That's an incredible amount of memory!

My first PC was the Amstrad PC1512 around 1986. That had a whopping 512K or RAM. Still you could do things with it. The Gem graphical desktop (sort of like Windows) it came with was slow but there were text based things like the Wordstar word processor, etc. The PC had a life after I'd moved on to Windows and something faster. Mum wanted something to record units of treatment per patient, produce totals and simplify her increasing paperwork load so I wrote something and gave her the machine. It finally retired from the hospital when she did late 90s.
