![]() implementation of n-key rollover) not offered by USB. However, the PS/2 keyboard connector still retains some use, as it can offer some uses (e.g. Many legacy-free PCs include modern devices that may be used to replace ones omitted, such as a memory card reader replacing the floppy drive.Īs the first decade of the 21st century progressed, the legacy-free PC went mainstream, with legacy ports removed from commonly available computer systems in all form factors. Legacy-free PCs can be more difficult to upgrade than a traditional beige box PC, and are more typically expected to be replaced completely when they become obsolete. Netbooks and ultrabooks could also be considered a portable form of a legacy-free PC. Removing older, usually bulkier ports and devices allows a legacy-free PC to be much more compact than earlier systems and many fall into the nettop or all-in-one form factor. According to the 2001 edition of Microsoft's PC System Design Guide, a legacy-free PC must be able to boot from a USB device. A USB adapter may be used if an older device must be connected to a PC lacking these ports. According to Microsoft, "The basic goal for these requirements is that the operating system, devices, and end users cannot detect the presence of the following: ISA slots or devices legacy floppy disk controller (FDC) and PS/2, serial, parallel, and game ports." The legacy ports are usually replaced with Universal Serial Bus (USB) ports. This model is not to be uploaded or sold in any form and is intended for personal use only.A legacy-free PC is a type of personal computer that lacks a floppy and/or optical disc drive, legacy ports, and an Industry Standard Architecture (ISA) bus (or sometimes, any internal expansion bus at all). Well then, hope this little angled extender piece will give you more play options for your Legacy Metroplexes too! Happy 3d printing and love to see what you guys come up with (especially with more sets done up!) The clips should be printed sideway to give the 'fingers' the ability to bend slightly and not snap.Īlso, the end caps will need to be super glued into place to hold the clips tightly. Once the Junction pieces have been printed, snap on the corresponding ratchets into them and then it may take a bit of strength to force Be prepared to snap a couple along the way as again, this is quite challenging to put together. Once these are set in place, the peg will hold everything together.ĭue to the strength and stiffness required for the parts, it is recommended to print them with more walls/infill. The attached diagram shows the parts for this build and how they go together.įor the front and back junction, once their ratchets are insert, are to be somewhat forced fit into place. Now attached, the drill buckets can be further extended and angled downwards to the ground! And of course, lifting it right off the ground into a stowage mode is now possible too!Īnd never one to miss the chance with presented, this piece also comes with a bunch of 5mm ports for more blasty goodness to be added on! In any case, then put together, it should look something like in the attached photos, with the inner ratchet pieces able to hold the arms at specific angles.Īnd now, to connect the extender to other parts of Metroplex, just do the clippity thing similar to how the other pieces connect up. ** A word of warning though - this is a fairly challenging piece to print and assemble and once the two halves are connected, will be hard to separate. Here's the third piece of upgrade for Legacy Metroplex - an articulated extender piece for Sparkdrinker to allow his drill buckets to reach the floor or be angled upwards in his alt mode!
