Dear Rich and Dave,
A recent thread on comp.sys.apple2 makes us wonder if there or what are the differences when the DIP switch is enabled for the IIgs when a 3K is used within a IIgs. See https://groups.google.com/g/comp.sys.ap ... JqhQIZ9E-c for more information.
We have not yet dug into the ProDOS version or that is also related to Peter Ferrie's message from late 2018 in that forum. But, it seems some programs crash from time to time. OK, it can be the ProDOS port, it can be the MLI or Smartport calls but, still.
What are the differences (apart from the CDA) when the DIP switch is IIgs-enabled within a IIgs? Is that the support for Smartport extended commands? Are there interrupts used? Etc.
Thank you for your help,
Antoine
