iiUpdate
Built the iiBusboard and iiBackpack this weekend:
Here is the backpack installed on the Teletype:
The bus appears to be totally solid using the iiBackpack. In the video below, each metronome tick is setting 16 random voltages, sending 20, reading 8 param potentiometers, and setting the four internal cv values.
Iām able to change the script to send to dozens of nonexistent modules without hiccup. This is the real acid test to see if there is an appropriate amount of pull-up resistance on the bus. The iiBackpack passes with flying colors.
Last Chance to Add an iiBusboard or iiBackpack to Your Reservation
Letās consider this the last call to add an iiBusboard or iiBackpack to your TELEX reservation. In the next day Iāll put an order in for the appropriate number of PCBs and components. Again, you will need it if you are planning to connect more than a few modules to the ii bus.
Progress Update
Moving on to the TXo now. Prepping panels today and I will most likely start installing jacks and LEDs before the sun goes down.

@sakul - havenāt taken readings for the modules. Iāve been pretty swamped building them and, frankly, a little nervous about taking the readings and frying something. Iām planning to do it at the end of the process.
@martinmestres - certainly! If you have more than a few modules connected, you will need one of the bus board options to have stable communications between modules.
