MegaROM
,Note: In the picture above and also in the price list, I have chosen to use a header connector on the PCB. I did this because I intend using the MegaROM on both a UK CPC464 and a German CPC6128 and by using a header connector I can swap the connection cable to suit which CPC I'm connecting to. You may choose a direct connection to the PCB if you don't need this feature, dropping the price another few cents.

The Following EPROMs have been tested and are compatible with the MegaROM:
The finished PCB is 73mm x 73mm. The four holes (M3) in each corner can be used for mounting within a housing or as I have done here, adding legs to keep the PCB off the desk. If you use metal parts as I did, you will need to add plastic insulators beneath the metal parts to avoid short circuits or damaging the tracks that are routed under the metal.
Closing an IDC connector on a 50way flat cable can be a difficult task and if not done properly, may cost you a connector or two. I recommend first putting the cable in position and pushing it slightly closed to keep the cable in place, then place the connector in a bench vice with rubber between the metal of the vice and the connector, then slowly closing the vice on the connector until it reaches it's home position. You may have to re-position the connector a few times until it's completely closed. Bad connections with these connectors are the cause of many peripherals not working, the pins in the centre cause the most issues, so turn the connector 90° in the vice for a final squeeze to make sure these pins are properly connected. Don't try closing an IDC connector with a hammer, pliers or other tool that only applies pressure to a tiny area of the connector, it will break!
