Where great old Macs live again!

Hello All,

I posted this on 68kmla and thought it might be useful here for anyone who is encountering issues with CF card storage and the SE/30.
I will detail the solution that worked for me below for anyone interested. (LINKS marked throughout and included at the end for reference)

TL;DR  Ensure that you have an active terminator installed on the external SCSI port before attempting to format a CF card with Lido 7. Ensure your jumper settings on the SCSI > CF adapter are set to ID=0 and on-board Active Termination=ON for internal use (on artmix's RaizinMonster this means all jumper pins removed).

SUCCESS!!! I can finally breathe easy after a couple months of fingernail-biting Mac-life-support-limbo...

On Saturday I received two packages I was expecting:

1) An DB-25 male (external SCSI) active terminator from SF cable (thank you to Paralel for bringing my attention to external termination; this unit was $8.77 including shipping; I also went with active termination over passive because of the old wiring in my building, just to be safe) (LINK 1)

2) The Mac ROM-inator II (LINK 2) that allows the SE/30 to boot into System 7 from a custom ROM chip (also handles 32-bit addressing, so you don't end up having to install MODE32 to max the RAM out at 128 MB; I currently have 32 MB installed but plan to max it out at some point)


For good measure, I re-formatted the CF card using a USB reader connected to my TiBook (Sabrent makes a decent one which you can pick up on Amazon for cheap (LINK 3), and Disk Utility on Mac OS X Tiger which allows you to read/write Mac OS Standard floppies (LINK 4) with a USB floppy drive (LINK 5) and partition storage devices using the Mac OS Standard partition scheme.


After installing the active terminator and seating the custom ROM SIMM into the tray on the logic board, I booted the SE/30, choosing the RAM disk option. To repeat, with artmix's RaizinMonster (SCSI > CF adapter) (LINK 6), I had removed all of the jumper pins, which sets the SCSI ID to 0 and ensures on-board active termination is ON for internal use.

After being greeted with a System 7 desktop (running off the ROM chip), I inserted the floppy that BadGoldEagle provided the image for, running Lido 7 off the floppy.

NO MORE ARBITRATION / TERMINATION ERROR!! After scanning the SCSI bus, Lido found my RaizinMonster SCSI > CF adapter just fine. I was able to format the card; I chose to split into three partitions:

1) 1 GB "Macintosh HD" - The primary partition I will use with System 7
2) 700 MB "System 6" - I will load System 6 onto this partition and switch between the two using System Picker when desired.
3) 2 GB "FreeSpace" - I will use this final partition for long-term storage of applications/files; to minimize risk of wearing out the boot partitions (CF cards have a limited number of write cycles)

The remainder was left as unformatted free space.

Lido formatted and partitioned just fine, finally mounting all three partitions as separate hard disks on the desktop!


I rebooted from my System 6.0.8 install floppy, and installed the system software with no problem onto the Macintosh HD partition.

Eventually I will run through the upgrade cycle (creating several install floppies) to get it all the way to System 7.5.5 which is where I will draw the line. There is a great little site called that walks you through installing Classic Mac system software and includes links to patches and enhancements to get your 68k Mac running at its best! (LINK 7)


As I detailed in a previous post, this has turned into the best-case scenario. I now have two boot partitions on the CF card, plenty of free space for storage, a custom ROM I can boot off of in emergencies with the added bonus of built-in 32-bit addressing, which as said before eliminates the need of installing the MODE32 utility for maximum RAM utilization.

The SE/30 now proudly sits on my bedroom desk, where my girlfriend and I can write stories, screenplays and the like distraction-free, with an ImageWriter II for that satisfying retro dot matrix print feel.

Next goals include getting Ethernet running on this machine! Thank you all for your assistance, this was a definite team effort and I couldn't have arrived at this solution without your input.

Thanks for this! I recently bought the SCSI2SD PowerBook edition. I forgot all about Lido,
It was a big help.
Michael, why did you choose the ARTMIX product over the SCSI2SD?

Hi James; there was a lot of buzz around Artmix's CF to SCSI conversion kits at the time that I took on this project.

I actually overspent a bit by getting the RaizinMonster (I could have gotten his AztecMonster and accomplished the same task for a bit less).

This is the first I'm hearing of the SCSI2SD. It's nice to know there are multiple solid state solutions out there.

My Essie is still running strong, albeit on 32 MB of RAM. My next investment will be maxing that out at 128.
