HAI Omni engineer/developer thread

Here's a schematic of the EPROM jumpers described in post #16. The flash chip is completely disabled by removing the jumper, perfect if you want to use the EPROM socket for an emulator or a chip with different firmware. HAI likely used this for initial/recovery programming of the firmware flash.

EDIT: I've confirmed this on a 4.0b firmware flash board by removing the JP10 jumper and installing a 3.0 chip eprom. The panel started up after a short delay and showed 3.0 firmware. It erased the installer code and other things (DCM phone number, etc.) in the CPU internal eeprom but other setup info seems to be there. Removed the eprom chip and put back JP10 jumper and panel starts up with 4.0b firmware. We now have a easy way to reset installer code on a flash board!

I must be missing a step. I bought a used Omni2e 5 serial port version. It seems to be working. I can check zones for example. I can ping it on my network. Since I don't have any codes, I removed Jumper 10 and put an Omni 2e eprom (2.15a) on the board. It never came up on the eprom. It turned on the leds for power, phone off-hook and one of the network leds.
When I remove the eprom and put J10 back, it's back as I originally got it. What am I missing?
Thanks

No bent pins? How long did you wait? First power on will appear dead while it takes 2-3 minutes erasing and re-writing memories and the STATUS led won't blink until it is finished. Don't power off during this time. If no change after 3 minutes then something is wrong.

No bent pins, waited longer than 3 minutes, tried 3 different eproms. Status led stayed off.
