Altair 8800 connect to the internet ¿?

[mpastor]

In this website we can find the altair connected to internet. this is possible?

can I transmit a message from one to another altair?

Greetings.

You could transfer files (containing a message!) between two Altairs using XMODEM, KERMIT, etc.

I'm the owner of that clone on the internet.

I use a small linux computer to do this and a program that listen on a TCP port dans transfer everything back and forth to the serial port of the linux to the Serial port of the altair.

Mike helped me making a boot disk on the altair that presents a menu.

Nice, can you perform a reset remotely as well?

No!

My Altair and Altair Clone are connected to the internet using a GW312 Serial to Ethernet Server. The server can use simple Telnet or Telnet COM Port Control RFC 2217.

Mike Douglas ported BYE.ASM and XMODEM.ASM to use Altair 2SIO port 2 with CTS enabled. BYE & XMODEM for a simple Remote CP/M (RCP/M) that can be operated remotely using Telnet. The RCP/M can load a program, for example a BBS program.

What would be indeed interesting is to "link" all our altair(clones) together using similar means, some kind of altairnet, with where a common "chatroom" exists and is shared on freenode as well and perhaps a way to share files.

The "gateway" between altair and internet doesn't have to speak tcp/ip to the altair of course, maybe some kermit-like protocol.

I am all in for an "AltairNet"

hey I would love an altairnet

You can also use a WiModem to connect to the Internet. The WiModem is a microcontroller with an RS-232 interface, and it's very useful on systems like the Altair Clone. I've started using one, since it lets me connect to the Altair from across the room, and I can leave the system on my dresser, where it lives these days.

I use this unit by Jim Drew:

and a 3D printed case from COREi64

To make this work, you do need a couple of additional components. Since the Altair is wired as a DCE device (like a modem), it needs a male-male DB25 cable and a null modem adapter. It also needs 5v power. Rather than use an external power adapter, I got a small USB regulator. It was originally intended to hook up a Raspberry Pi, but it also works for the WiModem.

here's an example:

You can also use the WiModem on the second serial port for dialing out to other systems... it acts just like a Hayes modem from back in the day; you can connect to other nodes with the ATD command, and you can answer an incoming call with ATA. This makes it nearly 100% compatible with legacy terminal software. The only software that doesn't work is software that tries to be too smart and filter text out of the dial string (Telemate did this; it converted letters to their telephone keypad numeric equivelant.)
