Compatibility with 1001 unit?

Post by TwinFami » January 9th, 2019, 7:17 pm

My local store got in a PlayStation 1001 unit in box and since I’m an in box collector and it’s the best unit made, I was wondering how it holds up for the PSIO in comparison to the current unit I have which is the 5501. The unit is $70 in box so I definitely want to make sure there’s no issues with the switch board or PSIO on that mode before I buy it and have it modded.

In my case I have the SCPH-1001 (composite outputs on the back) and it works fine with the PSIO. You might want to get the caps replaced as a maintenance measure as it can be potentially beneficial for this particular model. That said it is my understanding that all PSIO compatible models perform the same.

I’ll second the fact that the PSIO works just fine with this model (despite my soldering job not being the best)

I use a SCPH-1002 (early PU-8 board with the older 80-pin HC05) as my main gaming unit and of course, it works fine :P

Good point mentioning the board revision, I would try to avoid PU-7 (systems made very close to release date) due to the texture banding issues.

The SCPH 1001 model which is PU-8 also has the problem of banding.
I think this problem has been fixed only on PU18 or the last PU8. I say this because I already had SCPH 1001 (PU-8) and had this problem of banding in the shadows.
Here I installed the switch board on an SCPH 1000 (PU-7) and an SCPH 5500 (PU-18).
I installed this two models because the SCPH 1000 has a slightly better sound, the bass seems to be stronger and the sound of this model seems to be higher, and the SCPH 5500 has good sound quality and does not have the problem of banding.

Eu acho que esse problema foi corrigido só na PU18 ou nas ultimas PU8. Eu digo isso porque eu já tive SCPH 1001 (PU-8) e tinha esse problema de banding nas sombras.
Aqui eu instalei a switch board em um SCPH 1000 (PU-7) e em um SCPH 5500 (PU-18).
Eu instalei nesse dois modelos porque o SCPH 1000 tem o som um pouco melhor, o grave parace ser mais forte e o som deste modelo parece ser mais alto, e o SCPH 5500 tem uma boa qualidade de som e não tem o problema de banding.

From what I researched, GPU with 160pin has the banding problem and on the GPU with 208pin the banding problem has been fixed. The PU-8 has both types of GPU depends on the date of manufacture.

Yes, all PU-7 units have the banding issue, which is why we can recommend to always avoid this revision.
For PU-8, only the earliest ones have banding, so we cannot say to always avoid these (mine does not have this issue for example).

The best advice is simply to stay away from consoles from close to release date (late '95 in the case of North America).

I actually went with the SCPH-7501 a few years ago, because it was the smallest MB revision that still had the parallel port. Made it much cheaper (literally HALF the size of older ones) to ship to Australia for the switchboard installation!

I have a 1-658-467-12 board and it looks very similar to the 208-pin GPU version in your picture, but IC310 is much smaller on my board. It has "SEC KOREA 546Y" printed on the top. Sadly, it's the 160-pin GPU version... I thought it was hard to come by and of course I get one... :<

I've found an easy way to tell if it's one of the early 160-pin GPU SCPH-1002s without even unscrewing it. After opening the lid, there will be "HIRAI SEIMITSU CO, LTD." engraved in the plastic. Later PU-8s don't have it. Even the colour of the plastic is visibly different. I mean, it's a visibly different shade of gray.

Amazing info. I have a pair of 1001 units, and they were always different, in that one displayed banding, while the other did not. I never found out more than the "newer" unit was a pu-8 and is most certainly a 208 pin gpu. Somehow, it is the only unit I own that has worked without issue since new.
