Just add a 488 bus interface if you want one.? Once you have a processor, you could go USB rather easily if that's a plus.

Harvey,
????Also if all the data is digital as well it would be a nice to have to be able to dump out a screen cap to flash somewhere. The good news is there quite a bit of space available once the tube is gone. To add a few boards.
Just gonna throw this out there: GPIB?

If I were to try that, I'd first look at flash a/d converters, at least
8 bits if not more.? That gives you a digital output of the X and Y channels (scale input first!).? For an FPGA, I'd suggest (for
experiments) getting one that fits the FPGA tools you already have (XILINX OR ALTERA), and one that has about 50K or more gates, the more the better.? The X and Y inputs specify which dot on the screen to set, and if you have that in a delayed queue, which dot to erase if you want persistence on the screen to be variable. You'd want a microprocessor to talk to the display to set up scale factors and draw gridworks or whatever you decide to do, and an overall control of the display.
At this point, it would be a color display.
