#floppy

Hello fellow #floppy fans! Through some fiddling and optimisation I've freed up about 180KB of space on http://floppy.museum and need something to fill it with.

Since my brain is pretty much empty at the moment, I would be very grateful for any ideas the Fediverse could offer. Some ground rules:

  • It needs to fit in the space given (duh!)
  • It needs to be relevant to floppies and/or #retrocomputing
  • It can be software (yet another service), in which case it must run under #MSDOS on a 286, and should have moderate memory requirements (some EMS and XMS is OK, but at most 380KB conventional..)
  • It can be art (but don't expect me to create any, so the license must permit this usage)
  • Should not require modern browsers of hardware to access/enjoy

Ideas floated so far:

  • Gopher server (problem: how to convert html to gopher pages; yes I've tried, no it's not easy)
  • Rmenu (a telnet server allowing running of commands on the machine)
  • Samantha Fox GIFs

Spread the word and give me ideas! The sillier the better!

Trying to optimise http://floppy.museum for (even) older browsers. Some of the issues I'm trying to solve include utf8-to-latin1 translation (the original HTML has some silly double- and triple-byte characters), and variations of JPEG that simply aren't understood.

Turns out Netscape 2.02 is too easy, so in this picture is IBM WebExplorer v1.1h running on OS/2 Warp Connect. Using the magic "work area" feature of folders (mark a folder as a work area to have the OS manage objects within it as a kind of unit), I can open several windows at once. True multi-process browsing 😉

I wonder if a sufficiently large #RAID 0 array of #floppy drives could match the throughput of an #SSD, and if so, how many drives it would take.

Let's see…

The Crucial T705 does sequential IO at 13387 MB/s, or 109666304 kbps. A floppy drive can do sequential IO at 250 kbps.

So, an array of 438665 floppy drives should be about the same speed, and would store about 602 GB. Not bad.

Now, how do I connect 438665 floppy drives to one computer? 🤔

Niveau configuration cela donne quelque chose comme ça : à gauche le fichier IMG.CFG à déposer sur la clé USB du #Gotek , et à droite le fichier spécifiant le format pour la #greaseweazel , à utiliser dans la commande de lecture de disquette.
Le fichier image en lui même contient juste le contenu de tous les secteurs à la suite sans aucune métadonnée.

My horribly old #desktop #PC is finally starting to die. Currently running a backup (using #zfs send/recv) to my server of one important local dataset.

Now I started looking for new hardware and to my surprise found a "modern" mainboard with a "real" parallel port (internal header, certainly good enough). This really helps with my retro hobby (#C64), years ago I soldered a simple interface cable that allows using a 1541 floppy on the PC, I even ported the #opencbm driver for that from #Linux to #FreeBSD. Without a parallel port, you'd need some complex USB interface instead including a microcontroller and "tons of shit", while the cable for the parallel port basically consists of a few diodes.

Now I wonder one thing: I'd also love to have a #FDC (#floppy drive controller) again. Is there any modern board coming with THAT as well or should I just forget about it?

#retrocomputing question: I'm trying to boot my #macintosh #powerbook 170 from #floppy . So i used a #linux machine with #dd to write a known good #system7 disk image onto a known good #floppydisk .
But dd exits reporting an i/o error while writing. Note that I can create working #msdos floppy with the same drive and same floppy. Also tried other floppies, same error and every time at the same place (44kb from the start).
As expected, the mac won't boot, but for a little while I see the happy mac icon, so it seems the first part of the disk is correct.
Is there any mac-specific parameter to pass to dd? Any other hints?

Games That I Missed

Back at the end of October, I got around to opening up my 3.5-inch #floppy drive for my Apple #IIgs (mastodon.social/@GamesMissed/1), and found that the likely suspect was the correct one: a cogwheel in the eject mechanism was crumbling and had already tossed some teeth.

I ordered replacement gears, made the swap, and the drive is working perfectly now. This lets me use software like Print Shop, which won't run without a floppy disk present.
