1.
remove the original Amstrad link wire 2. install the provided 10K smd resistor in position R75 3. solder the provided signal cable on the spot shown in the photo - it is the same spot that the original Amstrad wire was soldered - PAYING EXTRA ATTENTION that it only connects to this spot and not shorting any nearby vias/components. |

My recommendation is
to replace the old and limiting stock mechanical HDD that came
with the system with a CF or SD card. I can understand some people might not like this - on a normal system I would say it makes no difference if you have a good HDD to use *but* in the crammed MegaPC the power and heat consumption gains are too great to argue against. The system will just run cooler (something that is REALLY needed as Amstrad did not add air intake holes on the MegaPC chassis , this is why the MegaCard bracket is so small as an attempt to compensate for that) and the 65W PSU will have lower load when working: both of these things will be beneficial in the long run for an almost 30 years old system. |
