I get a black screen of nothing if I try. The system boots and runs normally (well, I am chasing another problem with getting USB cards working but I don't know if this is connected). I have mashed the CUDA button plenty of times, reset PRAM, PRAM battery is working. The machine apparently...

Nobody's sourced any I don't think, but they crumble so badly and so often that there's gotta be a bunch of whole analog boards for them floating around.

People have been looking high and low for the original VIC-20 switch for decades and it seems fruitless now. I've never even seen it crop up in other equipment. I always liked the CR better, that use of a 120V shaver cord for a 9V connection has always irked me. Did that surplus site indicate a...

With the VIC-20 you can get new PCBs for a VIC-20CR motherboard, move all the chips over, and then 3d print a new side plate, upgrading around the power switch problem (VIC-20CR uses the same power switch and power supply as the C64).

Amiga 060 accelerators typically have a tiny ROM that patches things enough for Kickstart to work. Some of the newer designs skip this and need a patched/post-3.1 version of Kickstart.

Amiga PiStorm 32 doesn't have fully working MMU BTW. Neither does the Vampire. The devs just can't be botha'd. Kinda makes it a non-starter for MacOS. I have some experience with 060 on Atari and that's mostly fine since the Falcon breaks so much ST software anyway. I know of people trying to...

It should be possible to create a more accurate version of the button just by integrating the button piece from a 8100/800/etc style bezel model. Also, would it be possible to do a model for the tray-loading CD drives? Originals are hard to come by,

R129 and R130 are swapped on the diagram. Pulling R129 got me a Machine ID of 63 - the gestalt ID of the “unreleased 33 mhz WLCD derivative”. Here’s hoping it’ll be stable.

Pulling R137 just makes it think it's a Quadra 610 (Gestalt 53), changing R130 to1.2K doesn't make any kind of difference. Ideally I'd want to change this machine's Gestalt ID to 63 in order to get the serial clock correct, but I don't know what resistors to pull/add for that.

There's a 300 ohm resistor already at R130. Do I leave that alone or change it for the 1.2K?

So if I pull R137 (300 ohm) and add R130 (1200 ohm) on a Centris 610 motherboard, 33mhz will be guaranteed stable? I'm dropping a 33 mhz full 040 into one here (without onboard ethernet) and I want to make sure it'll be guaranteed stable.

I don't see them on your store. Are you still able to source them? You're right about them being an odd unavailable size...

I pulled it off but they really suck to solder. Very very tight spacing and PLCC SMD shenanigans. I'm not sure how to make it less painful to build these adapters because they're sorely needed not just on computers but arcade games as well. Maybe some new design with a crazy 2-3 layer sandwich...

E-waste crackheds strike again! Yes, it's another cut cord monitor. This one's very, very painful to disassemble but here's what's left of the monitor cord: The monitor consists of 4 PCBs inside: a shockingly tiny neckboard, a power supply board, a deflection/HV board, and an input board. The...

Gonna try these next. Fingers crossed.

I can't use these gerbers in their current form. I found out the hard way: Impossible to upgrade the ROM and SWIM at the same time - which is the only reason you would ever want to upgrade the ROM in the first place. You could use some really tall pins so they miss each other, but then you...

I'm in the same boat with a Mac Plus motherboard. It's actually a little hard to find the exact socket used; it's got a little flange on the top and the socket entry point is a certain height above the PCB. That said I think this is it here...

Ordered a few and so far so good. Now I'm wondering if there's a similar solution for 68-50. Anyone done a blank one of those?

Also consider taking a look at the MacRescue, which is a great candidate for cloning. Adds up to 6MB RAM (4+2mb ramdisk only) and the Mac Plus SCSI hardware. Just add Mac Plus ROMs. You could extend the design by adding a disable switch + ROM switcher, allowing the 128 to operate as originally...

I have here a Quadra 800 that *only* puts out sync on green no matter what adapter I use. I also have a iisi here and that will put out csync on the hsync line if I configure the adapter right. That same adapter, configured identically, is not putting out sync on the sync lines when plugged into...
