Wifi RS232 Modem in 2025?

[James Harland]

Hi everyone,

So I watched this video and immediately became enamoured with the idea of browsing BBS via an old terminal like this over WiFi. I have an AT&T 715-4425 terminal, and would love to try this myself.

It doesn't seem to be so straightforward to get hold of one of these WiFI RS232 modems though. Several of the places that did supply them seem to have sold out. I have contacted 8bit_bruno over ebay, who might be the original creator of them I'm not sure.

I know that the circuit plans are open source, but my electronics is not up to just following a circult diagram to build something (yet). I wonder if there are any tutorials out there, or if anyone made a PCB which I could add the parts to. I live in Kazakhstan, so ordering lots of parts from AliExpress might be more reasonable than getting a unit shipped from Italy.

Would be great to hear of people's experience of the WiFi RS232 modem, especially if you managed to get hold of one recently.

Thanks,

James

I have bought WiFi modem (https://www.tindie.com/products/theoldnet/rs232-serial-wifi-modem-for-vintage-computers-v4/) primarily for browsing internet BBS's, but I have found there nothing interesting for me. But now WiFi modem on my SC126 (ZPM3, combination of CP/M 3 and Z-system) work as "network card". I have wrote program for set RTC, simple mail program, gopher client and series of programs for file transfer to/from home NAS via WebDAV protocol (http://www.chstercius.cz/cpm/). At this time is WiFi modem very important periferal for me.
