The Throttle homepage. Slow that machine down!

Posted by jpluimers on 2020/01/06

Cool tool if you have industrial machinery that uses DOS and needs a slowdown on modern hardware (because for instance your serial communications program is running way too fast): [WayBackThe Throttle homepage. Slow that machine down!

  • Q) How does throttle work?
  • A) Throttle enables power management bits in the chipset to control CPU clock. Any chipset that conforms to the ACPI (advanced configuration and power interface) specification has a means to enable and control the throttle.
    The intended purpose of these bits is to provide a means of power savings, typically utilized in notebooks or other battery powered devices.
    When the CPU is in a throttled state, it uses less power. It just so happens that a throttled CPU creates a perfect environment to emulate the performance of an older generation CPU!
  • Q) I have a chipset that supports ACPI. Why isn’t it supported in throttle?
  • A) Probably because I don’t know about it. Because the ACPI specification can be implemented in different ways by different chipset manufacturers, it’s impossible to create one generic program that works with all ACPI compliant hardware. This creates the problem of constantly updating the internal database of known hardware. So far, the biggest problem has been finding the documentation for known ACPI compliant chipsets. Adding support for them is the easy part! You may also be using an older version of throttle. Contact me for the latest.
  • Q) Can I have more speed options than just the 8 (or 16) provided?
  • A) No. Throttle provides you with as many different CPU throttling options as the chipset allows. The ACPI spec only defines 8 different modes, each one 12.5% more throttled than the previous. VIA technologies has taken the spec 1 step further and allowed for throttling on 6.25% increments, thus doubling the amount of options available, which provides for more slowdown and a finer tunability.
    If you want to run oldskool games, get a VIA motherboard!There’s nothing I can do to change the available options, and no further options will be available unless the ACPI spec changes.

Saving windows command prompt history to a file – Charlie Arehart’s ColdFusion Troubleshooting Blog

Posted by jpluimers on 2018/11/14

Dumping the command prompt history

From [WayBackSaving windows command prompt history to a file – Charlie Arehart’s ColdFusion Troubleshooting Blog:

doskey /history

gives you the command history.

Redirecting with >, >> or piping with | allows you to save this to a file or filter the output.

Found via: [WayBackHow I can export the history of my commands in Windows(7) Command Prompt? – Stack Overflow

Shells that do support persistent history

Note that the command history is not persistent. If you want that, then there are two other shells that support persistent history:

Both of these found through [WayBackwindows – Is there a global, persistent CMD history? – Server Fault.

Cool [WayBackGitHub – oldcompcz/SpaceAssault: DOS space shooter in ASCII. written in pure C using Turbo C.

You can likely compile this using this:
