Did anyone build a search engine including only websites without any JavaScript ? (Not a proxy that strips JS — rendering the site unuseable — sites that don’t contain any as is).

That would be wonderful for .

I should add than but I once bought https://humanlinks.org domain in order to do something similar. Original idea was actually to collect links from participating instances (using admin moderation to filter good content in public posts themselves and search only that).

It just hit me now that should tag pages with zero JavaScript and allow search in there exclusively.

@santiago killer idea. You may know about https://1mb.club and https://250kb.club which are DIRECTORIES of tiny sites but don't contain a search engine for them as far as I know. 10kbclub appears to be gone but glad these two are still going. I bet there's more like these too.

Got a Logitech ScanMan 32 handheld grayscale scanner for the Mac. I think it’s like the PC version but with an additional box to convert to SCSI.

I’ve never owned a handheld scanner before so this is going to be fun/awful. I want to try it with the #AppleLisaClone

sumilumi,

@paulrickards DC of either polarity should work but it comes with some caveats. The circuit may or may not be sensitive to the effects of using rectification diodes which have quite a voltage drop and can be a source of electrical noise. This drop can depending on the circuit also shift 0V earth to well above or below which introduces all manner of ground loop problems if the device connects to anything external that is also grounded.

jrychter,

@paulrickards I owned a ScanMan 256 (still have it somewhere, I think). I don't think I ever got a straight scan out of that thing. 🙂 It requires a robot-level steady hand.

Oof, the SSD speeds are slower on the PowerCenter compared to my G4 MDD or even the G3 B&W. Might be because I'm running a Rage 128 on the same PCI Bus or maybe it's because of the slower processor and bus speeds.

Faster than any SCSI emulator though.

@chikorita157 I like how SSDs are quiet, that makes it worth it for me :)

If the accelerator card has memory on it, it probably can ran the memory at a higher speed which equals speed etc. No idea if that’s the case :)

chikorita157,
@chikorita157@sakurajima.moe avatar

@yon The accelerator cards usually have backside L2 cache, which speeds things up drastically. I am using a 604 without a cache since it’s missing and it doesn’t perform well in certain instances.

Not only that, the 68K emulator kind of depends on that cache, so without it, performance is impacted.

My weekend reading is the story of Don Estridge, the manager who led the development of the IBM 5150 computer better known as the PC:

👆 I read the story of Don Estridge, the manager who led the development of the IBM PC. His decency is moving and long gone in the tech industry.

That story is worth reading not just for how Estridge pushed the boundaries of the computer industry, but also how he pushed the boundaries of humanity in business. Which these days is an oxymoron.

TIL you need Winzip 9 to unarchive zips bigger than 4GB. I guess Windows XP is these days.

It’ll probably take a few hours for this old Sony Vaio laptop to unzip all these WHD & modules.

This 1.5Ghz Pentium M manages to run WinUAE decently if you find the right settings with no fancy scaling but it’s close to the limit.

A laptop with a 800x600 screen would be ideal to fit #Amiga native resolution but the ones with these screens are probably not fast enough. Not sure it won’t drop frames running Demos but I mostly intend to use it as a small 1024x768 Workbench. Looks nice at 12”.

Got this Unidisk drive a few weeks ago. Unfortunately I couldn't insert a floppy disk, so I opened it, did a full maintenance and changed the infamous shitty gear that broke as soon as I touched it.

Opened Unidisk floppy drive.
Opened ejection gears of the Unidisk floppy drive.
A broken gear.

fenarinarsa,
@fenarinarsa@shelter.moe avatar

Checking the motorized ejection mechanism. The Unidisk is based around a standard Mac floppy drive from 1984.

And yeah there were third party desktop apps for the 8-bits Apple II, based on ProDOS. So full support for block devices, which means HDD, ramdisk and this Unidisk drive. To be honest it's really slow but it works very well and as expected!

The Unidisk is detected in slot 5,1 and format went smoothly.
It's a 800k drive = 1600 blocks of 512 bytes.

Automatic ejection is also handled by MouseDesk but there's no automatic insertion detect like on Mac.

When was the last time you typed ATDT? #Retrocomputing #HayesStandard

cs,
@cs@mastodon.sdf.org avatar

Thanks everyone for participating. I know many people used ATDP. See the replies.

I cannot remember when I last had to type it. Even while I was still on dial-up, software like #Procomm did the dialing, but early on had to type it a lot.

@cs I loved procomm. Best of all of them

Finally got my performa 6200 to run. Reason was a faulty Cache/ROM-DIMM that I replaced with another faulty DIMM. The third one is working 😀

hankg,

It’s not every day I get to play with a Xerox Alto thanks to the people at The Computer Museum in Maryland! I suck at Missile Command BTW. Great exhibit space and worth a visit!

Some old but fascinating notes on the history of window systems by David Rosenthal, who worked on X-Windows and NeWS.

The post starts by commenting some remarks by Alan Kay on browser architecture and goes from there, discussing the work of other pioneers and their own comments. It covers display PostScript and other interesting system design ideas.

Can anyone confirm the PSU specs for the Radius PowerView 0346 SCSI video adapter for Mac?

It lists 5V 1.5A on the back but no polarity. I think it’s center positive but would like confirmation. Thx!

paulrickards,
@paulrickards@mastodon.social avatar

So I took the Radius PowerView apart and the PSU polarity is center positive. Here’s the inside along with the ROM.
