A Greaseweazle costs like $35.
That being said, it's always fun to hack around using the tools you have lying around. Put money already spent to good use.
- vbezhenar 2y agoThere are much cheaper logic analyzers out there.
- snvzz 2y agoI would suggest as the starting point to look at sigrok's supported hardware table[0]. I personally own a bunch of the cheap 8ch 24Msps saleae clones, which are typically below $10. I would recommend the one from muselab as it has open sourced its design. The next step, the DSLogic, of which I have a 200Msps 16ch model. 0. https://sigrok.org/wiki/Supported_hardware https://sigrok.org/wiki/Supported_hardware
- userbinator 2y agoI would recommend the one from muselab as it has open sourced its design. The original Saleae, USBee AX, etc. are basically the Cypress FX2 reference design.
- nine_k 2y agoIf you already have a logic analyzer, are interested in the details, and maybe are facing a tricky disk with physical damage or creative copy protection, TFA may be helpful. If you just need to read disks without hassle and expense, a Greaseweasle or another adapter us likely a more suitable choice.

- hi-v-rocknroll 2y agoYep. I have a Greaseweazle and a Central Point Copy II PC Deluxe Option Board (and regular). Greaseweazle is largely the way to go. It's important to use the highest-fidelity method on the best FDD with the highest SNR because using a floppy disk causes wear to the media. Age also plays a factor. I also have TEAC (2.88M, 1.44M, 1.2M, 720K, 360K, and SCSI versions), Sony, and various other FDDs.
- dazhbog 2y agoI remember it used to be $200 for a Saleae logic 8. Their margins on that hardware are insane..
- Palomides 2y agoyou're really paying for the software, imo
- daneel_w 2y agoAs a great alternative there are a handful of very cheap Saleae knock-offs using the same series of Cypress/Infineon logic chips, and they work well with e.g. Sigrok.
- kees99 2y agoVery cheap knock-offs have same CY7C68013 usb interface chip, but lack an FPGA that original Saleae has, so can't capture quite as fast. Plenty fast enough for a floppy bit-stream, of course.
- ndiddy 2y agoNote that the knock-offs are clones of the original ~10 year old Salae Logic design, which also used the CY7C68013 without an FPGA (and had smaller margins than their current design, it only cost ~$100). They added the FPGA as a way of differentiating their products from the clones after they started becoming widespread.
