Here is my step-by-step I'll keep near for later when I need to do this all again. I found a few hodge-podge threads and videos around, but nothing A to Z. All I knew was the 98 VF/4 I bought has a go-tek USB as opposed to a floppy. Note- No docs, no instructions could be found. Found this blurb in the Keysight forum apparently the guy claims the MP-F17W-H1 floppy connector is non standard, but then at a closer look the information he is providing appears contradictory, since the MP-F17W-H1 pin out he is providing is exactly the standard 34 pin floppy connector? Long story short, has anybody successfully replaced the 8751A floppy, either with another floppy model or a floppy emulator? What would it take? I've replaced a gazillion of floppy drives of al kinds before, including with 720k DD emulator, but never saw such a stubborn unit.Short reference on what it took to get the Haas w/ go-tek USB floppy emulator reading the files on my USB stick AND then transferring them onto the Haas itself. I thought the 34 pin floppy connector is standard, apparently not so. In all cases, the floppy is powered up correctly from the separate 4 pin connector. Got a Gotek 1.44 floppy emulator from Amazon, configured for SEL-0, same light timing, same error. No good, when attempting to format, the floppy ight comes up a few seconds, then the 8751 reports "hardware error". Having a few Sony 1.44 floppy drives around, I tried to replace after re-configuring for SEL-0 (the default was SEL-1). Fortunately replacing the floppy hardware is easy, bottom panel out, four nuts out and here falls into your lap. Searched all over the place, no documentation about this model to be found. Received the instrument in good condition and noted the floppy is not working properly, sometimes it will prompt "media is write protected", then after re-inserting the floppy "media corrupt", sometimes it formats (LIF or DOS) the floppy, sometimes fails randomly, clearly needs a replacement. Won an 8751A on EBay, for rather cheap, after a competitive auction. * Las Vegas NV, USA Miracles require 24-hour notice. * KOI8 Net The impossible we do immediately. They almost 100% sure have their guts spead around significant area by now. They are relatively small value ones (don't remember now - something likeġ0.47uF 5 or 6.3 mm diameter small caps) around digital filter chip but Yet - most of receiver related failures are caused by those capacitors. Of identical boards are there) as soon as you can hoping it is not too late Would've been also interesting if it is something newer that what I have inīTW, I recommend replacing all aluminum electrolytics on receiver boards (3 It is also interesting what version of main firmware do you have - it Price haven't seen any source for those EPROMs.
Share those EPROMs with Instrument Basic (Opt.02)?
