Not 100% sure about c64, but the add on tape drives for the BBC micro had a control line for stopping and starting the tape automatically.


( Rem being remote control )

at least the one i had was fully manual



youd also save stuff by hitting record when the program prompted you, or before hitting return on your own SAVE command

QuickTime was extremely widely licensed, and its concepts and file format underly video today

I think the browser plug-in was even up there with Flash and Java for how widely distributed it was

who knows why nobody made something like YouTube with it instead of Flash, maybe Flash let YouTube obfuscate a bit or something
Wasn't quicktime a lot less flexible in terms of being able to program it to work however you wanted to integrate it into your site?

this was possible and worked well with QuickTime for nearly a decade before YouTube was introduced

the “fast start” movie layout that puts all chunk description atoms up front and orders them was first created to use with CD-ROM, which was originally only about three times as fast as 56K dialup; this let a movie play smoothly while being retrieved, as long as it didn’t need more bits/second than were coming down (possibly after some preroll)

then Apple not only added RTSP support to QuickTime in the mid-1990s, but also wrote an RTSP server that ran on UNIX and made it Open Source in like 1998-99 and could deliver tons of movies at once with the ability for users to scrub through them, jump anywhere, etc.

YouTube doing it all with Flash was a big step backwards

56k modems only got 5 kbyte/s vs 150 kbyte/s from 1x cdrom

its kindof annoying when say a forum has external links open in the same tab/window by default (ie no href target="_new" or whatever its called) so you have to remember to do that yourself. it would suck if you always had to do it

hey when someone had a tape drive backup, what was the benefit? density back then?

and hows it work? did it manage its own start/stop?


tape drives like c64 intrigue me I guess because the computer has no control over the data coming in. I suppose it was slow.

tape backups are still used all over the place for archival purposes. i got IT to restore tape backups of things (usually the design stuff is archived after a product is released) couple times at intel and the economist had a good article about it recently:

https://www.economist.com/science-and-technology/2020/12/15/magnetic-tape-has-a-surprisingly-promising-future

quote:

Demand for more storage will certainly be there. Estimates suggest that four times more data will be generated in 2025 than in 2019. In the part of the data-storage market where tape currently reigns supreme, it is likely to remain so for a while.

The biggest threat to tape comes from the flash-drive technology used in sd cards and usb sticks. Flash relies on a flow of electrons through transistors, rather than on magnetised particles read by mechanical components, so it is capable of better data densities even than hard disks. Lack of moving parts also makes such solid-state devices faster at writing and retrieving information. Flash drives are, however, more costly than magnetic storage and do not last as long. This makes them ten times more expensive per byte per year of storage than hard disks, and nearly 50 times more expensive than tape. They are therefore too dear to use for anything but the most important jewels in the data vault. Until that changes, the reel is likely to continue.

echinopsis posted:

and hows it work? did it manage its own start/stop?

depends on the era, but generally tape drives work in terms of “files” made up of consistently-sized blocks of data—512 bytes typically, though most modern tape systems support varying the size as long as it’s consistent within a file—with “marks” between them made up blocks of repeated data (e.g. a mark might be two blocks of zeros)

the drive does manage its own start/stop, the commands it responds to are typically things like “read 128 blocks of 512 bytes” and “write these 17 blocks of 8192 bytes”

having the marks between files does allow some more intelligent drives to support seeking back and forth between files, similar to a disk; in the 1970s and early 1980s there were even some systems that used small tapes for random-access storage instead of sequential-access:

  • HP DC100 on the HP 9825
  • DECtape II (which used the same tapes that were developed for HP DC100, but with DEC-specific formatting—in that the tape had to be formatted to be used, unlike an HP DC100)
  • Coleco Adam (yes really)

echinopsis posted:

also did ram doublers or doublespace actually do anything at all

Connectix RAMdoubler worked exactly as advertised, it replaced the system pager with one that evicted pages from the working set by compressing them and sending them to another area of memory, and only writing them to disk if that was also filling up

you need a certain level of CPU performance for this to be reasonable because compressing pages and managing the compressed page area has to be fast, but once it is you can effectively get way better performance out of a virtual memory system

RAMdoubler also made a few other changes to how the operating system managed application and OS memory so as to increase sharing, reduce overhead, and allow memory partitions allocated to applications to be temporarily used for other data without affecting the applications they belonged to

all this means that I can install RAMdoubler on a Mac with a 68030, 68040, or PowerPC CPU and it really is like installing more RAM in it and only software that does hardcore low-level memory management (like older versions of Macintosh Common Lisp) even notices
