So I have 8sid chips (8580r5) Can I use the 8580sids on the wilba6582pcb that’s available on avi showtech?
yes, totally.
Actually you should swap them with me for 8x 6582A SIDs… it’s not called MB-8580R5 now is it? 
Think I bought those chips from you wilba , long time ago 
But hey i’m finally going for it
