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. ;-)

Yes, there is a runtime for 68k, which runs on 7.1, but I've discovered version 2 is buggy and RealBasic is not optimized for older 68k Macs. I've decided to stick with Director, Hypercard, or Filemaker for developing low-code solutions for 68K Macs, with tool choice depending on the need for...

Thanks! Hopefully my SE/30's 50-SE30F Accelerator will help the slow battlestation.

I have some experience with Filemaker, Hypercard, and Director but wanted to try REALBasic to develop apps for late 80's 68k Macs. Does anyone know what version of RealBasic would work best on System 7.1 on an SE/30? @Action Retro I saw you use REALbasic on your Battlestation - any ideas?

Thanks for the update. Very cool! I assume this the best relevant post on 68kMLA? https://68kmla.org/bb/index.php?threads/se-30-design-for-drop-in-replacement-power-supply.47462/#post-534143

Just a quick note with results on the new Interware Clone "Booster 30-SE50F" 50Mhz 030 w 68882 FPU accelerator in my SE/30 purchased from zigzagjoe on 68kMLA. Installed in the PDS without issues, requires no software, and performed a bit over twice as fast than stock (based on Speedometer 3)...

Good answers above. Since I had both an internal and external BlueSCSI V2 here's what I did to move my SE/30 SCSI2SD volume to BlueV2. Requirements BlueSCSI V2 Internal BlueSCSI V2 External (Optional) PC or Mac with Basilisk II (Basilisk is optional, but makes the process much faster)...

Thanks JDW. Seems like the best direction for these accelerator projects is more open-sourced like BlueSCSI. Then multiple sources could build, improve, and promote. There are so many super-smart people (Zane included) in the community that could contribute and benefit.
