TCP/IP between OB-430 & HP-200LX
I had some time on my hands this weekend while it snowed. So I started thinking about using TCP/IP packet radio over Amateur Radios. This was back in the early 90's. We used a TCP/IP package put together by Phil Karn, KA9Q, of Bell Labs. The NOS package could run on almost any MS DOS hardware. Including on a floppy based IBM PCjr.

I had to give it a try on the HP-200lx, plus it would need a system to talk to - OB-430 would be perfect. I still have two 44. Level IP addresses (ampr.org), so used them to set it up. I connected the two through a SLIP link over the RS-232 ports. Works great.

Each system has a BBS, mailer, ftp server, pop, etc. I could send mail between the two, FTP files, etc. A lot of fun and a lot of memories.

Of course, it's just a closed network between the two computers, but it was great seeing an old-time bbs on the HP-200LX.
