Nils M HolmA few weeks ago I wondered what it takes to turn a small LISP-1 into a LISP-2. Turns out it takes just a few hours to get most things right, then some days to iron out a few subtleties, and then a couple of weeks to polish it into a piece of art.

mbbrutmanComing soon ... a utility to make swapping active partitions easier.On my PCjr I like to switch between DOS 3.3 and DOS 5, while keeping the drive letters in the extended partition the same. To do that you have to mark the new partition active, but also hide the old partition. FDISK doesn't allow that.Other tools exist but they are often not small machine friendly. I wrote a similar utility years ago but I lost the source code, so here it is recreated and enhanced.<a href="https://mastodon.sdf.org/tags/retrocomputing" class="mention hashtag" rel="nofollow noopener" target="_blank">#retrocomputing</a> <a href="https://mastodon.sdf.org/tags/dos" class="mention hashtag" rel="nofollow noopener" target="_blank">#dos</a>
