HP E2411C and HP E5344A
Intel80486*
Preprocessor Interface
For use with
HP logic analyzers
The Hewlett-Packard E2411C
preprocessor supports the
Intel486DX, DX2, DX4, 486SX,
486SL Enhanced, and 487SX, as
well as the OverDrive for the
486DX chip. The preprocessor
interface provides an electrical
and mechanical connection
between your target system and
an HP logic analyzer.
Preprocessor software configures
the logic analyzer labeling
address, data, and status lines.
Additionally, when a state trace
is displayed, the data is
disassembled and listed in
80486 mnemonics. The disas-
sembler also decodes FPU
instructions for target systems
that use the Intel486DX and
Intel487SX chips.
