[comp.misc] High-speed Static RAM board for VMEbus

ssm@munsell.UUCP (Steve McLafferty) (12/11/87)

I am looking for pointers to a VMEbus Static RAM memory board.  Size
is not important, but the following features are required:

  -  VMEbus Revision C.1 compatible.

  -  High speed.  The faster, the better, but at least under 150ns
     access times for read and write.

  -  Supports A32/D32 transfers.

  -  Supports Block Mode Transfers.

In my search, I have found many boards that meet the first two
requirements, some that meet the first three requirements, and none
that meet all four.

The fastest board I have seen is a 256KB board made by Everex and 
marketed by Nissho Electronics, with 40ns access time for writes and 
70ns for reads.  Unfortunately, it does not support Block Mode Transfers.

Any advice (e-mail preferred) would be greatly appreciated.
