Default Re: Gemini 80-Bus System

Some progress to report...

I have now booted the system (sort of) from a Gotek, using a track interleaved disk image with output arriving at the serial port. I still have a few issues to investigate as I do not yet see the A: prompt. I will look into this next week. Both the 32k and 64k images behave the same. It looks for all the world like the serial parameters have been changed by CP/M loading.

Code:
57344 bytes -  RP/M for Gemini V2.1
Executing boot

Gemini Multiboard Auto Density System (1.4)

        64k CP/M vers 2.2
I also have discovered that the previously mentioned IVC failure is due to a dodgy output transistor. If that is all that is wrong, that is an easy fix. I will try and sort this this week and boot the machine using the IVC for display.

If I get all of this working I will publish the details on http://glasstty.com.
