There is also a alternative option of building a SCART cable and using a
SCART to HDMI box for this. For those that have gone this route is
probably one of the easier routes.
I myself use a RGB to S-Video adapter board that Ed Snider put together so
I can use my video capture board for YouTubing my CoCo's. As most HDMI
capture devices have a 2 to 4 second encode time I opted to go with
something that had little to no processing time so I could see what I was
playing or doing on the CoCo through my capture device, but that is my

Well the MFM drives is true you can't get new for. As far as the IDE
there are places that still sell new ones, but might be a little big for
We do have some alternate devices for using (micro)SD(HC) cards now. The
SuperIDE uses both IDE and CompactFlash drives and you can get microSD(HC)
to CompactFlash adapters very easily.
As other people have stated you can also use the IDE (PATA) to SATA
adapters for using a SATA drive on a IDE(PATA) controller.
Also for the older retro systems as far as SCSI goes there is also the
SCSI2SD project that allows you to use a microSD(HC) card in place of the
older SCSI hard drives. This is what I am using on my MM/1.

As far as printers yes that can be a interesting challenge, but multiple
ways to get around that. Some of the new receipt printers still have a
serial port on them.
As some have stated there is also DriveWire when under OS-9 to send your
printer output from the CoCo to the system connected to the printer.
There are also serial to TCP bridges as well that you could use. Or even
build your own Raspberry Pi cups box and using a USB RS232-serial adapter
connected to the bitbanger port, or MAX232 chip to convert the TTL signals
on the onboard 2 pin serial to RS232-serial and capturing the bitbanger
output and sending it out cups to print.
There are many options.
