I would be surprised. I pulled back a bloody stump the last time I mentioned the MicroVAX I to the VMS guys. My original design concept for the Firefox QBus Adapter Module involved having a dual-ported memory between the MBus and the QBus. The device drivers would copy data to and from this memory before or after performing DMA, as appropriate. This would have worked nicely and provided acceptable performance. However, I made the mistake of describing the arrangement to VMS people as "just like the MicroVAX I"; since the MicroVAX I doesn't have a scatter/gather map, the device driver has to do this to cover that lack. I was rudely informed that VMS no longer supported the MicroVAX I, and good riddance. So, the FQAM wound up being a really ugly and slow QBus adapter that worked much more like the traditional QBus adapter. Roger Ivie ivie(a)cc.usu.edu
