I see a "DTL-T10000H A" on eBay, and I'm wondering whether it's worthwhile to get or whether it has some limitations.
They were both used for PlayStation 2 software development and give identical functionality. The DTL-T10000 was the older model, made before they completed their specification for HDD support. Some of them had their MIF boards replaced replaced with a newer model that fielded the CXD9566R, making them compatible with the production network adaptors. The early Japanese model(s) is/are also incapable of playing the pressed discs from other regions. The DTL-T10000H is the newer model that left the factory with the CXD9566R. The letter after the 'H' (i.e. A for America) seems to be regarding the region that it was tailored for, although all TOOLs are effectively region-free. There were also two possible PCs that the TOOL would include: a Pentium 233 and a Celeron 566 model. Since it is officially used as a communications processor, it does not matter much. Some TOOLs had the DTL-T14000 emulator board installed, which you may be able to spot from its back since it is a PCI card (it would have one less vacant PCI slot than TOOLs without one).
This is the one I'm seeing on eBay: https://www.ebay.com/itm/PS2-Tool-D...n-2-Development-Console-TOOL-Kit/263490129046 Does that have the DTL-T14000? I don't know how to tell. Also, is $1500 a reasonable price for one of these?
I think the folks here would say that $1500 is expensive, and is why eBay has some notoriety here. There's no DTL-T14000 installed on that set, since there are two PCI slot covers.
There's another one from the same seller for $999: https://www.ebay.com/itm/PS2-Tool-D...135968?hash=item3d593c67a0:g:Px0AAOSw5Ztaf7t8 It's a DTL-T10000H (no A) It's rather dusty, but other than that looks ok.
