Hello folks - yes, UPURS will work with any 6522-based ‘User Port’ but in some cases, depending on the details of host machine, slightly different versions of UPURS have been configured to support either different physical addresses of the port or to support subtle timing nuances. In specific answer to the question and assuming we are talking about Dave H’s new AP5, the latter not only supports UPURS but has specific connection points for both my UPURS and I2C functions via (I think) Pl1 and Pl2 respectively. I think the Elk UPURS version used for the AP5 is V2.0E which includes an MCG loader but if someone can confirm that the AP5 User Port is at the same address as my EUP board then UPURS V1.0E will also work fine. Apologies for slight wooliness in my memory, its been a while since I produced this stuff, maybe Dave H can add some confirmations of version numbers etc. In terms of an original AP5, it depends where the User Port lived, was it the same address as Dave’s new AP5?
EDIT : We overlapped Dave! Thank-you and it looks like we are being consistent!
