https://archive.digidesign.com/compato/os9/hd/cards.htmlaccording to this information, the samplecell II cards can be used in PTHD systems (192 i/o):
SampleCell II
SampleCell II Card without TDM module
The one exception is the SampleCell II card, although the TDM bus cannot be connected to the Pro Tools HD card because the SampleCell TDM Module is not compatible with Pro Tools|HD systems. SampleCell II cards can be utilized in Pro Tools|HD systems using Aux tracks to route the SampleCell I/O Analog outputs physically between the card and audio peripherals. In addition, you must install the DigiSystem Init v 5.1.1 in your Extensions folder. (included on the Pro Tools 5.3 CD) Playback is limited to samples at 44.1 and 48 kHz.
Note: The "Getting Started with Pro Tools|HD" guide (version 5.3) that ships with HD systems with Pro Tools 5.3 incorrectly states on page 11: "Do not use SampleCell hardware cards in a Pro Tools|HD system. Doing so can result in system crashes. Instead, please use Soft SampleCell which has been specifically engineered to support 24-bit depths and higher sampling rates." Although we do recommend using Soft SampleCell with HD systems, you can use SampleCell II cards as stated above. This information will be corrected in the next document revision.
Incompatibility with older SampleCell II Cards
A rev "QC" or later of the AMCC chip is required for Blue & White G3 and G4 compatibility. This rev number appears on the AMCC chip following number "5933". Older versions can cause your computer to hang while booting or when launching Pro Tools or DigiTest. QC or higher chip is required for compatibility with the PCI 2.1 spec. Ways to identify these boards are in the grid below:
Board

Manufactured Before
Board Rev Before
DSP Farm I
FF09226
7/9/97
Rev H
SampleCell II
HH02001
5/20/97
Rev D
If a customer has previously updated their board (or received a refurbished card), the serial number will remain the same, but the board rev will be updated (and the AMCC chip will have "QC" or later). Cards with the rev "Q" chip can be upgraded. Please contact Digidesign Technical Support by phone to arrange for a return authorization. Registration is required.
Note: All SampleCell II Plus cards are newer, and therefore already have the compatible chip.(The SampleCell II Plus cards are the same as the original SampleCell II PCI cards, but with the included 32 MB of RAM soldered on the card)
