The diffuser is many layers. The acrylic panel behind those is the lightguide (and should be fine). That looks like liquid/mold damage. It's possible to buy replacements, or just salvage them from scrap LCDs. Careful handling with gloves is necessary - skin oils and any abrasion will cause...

I've been very lazy to finish and test my designs, but maybe now this one will be done.

Not only schematics but it seems a disk (and ROM?) dump too?

The funny thing to me is that they try and make a ceramic chip look like epoxy, with that textured top. Try and wipe it with some acetone. Sometimes the original markings are still readable. It could be a 33MHz part, just an older mask.

First number called out is typically the capacitance - in this case, 33uF.

It could be the opposite like you said. I haven't looked at that datasheet in a good while. Hm. Indeed. It's a value that can be experimentally obtained, though. If I solidly characterized that value, and it met spec, then I'd have no qualms using that. Realistically since we're dealing with...

It does. Which is why this is a non-issue 99.99% of the time (and the bus can cope with the 00.01% where it isn't). That works for lots of cases, but then I'm also creating a filter on each line. I'd need to think more about the implementation. I didn't have a lot of time to think and prototype...

Thanks - I did try and pay attention to the layout, and did everything I could to keep it reasonably clean. Indeed, SCSI is supposed to be open drain, and each line must be able to sink 48mA. So I'm somewhat violating the spec twofold here - those buffers are only good for 32mA (but they can...

Greeeeat. *sigh*, fine, I'll do it when I yank the LCS to reseal that too.

My bad, not an intentional omission - I honestly expected myself to write my own SDE code at some point, but I keep being forced to realize I am not really a SW guy.

The bad panels are 640*400. That limits somewhat-direct swaps. It also complicates swapping in something else - we'd need new bezels, a 1280*800 LVDS panel, and an FPGA inbetween machine and panel. Replicating any moderately big LCD is outrageously expensive - I've begun doing that for a...

Hosiden is a very large company. They also have exited the LCD business over two decades ago.

I've now uploaded the reshaped version.

There we go - I'll upload this alongside the old version on github juuust in case. @croissantking may I use your image of the filed-down install to explain the reason for this? I'm not sure it'll fit as my 8100 board exists without a case, and I don't have an 840av at all, but... It should be an...
