#zimodem — Public Fediverse posts

At the end, all will fit in this enclosure (there was an adsl filter inside). I made some holes for the usb and the reset button. The front hole contained two rj11 sockets, I cut the central divisor and obtained a hole the perfect size for the #uart to #rs232 #db9 connector.
Most of my #retrocomputing gear has the old #db25 connector, so I'll need an adapter anyway...

#zimodem #wifi #modem #hayes

I'm going to build a #wifi #serial #modem for my #amstrad PPC640. Something like #theoldnet 's wifi modem, but I'll use #zimodem on an #esp8266 , because it worked ok with my #commodore64 and now I have some experience with it...
The idea is having the esp emulate an #hayes modem on the #UART pins and convert it to rs232 using a #max3232 module.
I also will need to solder a 9 to 25 pin #rs232 adapter, because I absolutely don't remember where mine is (used last time a couple of home moves ago... 😅)

I built myself a tiny #wifi #modem for the #commodore64 . It uses an #esp8266 to emulate an #hayes modem using the #Zimodem firmware.
I made a couple of changes to the design found online, namely added a capacitor on the power rail (because the Commodore provides 100mAh but the ESP can have a higher transients up to 200mAh) and this one: https://www.valoroso.it/modifica-al-modem-wifi-per-commodore-64/
Now going to double-check every connection with the tester before trying it on the Commodore.
