This unit
The Emerson/Mizar 8115 is a 3U x 160mm VMEbus CPU module engineered for industrial and embedded systems requiring master-level bus control. Built around a 68000 or 68010 processor, this module delivers complete VMEbus arbitration and interrupt handling capabilities with integrated memory and expansion flexibility for custom applications.
Technical Specifications Processor & Clock Speed
68000 or 68010 processor operating at 10 MHz and 12.5 MHz with zero wait states Memory Architecture
512KB dual-ported dynamic RAM accessible from onboard system and any VMEbus master
RAM address mapping: $0000 to $07FEFF (onboard), $E80000 to $EFFFFF (off-board via PAL reconfiguration)
Two EPROM sockets support 2764, 27128, 27256, or 27512 devices for up to 128KB total capacity
ROM base address: $F80000; initial stack pointer at $F80000, program counter at $F80004 VMEbus Interface
3U x 160mm form factor; P1 connector installation only (P2 installation causes damage)
Full VMEbus master with configurable interrupt response to all seven VMEbus interrupt levels plus onboard interrupts
Dual BIRQ1 & BIRQ2 signal lines for VMEbus interrupt requests IRQ1–IRQ7
Key Features
MXbus connector (S1) supports custom expansion with full address, data, and interrupt line access
Configurable PAL-based memory address selection
Interrupt handler responds to any combination of VME or onboard interrupt sources
P2 connector access to upper address/data lines and user-defined signals on expanded boards
Typical Applications
Serial or parallel port expansion
Floppy disk controller integration
Additional memory modules
Custom industrial automation and embedded control systems
Compatibility & Integration Direct compatibility with Mizar MZ 8800 Series MXbus expansion modules via S1 connector. Module design supports straightforward customization to full 6U x 160mm configuration.
