Dear Mailing List:

Are there any experiences, tips, tricks, ... for sharing a B004/B008
compatible transputer board (with or without DMA to the PC) hosted
by a 386 PC compatible and running DOS-based transputer software
between multiple users using IGC's VM/386 Multiuser DOS multitasker?

More specifically:
* Is it possible to access the transputer from within VM/386?
* Does VM/386 know about transputer boards? Does it have to know
  about them? I.e. must I write a VM device driver for it (and is it
  possible to write one?), or may I access the board without a specific
  device driver?
* Is it possible to make the board a device which can be allocated
  and released on demand by individual users? More important, is
  the board protected from access by other users while allocated
  by a user? If I have several boards on different I/O addresses,
  may I use them as independent devices?

Is there any other software which might do the same trick (i.e.
sharing one transputer board between many users on one PC)?

The reason for my question: VM/386 seems to be by far the cheapest
method (both in hardware and software) to provide multi-user DOS
facilities with shared files, and we are considering it for our
transputer students lab.

Many thanks in advance for any help!
