|So how do you upgrade an Amiga 600?
As I already explained, the Amiga 600 is hard to upgrade. Above all upgrading its processor is a problem because the Amiga 600 doesn't have a processor socket and the 68000 is a SMD chip soldered on the motherboard. None of the expansion connectors of the Amiga 600 provides the necessary lines to upgrade the processor (like those of the A500 or A1200 did). But still some companies managed to upgrade the A600 by pressing a chip socket upside down on the 68000 on the A600's motherboard, stealing the necessary lines.... yes, you've read correctly, read again if you don't believe it.
Some, or to be more precise, two accelerator card designs were made on this basis, equipped with 68020 und 68030 processors. The Apollo 630 squeezed the most out of the Amiga 600, boosting this little computer up to 50 MHz (which was a LOT at the time!), allowing for 32 MByte EDO RAM (which was even MORE at the time) and boasting a full MMU and FPU on the card. With this thing, the Amiga 600 would not only outspeed its big brother the Amiga 3000, it would also run Linux and MacOS and speed up Amiga games to never known speeds -- if you ever got it working :-)
This shows a SysInfo speed comparison between the upgraded Amiga 600 and other Amigas:
