Signetics Absolute Object Format, Code 85

Figure D-12 shows the specifications of Signetics format files. The data in

each record are sandwiched between a 9-character prefix and a

2-character suffix.

The start character is a colon. This is followed by the address, the byte

count, and a 2-digit address check. The address check is calculated by

exclusive ORing every byte with the previous one, then rotating left one

bit. Data is represented by pairs of hexadecimal characters. The byte

count must equal the number of data bytes in the record. The suffix is a

2-character data check, calculated using the same operations described

for the address check.

The end-of-file record consists of the colon start character, the address,

and the byte count (equal to 00).

Tektronix Hexadecimal Format, Code 86

Figure D-13 illustrates a valid Tektronix data file. The data in each record

are sandwiched between the start character (a slash) and a 2-character

checksum. Following the start character, the next 4 characters of the

prefix express the address of the first data byte. The address is followed

by a byte count, which represents the number of data bytes in the record,

and by a checksum of the address and byte count. Data bytes follow,

represented by pairs of hexadecimal characters. Succeeding the data

bytes is their checksum, an 8-bit sum, modulo 256, of the 4-bit

hexadecimal values of the digits making up the data bytes. All records

are followed by a carriage return.

Data are output from the programmer starting at the first RAM address

and continuing until the number of bytes in the specified block has been

transmitted. The programmer divides output data into records prefaced

by a start character and an address field for the first byte in the record.

The end-of-file record consists of a start character (slash), followed by the

transfer address, the byte count (equal to 00), and the checksum of the

transfer address and byte count.

An optional abort record contains 2 start characters (slashes), followed by

an arbitrary string of ASCII characters. Any characters between a carriage

return and a / are ignored.

Motorola EXORmacs Format, Code 87

Motorola data files may begin with an optional sign-on record, initiated

by the start characters S0. Data records start with an 8- or 10-character

prefix and end with a 2-character suffix. Figure D-14 shows a series of

Motorola EXORmacs data records.

Each data record begins with the start characters S1 or S2: S1 if the

following address field has 4 characters, S2 if it has 6 characters. 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 (6 characters for addresses above hexadecimal FFFF). Data

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

of data bytes occurring must be 3 or 4 less than the byte count. The suffix

is a 2-character checksum, the one’s complement (in binary) of the

preceding bytes in the record, including the byte count, address, and data

bytes.

The end-of-file record begins with an S9 start character. Following the

start characters are the byte count, the address, and a checksum. The

maximum record length is 250 data bytes.
