IBM PS/2. Got it for free along with an original HP Deskjet printer. It originally ran MS-DOS until a family friend gave us an old floppy set of Windows 3.1.
The PS/2 was ancient by that point but it probably helped convince my parents that a PC was a worthwhile investment. Creating documents in Word was a lot easier than using a typewriter.
Even when I worked in an office, I would send ALL my important correspondence via email. An email provides CYA evidence. Talking to someone in person does not.
Edit: if it's really that important and your still not getting answers, YOUR supervisor should be the one pitching a fit at the party's concerned. Making sure you can do your job is their job.
