What to do with my Collection?

[rprosperi]

Excellent choices, these depict the full history and amazing breadth of support the 41 family enjoyed from the community and 3rd-party developers.

The only essential missing item IMHO is the AME Port-Extender. Certainly all 41 power users of the day got one and confused both themselves and the 41 bus while learning to set all the dip-switches.

Arguably the Advantage ROM should also be added to the list of Iconic Modules, but this is a matter of taste and purity.

If you're considering the Devil ROM you probably should have the HP-IL Module too; on second thought, this should probably be included anyhow.
