FWIW you probably don't need a USB serial port, or a RS232 converter at all; you could just pick the TTL serial signals off the commodore port and plug them into the TTL serial port on the Raspberry Pi 23- or 40-pin expansion slot (pins 8, 9, and 10 are TX, ground, and RX.). Remove the tty on /dev/ttyAMA0 from the init config and you can use /dev/ttyAMA0 as your built-in Pi serial port.

#42Come on guys... C64 all of the things! Some of the comments here are ridiculously negative or taking away from the fact that Jeff has done something cool here. Good stuff, Jeff! Keep on doing stuff like this and don't listen to the hate/negative comments.
Thanks! It's just a fun project, so of course there are lots of ways to improve it!
I found writing 6502 assembly code is strangely comfortable once you get over the initial face-palm moments ;)

Thanks, yeah, I will try this - I followed a design for a c64-pc cable without considering that the Pi probably had serial port pins.

#44Does it have to be used with a Raspberry Pi? If you have a Wifi Modem for C64, would the Slack client still work?
You would need to replace the rs232 code with code to talk to the Wifi modem. You would need to deal with websocket handling and JSON parsing.
Doable, for sure, but would be significant work (depending on the richness of the API provided by wifi modem)

#46Should have just stuck with IRC :(
Except many companies (presumably including Jeff Harris') use Slack. This allows him to Slack on his machine and not create some new mandate at his work or with his clients just to message people.
I think this is fabulous ingenuity, useful fun, and the eccentricity doesn't rock any boats along the way.

#47Earlier quoted context omitted.
The original version? Not even close. (: TCP/IP was a thing when the C64 came out, but it was one of many competing networking standards, and it wasn't even the favorite to win.
Fascinating - what was favored to win at the time?
IPX and NetBIOS (which MSFT called NetBUI) were introduced after the C64 came out.
I would say DECnet phase IV or IBM's SNA were the biggest contenders, along with X.25.

#48but why? (Pls, don't reply: for the glory of satan)
my question was serious, i don't see why i should get down vote for this.
i'm actually curious to understand what's the reason to build this. it may be fun, but once it's built you trow it away. it's like baking a cake and don't eat it.

#49> I connected the Userport to a Raspberry Pi with a artisanal, locally sourced, homemade cable with the UserPort connector on one end
The writing in the blog post is nearly as awesome as the project itself.
