Elusive 630 board

[Klyball]

I added the component names from the 540b schematic on the 630 board layout for composite out, i am going to populate it on the replica and see if it works, weird how its not on the schematic, maybe it was in the 630 manual if there even was such a thing.

I finished the 630 replica and tested most of the features and it all seems to be working quit well, one thing i cant quit figure out is , if you read the c1p manual it talks about using the 630 and gives some code examples. it states that when the 630 is installed the printer,modem,cassette switch is removed and is controlled by software. This is all fine and i see how it works but the 630 board is addressed at f7xx . the serial port is f7a0, the pia at f780 etc. i wonder if they supplied a new rom with the 630 or? anybody have any theory's

I made a small run of boards if anyone is interested and have some a-15's to go with it, send me PM if you want any and i will list the rest on ebay.

Happy new Year.

This is a great project! Have you ever documented the workflow and tools you use to produce replica boards?
