It's wasn't till later that I realized my dad was absolutely right with this camera. It was more advanced than the AE-1 and I still have it and it still works perfectly. BUT, I found out about the X-700 and picken one up cheap on eBay, it has better flash control than the X-370 and a Program mode which is more advanced than the offerings on the X-370. I now own 2. I occasionally look out for an X-500/570 as what I've read say this is an even better camera, making it the best camera Minolta made prior to switching production to Auto-Focus
The aperture priority setting and flash system worked together like magic. I'd place it in the top 10 cameras of the decade. If it weren't for a couple of plastic parts, it would have been an even bigger deal.
(I had a canon T90 that had it and shot with a borrowed nikon 8008 that had it as well).
The T90 had a spot meter mode where you could use the center circle and tap and extra button (next to the shutter button) to have it average the exposure of all your spots.

Everything seems easier now that we're digital.
While I can't comment on specifics of the availability of aperture priority in 1980s SLRs, the two models you mention (t90 and n8008) are late 80s models (86 and 88 IIRC) where the X-700 was released in 1981.
The X-700s are terrific cameras, I shot with one for many years.

"C. Fn I –8 [Safety shift], is an expanded version of the EOS-1D Mark II N's C. Fn-16 [Safety shift in Av or Tv]. The function [2: Enable (ISO speed)] works in the P, Tv, and Av modes. If subject brightness changes erratically and the correct autoexposure cannot be obtained, the ISO speed is shifted automatically within ISO 100–3200 to obtain a correct exposure. Safety shift overrides the following settings: C. Fn I -3 [Set ISO speed range], C. Fn I -12 [Set shutter speed range], and C. Fn I -13 [Set aperture value range]. During continuous shooting, safety shift might be applied even if flash is used. It depends on the shooting conditions."
