TenTec Orion repair. Final part.

1/n

I very recently repaired a dead TenTec Orion.

The Orion was produced for 2 years, followed by the almost identical Orion II, with a color display and a slightly faster CPU.

As my Orion's problem was CPU/memory related, uploading a fresh firmware was impossible, with various error messages.

There are 3 major versions of the firmware, the last 2 requiring an hardware mod.

The mod allowed to reuse some parts of the "Orion II" firmware.

(To be continued...)

TenTec Orion Repair. Final Part.

2/n

Having failed to reinstall v2 and v3 firmware, I removed the hardware mods from the CPU board and tried to install the old v1 firmware.

The install started fine but failed several times (downloads stopped at 99.9%...), but I finally managed to install a firmware.

I wasn't done yet.

The many cards are plugged into a central motherboard, and the connectors needed some TLC after 20 years.

And The Orion was back to life !

That's where I was this morning.
