In require of a floppy controller for a 286 he was operating on, [Gadget Reboot] took to GitHub to see what was available in the open components area. There he discovered an ISA board capable of managing up to eight drives from [Sergey Kiselev] termed the Monster Floppy Disk Controller (FDC) — arguably overkill for the activity, but far too impressive to pass up. Luckily for us for us, he made the decision to doc the build process in a video that covers everything from ordering the boards to configuring the BIOS.
The video commences with a high-degree overview of the schematic, which as you could possibly have guessed, in essence places two equivalent floppy controllers on the same board. You can convey to this structure was place jointly throughout the present chip lack, as [Sergey] was very careful to contain some wiggle home if specific parts grew to become unavailable and experienced to be swapped out for the options shown in the BOM. It is a determination that now paid off for [Gadget Reboot], as in some cases he had to go with the 2nd-alternative ICs.
[Gadget Reboot] was in for one thing of a surprise when he submitted the board for fabrication, as deciding on the selection for gold contacts on the edge connector made the creation price tag soar from $5 to nearly $300. He information how he was equipped to provide that cost back again down a bit, but it however ended up being a lot more than 10 instances as pricey as the base cost.
The 2nd fifty percent of the movie is committed to configuring the Monster FDC, which will certainly be a valuable resource for anyone looking to set this board to operate in their personal program. [Gadget Reboot] demonstrates utilizing the board with “only” four floppy drives, and every little thing appears to be like to get the job done pretty effectively.
Of course if your desires aren’t pretty so grandiose, we have viewed some more expedient floppy controllers which may possibly be closer to what you are seeking for.
Thanks to [AnotherMaker] for the tip.
