Got everything hooked up correctly, and still no Terminal access, got the CR+LF and Echo working properly, could see the commands given, but am not getting any response from the SE/30 board. This would mean the CPU, the Serial controller, or the Glue chip is not working correctly. Going to...

This particular cable said RS-232, but no mention of Null output. The adapter will be here tomorrow finally.

It took forever to get that din-8 to DB9 cable from ebay. When I connect it between a PC/USB COM port and the SE/30 serial port next to the audio output jack, I get no flashing cursor or keyboard input in Putty or TeraTerm, both set to 9600, 8, 2 stop bits, no parity, no flow control. Have a...

I've got to try to fix this stock board, if all else fails the Reloaded board is a great option. Gives me some hope this can be a useful tool. Thanks.

Nice work! What are you using on the DB9 end to talk to the SE/30 board with? Have you been able to retrieve any useful info from it?

You're welcome! And thanks to Adrian for putting the spreadsheet together. Found an 8-pin to DB9 that claims to be RS-232. Already have a USB to DB9/COM port that will connect to this. https://www.ebay.com/itm/184211248546 The cable was shipped this morning, should have it by this weekend.

Great to hear that cable works, I'll get the 8-pin DIN to DB9. Thanks! Here's the spreadsheet Adrian prepared with the commands for terminal access to the pre-ROM boot: https://docs.google.com/spreadsheets/d/1zsc7ET5fyiOYWj1_AzOgafbrCVFED-7jzLH6ruCiAVE/edit?gid=1499087781#gid=1499087781 He...

I have plenty of good DB9 capable PC's here. Just can't determine if that 8-pin Apple printer cable would line up with the correct DB9 output, or RS-232 COM port input. A null modem adapter might be necessary to cross the Tx and Rx between terminals, in order to get that to work.

I have a good SE instead of a IIci, would an SE and Zterm work, with the same cable you used?

Rather than try to visually inspect this board for broken traces, it's time for a diagnostics program. In this episode of Adrian's Digital Basement: he uses a modem cable (8-pin to 25-pin), converted with Laplink cables, to connect to a PC's DB9 port with Terra Term - in order to obtain error...

At least I didn't make it any worse. Need to check the Reset and Clock lines today. Is there a way to check the ROM without a spare or replacement?

Made it through the Data Pin Matrix, all pins and continuity check out. Need to put this back together, and start looking for reset and clock signals. Do have an ATX extension cable. https://www.amazon.com/dp/B07L88HJ9X

The Pin Matrix Data chart insists pin N is the last pin of UK8, the CPU. The Pin Matrix chart lines up correctly if you ignore there are only (13) pins, and pretend the last one is N.

Has anyone here successfully completed the SE/30 Data Pin Matrix? I'm showing that the columns in the chart don't match the CPU Pin numbers, but everything else lines up. Example: I'm in CPU pin K13, but it tones at ROM Pin 16, at D8, Pin 10 at S1A and S3A, and Pin 1 of the FPU. The colors...

Got the CPU traces covered, and the ebay socket fully installed. Checked every last Address line on the Pin Matrix, all of the pins are there and connected. Will do the Data lines tomorrow.

Got most of the socket installed. There are some areas that look to have exposed traces, so I'll fix those with UV solder mask, and then finish the remaining pins. Pretty sure if I don't fix those exposed areas, a short would occurred.

Got the new CPU socket's. Dropped right in, and looks good so far. Will solder this in, and begin the Pin Matrix testing.

That flyback transformer looks in bad shape, that's likely where the burn marks are on the back of the board too. If that flyback is not working, that board isn't of much worth, unfortunately. You could try hooking the SE logic board, to your SE/30 analog board/PSU, to see if the SE logic board...

That horizontal line on the screen is where I would start. You can download the repair book, The Dead Mac Scrolls: https://archive.org/details/mac_The_Dead_Mac_Scrolls_1992 On page 49 it begins to list the steps for troubleshooting a horizontal line.

Much appreciation for the knowledge and info, thanks! I'll try to repair the stock socket before the ebay socket's arrive, but I'll solder an ebay/machine pin socket to the LB when it gets here, and test all of the traces and connections on the Pin Matrix, that way. Then decide where to finally...
