What 変なのあった refers to here?


I am uncertain what 変なのあった refers to in the last sentence.

I think it refers to different computer models. Perhaps, a person who brought
these computers?




変なのあった just means "there were strange ones", where "ones" refer to minor
computers other than 9801 series. 変な is "strange", の is "one/thing" (noun),
and あった is the existence verb used with an inanimate thing.
