@omgmonsters I thought it was cursed there for a minute like yours lol considering the condition it was in when I picked it up :)

UPDATE: it lives :) Looks like the startup extension doesnt like running on OS 8 but is perfectly happy running on OS 8.1. The CPU is running at 27 MHz though which is concerning. I wonder if the 20MHz oscillator somehow is not working.

@omgmonsters thanks. There wasn’t anything else you had to do to get the 040 working?

I loaded macsbug onto my mac to see what was going on while its loading the "startup carrera" extension, here's what i'm seeing... Illegal instruction at 0028847E 'FOND 3FFF 017A Chicago' Anyone know what this means?

@omgmonsters, care to help us out? :)

Ok so after a lot of messing around and copying of files I finally was able to get OS 8 installed. Found a lot of problems with the scsi2sd in which it very much does not like having a second device configured and caused issues (yes, the active terminator setting is checked). Now that I have...

Yes, I am. When I did the 7.1 installation I selected universal install for all macintosh platforms. When I ran the 7.6.1 installer, I did what it mentioned in the document. Start WishIWere and set it to Macintosh IISI and rebooted, that allowed the 7.6.1 installer to go through without...

Hi @BacioiuC, yes i've been following the instructions on that page however there seems to be some issues i'm running into using the instructions. I tried to install 7.6.1 but i'm running into some issues when the installation finishes where it's telling me immediately that it cant run on my...

Hey everyone, I'm working on installing mac os onto my SE/30 using a floppy emu and a HD emulated via a SCSI2SD. ROM is a custom rom but is taken from the rom supplied by bigmessowires.com. Here's what's happening... Installation of 7.1 works as expected using the floppies, i'm able to boot...

@Franklinstein, that was sort of my motivation for starting this thread in the first place, not only to see if there was a way to reproduce a CPU but also to pick up on a project started by big mess o wires in which had a project started to build a classic 68k mac on an FPGA. The project is...

Xilinx software comes with a program to convert C code into VHDL/Verilog. I had read about this before where programmers can use HLS to convert programs into FPGAs for greater performance instead of having the CPU constantly running. As I mentioned before there is a C implementation of a 68040...

Hi @Byrd, not so much projects involving raspberry pi emulating a 68000 CPU but actual vhdl or verilog code creating a 68040 cpu. I've come across a few projects, one called fx68k but that looks like only a 68000 cpu. There is a project that has a 68040 written in C, maybe that's a good place...

Hello macintosh friends. I have been searching all over for a way to replace a 68040 CPU with a more modern alternative, something along the lines of a FPGA to be used on an accelerator card or even as a whole logic board replacement. There are a few projects out there but most of them stop at...
