Need one day when archiving old floppies: [WayBack] GitHub – bbbradsmith/flompy: DOS floppy disk dumper
Via: [WayBack] Brad Smith on Twitter: “So I wrote a floppy disk dumper program for DOS. I dunno if this is really a very useful thing, but it’s open-source at least! 💾⚡🖥 “
Full thread at [WayBack] Thread by @bbbradsmith: “Hrm… why doesn’t the floppy controller status register have its non-DMA bit set, even though I’ve used a specify command to set it… and […]”:

Editing [WayBack] What is a Delphi DCU file? – Stack Overflow for more historic correctness and adding links prompted me to archive some older material and search for some more, basically because while historically very relevant, link rot makes a lot of that stuff harder and harder to find.
The legendary full page colour advert published in the 12th 1983 issue of Byte Magazine on page 456 is at the bottom of this post (Many BYTE magaine issues have been archived at https://archive.org/details/byte-magazine).
The smaller version below is from WayBack: Sip from the Firehose : November 2008 marks the 25th anniversary of Turbo Pascal v1.0! (this article is not available on the Embarcadero or Idera site any more).
I also included more adverts in reverse chronological order at the end:
The last two via [WayBack] saundby.com: Software for the Ampro Little Board.

Reminder to self: see if I ever can resurrect my old BBS and FidoNet node that was based on at least:
Maybe a good place to start: [WayBack] Running BBS Door Games on Windows 10 with GameSrv, DOSBox, plus telnet fun with WSL – Scott Hanselman
I already wrote a few times about me being on Fidonet, and BITNET in the late 1980s:
A few email addresses I have been using in that era:
A tag-line from me in that era (I blanked out the phone number as it now belongs to someone else):

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): [WayBack] The Throttle homepage. Slow that machine down!
Downloads:
- 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.
