Nonsens. VME is, was, will be an 68000 bus. That is 24 bit adress and 16
bit data.
There is an enhanced VME bus (32/32) but even this one does not run at      
MHz. It is impossible to charge/discharge the input capacities of the
bus buffers over long bus lines (inductive resistance) at high speeds.

The VME bus was (almost) never used for memory expansions. It is for
(fast) I/O (thats my point of view).

There are hundreds of VME cards availeble (probably more in Europe,
since the VME Bus was an European idea). We'll see, wich will run, but
probably most of them.

In fact, I would like to have VME/VMS/VMX bus in my home machine. But
they are far to expensive for me :-(

 Well, Apple Corp has tried that with their

The NuBus is is pretty new (compared to VME). Wait a little longer; it
is not trivial for the hardware engeneer to handle a bus, that is
supposed to support multiple processors (bus arbiting).

Do it. I'll probably wait for Dave Small to emulate it with the TT :-)


Hello Atari: what about Unix on the TT? It is the ideal machine (MMU,
speedy, intelligent I/O (with VME serial cards...)).

Mr. L. Tramiel said "We are wrking on the port."

How long will it take, and what will it be? SYS VR4?
