Modified HP-71B MultiMOD Issue

[BitWiz]

The issue is my sped up 71B running at about 866Khz. This is too fast for the multimod. Here are my choices:

1. Find a way to switch the speedup on or off. My HP-41 has a 2.3X speed up that is switchable.
2. Replace the multimod with a device that can handle the speedup. Will the FRAM71 work at 866KHz?
3. Get real Forth and a Real 41 Translator modules and swap them manually as necessary
4. Remove the speedup. This is a last choice.
