Yes @nekogahora280 I purchased your Gemini II. I will be honored to take good care of it, and I will post my benchmarks and photos :) In the meantime, I hope the Gemini 020/030 comes back to life somehow. I may try this board in my spare SE.

A sad update. I tried to update the 32Mhz crystal with first a 50mhz one and then a 40Mhz one with no luck. The SE would not boot. I went back to the 32Mhz crystal and all was good. (I should have stopped there). Then I got an idea to try to remove the on board RAM and try the faster...

Very cool! Fascinating to see the evolution of the board. That was about the time I purchased my SE for college. I recall when I went shopping for accelerators that the Geminis went for a premium. I guess now I know why.

Hey Jeff, after I got the board I poured over your post on 68KMLA! Amazing design. The amount of engineering effort and investment was significant. It was that rare time when upgrading the SE, Plus and 512 was a the main focus of the burgeoning accelerator industry. I’d love to know the...

FYI - I created a related post - Accelerating an Accelerator - Total Systems Gemini 020 to 030 for Macintosh SE

I was blessed to find a Total Systems Gemini 020 for Macintosh SE (Also called the Quesse PDS accelerator for SE). These accelerators, which came out around 1988, were designed to be upgradable to the 030 and had excellent performance, besting the SE/30 and IIx in real world tests. See MacUser...

Hi all, Does anyone have any recommendations for the best way to search and buy vintage computing equipment from Japan?

Thanks @Kai Robinson !

I'm planning on upgrading my Total Systems Gemini 020 SE accelerator to an 030. Is there a reasonably reliable seller of 030s and 68882s? I'm wary of stories of spray painted fake chip masks . . .

I wish the WarpSE project will continue @Zane Kaminski. I noticed this vid back in September shows the performance promise of the beta version - much faster in CPU and Graphics than the already excellent MacEffects Performer for the SE. Any updates? The SE market has room for more than one...

That is excellent performance @Zane Kaminski. Looking at the MacWorld July 1991 article, that is taking the 68000 to impressive heights where only 030 and cached-up 020 boards went in the day.

Great news and count me in!

With the 2024 show being so great (nice seeing @Action Retro ), here's a shameless plug for the Vintage Computer Festival SoCal in Orange County, California February 15th & 16th, 2025. It's a great show, and you can pair it up with a trip to nearby Disneyland! https://www.vcfsocal.com/

Hey JDW - If you get one these would love to see an analysis using your EE knowledge. ;-)
