Hello Mark,

These are the test results with the machines that was easy to reach, I surely have other 71B elsewhere, I have to dig deeper.
Fortunately, my limited testing sample shows this timing problem seems affecting very few units.

Test cases:
Code:
Test #1: POKE "2C000","0" → Expected: HP71:xxxx
Test #2: POKE "2C000","1" → Expected: HP71:xxxx FTH:1B EDT:A KBD:C STRU:A MATH:2B JPC:F05
Test #3: POKE "2C000","3" → Expected: HP71:xxxx FTH:1B EDT:A KBD:C STRU:A MATH:2B JPC:F05 ULIB:c

Test results:
Code:
Serial     : Back    : Battery : VER$  : Status
2845A00123 : Plastic : Foam    : 2CDCC : All tests passed
2724A00900 : Plastic : Foam    : 2CCCC : All tests passed
2713A00041 : Plastic : Foam    : 1BBBB : All tests passed

2401A00190 : Metal   : Spring  : 1BBBB : All tests passed

Note: SN:2410A00145 → all three MultiMod modules failed to work but the FRAM71 module is working with this unit
