Series 3350, S/N 148264-010

Booger is one of a pair of XL 590 systems I purchased secondhand for an ambitious in-house infrastructure project I never finished. I selected this particular model for three reasons:

1. several identically configured systems available from the recycler,
2. an abundance of built-in I/O, including SCSI and ethernet,
3. four EISA slots, given the veritable cornucopia of EISA stuff I already had lying about.

Booger was to provide the development environment and testing sandbox for a Linux From Scratch project to turn the other XL 590 into a firewall/router appliance. I still intend to get it done, as I need something capable of routing between the currently non-intercommunicative FDDI, ethernet, and token ring networks in the lab. Booger, however, will not be the development host; I had plenty of time to arrive at this conclusion while I waited for it to compile GNU libc 2.2.4 the first time.
