Was it green? If so, no, i'll send you out a new one - Rev 1.4c is the latest.

The last couple of weeks have been intense at work and my mental health has been poor so progress has been slower than I like. I’ve made decent headway on the passives though...

To show how serious i am about this project...I just bought a working 200MHz, 96 channel logic analyzer from eBay - comes with all 4 Pods, 14/16/18/20 pin DIP analyzer clips, 40 and 48 pin DIP clips and literally every probe going - i even have the floppies in the bag. I've already ordered a Gotek floppy replacement and i have an image of all the disks needed to work it. CRT is crisp as hell, bright, no burn-in. I'm also bidding on a Tektronix Oscilloscope and a hot air station for the SE/30 stuff moving forward. I am 100% COMMITTED to making a working one in the next 12 months, and I have every hope that Rev 1.4c is the final version...

Like we needed proof of your dedication?

Well you know, taking a break can sometimes reduce interest in a project...

Even if you just get binary read-outs it's a great help. I've got a 2ch/16 bit Agilent MSO (an old one), and in some cases it's been a fantastic help, but TBH 16 bit just doesn't cut it for 68k systems. I've got at least one reversing project that's stranded on lack of logic analyzer channels, so I'm a little jealous of what you've got.

Well, if you want to undertake the reverse engineering of the SE customs - you're welcome to take the analyzer

I've been following (lurking) this project for a while and decided to create an account to say that this is a really worthwhile effort. I'd love to see similar undertakings for other 68K systems.

Just out of curiosity: if you're going to be cloning the SWIM chip, would it be possible to make it so you can daisy-chain floppy drives like you can on the Apple II? I don't know if there are other hardware limitations, or if it could be implemented via the SWIM chip.

I assume repopulating your latest PCB didnt work?

@techknight I've not even started yet - between heart issues and easing back into work again, i've just not had the chance. Ie - on Saturday, I slept for 12 hours straight - i will give it a go this coming weekend though...

Oh wow. I am sorry to hear that has happened. Hopefully you get well soon and not catch this corona nastiness in the process, wish you the best

If making a custom PCB, it would be interesting to make a SWIM that works with standard IBM floppy drives instead. And/or even IDE hard disks. IMHO more valuable to the future of retromaccing than making a 1:1 SWIM. But! Do whatever is most fun!
p.s: Sorry to hear about health issues! Hope you feel better soon!!
