CONVERT_INTEL is a utility program for converting INTEL Z80 ASCII files
to binary files ready for bootloading of LTU devices.
It is excecuted by the following command:
CONVERT_INTEL I:<INTEL input file> O:<boot file> [AMOS:NO]
The default option is AMOS:YES
The intel file consists of records (lines) of the following format:
: A colon as first character of the line
2 chars number of data bytes
4 chars load address of first databyte of record
2 chars record type (00=data , 01=end)
2 chars first data byte
2 chars for each additional databyte
2 chars checksum
the checksum is the negative of the sum of all the 8-bit bytes in the
record, including the one byte 'number of data bytes' and the two byte
'load address', with carries above 8 bits ignored.
E.g: The record
:0700D00001053609CBBEC992
. . . . -- checksum
. . . -- last of 7 data bytes
. . -- first of 7 data bytes
. ---- load address
-- count of data bytes
The checksum in above record is calculated as
0 - (#7+#0+#D0+#0+#01+#05+#36+#09+#CB+#BE+#C9) = #92
The generated binary file has the following format:
2 bytes start address
N bytes data as described by the INTEL file
1 byte checksum
The size of the generated file (N) is determioned by the address of the
last loaded databyte from the INTEL file, such that the generated file
always consist of an even number of bytes. The checksum is the last
byte of the file and is the sum of the N data bytes (mod #100).
The start address is always assumed to be zero.
Data bytes not loaded from the INTEL file is set to #76.
When the optional option 'AMOS:YES' is used the output file is preceded
by two words containing:
Module type: #0002
Word count: including these two words

>> 0102 <<
The DAMOS version had not been updated with the latest changes.
As it wasn't tested, this went unnoticed (for some time)!!!!!!
