mTCP NetDrive Undo/GoBack (updated)

(Set your video quality to HD to see the text clearly.)
Have you ever deleted a file that was difficult to recover or accidently corrupted your hard drive? Recovering from those things can be a royal pain.
mTCP NetDrive now supports journaled drive images, so that you can basically "undo" your way back out of a problem. Everything is controlled from the DOS side, allowing you to recover from mistakes corruption in seconds.
See www.brutman.com/mTCP/mTCP_NetDrive.html for the downloads and a link to the documentation.

(Set your video playback to 720 to make the text easier to read) (Hey Al - better quality and with voice!) This is a preview of an "undo/go back" feature I'm adding to mTCP NetDrive. Right from DOS you'll be able to set checkpoint marks on a network drive, change things (and possibly mess them up), and then jump backward to a checkpoint mark undoing the intervening changes. The feature is imple...

(Set your playback settings to 720p to make the text readable.) (2024-02-19 Update - the newest version of the DOS device driver adds support for multiple network drives. Now you can add up to 24 drives, 2 GB each!) Three months ago I demonstrated a project that I was working on. Since then I've added a lot to it and formally released the first version of it so I figured it was time to create a...

My latest project is a virtual network hard drive for DOS. I made a lot of progress on it recently and last night it worked for the first time as a hard drive so I figured I'd record a small demonstration video. There is still a lot of work to do but I'm really excited about it The server is a Go program that will run under Windows or Linux. It uses IP and UDP, so no special permissions or pack...

mTCP Telnet with RLE Graphics

Переглядів 5472 роки тому

I was reading about Compuserve recently and how they pioneered online graphics. Before GIF they used RLE, which is a nearly forgotten standard now. What is an RLE? It is a 256x192 black and white image encoded using run length encoding to cut the file size down a little bit. These could be downloaded from Compuserve and they were often passed around on BBSs. I've used the ones I downloaded in 1...

Hard drive voice coil motor demonstration

Переглядів 5 тис.3 роки тому

(Turn on HD video if you can ...) Hard drives have been using voice coil motors to position the read and write heads for decades now, but it all seems like magic. Here I demonstrate how a hard drive uses varying amounts of current on the voice coil motor to move the actuator across the platters. A hard drive makes scheduling decisions, deciding how far and how fast the heads need to be moved to...

Listening to hard drive noises with an electromagnetic pickup coil

Переглядів 5723 роки тому

"Ran when last parked" (pun intended) Magnetic hard drives make plenty of noises and you can usually tell what one is doing by the noise it makes. An old "telephone listener" device (an electromagnetic pickup coil with an amplifier) can be used to hear the spindle motor, voice coil, and other electronics in a way that your human ears can't. Listen to the difference between a healthy Maxtor hard...

(Be sure to view this in high definition to clearly see the lights!) This is a demonstration of an IBM 5181 Compact Printer with the RS232 signaling visible using an RS232 breakout box. The printer is run by an embedded CPU that has a total of 4K of firmware and just 2176 bytes of RAM. The breakout box shows you some of how the RS232 signaling works, including the printer using the Clear to Sen...

2020-01-22 : An updated version of this video can be found at ua-cam.com/video/bI5eb7tRA0U/v-deo.html . A quick demonstration of the IBM Compact Printer from 1984 printing a Compuserve RLE graphic. The printer was a low-cost thermal printer designed for the PCjr. As the PCjr did not have a standard serial port, the printer uses a serial interface with the special rectangular Berg connector runn...
