All issues resolved. The 40MHz 68030 accelerator is installed and working in the A2000.

Here's a victory video of Black Lotus' 2019 OCS/ECS Amiga scenedemo 'Eon'. I am unsure if anyone will get the irony of this video, but the spark of that irony is what motivated this CPU upgrade from the Commodore 68020 board I was running before.

8MB 16-bit FAST RAM installed! Now to drop in the 68030 board...

Happily, was able to find eight 30-pin 70ns FPM 1MB SIMMs, so I can populate the 16-bit Zorro II RAM+SCSI card to 8MB in this Amiga 2000 upgrade.

Cracked open the Amiga 2000 and am moving from a 14MHz 68020 to a 40MHz 68030, and increasing FAST RAM in both 16-bit Zorro II space and 32-bit extended space.

The "new" accelerator is a GVP G-Force 030 (Impact A2000-030 Combo Series II) with 8MB 32-bit FAST RAM and 68882 FPU.

This board has a jumper allowing it to be fully disabled, which I will bring out to a toggle switch (for cycle-exact 68000 scenedemos).

Amiga people: Do any of the new accelerators that work with the Amiga 2000 allow fallback to the original 68000 by way of a PHYSICAL SWITCH or jumper?

I want an accelerator that can be disabled (without using soft-menus to control the state) so that the Amiga is able to fall back to its 100% exact original 68000 state, which some demos require to run properly, due to cycle-precise coding.

I have an A2620 68020 accelerator in my NTSC A2000, but it does not have a physical switch (just a soft menu) and the state gets lost when I juggle that soft menu and the need to also use Degrader to reboot into PAL mode.

Apparently the A2620 can be modified to add a switch, but it's beyond my abilities.

Many thanks.

Having an awesome time putting my new Parceiro II+ that just arrived in the mail through its paces on my Amiga 1000. I had the original Parceiro and it was a game changer, but the Parceiro II+ is just a polished vehicle for perfectly experiencing the Amiga as it was in its heyday.

Kickstart in ROM (no floppy needed!), HD / volumes on removable SD card, 8MB FAST RAM expansion, real-time battery-backed clock.

And I've been focused on the Kickstart 1.3 partition so far; I've hardly had a chance to play with the KS 2.04/WB 2.1 and AmigaOS 3.1 modes / partitions.

Such amazing work, David Dunklee! What a way to make the Amiga shine.
