== 40pin Gate Array 40008 or 40010 (HSG3130 or HSG3170) ==
Newer versions of Gate Array, rearranged pin-outs (other than 40007). 40010 and 40008 have same pin-outs. 40010 has no cooling plate. 40008 seems to be rare (no info if it has cooling plate or not).

== 100pin Gate Array AMS40226 (ARN4) ==
Pre-ASIC (late cost-down models).
See CPC6128 "ULA/DS" section in service manual.
Aside from Gate Array, it includes CRTC, probably PAL, FDC select/motor, DRAM
addr/data bus, RESET signals.

Printer port 74LS273 chip is replaced by TWO chips: 74LS174 and 74LS175 (the
latter one includes strobe inversion).
UNDOC1/UNDOC2 are probably VCC/GND. UNDOC3/UNDOC4 are unknown.
== 160pin ASIC (CPC+/GX4000) ==
Includes Gate Array, CRTC, PPI, 8bit printer port, FDC select/motor, keyboard
mux, analog I/O, CLK dividers, new CPC+ features (video, dma), cart rom bank,
cart ACID counterpart, 128K RAM banking, DRAM addr/data bus, RESET signals.
Lacks external PB0 and PC0-3 pins. PB/PC are one-directional. PB5 combines
AMSDOS bank and /EXP input.
