I have two IIsi machines, when I use a BMoW ROMinator II I get instant death chimes on both machines. I also get instant death chimes when I use a Kero's Mac Mods ROM SIM loaded with System 7.1.0. I can boot both machines into System 7.1 using a BlueSCSI, no optional RAM or ROM SIM. I can...

Thank you everyone, I used Alex Labs DB-15 to VGA adapter and after toying with a few different monitors I got this to work.

Is it possible to get VGA video out from a stock IIsi? I’ve tried a DB15 to VGA adapter on multiple LCD monitors without success. What’s the trick here? Alternatively, I have a RGBtoHDMI; maybe this is a better option?

I wonder if it could be VRAM (or VRAM related traces).

I probably don't use mine as much as @Elemenoh but this has been my experience as well.

Those vintage computer shops in SF must be a best kept secret. You can’t find even retro video games stores here.

What’s the next step to having the image interpreted into something actionable - is there a particular community we could offer a bounty to?

@ScutBoy made a brainstorm available for decapping and imaging in collaboration with @MacEffects. Kay recently sent his faulty brainstorm to me. Let's see if there's any progress which can be offered from the decapping images; I'm not really convinced there's much more I can offer with the...

It's been a minute. How about I release the Solidworks CAD files and we see how far the community can run with it?

Yes, but my preliminary testing highlighted that I had produced costly trash.

I ended up purchasing one of these so that I can no longer need to have a Hakko FR-301 obnoxiously buzzing a foot or less from my face while working — I can put the Metcal pump unit below my desk on a concrete patio paver to further deaden transmission. Mine came with the filters but I imagine...

I've already tried this. Once for an hour (which had little to no effect) and a second time for 24+ hours. After the second attempt the drive will spin up, click a little, and then spin down with no further activity.

As the title says, I have an unresponsive Quantum ProDrive ELS. This drive is from my family's 1993 LC 520 and has a lot of old school projects and silly doodles on it. As a result, I'm interested in restoring the information. I see there's a spacer available on eBay for this specific drive. I...

Head alignment on the Famicom Disk System drive is mission critical. Also, the level of tolerance for head calibration is minuscule at 50 micrometers (0.05mm). In my search to simplify and quantify this calibration process I have developed several techniques. However, I believe my newest...

They’re kind of annoying to open up - inside you’ll find a handful of small electrolytic capacitors. I haven’t heard of these cameras needing to be recapped, which makes sense to me - relatively low voltage and very little heat build up. You’re probably better leaving it alone.

Totally an option. A few considerations that come to mind: Some analog boards may be in need of repair and the fan could cause stress on an already strained system. I believe I’ve read in the past that fans can introduce interference to early power supplies but that is entirely anecdotal at...

Adding the pass through power switch is trivial - it’s just a power cable cut in two with a switch in between. Using a 12v fan adds the requirement for a small (e.g., 150mA) power supply. The module will block some of the air flow but I don’t believe it will have a significant decrease in...
