. . . to run a little test for me? I still haven't ordered caps yet, so the IIsi fleet remains in mothballs.
I'm very curious about the Slot ID status of the vampire video subsystem when the IIsi is running off only a video expansion card. When there's no monitor or adapter connected to the DA-19 on the motherboard, the RAM normally sucked out of the system like blood from a vampire's victim is not buffered from the system for use only by the Video Subsystem. MoBo video is addressed as a PseudoSlot (a pretend expansion card if you will) in Slot Location ID $E. I'm wondering if the RAM's offline, the whole subsystem might be offline? Will it still be reported as occupying Slot $E?
If someone could please test a IIsi in this manner: a Video Card in its PDS or a NuBus card in its adapter and nothing hanging off the video port. If you don't have it already (you all need to get it for basic hardware testing) download and install TattleTech to run the NuBus/PDS report. Save the report results as a text file and post it here for me, please?***
My guess is that it will still show up as being in that location because it has the equivalent of a physical Video Card's Declaration ROM as part of its makeup, but you never know until you know. Even if it shows up it still may not matter anyway because it will be dormant, with no memory to address.
Since it won't be addressing any memory, there shouldn't be any possible memory conflict with a PowerCache Accelerator.
I'm thinking about hacking together a passive IIci Slot/PowerCache adapter for the IIsi as an experiment,. Seeing TattleTech reports before deciding to order the connectors would be a big help to me and some welcome relief to the toy budget.
TIA

***At the same time TattleTech will tell you the particulars about your Video Card and at which of the three available slot IDs it is located. This is what I've long termed "DeclROM spelunking." It's the way to find out what a NuBus or PDS card is by reading the info off its ROM and without posting one of the many "can you identify this card" threads we've had over the years. If nobody knows offhand what your card might be, you'll be told to go through this to find out anyway!
TattleTech reports on all kinds of neat stuff . . . try it, you'll like it!
