CoreDump is right.
The (non-SCSI) Hard Disk 20 does not work with the Macintosh SE/30. The Macintosh SE/30 has the same logic board and ROM as the Macintosh IIx, which does not support the Hard Disk 20. Therefore, the code to support the drive is not included in the ROM of the Macintosh SE/30...
Thanks. I'm mostly interested in the older SGI now. Working on a Personal Iris IP6 with just 12M of RAM from about 1990ish. Trying to rescue and image the drive that has an early version of Alias/3 software on it.
It works with SmartPort protocol - the actual physical interface doesn't matter at this point as they are all handwired!
If it's SmartPort signaling over the wire, JeffP's work should be ok and we have things booting on a variety of Apple2 hardware.
Here is my physical interface to the IIc:
I was never on Neko, it went belly up before I started collecting. But the Fuel PSU converters are back:
I got one and have been using a gamer PSU from Amazon (to get max 5v rail) for over a year...
Lots of people can help you real-time with getting that going over in the SiliconGraphicsUserGroup Discord: http://sgi.sh/ click on the microphone....
A number of users there have big o350 setups and have gone thru the pain of all the L1 and L2 configs to get it all to work as it should.
As for software- if you ever get a SGI that can run the last two versions of IRIX - 6.5.22 or 6.5.30 - most of the R5k systems or greater - you are in luck.
I'm part of a group that has been working for a few years now (since 2020) on RSE - RPM Software Environment for IRIX. It's a project that...
I don't want to knock indys that much - hey they run IRIX. If you have a personal attachment to them yes. Most I've seen were just rips for printing :)
Nice Fuel- so far you are the only person I've met w/ the 900mhz IP35 and V12 (same as mine). Mine does not have the DCD so you have me beat...
O2s are the Mac Mini's of SGI: just bring your own keyboard, mouse (uses PS/2) and Monitor (VGA). SGI did make an early LCD panel, so early it was before DVI standard so it uses a very special digital connector and you have to have a special sub-board in your O2 to use it. I have a panel and O2...
Some actually do. The O2s are well known for their incredibly brittle plastics. The older systems are made like tanks. There seems to be a link with quality of plastics and price of system. A 100k system has better plastics than a 20k system.
Surprisingly I've built this since only 2019. In fact, my very first ever VCF encounter was to come up to a Festivus and trade a Next slab for the Personal Iris- my very first SGI at that time. Since then I've been very lucky with people and being at the right place at the right time. The most...
I have a lot of computers, but the only things I really collect now are older SGI systems.
In my collection:
IP7 Powerseries 4D/320VGX (runs 4D/IRIX 3.3)
IP12 Personal Iris
IP20 Indigo 4k
IP25 Power Challenge
IP32 O2 10k
I love them all...
It's early, it will have to be a different board to be able to handle daisy chaining other drives... so there is time to enjoy your Atari FN and maybe by the end of the summer this will be all worked out.
Also @tschak909 sounds like he will do some ProDOS hacking to add networking...
