List of PSX console variations somewhere?

[CrazyImpmon]

Anyone know of such list? I know there were a few design variations from the original PSX that had the swap trick and was prone to laser problem due to cheap p0lastic railing, a later version that didn't have this, and yet another version that doesn't have the standard AV ports or parallel port, etc.

If you can still find an old Mod Chip site, they usually list out the models that the chip works with. These models are not always different on the outside, but the architecture has changed on the inside.

PSOne
SCPH 9000
SCPH 750X
SCPH 7000
SCPH 550X
SCPH 100X

Onlky differences in the SCPH models that you can tell from the outside is the 100x has RCA ports.

The SCPH 9001 also has no high speed parallel port.

They also moved the location of the laser housing.

On the 1001 models, they were on the lower left. On the newer models, they were on the upper right.

I have quite a few different PSX units including 3-4 different debugs but I got a really strange one traded in last week.

It was from the Cleveland Public Schools and had some stickers identifing it as such. I'll have to these out for the model numbers.
