We are developing an intelligent practice environment for complex electronic troubleshooting using Smalltalk/V286 along with interactive video. The video system our sponsors need to have us use is the Sony set-up (genlock and controller boards based on their VIEW system). It turns out that Sony remaps the interrupts in their video control software. So, we are building a scheme that caches the Smalltalk interrupt table before calling a sony routine and caches the Sony table before returning. Does anyone know of any pitfalls in this. Obviously, at least Sony was parochial and unwise, and who knows what Digitalk may have hidden, but we have to live with the two in this effort. --Alan Lesgold Learning Research and Development Center, University of Pittsburgh
