A nice SE/30, /w Options :-)

[uniserver]

Mcdermd hooked me up. - memberlist.php?mode=viewprofile&u=6241

This SE/30 has stuff in if from other members too!

max1zzz - memberlist.php?mode=viewprofile&u=21831

he made some super kick butt terminated SCA to 50 pin scsi adaptors for me!





Not only does this thing look nice but the inside has a bunch of cool features.

- Ceramic Cpu

- 32 megs of ram - i was able to find ( 8) 4meg simms!!

- AUI/TB-2 Mac Con NIC

- First class cap job by mcdermd!

- Dougg3s Hacked ROM, Enabling all kinds of really great features! including booting Systems7 + Apps, all from ROM!!. memberlist.php?mode=viewprofile&u=14318

- And to top it off with a fresh Pram battery.

It has a brand new Analog board, its literally sparkling shiny.

Freshly Cleaned/ Greased Superdrive Sony 2mb

73gb 10,000 RPM SCA Hard Drive

like brand new CRT

What more could you ask for from a SE/30?

A little update.

the mac con card that was in my IIsi died… it may of happened at one point from me installing the ribbon cable backwards.

Either way it doesn't get an ip no matter what i do… even if i set a manual ip it just says host is down in the pings.

the FPU part of the card still works… and the Pass through part should also still work maybe… just the network part is DEAD..



So i swapped the 10bt faceplate from the not working IIsi NIC

with the working NIC in the SE/30. All is working fine with the SE/30.





Also here is a picture of the inside of the se/30.



So if anyone has an extra one of those cards let me know.. I could even send you this one, still would make a nice FPU add on and riser.

id like to get the IIsi going as well… i want to do the Radius ? pivot video card thing… would love to get some better resolution over 640x480! + NIC.

I stupidly reversed the cable direction on a MacCon SE/30 once. It fried it the same as yours.

 

[bigmessowires]

Sorry about the dead Mac Con card. If you're left with a spare faceplate for the back panel, I'd be interested in it. I need some way to mount my custom Radius Color Pivot cable in my IIsi, and the video connector fits perfectly into the thicknet opening in the Mac Con's faceplate.

Hey there, I do have a working BNC / AUI faceplate that i am not using right now.

I am going to try and find a replacement NIC for my IIsi.

I'll let you know soon, if i cant get together anything its definitely up for grabs.

Were there more NIC options available for the IIsi over the SE/30?

Or was pretty much any NIC that would work for the IIsi would work in the SE/30 as well?

 

[Blinkenlightz]

The PDS NICs are interchangeable between SE/30 and IIsi it seems -- but the IIsi has the possibility of the NuBus adapter for its PDS, which opens the door to lots of (much cheaper) NuBus NICs on that side. The SE/30 necessarily has to use a PDS NIC or a SCSI Ethernet adapter.

 

[uniserver]

awesome , anyone wanna sell me a Nubus adaptor for the IIsi?… Trag sold me a couple super COOL 10/100 Nubus ethernet cards!

 

[techknight]

replace the thb16j04?

 

[uniserver]

is that like a borns filter type thing?

is that something you came up with … or is this a known thing to blow once you hook up the cable backwards ?

 

[uniserver]

could it be something that is just needed for the BNC, and maybe no needed for the AUI,

looks like there is a THB16J04, on the BNC/AUI ADAPTOR plate, maybe i could steal that one, because i am not using BNC anyways.

 

[techknight]

No no, thats the isolation transformer that physically isolates the network interface from the chip.

I think there was another thread on this chip failure and replacing getting a NIC back online. If you plug the cable in backwards, it likely kills those isolators. If it killed the main IC, then the ethernet driver would never see the card.

It appears both the AUI card has the same isolator as the main ethernet card.

This chip is used for ALL interfacing, it physically isolates the network interfaces from the main controller IC. Why they do this? I dunno. maybe impedance reasons, maybe lightning reasons, I dunno. But if it openes up, then you cant see any networks.

Here I linked a datasheet you can use to measure in ohms the devices. if one of the transformers is open then youll know it.

Also when you plug a cable in backwards, Does it kill the plate? or does it kill the card? or does it kill both? If its one or the other, You know where to look.

 

[uniserver]

the plate works with the other working card… so looks like it pops the card.

gotcha well let me fire up the heat gun swap the chips around and see what happens.. thanks for shedding some light on this subject!

 

[uniserver]

I did swap that out,

And it does now work too!

but i'm thinking the problem was my 29mhz OverClock was too aggressive.

after i changed the delta THB16J04, it still would not grab an IP.

So i figured i would change IIsi's for giggles and this one is bone stock speed 20mhz

and sure enough it works fine.

Classic mac looks odd on an LCD. lol.

For future reference, look at the datasheet and use its pinouts to test the windings for opens before you pop and replace

 

[uniserver]

i like to shot gun… keeps life interesting.

You've never run Sheepshaver or Basilisk on a modern PC/laptop ?

 

[bear]

The reason to do it is that the Ethernet specification explicitly calls for 60 seconds of isolation protection to 1500Vrms @ 50-60Hz.

 

[NJRoadfan]

Now all the SE/30 needs is a Micron Xceed video card with the grayscale adapter.

 

[uniserver]

i'd love one, but chances are pretty slim i will ever get my hands on one
