It's also worthwhile to mention that the V20/30

none of the Intel x86 members has, such as packed BCD string

I have never found a decent resource on NEC V20 special opcode
programming; the only stuff I've found has been on how to detect an NEC

last 20 minutes. Is there a resource for what the extended instructions
were, or is that lost to paper history?
