SE/30 project

[petteri]

While waiting to get new System disk I'm switching to the square dotted motherboard. I found this thread 



 and I downloaded bunch of SE/30 schematics. Should I go though with flux and resolder UE8 and its neighbours? Or would it be better measure first  UD8 and UK6,  UE10 and UI8  etc...? 

 

[petteri]

Alright, it turned out that I have A0 line broken between UD8 (pin4) and UK6 (pin 10). Tomorrow time for some jump wire.

Managed to fix the SE/30 logic board with the square dots errors. My jumper wire would not pass critical inspection but the computer starts up now with a startup chime and no more screen issues.

Today I was driving around and buying Macintosh parts. I bought one more Apple Extended Keyboard II, SD2SCSI v4.2c and Asante Desktop EN/SC 10T SCSI to Ethernet adapter (with original box, install disk and manual). The last item was pure luck, I asked the keyboard seller if he had some other old Macintosh parts or equipment... :-D

The next step is to set up the SD card with some software and try to boot my SE/30 with it.

SCSI2SD took a moment to set up but nothing too difficult. I did a setup of two 2GB drives and SE/30 booted up nicely on both 6.0.8 and 7.5.5. The floppy drive was able to format disks so I decided to create a boot disk for 512ke project:





I don't have any real DD disks so I just taped over the hole on a HD floppy. It seems the floppy disk drive is pretty picky with the thickness of the floppy and it took couple attempts to find the correct tape. After successful 800kb format I copied really minimal System folder to the floppy and tried it on 512ke. 



The next step is to 3d print a bracket for the SCSI2SD and install it nicely inside the SE/30. It has at the moment 8MB RAM in a 8x1MB arrangement which should be fine for now. I haven't tried Asante EN/SC yet, I have to think a bit how it will connect to the rest of the home network.

Nice work! I have a bodge-y jumper hidden inside one of my SE/30s somewhere too.  

Is that a specifically Finnish keyboard on the left?  Interesting layout, I haven’t seen one with such a narrow Return key before.  But I’ve probably only ever seen the US keyboards in person.

It is some kind of "very cold and northern European countries" model, M0110 SV. Compared to the modern Finnish/Swedish AEK II it has some unusual keys like Ü an É.

Yesterday I printed out a mount for the SCSI2SD. This is not my own design, I used the one from this thread: 







It printed out ok without the LED periscope thingy. The only modification I made was to add two spacers as I have the SCSI2SD upside down. The position is pretty ok and it is easy to reach the SD card if necessary. So much space left there. Maybe I should get some accelerator or video card :-D



The next task was then to get online. I plugged in the Asante EN/SC and it looks healthy.



 But there was some strange issues with drivers. Crashes etc. I had to boot from the floppy in order to clean up the mess. I turned out the disk that came with the Asante EN/SC wasn't exactly the right one...



Luckily the 6.0.8 pre-built image contained installer for Asante, I just had to "burn" the image on a floppy and install it from there. I set up a 2015 MBP with an USB eth adapter act as a bridge and I entered MacTCP settings manually. And there it was, I was able to use Fetch to connect Macintosh Garden.

Looks like there is no SSH client for 6.0.8 so I wonder whether I should have a dedicated RaspberryPi or similar to act as a terminal/FTP/AppleShare server and then do modern SSH from there onwards.

I've got the drivers for Asante SCSI to Ethernet converters on my server in the uploads folder (see signature) that work with System 7.5.5 if you're interested.  The SE/30 works much better on a network with 7.5.5 than 6.0.8.

on my server in the uploads folder (see signature)

@Byte Knight what are you running that AFP server on, out of curiosity.  Are you taking any public. facing precautions? 

 

[pcamen]

Ah, I see it is called raspberrypi / ApplePi, so I'm guessing A2SERVER.

You got it.  And you forgot to leave a message in the "I was here!" folder!  I've got to leave guest access on or it won't work with the IIgs'.  But I've got it all backed up on a HD.

 

[pcamen]

And you forgot to leave a message in the "I was here!" folder!

Hmm.  I did add a .txt file there.  I wonder if it didn't copy properly.

Interesting - I missed it because it put your text file at the bottom of the window which is sorted by date, and the dates are all messed up on the server... Anywho, did you get the drivers to work?

I installed a full 7.5.5 and added EN/SC stuff on it. Also, important bit was AppleShare Client 3.7.4 in order to access my share on RaspberryPi living in a different subnet. I have a RetroPie v4.5.1 (Linux 4.14.98-v7+ armv7l GNU/Linux) so the instructions how to install the recommended netatalk 2.1.6 did not work. But luckily with apt get netatalk I was able to install  2.2.5-2+deb9u1 version which seems to work just fine. 

I hope I don't have to use Basilisk and copy .dsk to SD card anymore. 

My next challenge is to setup telnet/ssh and try out web rendering proxy https://github.com/tenox7/wrp.

 

[petteri]

With Netscape 2.0.2 and WRP I was able to get WWW working. I have WRP running on a RaspberryPI 4 along with PiHole, WG and other network stuff and it works just fine. Of course web sites are pretty difficult to read on a B&W display.

I was planning to sell the other SE/30 logic board. But it seems I didn't manage to fix it really. It booted up but no chime. However, next boot failed. I thought the disk went bad so I tried with another disk. Same result, 1st boot ok but after that it fails. 

Turns out the logic board has some issue causing all the writes being nonsense and corrupting the disk. Also, there is no chime and SCSI doesn't work. Most likely it has some broken traces I guess?

I decided to auction that board as is with 1 euro starting price. Let's see if I get more that 2e from it :-D

Is the SE/30 board on eBay, or somewhere else? I'm always interested in SE/30 parts boards in Europe

It is on https://www.huuto.net/kohteet/apple-macintosh-se_30-emolevy-rikki/522353125 at the moment. No offers so far, so it is ok to pull it out if you want to purchase it. Shipping to NL using Finnish post would be 22e. :-(

Ouch, the shipping does put a damper on it. Tell you what, just let the auction run its course, if it doesn't sell there I can look at what I'd offer for it, if that's alright.
