Hello,Nice to meet you. Are you referring to the discussions on the 68kMLA forum about installing the Total Systems Gemini Ultra accelerator into a Mac 512k? I’ve been following the community threads with great interest—it's a fascinating topic! I noticed your name came up when I searched here, so I couldn’t help but reach out. I’ve also tried installing it on a Mac Plus before.Best regards,

Hi# nice to meet you too. Yes, the Gemini board is quite impressive. I am not 100% sure in which Mac input it. I thought it went onto a Plus.

Thank you for your response. Installing GeminiULTRA on a Macintosh SE is easy. However, it's not the same with a Macintosh Plus. I removed the MPU from the Mac Plus board, combined a small 68000 with a conversion board and header pins to create a clip, and successfully connected it. I did that with Gemini II. I am very interested in putting Gemini on a Macintosh Plus. By the way, is the operating speed of your Gemini ULTRA 50MHz?

Right off the bat, my adapter is malfunctioning.
When I switch my Carrera 040 to F mode,
the screen remains gray except for the Finder menu.
It still worked in M mode, but now it no longer works in M mode either. The SE30 works fine in S mode.
I've reinstalled System 7.1 several times, but the problem persists. Has anyone else had the same issue?
I'm wondering whether sending it to Germany and having it checked for symptoms is the best way to do this.
I'd appreciate your feedback if you read this.
I suspected a problem with my Carrera 040 and replaced it with my old DayStar adapter.
The S, M, and F modes switched properly, and the benchmark software ran, so I knew the Carrera 040 was still working. Of course, the screen is terrible, with a grid pattern.
