Over the past 18 months, a number of Sol-20 happenings have accumulated in my email inbox and here are some overdue updates.

Nino Porcino has written (in 2021!) a Tetris game for the Sol-20.
Michael Gardi has written a Sol-20 emulator, written in Python & the pygame library. I've written some brief notes on installing and running his emulator.
The great Bitsavers website added a new directory with some great Processor Technology manuals and brochures (see the subdirectories there too)
I cleaned up the links page to remove some dead links and change the URLs of a few pages which have moved.

Dave from osiweb.org has designed a number of replacement parts for Sol-20 computers. Go to the top entry on the links page for all the details.

Paolo Binotti contributed three more manual scans, available on the manuals page. Thank you, Paolo!
