13Leader Posted February 25, 2020 Share Posted February 25, 2020 (edited) Just interest in what people use to set-up and/or connect 8-bit Atari computers to the internet. For BBSing, telnet - that kinda thing. This is my set-up My 130 XE --> 850 interface (thanks ebay!) --> a home brew null modem (to get the pins to std RS-232) --> RS-232 to usb cable (thanks Amazon!) --> Raspberry Pi 3b (thanks again Amazon) --> the internet --> BBS's The Details 1- Parts can all be purchased on Amazon for under $100.00. Parts Lists: - 2 x DB9 connector to create a null modem. 1 Make and 1 Femaie - USB 2.0 to RS232 Male DB9 Serial Converter Cable with PL2303 Chipset - Raspberry Pi 3 3b 4, etc.. 2- Build a null modem. The wiring/pins layout can be found here. The 850 pins are not really std RS-232 but the link below will help build a number of null modem types. http://atari.fox-1.nl/atari-400-800-xl-xe/400-800-xl-xe-tools/null-modem-cable-wiring/ 3- Raspberry Pi software I use to emulate a modem can be found here. The readme.md has good installation instructions, It supports telnet, ssh, xmodem and ymodem protocols https://github.com/pjones1063/Atari-usbModem 4- To connect to a bbs --> atd hostname port other commands the software supports: ? --> help atz --> Clear & Display Menu atd (hostname) (port) --> TCP connect to host bbs (hostname) (port) --> TCP connect to host cls --> Clear & Display Menu lsi --> list inbound folder lso --> list outbound folder ssh (user@hostname) --> ssh to host ysend --> YMODEM batch dowload yrecv --> YMODEM batch upload xsend (filename) --> XMODEM dowload xrecv (filename) --> XMODEM upload timer --> set on/off inactive timer I also use the Pi to run RespeQt. I just rdp into the Pi and select whatever .atr image I want to run! Edited February 25, 2020 by 13Leader 1 Quote Link to comment Share on other sites More sharing options...
tuf Posted February 25, 2020 Share Posted February 25, 2020 Cool write-up. I use a similar setup but instead of a pi I use a winmodem232 with an 850 or the occasional MIO. Cool idea about using the pi for respeqt. Would be cool if there was a way to select the atrs from the Atari. Quote Link to comment Share on other sites More sharing options...

Would be cool if there was a way to select the atrs from the Atari. It actually does. 8-bit screen prints below. You can check it out in the thread here: or see it at https://sourceforge.net/projects/respeqt/ and here https://13leader.net And of course ebiguy's fork https://github.com/ebiguy/RespeQt You would have to build it from source on the Pi but that's not too bad.

Very cool. How do you make the device telnet to a BBS? I have never used (or actually seen) a Lantronix MSS100. Quote Link to comment Share on other sites More sharing options...
13Leader Posted February 25, 2020 Author Share Posted February 25, 2020 (edited) This is the null modem I did. I can say it works very well with the 850 and RS232 to USB cable I also use the Pi to do the same RS-232 connection to my 1040 STe. Same idea as above just with another RS-232 to USB cable - less the 850 and null modem. I run two instances of that modem emulation software above - 1 for each cable/computer. Of course I have a 3rd USB on the Pi for my SIO2PC cable for RespeQt. Edited February 25, 2020 by 13Leader 1 Quote Link to comment Share on other sites More sharing options...

I have never used (or actually seen) a Lantronix MSS100. The MSS100 has a DHCP client in its firmware. It gets an IP address from my LAN and when set to Modem emulation mode, can accept dotted-quad IP addresses or translate real domain names to IP addresses. So from my Atari’s terminal program (usually BobTerm is ICE-T) I issue a standard Hayes ATDT command but instead of a phone number, I use the address of the Telnet server I’m trying to reach.

a8isa1 Posted February 25, 2020 Share Posted February 25, 2020 (edited) I just used the following example for building a DIY wifi modem as a guide and built my own. https://1200baud.wordpress.com/2017/03/04/build-your-own-9600-baud-c64-wifi-modem-for-20/ No need for RS232 conversion as I connected it directly to SIO and used an R-Verter driver. However, add the RS232 converter and the wifi modem can easily be connected to an 850. Later I switched to Bo Zimmerman's Zimodem firmware. Just personal preference. Paul Rickards' Strikelink firmware (from above) worked perfectly well. And now I'm anxiously waiting for the ##Fujinet project to be completed I'm using older ESP8266 based Nodemcu v0.9 development boards for *play testing* all 3 projects above but at least the latter two can be ESP32 based. -SteveS Edited February 25, 2020 by a8isa1 Quote Link to comment Share on other sites More sharing options...
pusakat Posted March 6, 2020 Share Posted March 6, 2020 How would you do this with RespeQt and an SIO2PC-USB cable? Quote Link to comment Share on other sites More sharing options...

Kyle22 Posted March 7, 2020 Share Posted March 7, 2020 I use Atari800 -> Atari 850 -> Atari CX-87 Modem cable -> Lantronix UDS-10. The only bad thing is it only takes IP addresses. It has no DNS resolution. Works great for the BBS. Quote Link to comment Share on other sites More sharing options...
