Once you cast a spell from the top of your library, causing The Reality Chip to no longer be attached to a creature will have no effect on that spell.

Although it causes an Equipment to become attached to a creature, reconfigure is not an “equip ability” for the purpose of cards like Fighter Class and Leonin Shikari.

Reconfigure represents two activated abilities. Reconfigure [cost] means “[Cost]: Attach this permanent to another target creature you control. Activate only as a sorcery,” and “[Cost]: Unattach this permanent. Activate only if this permanent is attached to a creature and only as a sorcery.”

An Equipment doesn't become tapped when the permanent it's attached to becomes tapped. For example, if you attack with a creature that is equipped with Acquisition Octopus, then use reconfigure to unattach Acquisition Octopus after combat, the Octopus will be untapped and could be used to block during your opponent's turn.

If a permanent with reconfigure is somehow still a creature after it becomes attached (perhaps due to an effect like that of March of the Machines), it immediately becomes unattached from the equipped creature.

If an Equipment with reconfigure somehow loses its abilities while it is attached, the effect causing it to not be a creature continues to apply until it becomes unattached.
18 Feb 2022
As soon as an Equipment creature with reconfigure stops being a creature, any Equipment and Auras with enchant creature abilities become unattached. Auras that can enchant an Equipment that isn't a creature remain attached to it.

An Equipment creature with reconfigure can be attached to creatures by effects other than its reconfigure ability, such as the activated ability of Brass Squire.
18 Feb 2022
Attaching an Equipment with reconfigure to a creature causes that Equipment to stop being a creature until it becomes unattached. It also loses any creature subtypes it had.
18 Feb 2022
The top card of your library is still in your library and not in your hand. You can't discard cards from the top of your library (for example, to activate their channel abilities).

Similarly, if an Equipment is tapped, its reconfigure abilities may still be activated and it may still become attached to creatures. Becoming attached doesn't untap it. In most cases, an attached Equipment being tapped won't affect gameplay, but it will be relevant if it becomes unattached again before it untaps.
18 Feb 2022
An Equipment creature can never become attached to itself. If an effect tries to do this, nothing happens.

You must pay all costs and follow all timing rules for cards played from the top of your library this way. For example, you may play a land this way only while the stack is empty during one of your own main phases, and only if you haven't played a land yet this turn.
