From what I read that chip was working, but needed rather expensive SRAM since it used the 'no badline' approach of the original VIC. That meant 2 memory cycles per 8 Bits displayed. I could be mistaken, but I think the 6567 was the first VIC that used DRAM, everything before used SRAM, mostly 2114s and later 6116s. Look up their price at that time.
