I got my first attempt at PCB designing back from PCBWay and it mostly works! I just submitted a V2 design to be made after realizing the unreliable behavior on one column of keys was because the Feather I'm using has the voltage from the LiPo socket routed there so you can monitor it, but in a...

The GitHub app really smooths things out for people not used to dealing with Git every day. Another thought for this information is an address snooper. For machines using ROM SIMMs it seems easy enough to get the address of the code being run, maybe you can do the same by clipping into ROM...

Nice. Looks like they used the BeagleBone's PRU which is similar but more capable than the Pico's PIOs. Pi Pico's are about the only Pi's you can regularly get your hands on right now, I have two on a USPS truck out for delivery today.

In theory, yes, if you can get your hands on a Raspberry Pi Pico or other RP2040-based board running CircuitPython. I made a script and PIO program to generate a classic mac 512x342 signal to use to test another program that converts that signal to 1024x768 VGA. Going by this diagram...

I didn't want to volunteer Eric for more work, but it could be a handy debugging tool to have a USB-SCSI bus sniffer or be able to replay transactions against development code.

I feel I've seen a dip in quality control since we lost The Steve. With the OS developers no longer living in mortal terror the amount of logged errors you see in Console on a healthy and idle system has exploded. I don't think jobs would have stood for a steady stream of "expected" errors, even...

I suspect that they're bit-banging out SCSI from the EZUSB chip(s) much like BlueSCSI, RaSCSI, and SCSI2SD do, just in reverse. The BlueSCSI hardware could probably be reprogrammed to pass SCSI data in & out the USB port if someone finds a good driver interface to copy. I don't think there is...

While pondering turning an Osborne 1 case into the sleeper gaming PC and whether to use the original CRT I realized that upgrading the keyboard to Bluetooth would be an easy first step. The Osborne keyboard doesn't have any brains, the cable just exposes the raw keyboard matrix making it super...

That looks like the resource forks are in AppleDouble format (https://en.wikipedia.org/wiki/AppleSingle_and_AppleDouble_formats). You'll need a modern-ish Mac with OSX to mount the UDF and then copy the files to a volume the old Mac can read.

I think you can do it with just Disk Utility's restore functionality. The PPC/Intel cross-over will be limited by which Intel systems (if any) support booting from Apple Partition Map drives. I don't think OpenFirmware on any PPC Macs support booting from GPT partitioned drives. Carbon Copy...

ADC and Firewire.

The card doesn't really need to be able to deal with the full 32-bit, does it? The driver just needs to be tweaked to understand the 32-bit environment and make sure the card is allocated memory space and buffers that it can reach. It's the same sort of issue as using 8 or 16-bit ISA cards on...

Nah, the hardware flow control lines aren't level shifted and exposed on TheOldNet modem. Out of the box it's 300 buad 8/n/1 and is wired to be a RS232 device (DCE) not a computer (DTE). I usually use mine plugged straight into a USB-Serial adapter with no cables or adapters. You do need to...

Hmm. I wonder if you can use memtest86 or memtest86+ on that machine and maybe get better diagnostics of the RAM. Do the serial numbers all read the same when it reads everything as 512M?

Pentium MMX 233. The first set is in a full screen command.com within Windows 98. The second set to "reboot to DOS mode" with a little overhead. It seems that most of the time on this machine is coming from print the digits to the screen...

I saved some Apple fiber channel DAC cables from recycling back in the day. A pair of them fit nicely in a USPS flat rate box ($10). DM me if you're interested.

I'm pretty sure that all of the USB to PS/2 adapters out there are purely mechanical. The mouse does all of the protocol switching. Maybe you could cannibalize an older PS/2 wireless mouse receiver but all of those were much larger than the current tiny usb receivers. Bastarizing the IrDA port...

The RentWare didn't start until after CS6 and if my memory isn't completely faded I don't think CS6 phoned home to activate. It just did a pre-internet era license code validation. I remember the start of the RentWare clearly because we had to hold back on CS6 for a year or two before Adobe came...

hmm, doesn't look like sync is dropping, just the video signal. I suspect that there's a transistor or amplifier chip taking the TTL signal from the logic board and generating the power for the electron gun.

Like BlueSCSI or RaSCSI config tools to set image attachments or configure the WiFi on a RaSCSI.
