Backpack Emulator
INTRODUCTION
The Rockwell R6S00/1 EB and R6S00/1 EAB Backpack Emulator
is the PROM prototyping version of the 8-bit, masked-ROM
R6S00/1 one-chip microcomputer. Like the R6S00/1, the back-
pack device is totally upward/downward compatible with all
members of the R6S00/1 family. It is designed to accept stan-
dard S-volt, 24-pin EPROMs or ROMs directly, in a socket on
top of the Emulator. This packaging concept allows a standard
EPROM to be easily removed, reprogrammed, then reinserted
as often as desired.
The backpack devices have the same pinouts as the masked-
ROM R6500/1 microcomputer. These 40 pins are functionally and
operationally identical to the pins on the R6S00/1, with some
minor differences (described herein). The R6S00/1 Microcom-
puter Product Description (Order No. 212) includes a descrip-
tion of the interface signals and their functions. Whereas the
masked-ROM R6S00/1 provides 2K bytes of read-only memory,
the R6S00/1EB will address 3K bytes of external program
memory. This extra memory accommodates program patches,
test programs or optional programs during breadboard and proto-
type development states.

R6500-1EAB
R650011 EB and R6500/1 EAB
CONFIGURATION
The external memory must always occupy the upper 2K of
available memory (addresses 800 through FFF) for implemen-
tation of interrupt vectors. See Memory Map. The Backpack
Emulator provides a read block to the external memory where
internal RAM or 110 are located in the same addresses as that
occupied by external memory.
EXTERNAL FREQUENCY REFERENCE
The external frequency reference may be a crystal or a clock.
The R6500/1 EB and R6500/1 EAB divide the input clock by two
regardless of the source.
Backpack Emulator
1/0 PORT PULWPS
The emulator devices have internal I/O port pullup resistors.
PRODUCT SUPPORT
The Backpack Emulator is just one of the products that Rockwell
offers to facilitate system and program development for the
R6500/1.
The Low Cost Emulator (LCE) with R6500/1 Personality Module
supports both hardware and software development. Complete
in-circuit user emulation with the R6500/1 Personality Module
allows total system test and evaluation. With the optional PROM
Programmer, the LCE can also be used to program EPROMs
for the development activity. When PROM programs have been
finalized, the PROM device can be sent to Rockwell for mask-
ing into the 2K ROM of the R6500/1.
