Is this the unicorn cable the Portrait display needs? That caught my eye when I was glancing at the cable heaps at a local computer store. I think it's in the $2 cable bin.

Project A.D.D.: Z80/8088, G4, G4, Pentium MMX, and some photography stuff

Sorry, no. My G4 tower got battery bombed and doesn't power up any more. That error message looks like a coding bug though, not something that can be fixed without recompiling Xorg.

https://lists.freedesktop.org/archives/dri-devel/2022-January/338356.html The bounds checking for reading the card's ROM cut off the last byte. I think in every other case that isn't a problem because the ROM image is a full power of two dump of a flash chip, so the last byte is never used, but...

A GeForce 2MX will probably fail with an unresponsive screen with the Adelie 1.0-rc2 released images because of an off-by-one error in the nouveau driver that probably only effects OpenFirmware Macs. Adding modprobe.blacklist=nouveau modprobe.blacklist=nvidia to the kernel command line in grub...

Progress! After lots and lots of staring at hand written schematics and removing components starting from the output pins I found two ICs that were failed-short. An "8UV48A" power transistor and a "FE16C" common cathode diode array, and the main circuit breaker I took apart to look for damage...

Hmm, interesting. I suspect it would work but you'd have the downside of any computer you plug in trying to use the display part.

I think you just need to flip your TX and RX pins on either end. DE9#2 should go to DIN5#4 and DE9#3 to DIN5#2. Serial is notorious for this confusion. One end of the connections TX needs to connect to the other end's RX(RD) and vice versa. Connecting TX to TX gets you Twitter: both ends...

Both CPUs can access the floppies. The floppy controller is the only thing attached to the Z80 bus and the 8088 has to talk to the Z80 in order to access it. Some sort of shared memory shenanigans.

I scored this historical oddity today. 1983 dual-processor (8088 and a Z80), 256k of RAM, dual 400k 5.25" floppy slots sharing a single drive motor, a 10MB HDD, and 12" monochrome CRT. Oh baby. While taking it apart to clean and inspect I discovered that it was a completely tool-less and modular...

The dreampi would probably easiest. a Cisco/Linksys/Sipura SPA122, SPA2102, or larger model should do the job with any devices with a little configuration. The Cisco ATA 186's are "real" Cisco devices so the configuration will be different and possibly have silly Cisco license restrictions. The...

I, for one, welcome our new cap soldering overlords
