Honestly, I'd probably just pay the premium and buy a kit if I did it today.
I did this during COVID lockdown when my hobby/project time was valued differently.
Yes, the base unit themselves might be cheap. But once you're looking at enthusiast-produced LCD replacements or optionally-purchased-in-the-90s expansion cards, having sticker shock is expected.
LCD parts are cheap if you want to put the domain engineering work and solve engineering challenges yourself. They are expensive if you're one-stop buying a targeted kit and just trying to max out your upgrades.
An HN poster might be willing to put in significantly more time head-desking and soldering to save $200. A producer buying a vintage Akai is not necessarily looking for an EE project.
To that producer, the functionally upgraded unit is "worth" a lot more than $300 since they're selling the products of it.
But that doesn't mean anything about the cost to repair, upgrade, or in the case of LCD replacement, modernize. The memory, flash, effects, and expansion cards are highly sought after, and you're competing with bigger budget established producers.
As noted, the expensive MPC60/3k replacements are just generic T6963C / RA6963 displays with the circuit bypassed (since sampler has the LC7981) and the correct pitch ribbon cable soldered.
Jazzcat + Ebay sell expensive replacements, but they are actually just cheap LCD displays with the driver circuit bypassed (since the MPC/sampler has a discreet IC) and an epoxy blob to prevent copycat work.
I need to dig up the wiring diagram, but the gist was from an EEVBlog forum post and only took an evening to reverse engineer.
Why not deploy as next.github.com subdomain?

There was also an effort some time ago to get opensource Darwin compiled and booted on ARM development boards:
Moreover, most modern CPU architectures will just fake the architectural register moves and just use register renaming techniques to avoid the issue completely.
TL;DR: any trick like this will just make your code slower and just use more architectural registers since neither the compiler nor the hardware will be able to reason about your intentions
I use this in my .emacs so Emacs can grab passwords from Keychain, but the same approach would work in bash too: (defun find-keychain-password (host) () (condition-case nil (let ((passstr (second (split-string (first (process-lines "/usr/bin/security" "find-internet-password" "-gs" host)) ": ")))) (substring passstr 1 (1- (length passstr)))) (error nil)))
