Intel Intellec 8/MDS Format, Code 83
Intel data records begin with a 9-character prefix and end with a
2-character suffix. The byte count must equal the number of data bytes in
the record.
Figure D-11 simulates a series of valid data records. Each record begins
with a colon, which is followed by a 2-character byte count. The 4 digits
following the byte count give the address of the first data byte. Each data
byte is represented by 2 hexadecimal digits; the number of data bytes in
each record must equal the byte count. Following the data bytes of each
record is the checksum, the two’s complement (in binary) of the
preceding bytes (including the byte count, address, record type, and data
bytes), expressed in hex.
The end-of-file record consists of the colon start character, the byte count
(equal to 00), the address, the record type (equal to 01), and the checksum
of the record.

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.
