Thread: Another XT-IDE...

  1. #1

    Default Another XT-IDE...

    I stumbled across this XT-IDE from New Zealand while I was looking around eBay:

    Oh, look at that, he's managed to drop his price!

    These are based off my rev 4 design, this guy was buying the bare boards and building them up for a while. Bad choice on the EEPROM location, it won't work with the CF card mezzanine now.

    SuddenlyMatt is the first of the...well, I call them knockoff boards because originally they started as just the XT-IDE rev 4 layout with the project info and copyright removed. He's also the most aggressive Muntzer ("cost optimizer"). It does look like his may have a '245 buffer added back on, one of them lacked even the buffer at some point. Oh well, that's what some folks do when you release a project open source. I noticed that Monotech also has some of ejs's AdLib cards.

    What exactly is wrong with that board? I am very ignorant about the XT-IDE...

    It's a re-spin of a lo-tech board, minus the filter capacitors by the look of it.

    I ordered one (along with a V20 and a Dallas clock chip) for my Tandy 1000SX yesterday before I saw this thread, based on your video.

    The trouble with no bypass caps is that it'll likely work for some time (I'm assuming he actually tests the things before selling), but there's a good chance it'll have long-term issues as the chips age in, or if you plug it into a system with noisy power rails. I've already had folks buy XT-IDE boards and kits who had bought SuddenlyMatt products that worked for a while. I hear SuddenlyMatt will indeed replace them if they break, I guess that's a plus.

    The card with no data bus buffering at all was a real design blunder. CF cards aren't meant to drive the entire ISA bus directly. Even the folks hacking them onto the little RC2014 bus found that you really do need bus buffering.
