That would be the ‘Alternate Ethernet’ option that they said they selected. Good point about that setting possibly not being held after shutdown, in case they don’t have a PRAM battery or an ATtiny85 based RTC. To the OP, it would be worth considering picking up an SE/30 PDS Ethernet card that...

The ‘Alternate Ethernet’ wording doesnt have anything to do with being on a separate network. IIRC, it’s something to do with the type of driver. So your issue is elsewhere.

Reading @bigmessowires’ explanation, the TLDR is that the IIsi/ci only switch on their separate sync signals when a portrait display is connected, at the rather useless (for a multisync display) 640x870 resolution. Otherwise, it puts out CSYNC and SoG. So @rmoat your Dell LCD would work even if...

Griffin Mac PnP. I pulled up Bomarc’s IIsi schematics and looked at the pinout for the monitor output. It has composite sync as well as V sync and H sync on separate lines. Now I’m even more confused - I thought the reason these machines wouldn’t sync to my 15AV was due to lack of separate sync...

I know right? Ah, that’s helpful, thank you. So there are three sync methods in play across vintage hardware. I wonder if the IIsi and and IIci put out composite sync in addition to SoG.

I get confused between the sync methods that the different machines offered. I know the IIsi/IIci vampire video and Toby card are unique in that they don’t offer separate sync, and only sync on green. Then, later Macs came with more capable onboard video that supported separate sync. Let’s...

With the popularity of the LCD mod for the SE/30, there should be a surplus of old compact CRTs floating around the community - worth posting a WTB request.

Just general 100 series weirdness. You might find the issue comes back later on… or not ¯\_(ツ)_/¯

As well as a monitor that supports sync-on-green, as mentioned earlier, which is the trickier part. I have an Apple Multiscan 15AV that happily supports 640x480@66.7Hz, but refuses to work with the IIsi or IIci due to the sync issue. You have been lucky with your Dell LCD, but it’s likely to be...

Thanks for the guide! That’s a lot of caps for a small board

I came across a cap labelled as such in the PowerBook 1400/3400 series 45W AC adapter, and having looked up the meaning of WV I understood it effectively means the same as V.

Waiting for the big system crash due to the impossible configuration of total RAM installed🍿

Looks good to me.

Sounds about right to me (except that 81,920 KB is 80 MB). The concept is a bit like the knock-off flash disks that report their size as 1TB (or whatever) but only have e.g. 8GB of real storage and any accesses past 8GB loop back on themselves leading to data loss.
