That bodge wire is from factory.

Here is a comprehensive PDF guide I put together that will be useful for anyone wishing to take apart their Quicktake 100 or 150 for recapping. I am maintaining a BOM on Mouser. I wasn't sure if this should be an Article or Document, hopefully I made the right choice.

Have you recapped the analog board yet? I’ve seen that when I had a poor flyback anode connection to the CRT.

Please don’t hot plug SCSI devices - it’s not designed for that and you could do serious damage. BlueSCSI won’t run off the back of a PowerBook as it doesn’t provide the termination power needed. You might be able to plug in a USB cable to provide power that way?

Looks like it has pads to take up to a total of 3MB.

If it’s not the stock drive you’re using, maybe the voltages are too low from the pin header? The next thing to try would be another LED, I guess.

Just to say, as an IWII owner I’m very excited to see this project in development. Is the plan to combine the features of both the AppleTalk card and the memory expansion card that were originally available?

Better than a logic board fault, I’d say!

The sound issue might just be a bad connection to the internal speaker. The design the IIsi uses - sprung contacts under the logic board - is notorious for being flaky. Try inspecting and cleaning the contacts as well as the pads on the logic board which press against them.

It’s entirely possible but a big undertaking, not sure who out there would be interested in designing such a card. In the meantime, if you have a Rev. 2 Personality card, you already have an unpopulated USB footprint that can be added on to :) It seems that Apple had planned to have this...

I’ve fixed another 840AV board! It was in such appalling condition, having been ravaged by the worst cap corrosion I’ve ever seen plus some nasty battery leakage on top of that. It’s taken most of the year, but not 5 years like @Mac84 :D I’d previously recapped it, desoldered/cleaned/replaced...

I used an old Lindy serial cable to make my loopback plugs and I assumed that the wiring colour coding was in the same configuration as @Elemenoh showed. Unfortunately, it’s not - so I don’t think we can conclude the colour scheme is standardized. Or, perhaps it is, but not all cables comply.

As far as I know there is an issue using the 4 port 3114 in a Mac… I don’t remember specifically what it is but I don’t think the full support is there. EDIT: Ah yes, it’s not OS 9 compatible. If you’re just using OS X then no issues.

I’d really suggest that anyone serious about using an SSD drive in a Blue and White get hold of a SiI3112 based PCI SATA card and flash it with the firmware modded by @dosdude1 and available here. I say this because these cards are cheap to pick up (about $10 on eBay), will avoid having to deal...

I've assembled a few of these RTCs. Orienting them is a bit of a problem, pin 1 (with the square pad) faces the PDS slot. I've applied a stripe of white paint to the edge of my PCBs to aid with this. The oscillator can remain on the board, but you *must* remove the PRAM battery if it's fitted.

Useful to see a pic of this thing. Where is R726 located on the board? To be clear, for a successful boot: do you also need to disconnect the analog board from the PSU… or just the internal video cable from the Wings card?

I very likely have some spares that I could send you for the cost of postage. Where are you located?

Do it ;)

I’ve made a couple, the results were alright but not spectacular. I get a bit over an hour’s runtime on average but weirdly one seems to work better than the other, and they don’t always fully charge up.

Congratulations! The black screen is bad caps on the LCD driver board, that is for certain. I wouldn’t try using that battery again - it’s definitely dead and might blow a fuse on the logic board. Instead, pop the sliding cover off and use it to cover the battery bay.
