Application: Industrial control, factory automation, networked real‑time embedded systems, no‑FPU applications
Key Identification:
MVME148‑001 = MVME148 standard configuration, 16 MHz, 4 MB non‑parity DRAM, no FPU, onboard Ethernet, SCSI, four serial ports, VME64, factory default firmware/EPROM loadout
The “‑001” suffix denotes standard production version, no special options or modifications.

1. General Description

The MVME148‑001 is a standard‑production, entry‑level 6U VMEbus single‑board computer, intended for industrial and embedded applications requiring onboard Ethernet but no floating‑point support. It uses the Motorola MC68030 32‑bit microprocessor at 16 MHz, with integrated MMU and 256‑byte unified instruction/data cache. No MC68882 FPU is installed on the MVME148‑001.
Onboard memory includes 4 MB DRAM (non‑parity), 2 KB battery‑backed CMOS SRAM for non‑volatile data, and a battery‑backed real‑time clock (RTC). Four 32‑pin ROM/EPROM/EEPROM sockets support up to 4 MB of boot/firmware storage; the MVME148‑001 ships with standard MVME148Bug firmware preloaded in EPROMs.
Peripheral interfaces: four EIA‑232‑D serial ports (Z8530 SCC), one Centronics‑compatible parallel printer port, one WD33C93 asynchronous SCSI controller with DMA, and one Lance AM7990 10 Mbps AUI Ethernet controller (onboard).
VMEbus interface supports A16/A24/A32 addressing, D08/D16/D32 data widths, master/slave operation, and system controller functions. The MVME148‑001 complies with VMEbus Rev C and is VME64 compatible.
