hello, the 2 sticks on the left are the ones that this motherboard did recognize, but they have low capacity, the sticks on the right are the ones i tried and did not post (all of them have chips on both sides)
The ones that do work are clear: DIMMs with 4Mx4=16Mb chips; 16 of those makes 32MB. They are being detected correctly. They're 10ns chips, so rated to max 100MHz (maybe just 66MHz)
I'm afraid the pics of the ones that don't aren't good enough for reading the actual chips themselves on the others, but if they have 16 chips, they look like 8Mx8 chips (64Mb), which should be perfectly fine. Small chance they may have 16Mx4, which are out-of-spec, but brands like Micron and Infineon tend to stick to standards, so that's highly unlikely.
They do look a bit dirty, so I second the suggestion to clean the pins. Just get a little rubber and rub it along the pins on both sides of the DIMMs. Blow off any residue, then give them a try.
this second picture is about all my 128mb sticks i have that are pc133. that i will have to try once i get some free time.

the ones on the left are single sided, and the ones on the right are double sided
The 128MB DIMMs with 8 chips can only have 128Mb chips with 16Mx8 architecture. They are definitely OK for the MVP3 memory controller. The Micron and Samsung DIMMs should be excellent quality. There again, give them a clean.
One good thing to do is take a known-good board to test the DIMMs in. If the DIMMs are dead, no surprise that they don't work on your M577.
