New micro memory inc. mm-6326D vme vsb memory board 64M
BRAND NEW Micro Memory Inc. MM-6326D VME VSB Memory Board 64m. Various serial numbers, came out of a sealed box and sealed package I opened for photo only, Guaranteed to be brand new, sells for over $1000 online, see below for specs or contact MMI directly,
Here is some online info we found for your reference ONLY
A 64 Mbyte, Super Fast, Dual Port, VME/VSB Compatible DRAM Memory Module
* Capacity: 8M, 16M, 32M 64M bytes
* Cycle/Access Time (nsec): Read 125/75, Write 125/50 (Block Transfer-BLT, Page Mode and Bank-Interleave)
* Compatible with VMEbus Rev C1 and VSBbus Rev C with A32/A24/D16/D8 (UAT) for VME and A32/D32 for VSB
* Block transfer for sequential access for both ports
* Parity generation and checking for error detection on each byte
* Module selection on 1 Mbyte boundaries, jumper-selectable for lower and upper limits on each bus
* VMEbus Control Status Register (CSR) for parity reporting and control
* Write-Wrong parity for diagnostics
The MM-6326D is a high speed, dual-port, single card slot, high density memory module that provides up to 64 Mbytes for VME/VSB systems. It is intended for high performance applications employing Bank-Interleave, Page Mode and Block Transfer at data rates greater than 30 Mbytes/sec. It also supports sequential access (BLT) of 256 bytes on the VME and 64 Kbytes on the VSB bus.
The MM-6326D is compatible with MVME130/131, MVME135/136, MVME141 and Delta Series systems.
The Control Status Register (CSR), located in the short I/O address space, stores and reads byte-wide parity errors detected on the VME/VSB buses. The other bits enable Write-Wrong parity for diagnostics, disable VME-port and determine whether the memory is CACHEable on the VSB bus. Parity generation and checking are provided for each byte; parity status is stored and transmitted via BERR*.
Reliability is ensured by burn-in and running memory diagnostics that check operation for 48 hours while temperature-cycling boards from 0 to 60 degrees (Celsius).
