# The "cost-down" CPC6128

The "cost-down" CPC6128 is a revision of the CPC6128 design. It was created in 1988 to reduce the cost of manufacturing the computer. This "cost-down" revision has less ICs and a smaller P.C.B. The functions of some of the ICs from the original design have been combined into a single ASIC custom IC.

The CPC6128 "cost-down" revision ASIC contains the functionality of:

- the 6845 CRTC,
- the RAM management PAL,
- the 40010 "Gate-Array"

I hope to get a "cost-down" CPC6128, and then I will be able to identify any differences that might exist between the original CPC6128 design and the "cost-down" revision.

# The "cost-down" CPC464

The "cost-down" CPC464 is a revision of the CPC464 design. It was created in 1988 to reduce the cost of manufacturing the computer. This "cost-down" revision has less ICs and a small P.C.B. The functions of some ICs from the original design have been combined into a single ASIC custom IC.

The CPC464 has other revisions, but these all have the same number of ICs.

The "cost-down" revision ASIC contains the functionality of:

- the 6845 CRTC,
- the 40010 "Gate-Array"

I hope to get a "cost-down" CPC464, and then I will be able to identify any differences that might exist between the original CPC464 and the "cost-down" revision.
