Do T4 and T8 transputers mix? ( - in a Meiko Computing Surface?)

We are on the verge of buying some T8's to put in our Meiko Computing Surface. However, all the compute boards which we currently own are made up of T4's (MK009's). Meiko say that there shouldn't be any compatibility problems. I thought I'd check with the network before we purchase. Has anyone had any experience of mixing T4's and T8's in a Meiko Computing Surface? What are the results? We're running MMVCS (the Meiko multi-user s/w). Is it sensible to keep different types of transputers in separate domains? Thanks in advance!

We are running standalone (i.e. no sun on the front) with MMVCS and 2 (yes, 2) MEiKOS processors. One of these is T4 and the other T8. We also have a variety of domains, some mixing T4 and T8. It's probably not a good idea to mix processor types inside domains. But it doesn't really make much difference elsewhere. For example, all our spine processors (off which the domains hang) are T4. Most of the domains are all T8, but some are T4, some have T4 user seats with T8 processors in the domain. The biggest problem with having different processor types around is that you need to keep software for both around too. You can also create havoc by loading T8 code into T4 processors (if you happen to be using a different boot file than that specified in the configuration). Good luck!! Tony Curtis, UKC
