Hi Andrew,
Thanks for the quick reply.
ASUS M4A785TD-V EVO motherboard with an AMD Phenom II X6 1090T Processor 3.2GHz, 4GB RAM, running 64bit Win7 with ATI Radeon HD 4200 display adapter with the latest driver (circa 2009)per windows update driver search. I see AMD has a 2013 driver listed ( https://support.amd.com/en-us/download/desktop/legacy?product=legacy2&os=Windows%207%20-%2064 ) but it would be good to know if that would solve the problem before mucking with an otherwise perfectly ryunning system. It’s my lab computer that runs all other lab equipment. Sure hope it will run this too. Have no plan to replace it. Hopefully there is some way to get the SA44/Spike to work correctly for a simple spectral analysis display (my main need). Thanks, Chris
