Ampro Computers CoreModule/XTPlus
The CoreModule/XTPlus offers a high performance PC compatible subsystem in a compact, preconfigured module. Within just 14 square inches of space, the CoreModule/XTPlus includes the equivalent functions of a PC motherboard plus several additional expansion cards.
Specifications
PC Motherboard Functions
- 16-bit NEC V51 CPU, 16 MHz (V30 core, 8086 superset)
- System DRAM:
- 2M bytes onboard DRAM
- LIM 4.0 compatible EMS memory management
- System DRAM:
- 3 DMA channels (8237 equivalent)
- 8 interrupt channels (8259 equivalent)
- 3 programmable counter/timers (8254 equivalent)
- PC-compatible keyboard port
- Speaker port with 0.1 watt drive
- 8-bit PC/104 expansion bus
- Award ROM-BIOS with Ampro extensions
Additional Onboard Functions
- Real time clock; requires external 3.0-3.6V battery (Tadiran TL-5242/W or equivalent)
- Serial/parallel controller:
- Two PC-compatible COM ports with full handshaking (82C50 equivalent)
- On-board generation of +/-9V for RS232C signal levels
- Parallel printer port with bidirectional data lines
- Two 32-pin byte-wide memory sockets:
- One DIP socket, usable with 32K-1M byte EPROMs, 32K-512K Flash EPROMs, or 32K-512K SRAMs
- One PLCC socket, usable with 128K-1M byte EPROMs or 32K-512K Flash EPROMs
- RTC backup battery converts SRAM in DIP socket to NOVRAM
- Software-controlled +12V programming power for Flash EPROM
- Software-controlled write protect
- Configurable as 32K-, 64K-, or 128K-byte window, addressed in the range D0000-EFFFFh
- 1K-bit configuration EEPROM, with 512 bits for OEM use
- Watchdog timer:
- Utilizes real time clock alarm function
- Timeout triggers hardware reset or non-maskable interrupt
BIOS Enhancements
- Solid State Disk (SSD) support:
- Substitutes EPROM, Flash EPROM or NOVRAM devices for normal floppy drives
- SSDs may coexist with standard floppy and/or hard disk drives
- SCSI services:
- Supports DOS-based system operation using a wide variety of SCSI drives
- Adds a unique SCSI/BIOS function to simplify development of custom SCSI applications
- SCSI and IDE hard disks may coexist
- Extended floppy services: supports all PC and PC/AT capacities, including 360K, 720K, 1.2M, and 1.44M byte formats
- Watchdog timer support: initializes onboardwatchdog timer: adds BIOS function for use by application software
- Serial console option: substitutes an ASCII terminal or other serially-connected device for the standard PC keyboard and display
- Serial loader: allows download of executable code from a remote device prior to system boot
- EEPROM access function: provides high level access to the 512-bit nonvolatile OEM data area in the configuration EEPROM
- OEM "hooks:" execute custom code prior to system boot; allows system customization without BIOS modification
