I can still cope with pretty well any 1/4" tape here at home, with the

You can just spin them into the computer at 15ips and adjust the sample
rate to convert them...!

I've done much the same thing with some 1/4" tapes recorded at 1 7/8 ips,
playing them back at 3 3/4 ips and using CoolEdit to stretch the time scale.
The only problem is that you need to copy and convert before you can decide
whether the material is worth keeping!

Frequency response?
Did tape use HF pre-emphasis and was it different for different tape speeds?
Dolby would complicate things even more.
