ELSA Erazor X² arrived safely. Supposed to have 2D issues, ghosting in higher Windows resolutions. Possibly an easy fix of a single discrete component, if one can find it.

I've had a GF256 that has the output ghosting problem, and I've talked with several others who have the same issue with theirs. There isn't much going on in the VGA output circuit so far as I could tell, just the source termination, diodes (probably for ESD protection), and output filter inductor+caps. My thought is that VGA DAC output degradation is endemic to the GF256 GPU chip itself but if you figure something out, I'd love to know! Best of luck!

Thanks!
Chances are, it really only occurs at highest frequencies of modern screens and not with any real-world resolutions of appropriate games.
Also, I'd very much assume that the issue does not apply to the DVI out, if in place, unlike here.
Obviously much less collectible that way, including the modified cooler, but as a toy?
Anyhow, with my very limited skills, I shall cross reference my Gloria II cards who should be all but identical.

Edit: While the main semiconductor should be pretty much the same, the Gloria II layout is actually quite a bit different, not just the AGP pro interface.

I like jumpers.

Bought myself a little obscurity recently and it arrived today -

A Sharp MZ-700 computer from 1982. The seller has already cleaned it up and recapped the power supply, which is great!

Not the most highly specced or capable computer of all time, it was already outdated & overpriced by the time it got released in 1982. But a nice curiosity to have in my collection.

Came with a bunch of cassettes with games and applications. As well as the paper and 2 sets of ink pens for the built-in plotter:

The model with the built-in plotter is rare enough to come up for sale, even rarer with a complete set of paper & pens. No idea if they even work, but I think I'm probably hesitant to use them up in case I can't find replacements.

And of course, I had to load up some software on it to test -

Found a use for an old iPhone too, to load some games onto the MZ-700! 🤣

Who could resist the urge to buy 340 new floppy disks?
6 sealed 50u packs and 1 opened with 40 unused floppies inside.

This should be enough to back-up at least a single CDROM disk! 😋

I always jump on the new floppies when I can. They are getting rarer.

There's probably a market for somebody to figure out how to make small production runs of new floppy disks.

I flermmed the plootash just like you asked.

They were dirt cheap back then and I'm rather positive that some manufacturer kept some of the tooling for them, the injection molds at least. Just needs a marked. But even among us happy few, these things are loathed by most, so that may take some time. I wonder how bad they age chronologically and how much chance there is to reuse them over the years. But not too keen on finding that out.
Just the other day, I copied some bundle software from a 30 year old OEM 3.5, without errors. Imagine that...

I'll get it on the 15th if UPS tracking can be trusted.

It is a mistake to think you can solve any major problems just with potatoes.

I recently picked up this PCX1. It's been sitting around for a bit, but I finally got around to testing it today. PowerVR Biohazard runs great on the PCX1, and it doesn't suffer from fast CPU issues like the other releases (tested on a 2GHz Willamette Pentium 4). I don't recall if the PCX2 responds the same. I thought Biohazard had fast CPU problems with the PCX2, also, but I'll have to test it again to confirm.

Nice handle: every PC should have one. It's going to be satisfying cleaning that one up and reassembling. I'm looking forward to the before and after.

I have this exact or similar problem on one of my Elsa cards as well. I've only ever tested it on an LCD. Maybe it's a flat panel thing.

I see a Sound Blaster MCV there. I don't know what they go for, but you may have actually gotten a sweet deal. They are rare as gold.

I enjoy them myself, mostly for fun and using the machine to its full potential. I FTP a lot of stuff, especially larger things, though.

If you've got some spare VGA cables to try, maybe one of the ones with a ferrite near each end would help.

Unicorn herding operations are proceeding, but all the totes of hens teeth and barrels of rocking horse poop give them plenty of hiding spots.

I know what you mean but it's probably baked into the signal from the start. Decent VGA wire helps with blurry CRTs and some of the bundled ones of TFTs are surprisingly shitty.
I have the grandmother of all VGA cables on the heap that rivals the average anaconda and also one with BNC on one end. Shall try them out.

I like jumpers.

My understanding is that the ferrite chokes don't so much prevent parasitic signals as suppress them, so it don't matter if it happens in the middle of the cable or you put it in the end, it will still choke it out.

I bought a pack of floppys like that a few years back, they were all dead. I hope you have more luck.

I don't understand why the quality of floppy disk turned to poop towards the 90s. You would think that a company like Sony could be trusted, but theirs were as junk as the rest. I know that they had become a commodity and that maybe this was a way to encourage people to buy more, but the problem was systemic. Could any manufacturer be trusted?

That brand has done okay by me I think, but haven't had many of them. On my "avoid like the plague" list are Memorex translucent colored disks, I think they said "cool disk" on label and package. All of those I had have died, strangely the Memorex solid black or blue ones I've got are still kicking (older?)

edit: I think there was a "race to the bottom" thing going on as bulk price for brand name disks was like $2 per at the beginning of the decade and 25cents or less at the end.

Snarfed a retro GPS, Mio N177 at the thrift, hoping to get this kind of shenanigans going... https://ripitapart.com/tag/miopocket/ ... hoping to have more luck figuring out input devices on this one than that dude had on his magellan.

Floppy disks are a plastic sheet covered with iron oxide. I don't understand what there is to go wrong. It seems like a technology that is easily perfected and not something that is easily to manufacture worse than before.
