I found 2MB worth of 256x4 DRAM for my 2091 and it made a huge difference in
loading times compared to the same board and drive with no ram at all. Best
place to find it is on old ISA/VLB video cards where it can be found
socketed for easy removal (and can always be put back in the video card if
needed).
I looked in my junk box and found a couple of
PS/2 graphics boards
with the ROMs missing and one burnt up. Each had 8 TI TMS44C256-12N
DIPs, which are now running nicely on the A2091.
Perfect.
As soon as I finish cooking and eating dinner,
I'm gonna see if it
juked up the abysmal disk I/O a little.
I'm sure it will help loads. The A2091 isn't a screamer of a
controller, but DMA to Zorro-II FAST RAM should be quite noticable.
The whole list ganged up to teach me some
memory basics. :)
So I saw. :-)
