Retro Challenge 2019/03

The Retro Challenge is a one-month long excuse to do cool stuff with old computers and blog about it (vaguely wrapped up as a competition).

In 2017 I created the RetroMatic 2000 as my entry.

In 2018 I tried to restore two Osborne 1 portable computers. One restoration was completely successful, but with the other I couldn’t narrow down the problem in the disk controller as I lacked sufficient test equipment.

This March I’ll be doing a light-weight entry to the Retro Challenge as I don’t have too much time available.

Osborne Restoration part 16: transferring CPM software

Now my Osborne 1 is working well, it’s time to transfer some software onto it.

I have a handful of disks that came with it (just business software), but there is a whole wealth of CPM software out there, if only I can get it onto the machine in a format it can read.

Today’s task is to find a workflow that enables me to download CPM software from the internet, and easily load it onto the Osborne.
