical; both

have 8-byte records and identical control characters. Figure B-8 shows a

Fairbug data file. A file begins with a 5-character prefix and ends with a

1-character suffix. The start-of-file character is an S, followed by the

address of the first data byte. Each data byte is represented by 2

hexadecimal characters. The programmer will ignore all characters

received prior to the first S.

Note: Address specification is optional in this format; a record with no address

directly follows the previous record.

Each data record begins with an X and always contains 8 data bytes. A

1-digit hexadecimal checksum follows the data in each data record. The

checksum represents, in hexadecimal notation, the sum of the binary

equivalents of the 16 digits in the record; the half carry from the fourth bit

is ignored.

The programmer ignores any character (except for address characters and

the asterisk character, which terminates the data transfer) between a

checksum and the start character of the next data record. This space can

be used for comments.

The last record consists of an asterisk only, which indicates the end

of file.

MOS Technology Format, Code 81

The data in each record are sandwiched between a 7-character prefix and

a 4-character suffix. The number of data bytes in each record must be

indicated by the byte count in the prefix. The input file can be divided

into records of various lengths.

Figure B-9 shows a series of valid data records. Each data record begins

with a semicolon. The programmer will ignore all characters received

prior to the first semicolon. All other characters in a valid record must be

valid hexadecimal digits (0-9 and A-F). A 2-digit byte count follows the

start character. The byte count, expressed in hexadecimal digits, must

equal the number of data bytes in the record. The byte count is greater

than zero in the data records, and equals zero (00) in the end-of-file

record. The next 4 digits make up the address of the first data byte in the

record. Data bytes follow, each represented by 2 hexadecimal digits. The

end-of-file record consists of the semicolon start character, followed by a

00 byte count, the record count, and a checksum.

The checksum, which follows each data record, is a 2-byte binary

summation of the preceding bytes in the record (including the address

and byte count), in hexadecimal notation.

Motorola EXORciser Format, Code 82

Motorola EXORciser data files may begin with an optional sign-on

record, which is initiated by the start characters S0. Valid data records

start with an 8-character prefix and end with a 2-character suffix.

Figure B-10 shows a series of valid Motorola data records.

Each data record begins with the start characters S1. The third and fourth

characters represent the byte count, which expresses the number of data,

address, and checksum bytes in the record. The address of the first data

byte in the record is expressed by the last 4 characters of the prefix. Data

bytes follow, each represented by 2 hexadecimal characters. The number

of data bytes occurring must be three less than the byte count. The suffix

is a 2-character checksum, which equals the one's complement of the

binary summation of the byte count, address, and data bytes.

The end-of-file record consists of the start characters S9, the byte count,

the address (in hex), and a checksum. The maximum record length is 250

data bytes.
