The BD52 is an 8032 based single board computer that I developed and
marketed in the mid 1990s. This was shipped as a complete development package
which included:Selling price was $200 US.
The BD52 board contains the following hardware:
Library functions were included with the C compiler to provide access
to all programmable devices.
- 8032 microcontroller
- 64K of static RAM
- 32K of ROM (EPROM)
- RS-232 serial port
- 2K I2C EEPROM
- 7-channel relay driver
- 4-channel analog to digital convertor.
- Watchdog and power-monitor
- Regulated power supply.
- Buss expansion connector.
- Programmable Logic Array with configuration jumpers to accomodate many
different configuration options, and to provide hardware support for debug
features not normally available on the 805x family processors.
With the included software, the BD52 could be run in several modes:
- Normal operation with code in EPROM
- Code downloaded into RAM on the board, the PAL provided a means of
mapping RAM to CODE memory and downloading to it (not normally supported on
the 805x family). This allowed full debugging, including the ability to
breakpoint and patch code.
- Simulation on the PC with I/O occuring on the board.
Quite a few BD52s were sold and it received good reviews, however the cost
of manufacturing in Canada and problems/costs in shipping to the U.S. eventually
resulted in the decision to discontinue the product.
