The every other frame notion is a worst case, last resort kinda deal. Spitballing every nasty approach I can possibly come up with here. ;) Vampire Video in the IIsi is a well and truly diabolical affair: - was wondering about bit-banging the DRAM frame buffer to do an end run around RBV...

Looks like we might keep it digital on a IIsi board reload for SE/30? The video signals are generated by the Apple custom RAM-Based Video (RBV) chip and are driven through a combination color lookup table (CLUT) and video digital to analog converter (VDAC) chip. Each monitor identifies itself...

Old project, wondering where it has gone. Full feature set here. Features CRT and LCD display support 24bit Standard VGA interface Separate VSYNC/HSYNC and combined CSYNC synchronization signals Composite BLANK signal TripleDisplay support 12bit Interface Compatible with DVI transmitters and...

:ROFLMAO: No power jack, no problem . . . TwinSlot fitment prototype of paper and cardboard laminated with flammable adhesives sitting in the PCI slot of an Alchemy/Gazelle machine that might be fired up however . . . :eek:

Caffeine is finally kicking in. :confused: Time shift can only be achieved by dropping every other frame? Would this induce unacceptable flicker? Wouldn't work on an LCD, but such wouldn't be required as it's digital to digital, no DACRAM timewarp required. However, phosphor latency of CRT...

Don't wanna tangentially muck up the fabulous IIsi into SE/30 thread that @zigzagjoe has running over at the MLA with this craziness. @Bolle posted parameters of the conversion problem. _______________________________________________________________________________ The Apple 12" 512x384 video...

@wottle what no eyebrows? :p

. . . one piece at a time! :p /JohnnyCash Tucked everything away and started looking for missing bits of a PowerBook 165c. I'm trying to get it back together to finally test after I snagged it for the MacAntFarm™ project two decades ago. I'd already acquired a couple of victims for that...

Looks like PowerBook 100 batteries are only 6V, so I guess the new build batteries from @360alaska are out of the picture. :confused: Unless someone chimes in with a better idea, I'll just go ahead with current limiting resistors on a thin PicoPSU I found today for the time being. Still...

Well that didn't take a lot of research! Looks like I should be able to desolder the "internal" HDMI connector and replace it with the cable connector from this board! 😀 Looks to be fine in the component placement pics above. But should this plug card protrude too far out of the HDD cubic...

A Contemporary 21" CRT sitting center stage beside a 5x00 would make a very nice setup. ;)

Settling into waiting (impatiently) for components to arrive mode again. After all these years in process I should really be more patient. :rolleyes: Component placement experimentation: The PCIe adapter for M.2 fits into the metal case for my setup, but is about a quarter inch too tall...

Very interesting, reminiscent of Virtual Desktop features of early VidCards supporting far higher resolutions than their RAMDAC and contemporary displays could support. What's the highest resolution that card can support on its external connector?

. . . yet again as once more, this is way above my pay grade. :oops: When spec required 5V for LCD and 12V for Pi/CM4 board, notion was to use a PicoPSU and its AC adapter. Figured I only needed current limiting resistors for those two Pico lines. Now I only need 12V input for both, which...

@Drake developed the perfect interface for the PowerBook 100 Trackball: https://tinkerdifferent.com/resources/adb-usb-keyboard-mouse-adapter-firmware.26/ @RolandJuno over at the MLA picked up where I left off on development of the Portable's peripherals...

Thanks guys! 🙂 PicoPSU discussion here: https://68kmla.org/bb/index.php?threads/picopsu-is-waste-heat-proportional-to-current-used.49529/post-557442 Still need to locate the 1400c KBD adapted base, just love that heavy use patina of BabyPB contrasted with the 1400c KBD. Found the lid with...

PowerBook 100/2300c LCD/Logic board upgrade has been in process for well over a decade. This revision has been on the back burner since the Compute Module 4 first came out. The I/O board makes it perfect for this upgrade of my beloved BabyPB, very first laptop, bought new and maxed out in the...

I did a nice workup years back at the MLA, but I think actual content was lost in the great pixel robbery. https://68kmla.org/bb/index.php?threads/powercd-base-unit-teardown-pics.18975/ Lots of people tried hooking a SCSI cable up to the most definitely non-SCSI DB-25 interface of the flying...

I realize drivers would be the issue, just curious about backward compatibility of 040 PDS? That's assuming the Rocket's Daughtercard Interface is as simple as that?
