I've also been chasing down the history of the ASICs used on 'Irma' boards
and you can see the chain of acquistions. SMC and UMC were even in the
Irma ASIC business but it's unclear if they did their own firmware or copied
someone elses. I need to sit down with my notes since it gets really
confusing. National, for example, built a coprocessor ASIC (DP8344) but
sold a boxed PC card product with an SMC part on it.
