I like the mishmash of colored PCB. I built this TF536 a couple of years ago but could not find a full gold 030 with mmu until a couple of weeks ago..... At least for a price I was willing to pay. I have a bunch of EC variants I have pulled from Cisco 2500/2600 routers but it is just not the same. Just got MMULibs installed and configured, before the drive speed was 800k or so and now it is 4-5 megs. Running Kickstart 3.1 with a bunch of patches and it is switchable with 1.3 or whatever I want. The romulator comes up with a prompt on cold boot and you can select whatever you load on to a micro sd card. Slick little device. Next: need a NIC, build another plipbox I suppose.
