Brilliant video Tim. I managed to snag a lovely condition C16 a few years ago from F/Book/MarketPlace which had a blown internal fuse and a faulty power supply plug. After replacing the internal fuse with a brand new one and fixing the P/Supplies faulty plug the machine powered up perfect. I then researched on Google to add the 64k RAM upgrade, which i did mine with an On-Off inline switch (so i can still switch back to the standered 16k (as there are a few C16 games that refuse to run correctly in 64k mode (Rockman is just one of these games). I also added an internal SD2IEC Micro SD card board, added heat sinks to the main IC chips and it works flawless. I last owned a C16 in the late 1980's/early 1990's and spent many joyfull and happy hours playing Rockman, Bandits at Zero, Booty and Blagger. For me the C16 is still such a thing of pure beauty and nostalgia.
Great, thank you. Yes, using the board to align the sockets does help. Dual wipe sockets are more forgiving for alignment, but the turned pins ones seem a better contact.
Wow, I thought that would have been in a wedge case and not a bread bin. I didn't know the made a C-16 like that. I guess the smaller ram chips were a lot cheaper back in the days of lore.
If you ask me, this is a super ugly update. (Sorry to say.) It is way tidier to replace the existing 16KB DRAMs with 64KB DRAMs and run the wires on the bottom side of the board, if you run them in horizontal/vertical lines, with a drop of glue, this looks super tidy. For the cutting the trace under U7 I did drill a tiny hole, this causes less scars than desoldering U7.
