|
||||
*---------------------------------
|
||||
* When Motorola released the 68000 processor 1979 the ambition of the deisgners
|
||||
* was also to standardize a versatile CPU bus to be able to build computer
|
||||
* systems without constructing PCB:s from scratch. This become VersaBus but the
|
||||
* boards was really too big and the computer world already saw the systems shrink
|
||||
* in size. Motorola's design center in Munich proposed to use the smaller and
|
||||
* already used Euroboard form factor and call it Versabus-E. This later became
|
||||
* VME which was standardized in the VITA organization 1981

* History of Mizar
|
||||
*-------------------
|
||||
* Mizar was one of the first companies that released VME boards in 1982-3 together with
|
||||
* Force Computers and Motorola. Their systems was often supported by OS9/68000 from Microware.
|
||||
* In 1993 Mizar discontinued their OS9/CPU board product range and focused entirely on DSP
|
||||
* boards. RTSI was founded by Mizar employees preserving the knowledge in OS9 as consultants.
|
||||
* In 1998 Blue Wave resulted from the merger of Mizar and Loughborough Sound Images.
|
||||
* Not much tech information availabe but I found some quotes about Mizar on the internet:
|
||||
*
|
||||
* From http://archive.org/stream/68micro-vol-11-num-02/V11N02_Feb1989_djvu.txt :

||||

|
||||
* " Mizar provides complete OS-9 solutions for the VMEbus. Mizar's VME CPUs
|
||||
* offer (he functions and performance your application demands. Our single
|
||||
* height (3U) VME processors are uniquely configurable computing engines,
|
||||
* Through Mizar's unique MXbus expansion interface, standard and custom side

* mailbox interrupt support. Standard MXbus side modules include additional DRAM.

|

* History of Mizar
|
||||
*-------------------
|
||||
* Mizar was one of the first companies that released VME boards in 1982-3 together with
|
||||
* Force Computers and Motorola. Their systems was often supported by OS9/68000 from Microware.
|
||||
* In 1993 Mizar discontinued their OS9/CPU board product range and focused entirely on DSP
|
||||
* boards. RTSI was founded by Mizar employees preserving the knowledge in OS9 as consultants.
|
||||
* In 1998 Blue Wave resulted from the merger of Mizar and Loughborough Sound Images.
|
||||
* Not much tech information availabe but I found some quotes about Mizar on the internet:
|
||||
*
|
||||
* From http://archive.org/stream/68micro-vol-11-num-02/V11N02_Feb1989_djvu.txt :

|
||||
* " Mizar provides complete OS-9 solutions for the VMEbus. Mizar's VME CPUs
|
||||
* offer (he functions and performance your application demands. Our single
|
||||
* height (3U) VME processors are uniquely configurable computing engines,
|
||||
* Through Mizar's unique MXbus expansion interface, standard and custom side
|
||||
* modules can be added to basic processors to create double-height (6U) boards
|
||||
* tor specific applications, 3U CPU options include 68010, 66020, and 63030
|
||||
* microprocessors, up to one MB of DRAM, serial I/O, real-time clock, and
|
||||
* mailbox interrupt support. Standard MXbus side modules include additional DRAM.
|
||||
* SRAM, and I/O.
|
||||
*
|

* Mizar's standard double- height (6U) processors provide additional features such

||||
* support, up to four MB dual ported DRAM, VSB memory interface, Ethernet, and SCSI.
