I have so far built a facility to trace the execution, dump the assembly and all the memory ops to go with it.. I will put it up on Github at some point.

I am just hacking my way through it, hell I am retired.. what else do I have to do all day. :)

Thank you for the attached files.

Ok great, thanks for the heads up. I was looking at the MAME stuff and thought I would just integrate what I needed as I figured it out. I am looking for this... MDU User Manual, Michael Dhuey, June 1988.. its not in the blue book. I use the same 68k emulator as MAME does, Musashi its all in C...

I am tinkering with a Mac IIci emulator of my own for ROM modifications, does anyone know the mappings of the MDU and RBV registers? At boot I see reads of the boot vector followed by a curious write to rom, which looks like its tweaking some control registers. Since the next thing it does is...

Agreed.. a nightmare to read if you are used to using schematic design tools.

How correct is this schematic from BOMARC? I found out on the web...

I think I have a method.. I use Fetch to log into Macintosh Garden, then on my linux box (through ssh via my iMac LOL) I find the exact name of the file and do a "get file" from Fetch.. it seems to work fine.. but its a real hack.

I was able to get my networking up and running, its slow.. but Fetch is crashing on downloading a list of files from repo1.macintoshgarden.org The Mac Iici has 64 MB of memory and I increased the size of the application memory, but it still crashes at some point. Is there another site I can...

Thanks, just a couple of days ago I was able to make it work.. with a ZuluSCSI, the RaSCSI worked fine on my Centris 650. I tested the same boot images with both the RaSCSI and the ZuluSCSI, so it may be termination.

Actually, it does affect RAM. In fact, it affects all components, especially when a computer is turned on and turned off all the time. The components and the board they are installed into warm up and cool down which causes expansion and contraction which is movement. That’s why you have to...

The Slaton modules I installed the other day were tinned, so they probably figured this out. Ages ago I designed a couple motherboards.. (80486 era, so it's been awhile), you pick this stuff up when you sell a few hundred thousand units.

You are correct, thanks for bringing that up. Dissimilar metals have different galvanic voltages, the greater the distance in galvanic voltages causes corrosion at a higher rate.

Yes the Slaton modules work great, other than the long memory test... and it took only 2 days to show up on my doorstep!

So my Mac IIci drive stopped booting, I was planning on updating to a RaSCSI so I guess it was time. After getting it all installed and using the web interface to build some volumes I can't get the Mac to recognize the RaSCSI drives.. I booted to floppy using the disk tools and it doesn't...

33 MHz PCI signaling is fairly forgiving, I worked on the original Intel EISA and ISA chipsets at Dell way back when. I also designed a PCI bridge for a graphics card using an Altera FPGA with fewer pins than a cheap Spartan 6 you can buy today. I had to hack the PCI config cycles in due to...

Years ago I had purchased physical copies of Code Warrior for my Mac Iici and Mac 7200, but I no longer have these CD's. Can someone help me get up and running with registration information? I am pretty sure I had Think C / Pascal before Code Warrior but I seem to remember CW more. Thanks

I was looking through the 68030 user manual and it talks about asynchronous cycles but I don't see any improvement over synchronous cycles, does anyone know what are the fastest achievable cycles for read burst / read / writes on a 68030? It looks to me that it takes at least 11 cycles for a...

As a separate execution unit on a small ASIC on the motherboard. Its been a long time since I had a G4 silver, but I know its there.. I think it was called "Orca" with all the information floating around the web I was hoping to find something on this to hack with. If you have a G4 silver check...

Your are correct Altivec is used in the G4, but Apple built a dedicated ASIC for media processing which was compatible with Altivec instructions. I was just curious if there was any information out there on this ASIC.
