Forum to discuss all matters relating to the MPC1000 and MPC2500 operating systems created by 'JJ' (all versions).

So, I've been searching the internet for hours now and I can't seem to find any way to download any other JJOS versions than form https://www7a.biglobe.ne.jp/~mpc1000/mpc2500/

In the FAQ of this thread there is a link, but I guess the website is down as I can't open the page with any browser/cpu.

The reason I ask is, I've been working on the JJOS 3 1.19 for years, and I just bought a second MPC2500 on which I would love to have the same version of JJOS.
Anyone knows a guy, site or maybe has a file somewhere? Would immensely appreciate any help... :roll:

Hey. Are you sure the version is actually JJOS 3 1.19?
I'm asking because this sounds really ancient as support for the last OS3 version 1 (1.52) ended in 2017. Current version of OS3 is 2.53. So 1.19 sounds like is at least 10 years old...

Going through a drawer of old random stuff today, I found an old hard drive that I used to backup old projects etc from many moons ago. Lo and behold I've found what you are looking for on there:
