    This uses the same DOS functionality that powers the logical B: drive in a single-floppy system. It's been a while since I've looked at the DOS innards, but either it just notices the two drives have the same physical drive number, or there's a flag set in the Disk Parameter Block, and you get the whole "Insert disk for drive X:" thing. It also remembers which one is currently in use.

    • @prozacgodretro
      @prozacgodretro Рік тому +1

      yep! There was some random neuron that fired off remembering that message, and that single floppy setups would use it. It made it ALMOST like you had 2 drives, but some software was hell on switching between disks.

    Did this all the time in the 90s when you needed dual 5.25" for some software but wanted to use a 3.5" for new stuff. MFM hard disk controllers were still common. You can plug your toggle switch directly place of the floppy drive jumper switches and skip the breakout board entirely. Just crimp more plugs on your cable.

  • @CaptainPiracy
    @CaptainPiracy 2 роки тому +10

    Add a button. Disk detect is just another pin on the interface. Exposing it on the same header would let you rig a momentary switch to for a disk detect anytime you want the refresh.

  • @stipuledfatcat
    @stipuledfatcat 2 роки тому +21

    For the switch you could always just make a second PCB, attached to the first one but can be snapped off or just a separate board entirely, that has hole for the switch to be soldered in and a pin header to connect the wires. That is assuming the time consuming part of making them is attaching each individual wire by hand.
    Edit: the header would have to stick out one side and the switch stick out the other side. And maybe some key or colour code for the wires/connector so no one plugs things in wrong.

    • @prozacgodretro
      @prozacgodretro Рік тому

      I was thinking something like that, but perhaps soldering the switch onto an edge, vs through hole. then the pin header would extend backwards and it would be in a nice line for mounting

  • @travispierce70

    Greaseweazle can support 3 drives at once with a flat cable. You have to jumper a unique drive select for each drive. In the software, you would then indicate drives 0,1,2 instead of A,B.

      !!! Hard to read, hard to follow (no links), hard to search for ... so please thank UA-cam for Censoring !!!
      For more info, see : glencanyon, 10 mo. ago (topic "I installed 3 floppy drives and a greaseweazle into this old SCSI enclosure. It has a 1.44MB 3.5" drive, a 360K 5.25" drive and a 1.2MB 5.25" drive."): "I used a cable with no twist.
      You have two options with the greaseweazle. You can use a standard floppy cable with the twist that supports 2 drives. The two floppy drives would need to be jumpered as DS1 - like in a standard PC configuration. From the command line using the tools, you would then indicate you are using drive A (beyond the twist) or B - the drive before the twist.
      When you use a straight cable with no twist, you can connect up to 3 devices on that single cable. You then have to jumper your floppy drives to be either DS0, DS1, or DS2. From the command line, you would indicate the drive as 0, 1, or 2. I made this cable by cutting off the twist from the cable (I just used scissors) and then added another edge connector to give me 3 connections."
      Or the Greaseweazle wiki site, "Greaseweazle Models":
      Features - Multiple Drives, supported by Model: F1 Plus, F7 Lightning Plus and V4. Previous Models not included (Nov. 2022)
      (Multiple Drives: Allows simultaneous connection to two PC, or three Shugart, drives on a single ribbon cable. Useful for cased installations.)

      I think it was more so that single drive computers could have a virtual second drive, that allowed access that appeared to be 2 drives, while only on one. I recall a faint memory of using a computer that required lots of floppy switching and seeing that message popup a lot, on some programs. And you'd be swapping between a program disk/data disk a lot

    if you used a DPTT switch you could have things as follows:
    position 1. drive 1
    position 2. emit disk change signal
    position 3. drive 2
    this way, you could spare yourself this whole disk driver stuff and dos would be told everything by hardware

    • @thedave1771
      @thedave1771 3 місяці тому

      It’s been a while but there is a dedicated pin for this, I believe it indicates 1 when a disk has changed, then drops to 0 when any other command is received.
      You’d still need to initiate some disk operation for it to notice the new disk, I think. I don’t think this tripped an interrupt, I think it expected the system to check this pin at appropriate times, but I could be wrong about this.

    On my family's Commodore PC-10 (XT clone), it had a 720k floppy as B-drive. In DOS 3.3 you could reassign the B drive from 360k to 720k with DRIVER.SYS (no fancy BIOS upgrades, mind you!). But in DOS 4.01 it gave the 720k drive the letter C instead and you had to press the Any key to continue. In DOS 5 and later, it behaved the same as in 3.3. If memory serves: DRIVER.SYS was first shipped with MS-DOS 3.2.

    How about making it the same form factor as a 3,5" drive? Lots of machines have plenty of empty 3,5" hard disk slots, so you can put it in there and maybe even accomodate even more drive cables if you want.
    Also, you would have enough space for things like relays or digital multiplexers which would allow you to select drives through some command from the host system.

    Find one of those old huge KVM switches with the physical A/B/C/D knob in a big beige box. Those switch several signals at once. If you don't want to modify the switch and you're sufficiently insane, you could make floppy-to-VGA adapters just to plug into the switch.
    There are also quite cheap ICs you can get on breakout boards that do the same job. Four input signals route one pin to one of 16 other pins, bidirectionally. You would need one per signal you want to switch though.

Two, flux image a disk from the drive or three, become invisible and let you use the drive as usual. It is controlled by wi-fi and an app running on a phone.

    As far as I remember most of the floppy-drives I have ever used facilitated mounting points under the drive. Maybe it would be a solution to build a mounting bracket to screw the board underneth the bottom-most drive in the system if there is room for it. This way the cables could be rather short.
    Just an idea that occured!

  • @fortmax8370

    Part of this DOS functionality was there from the start. In a system with just one floppy drive, DOS would assign both A and B to that drive. It probably couldn't be configured manually until PC-DOS 3.2, as that's the first version with driver.sys

    How complex is it to replicate that refresh signal which the real floppy drive sends when you take a disk out? I ask because I'm curious if it'd be possible to integrate a circuit into the switcher board that sends that signal whenever you throw the toggle switch. That would be really cool!!

    This is just simply brilliant, with emphasis on "simply"... ❤I'm in love❤... and boy-oh-boy do I feel your pain with soldering up those toggle-switches.
    - There came a point where I just began soldering pin-headers directly onto the toggle-switches and then used Dupont-patch cables. But an even better solution is to use these smaller PCB-mountable switches which is available in exactly the same variation of pins and with exactly the same functionality. Then of course solder those onto small PCBs with through-holes for pin-headers... and, you guessed it, use Dupont-patch cables in-between.
    - But I guess if you also (just like me) love to hate these old Airwolf-style toggle-switches. Then I guess similar PCBs only with holes large enough for the "pins" of those Airwolf-switches wouldn't be entirely impossible to create 🤔
    BTW. That unobtainable crimp tool you mentioned... is kind of rather easily available on AliExpress. I think I paid around $20 for mine.

      No such thing as a PC that only supports one floppy. Do you mean your cable only has one connection? Use a different cable. The PC floppy interface supports multiple floppies. Your floppy drive will have jumper switches to set drive select if your cable doesn't have a twist.

      I have an IBM motherboard that only allows you to configure one floppy drive. The BIOS will only ever report one drive to the OS as a result effectively meaning the board can only support one drive. This could be used to work around that but that board is probably later for running Win98 or XP which isn't going to be as smooth of an experience as it is with MS-DOS

      Yep, later 98 machine, only allows you to configure one drive in the BIOS.

    my current nightmare is getting the SCSCI drive I have to work with a dell pentium 1 using an interface card, only reason I accepted this machine was cause it had SCSI interface and IDE interface

      also this reminds me of having to soft reset the kaypro I have as CPM doesn't do hot swapping very well and the cache doesnt always clear so sometimes you have to I think its crtl C on the kaypros to soft reset the unit, forgetting to do this can result in disk read errors in cpm 2.2

    Surely, instead of using a switch you could just use a jumper on the pins.

    Hey, if you’re running the audio through a mid-cut filter, could you ease up on the depth a bit? Smiley face EQs are great for music, but that’s where all the intelligibility is for speech.

    this is very basic. it is mind-boggling that they dont integrate this switching feature in the first place. like seriously what were they thinking. old people developes so many interfaces thinking that theirs is the best while literally all of those interfaces are poo (thats why we dont use it anymore nowadays lmao thanks for usb).

    A heads up to help you: Having it shown in linux could help spread your idea. Also though AtariST (since it uses PC formatted floppies). As an aside, an (A500) Amiga mod would be cool. A PC (or Amiga) version via ieee1284 or parallel ports would be cool but switching partly via serial (mostly PC though, especially parallel bootable, EPP and ECP). See also Lallafa Parallel Plipbox (Amiga).

      @Mr Guru I know about that configuration and yet I was speaking of a different variety of scenarios. For example, perhaps you have heard of how the external floppy drive port can be converted to become the boot device by means of gentle alterations to the motherboard. Thereby fd1 is fd0. Then so as to save 30KB in memory (per floppy drive), a switch between floppy drives like that device is a potential method to try (similar in some ways to the video). Be mindful that having 4 floppy drives simultaneously instead of 1 means that an extra 90KB RAM is use, and yet some amiga models have only 256KB or 512KB RAM. Additionally, some software refuses to recognise drives beyond the fd0 drive. This information is to help you, kindly.

      @Mr Guru The original Amiga A1000 has 256KB RAM and some Amigas like an A500 have 512KB. That is an example of a nice bit of information to expand your knowledge and brighten your day. Also, other people can enjoy the information above. My comment has no hate in it and I do no harm. I am not appalled or afraid, boasting or envying or complaining... Just saying.

    nah, buy an Amiga haha the Amiga can handle 4 drives the same time from birth on ;-)
    What we would really need today is a floppy controller for mainboards coming without a controller onboard... as a PCIe card (or PCI card, most boards still have PCI)
