Here's a small, interactive demo that allows you to move a softsprite across a screen in 160x100 resolution (64 kB VRAM required).

You cannot view this attachment.

Use keys IJKL to move the ghost, X exits the program.
You can also list the sourcecode, which shows that the main loop is a regular basic program.

This uses the VDC-Basic extension which focuses on leveraging on the hardware capabilities of the VDC-Chip (block copy and block fill).
In 160x100, one byte holds two pixels.
Fully transparent bytes are skipped from block copy.
Bytes with one transparent pixel require a slow OR operation.

Still, drawing the softsprite only takes about 2 jiffies at 2 MHz.
This is using double buffering, so there's no flicker.

Looking at this, I think the C128 could have been capable of running DOS ports that never made it to the C64. Or ports that really were beyond the C64's strengths (eg Ultima VI)

The station wagon is packed.  The hotels are booked.  The room is ready for even more rare Commodore and Amiga equipment on set-up day this Friday.  The PaCommEx website has been updated again on the Exhibits page and the Guests and Presentations page.  Come join us at the show next Saturday and Sunday!  We will be at

Despite the permanent closing of the Living Computers: Museum + Labs last year, there is another Seattle area museum to take its place – the Interim Computer Museum. A non-profit charity in partnership with the membership organization SDF Public Access UNIX System, Inc., the ICM counts on museum members/donors/sponsors in order to stay funded. The ICM boasts a collection of computers ranging from tube-type, analog computers used in corporations and universities to personal computers of the 1990's.


The museum is open by appointment on Sunday and Monday. Members get extra privileges at the museum, such as access to special members-only functions. For more information on the Interim Computer Museum, go to

P.S. Of course my main interest at the ICM would be the Commodore 8-bit and Amiga computers!

Timing table for every PET command

Just double-checked. It doesn't appear to have the Commodore brown.  My comparison was the screenshot of the BIT-C-128 VideoDac at https://www.bit-c128.com/
