Discobolus

Here is Discobolus for anyone to play with.

Discobolus is a tiny module to show disc read and write activity at the pointer.

Many modern disc options, such as SD cards or SSDs, do not have disc activity LEDs. Discobolus is a small compensation for that, but is by no means a replacement.

A selection of disc operations causes Discobolus to display the hourglass pointer for a short period. This period is not related to the time taken for the operation to complete.

The hourglass defaults to red for reading and orange for writing operations with a period of 20 centi-seconds, but these can be changed with *Discobolus.

Discobolus can be downloaded from:

Seems to be working fine, and is much less ‘intrusive’. The continual pulsing when an image is open in Thump appears to have gone. I’ll leave it running to see how it goes.

The reason is probably that Discobolus now ignores all reading and writing of meta-data. There is a lot of that going on.

There is a new version at:

This has a default grey outline, which can be switched off, and the *Discobolus parameters can be applied directly to a *RMLoad Discobolus command.
