Guess I should stop dragging my feet on getting the rest of the parts ordered soon.

Looks like the chips finally arrived in Canada, according to the tracking.

I have sent so many SMT parts to Narnia while working with them. Last project I ended up needing to place a second order for more, so this time I’m going to buy way too many extras.

I believe some cheaper USB-MIDI cables drop SysEx messages. I have the Roland cable myself though and it works well.

Does it even matter for modern drives? My understanding was that after a certain point, drives only really spoke LBA, and CHS values should just be maxed out to get as much of the drive usable as possible.

Thanks. For some of the ceramics I wasn’t really finding better than 10%, which seemed odd. I guess I’ll have to fiddle with my search parameters and try again.

I’ve spent some time looking through this thread, but haven’t found an answer. Is there a tolerance I should be sticking to for the capacitors (and to a lesser extent, the resistors)? I didn’t see anything mentioned in the BOM, and I couldn’t find anything in the thread, though I may have missed it …

Alright, here we go. This CSV BOM includes everything minus the IW78C21M1 chip, the DRAM chips, the optional components, and whatever the NotConnected resistors /would/ be. I think I found an issue with what you grabbed. For the amplifier, you have a TI TPA152DR, but that seems to have a completely …

I recently picked up a desktop that turned out to belong to DEC’s legal department as they were merging with Compaq. I kinda wish it had more, but there was one Word document about documents that needed to be provided to the FTC and DOJ, which I found to be pretty neat to see.

Though, as you may have found out, their "Inquiry" service is pretty much useless, I've tried several times and it was always a complete waste of time, just "we don't have any stock". That’s my experience with everyone’s inquiry service. Either no response, or “sorry we have none”, but then they …

V is Volts, VDC is Volts - Direct Current. They’ll be functionally identical in this case. I usually buy Nichicon, but Panasonic also makes nice stuff.

Question related to latest discussion, is TL866+, SOP44 adapter and selecting 29F800 is enough to dump the IW7821M1 content? That would work, but if the chip is already installed in a card, I believe you can just run some software in ARGUS_final_doc.zip from the first post in this thread. EDIT: …
