It was the 155th MakerBot, a Cupcake. I got the kit back in the day but gave up after multiple catastrophic extruder problems. In Jan 2015, the pain of not having a printer grew too strong and I decided the corpse of my Cupcake was still much of a printer. I gutted the electronics and extruder and adapted parts from other RepRap type machines.
Cupcake155 has the following features:
* 0.3mm nozzle (adapted MK8 Prusia Extruder)
* RAMBo motherboard (http://reprapelectro.com/product/rambo/)
* Wifi-endowed Raspberry Pi running Octoprint
* Dedicated Arduino for Illuminatrix Lighting system

3mm Aluminum Build Plate
A local machinest provided some 100mm x 100mm x 3mm build plates, they're held on with tape.
In Cupcake155 Episode 3, I basically explained that I was having very frequent tripping issues during longer and more complex prints. I found that printing from SD vastly improved my success rate. I had to dig around a few schematics to figure out an SD adapter that'd work, as I didn't want an LCD panel on my printer (Octoprint's way better).
Cupcake155 Episode 2 on my website was posted about a year ago, it explores the key process I went through as I adapted the RAMBo and MK8 extruder to work with the Cupcake platform.
You're most welcome Ben. Yeah, I spent a few hours on this. I empirically computed the steps/mm as I probably mentioned somewhere. I measured many many many times and worked-out the average which seems to work extremely well. The RAMBo was probably overkill, but I love it so much.
I also highly highly recommend printing from SD and a cooling fan is very worth it.
Thank you! This helped getting my old cupcake up and running again. I used RAMPS, but have the same extruder/hotend. I had to double the steps per unit, I think I must have 1/32 steppers. Saved me a ton of time!

I'd love to see some pics.
