(I believe there also were similar 286 upgrades from the MakeIt 486 series..)
My pleasure, Jo22, thank you for replying!!!
Wow, from 286 to 486!!! That would have sent me nuts as a kid when I had the 286.
You're welcome. ^^
I also had a 286, a 286-12 with CD-ROM and a PAS16.
It could even play some QuickTime/AVI videos and large *.wav songs on Win3.1.
Speaking of the 286 and the Cyrix 486es (SLC, DLC, SXL)..
The Commodore Amiga platform had so-called "Bridgeboards", the Atari ST and Acorn PCs, too.
You may find that interesting, too. Back in the day, they were what VMs are today.
Applications could be run in a window, side-by-side with the host operating system.
In the mid-80s, the Amiga originally had a socalled sidecar (see model A1060) which was an 8088 PC in a box.
Later on, Atari STs also had similar emulator boards that could be soldered inside of the computer (like PCSpeed/ATSpeed).
This was much faster than PC emulators of the day (believe it or not, they already existed in the 80s, just have a look for PC-Ditto)
Anyway, back to the Amiga. These bridgeboards often had 286 chips or 486 chips on them,
which made these platforms PC compatible. So installing these 486 upgrade chips on them wasn't too uncommon.
Some bridgeboards designs were even based on the 286 bridgeboard models, but included a 486 CPU core instead.
Hot-rod versions also came with high-clocked 486 chips, probably SLC/SXL types form Cyrix.
By the way, here's a quick explanation of the different types
of these Cyrix/Texas Instrument processors.:
486SLC has 386SX pin out (Single Word - 16-Bit, Low Cache)
486DLC has normal 386 pinout (Double Word - 32Bit, Low Cache)
486SXL has normal 386 pinout with bigger cache
