Want to by windows 95

I have a 3 year old Compaq Presario 4122
that is used for special needs. It came with windows 95 and I loaded 98 on a year ago and it ran like the old IBM AT’s. Tried to reload 95 from backup diskettes and the system iwll not not boot.

Want to get windows 95 running again but stores, compaqy and microsoft does not have software.
Any suggesstions where I can get windows 95.

Thanks
