CMT 64Kb RAM module for HP-71b question

[mfleming]

Ah, you're right. I was a power of two off on module address space occupancy. I don't see ULIB52 in the version list or MEMBUF listing. Could you poke a "3" to enable it? I also haven't seen the HP-IL ROM at 40000 before either. Looks like I'll have to hook up my PIL-Box and load MEMBUF myself!

The OP's description of a crash after a few minutes of operation implies to me that there is an address range overlap between two devices, both of which want to drive the data bus on a read. I take it you're not seeing that...
