Yes, the xx(x) number in the 27xx(x) EPROM series indicates the kilo (1024) bits. So indeed this is 2 KiB. This sounds OK for the application described, especia

This sounds OK for the application described, especially as it was no doubt written in assembly and obviously bare metal. When it does not fit but not far off it's when the fun of code optimisation kicks in ;)
Edit: Very interesting how easily available they still seem to be according to Google.
