Thanks, I’ve ordered a Netgear EN104 hub from ebay which has 4 RJ45 ports in the front and a BNC coax plug in the back. Should be here next week sometime. It was GBP £69.95. I’ll need to get some BNC T connectors and some terminators I guess. The joys of 1980/90s ethernet! :D

Thanks both - I just installed the card and booted up 7.5.5 and all seemed to start as normal. I then found the Asante Troubleshooter v 1.9.0 and ran it. It detected the card in slot 9 and says “Memory Test Passed”, “NIC Test Passed” and “No response from other Macintish” which seems...

Please excuse my ignorance but ”during installation” of what exactly if the drivers are part of System 7? Do you mean during installation of System 7 itself or do I need some other software? Thanks.

Hi, I‘ve got one of these cards in my restored SE/30. Can you please tell me where I can get the drivers for it? Thanks.

@timtiger to test the 1Hz pulse, you just need to use the multimeter in DC (not AC) mode and in a voltage range greater than 5V. The multimeter will tend to react quite slowly so you might see it switch between around 4 volts and 1 volts. The important thing isn’t the voltage but the fact it...

Haha, no worries. I hope you didn't mind me asking this but I've learned that it's often better to ask a silly question than not to. I kinda wish it was just the brightness, both for the entertainment value and the fact it's an easy fix! :D I hope you find the cause - let us know if you do. 🤞

Well done! Looks like a nice clean SE/30. Enjoy!

I'm sure this is a silly question but have you tried adjusting the brightness control? I don't mean the various adjusters which are only accessible when the case is removed, I mean the control which is accessible from the front of the machine just underneath the CRT bezel.

A couple of suggestions. If you can get Snooper installed ( https://macintoshgarden.org/apps/snooper-20 ) try using the PRAMand clock test on it to test your RTC. Also, if you haven't tried already, try putting your multimeter on RTC pin 1 and see if you get a 1Hz pulse.

@daanvdl after seeing your reply I went back to some old photos I took of my boards before I commenced repairs and actually mine also had the 4MHz parts installed originally. But it is definitely the 6MHz part which is installed and fully working on my "reloaded" board and I can confirm it...

That's a good question and I'm not 100% sure of the answer but the chip part number on my board is a Z0853006VSG which I think means it's a 6MHz part. You can get a pretty detailed data sheet from here: https://www.digchip.com/datasheets/parts/datasheet/542/Z8530-pdf.php so you should be able to...

Nice work! Enjoy!

Just to take another variable out of the above equations, I can confirm that Snooper will work as long as you bridge pins 1 to 2 and 3 to 5 in both modem and printer ports when testing. No need to bridge any other pins. Pins 1 and 2 are the two pins in the bottom layer and pins 3 and 5 are the...

You might be thinking about MacTest SE/30 although I've not managed to get it working since it requires a SCSI loopback device as well as a serial loopback cable. What I've been using is Snooper which can test individual ports (modem or printer) by looping pins 1 to 2 and 3 to 5 inside the port...

Wow, 25 minute response time - not bad! :geek: Happy to confirm I've reversed my lines and Snooper now reports no problems at all! Happy days! Seems an appropriate time to post photos of my finished board both with and without the socketed chips and also showing my printer port rework and...

@Bolle and anyone who is building or about to order PCBs for SE/30 Reloaded, I think there is a very minor PCB error which affects the printer port. On the schematic (original and remastered) the following traces are specified: RP3 pin 13 to UD12 pin 14 RP3 pin 14 to UD12 pin 13 However, on...

Yeah and it looks like they also ship to the UK. Total price for 8x16MB SIMMs shipped to the UK is $103.58 compared to $137.72 for Keystron. That's a decent saving. I can't quite make out the chip part number but there are certainly 8 of them instead of 2 with the Keystron module. I wonder if...

It seems to me that they are applying a "common sense" approach to provide a product that is in demand but which otherwise would have cost driven up and/or supply restricted due to the lack of suitable 5V DRAM chips. I wouldn't expect them to advertise the fact that they are using 3.3V parts but...

I've had a reply from Keystron already and although I don't want to directly quote the guy since I don't have permission, I can paraphrase a few points: 1. He doesn't deny that they are using 3.3V chips 2. He says they tested these 3.3V chips from various manufacturers many years ago and found...

Oh well, it's too late to cancel the order now. I could have gone with Memory Masters or Keystron but IIRC Memory Masters were charging twice as much for delivery and had a slightly poorer feedback rating than Keystron. Thinking about the issue of running over voltage, I wonder just how much of...
