The machine has been featured here before but it has achieved a fun milestone: more than 1,000 hours of continuous runtime without restarting the software, rebooting, etc. See the stats at http://brutmanlabs.org/status . T

It runs on anything from an 8088 to an emulated virtual machine. Read the manual ... It's all explained.

Oh, I understood - I've been a professional programmer for close to 30 years, and I've done a lot of operating systems work. On this platform you have the burden of ensuring that the C runtime is thread safe, or putting locks arou

I discovered NCSA Telnet late, after it was obsolete, but it inspired me greatly. I still have not looked at the source code, but it is tucked away somewhere.

Each program is linked against a TCP/IP library. #defines control what parts each program gets, depending on what it needs. The DOS TSR approach would make TCP/IP a common service for DOS programs. I went with the library approa

I use the 3C503 in a lot of machines. It is not a great performer, but it is well supported and solid. And it is an 8 bit card, which is handy for the older PC and XT class machines. Other notable cards for older machines include the NE10

Probably not .. that is a diminishing returns kind of thing. If I'm the only user and there are not a lot of programs that need it, it's not worth the effort. What I have now can best be described as cooperative multitasking wit

Ouch - I thought I had it and I missed it. I'll email you a patched version.

For those of you missing context, mTCP is a TCP/IP library and some of the more common applications. It runs on anything from an old 41 year old IBM PC up to emulated virtual machines. Applications include fresh implementations of a D

My jokes don't always land well. I'll consider this a success. I prefer to look at DOS as "stable."

Thanks. It's still going, now at 530 hours. The fan noise is getting irritating. :)

There was a news item recently featuring somebody running an old PC clone as a web server. I wanted to post a follow-up showing a low-end machine with a more full-featured web site. The machine is an IBM PCjr which was introduced in 1983.

Direct link to the status page: http://brutmanlabs.org/status . The content is reasonable for retro-computing. The numbers on the status page going up are priceless. :)

For the record, the machine is running the mTCP web server: http://www.brutman.com/mTCP/mTCP_HTTPServ.html I wrote it back in 2014 and I've hosted brutman.com on it at times. My usual machine to run it on for tor

I was a little surprised by that too. It is definitely calling itself stratum 1, which is strictly defined to be the computer with the high precision device directly attached to it. Keep in mind though that strata and accuracy are two diff

This particular machine was the victim of some cost cutting, so there is no RI line. Data Carrier Detect is available and it is usually used for this. (I got my wiring inspiration from other projects.)
