Thanks to Devin I can now say that his 9143 cartridge appears to be the AH01 model, even though the stickers on it say otherwise:
NC: 9022 729 14301
No: AH00 9323 000076
However, the low level tests say something different:
PHILIPS - CDI FMV Low Level Test Rel 1.0
0. Exit FMV low level test
1. Writing to a default RAM address
2. ROM parity check
3. DRAM test
4. DRAM test extended
5. Video Host interface test
6. Audio Host interface test
7. FMV test menu
8. DSP test menu
9. Pal test menu
Please make a selection: 2
ROM Id: 03 CSUM0: 46ea
Rel nr: 11 CSUM1: 50ff
Note the Rel nr which is 11, which is in the range for an AH01. Somebody's been lying to us :-) It must be either the stickers or the Interactive Engineer...
At first glance the hardware appears to be mostly functionally identical to the other Gate Array cartridges, judging from the device register accesses made by the drivers.
The edition numbers of the driver modules are the same or lower then the AH02 cartridge; no surprise there.
