Downloading Files

4GB doesn’t sound like a lot, but it’s an incredible amount on the Commodore 128   A disk side on the average Commodore disk is 664 blocks.  4GB is roughly 32 million blocks.   Particles! has a 4GB CMD drive, which as of 2021, is about at its limit.   We support files for the C64, 128, Vic-20, GEOS, CP/M, PET and the+4/16 family.  Most files are in Zipcode format or straight PRGs so you can download straight to your computer.

How Do I Download?

If you’re not from the before time, it’s a bit tricky to understand how to download files using a terminal. Hopefully this quick tutorial will help.

To put it simply, computers send files using a protocol. The protocol used on the BBS has to match your terminal program so that they both know how to talk to each other.

Definition of Protocols:

The BBS supports a few types of different protocols so here’s a quick overview of them and their advantages/disadvantages.

Xmodem – The simplest protocol there is. It is inefficient but it works. It can send a single file at a time, and almost every terminal program in history supports it.

Xmodem CRC – Like Xmodem but with with improved error checking. Only some terminals use this version.

Xmodem 1K – Like Xmodem, but sends in 1K chunks at a time. Only some terminals use this version.

Ymodem – Like Xmodem, but can send in batches and has better error checking. Most modern terminal programs support this.

Punter – The defacto standard for Commodore computers. Can only send a single file at a time.

Multi-Punter – The defacto standard for Commodore computers. Can send multiple files in a batch.
