I'm imagining a 'two box' PowerBook with the top and bottom cases sitting separately on a desk :D Best of luck! I'm a bit terrified of having that happen to my 180c any time I open it up. Certainly still possible to repair, but a bit of a pain for sure. Good on you for giving it a go.

SEthernet/30 cards all made up and ready to go out to beta testers this week!

Ooooh, I'd heard of that - apparently someone wrote a whole Usenet reader in Hypercard with it! Hadn't actually come across a copy though; might be interesting to play with. Thanks!

The only way to know for sure if the interconnect cable is good is to test every single pin - it only takes one broken connection for problems to occur - and even then the fault can be intermittent.

Huh! That would make sense, I suppose. I took a closer look at the rise time on my own card, and it's also pretty marginal. In my case it was easy enough to add a 'fixup' state to drive DSACK high between being deselected and /AS next going low. Very glad I switched to a CPLD for my glue logic!

Spoke a little bit too soon about getting the ColorBoard working - the rise time issues are only half of the story, it also appears to be holding DSACK asserted for too long as well. Most of the time, my fast rise-time hack was enough to make it work, but in some cases, the ColorBoard was still...

I was lucky enough to get my hands on one of zigzagjoe's prototype boards and have a couple of notes to share. My main interest in getting my hands on one was to validate my ethernet card with it - on that front, I'm happy to say that it works really well, and the faster processor does wonders...

Yeah, this is unfortunately one of the great frustrations of working with vintage Macs - unless you have another newer vintage Mac, getting files to and from them is a bit of a chore - especially with machines like the Plus, which can't even exchange floppy disks with non-Macs. The most...

You could use Mini vMac instead of Basilisk II - Mini vMac emulates a Plus specifically. However, the Plus is supported up to Mac OS 7.5.5, so you should be able to use a newer OS (although I'd argue that 6.0.8 and earlier is the sweet spot for the Plus - later OSes make it feel a lot slower)

While I’m not an expert on the Quadras, in my experience, slow boot times are a bit of a fact of life when you’ve got lots of RAM in an older Mac - at each cold boot it all gets tested, and the more RAM you’ve got, the longer it takes - and it’ll just sit there not showing much in the way of...

Yeah, I made it taller so that it could reach the card retainer on the SE/30 chassis - with the extra weight of a card in the pass-through slot on top, I wanted the additional mechanical support. It's still smaller than the "legal" minimum size for an SE/30 card though :) That's correct; I've...

Haven't had much to update this thread with recently, but after boards and parts for another hardware revision arrived the other day, things are progressing nicely! The hardware bugs that I mentioned earlier in the thread were going to necessitate another board revision anyway, so I took the...

I'm genuinely in awe; what a great writeup too. Well done!

If you're doing it in good faith? Doesn't bother me. Sometimes people misread things, or simply forget. Even if it does upset you, it costs you nothing to ignore it instead of coming out swinging. It's not exactly doing anybody any harm. Not sure what forum cultures you're coming from, but in...

You've come in here out of the blue and been nothing but rude and condescending. Your literal second post on this thread was to berate somebody for innocently offering advice. I don't know what kind of treatment you expected, but with the attitude you've shown so far, I don't think it should...

I've been working on new ethernet hardware and an accompanying driver - the hardware is still in early-prototype stage, but the driver is more or less complete and functional: https://github.com/rhalkyard/SEthernet/ Ethernet drivers are slightly weird in terms of their driver interface (they...

One other thing I just thought of in favour of using the drivers that came with the card - they will usually also include some kind of diagnostic application on the disk, that only works with their specific driver. If you ever end up having to troubleshoot networking issues, sometimes those...

Those "works without drivers" ethernet cards are usually clones of the original Apple EtherTalk NB card, however most of them usually have more onboard buffer memory than the 16 KB that the Apple card came with - from a quick bit of research, it looks like your card has 64KB. They'll work fine...
