We don't see one on YAJ very often, a good time to catch the pictures here.

Better ones from Sony MST-1000:

It must have cost a fortune in discrete components!

Definitely (at least to my mind) a much nicer looking unit cosmetically than the MSC3000/4000, I wonder how its video performance compares to these later units though, and especially bearing in mind the high quality innards that you note above Julien?

Indeed, it would look great beside a HIL-C1!

Based on the Yauc photos and other info, this looks very similar to the 1st generation of the MUSE LSI chipset.
Sure it has many ASICs, but as the name states it's already Large Scale Integration :)
The "original" prototype MUSE decoder consisted of around 3000 discrete ICs with 43 PCBs in a rack, and consumed ~1500W (and probably required at least two persons to move it).

The MUSE signal processing is done in the digital domain, but still, not all decoders do everything the same way of course.
The main focus of the development was on reducing the cost/size/power consumption-heat dissipation of MUSE decoders, but this doesn't mean that (all) newer decoders sacrificed quality over cost savings.
Characteristics of the filters used for interpolation can vary, which can make a difference.
And possibly different methods for motion detection were implemented in different MUSE VP chip(set)s.
Also, some decoders use 8-bit, others use 10-bit ADC/DAC circuits. MST-1000 should have 10-bit, but for MUSE LD players, that doesn't make any difference.
Many newer decoders can also contain additional video processing circuits to improve the image in their own way (e.g. "MUSE AI" feature in the Panasonic TU-AHD100(N)).
Fujitsu also developed a one-chip MUSE processor in 1995 (calling it 3rd generation MUSE LSI), stating that by using 7x7 filter instead of 7x5 (as in the 2.5th and possibly previous generation LSIs, maybe the prototype MUSE decoder used 5x4 for the 2D filter) significantly reduced ringing and improved horizontal resolution (400->480) in moving areas.
This also employed a 3x3 median filter instead of the previously used 3 tap high pass filter for noise reduction.

So, my guess is that the picture of MST-1000 shouldn't be bad, but newer decoders probably possess more "magic" features and can get more out of the input signal (probably mostly visible with moving areas).
But of course image quality is mainly subjective.
