    Announcing ZuluIDE - an ATAPI CD-ROM and Removable (read-write) media emulator

    That may be true, however you don't need to physically possess a ZuluSCSI board in order to reverse engineer it, particularly when the pinout of the RP2040 and the pinout of the Pi Pico are both known quantities. We're talking about a two-layer board here, and there are only so many signals...

    Announcing ZuluIDE - an ATAPI CD-ROM and Removable (read-write) media emulator

    It's just not that simple. ZuluSCSI was licensed under the GPL because it makes use of the now-decade-old SCSI2SD command handling library. That code is licensed under GPLv3, and if you know anything about how the mechanics of the standard GPL license works, all derivative works must also be...

    Announcing ZuluIDE - an ATAPI CD-ROM and Removable (read-write) media emulator

    Right, and ZuluIDE is by no means a replacement for a SATA controller. Commodity IDE to SATA adapters are cheap and plentiful, but they only allow for non-ATAPI (rigid disk) emulation. By simply copying ISOs and/or bin/cue files to your SD card.

    Announcing ZuluIDE - an ATAPI CD-ROM and Removable (read-write) media emulator

    I don't really understand this mentality at all, since it would appear that you've been deceived, and are not aware that the BlueSCSI V2 firmware is a straight rebranded derivative/fork of ZuluSCSI RP2040, then. It was publicly revealed a mere 70 days after ZuluSCSI RP2040 was made available for...

    Announcing ZuluIDE - an ATAPI CD-ROM and Removable (read-write) media emulator

    Rabbit Hole Computing, my company, has been working on such a thing quietly for the last year and a half. While it isn't 100% ready for prime time, it is available for those who wish to help improve the product. ZuluIDE is powered by an RP2040 microcontroller, in concert with a small Lattice...

    SCSI2SD question

    And now there's a kit-based variant of ZuluSCSI RP2040, ZuluSCSI Compact Homebrew that costs even less ZuluSCSI RP2040 delivers up to 9.5MB/sec of throughput on reads, and around 6MB/sec for writes, significantly faster than the SCSI2SD V5 family, at a lower price point.

    Where are all the SCSI2SD devices? Is this because of the chip shortage?

    Hi, there, have you reported any of those issues to Rabbit Hole Comuting? Which firmware version are are you using? Don't be so quick to dismiss a product that's young, when it was designed to be firmware-upgradable. Engage with the manufacturer!

    In search of any working DBA ESDI drive for PS/2 Model 55

    Does anyone here happen to have any DBA ESDI they're no longer in need of, or would be willing to sell? I'm in northern California, and just picked up a PS/2 Model 55. I'm also looking for two 4MB 72-pin SIMMs (80ns) suitable for use in this machine, as it only came with one 2MB SIMM. Even one...

    Monochrome DEC Rainbow keyboard and video cabling options

    I picked up a DEC Rainbow PC100-B2 for free at this most recent VCF West show, and it has a 10MB MFM HDD, no color video option, and no cables of any sort. I've got DB15 video cables I can hack up, and I understand this thing can output monochrome composite video. I have a couple of displays...

    Troubleshooting Compaq Portable III power supply failure

    Hey folks, I picked up a Compaq Portable III at VCF West this past weekend, and it came with a bad power supply. If I power it on with no load, the built-in fan powers up, but none of the DC output voltages are anywhere close to correct. If I power it on with a load, it sits there and ticks...
