[comp.lang.smalltalk] Smalltalk/V286 with Sony Interactive Video

al@unix.cis.pitt.edu (Alan M Lesgold) (09/20/89)

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.
