I love using this craft/jewelry twister for making #electronic cables. Works way better than a drill chuck because it twists the individual conductors opposite from the whole harness, giving a more-or-less neutral overall twist.

@tubetime being a non native English speaker, I was wondering about the meaning of represerve, the only references I can find online are about humidity indicators.  it would be nice to be able to repair the logic boards. a schematic exists, which is quite helpful.  I received a mysterious aerospace computer from the early 1970s, probably for navigation. It is crammed full of flat-pack integrated circuits surrounding a core memory module. Let's take a look inside... 1/17

A gentleman named Paul Khoury approached me about getting a retro computer he'd acquired up and running. The computer is a Sun SPARCstation UPN (1997), a prototype for a super small desktop computer that preceded the Mac mini by about 6-7 years. Only about 20 were ever made. I was the designer on the project and had poured my soul into it, so I was proud to help him get it running. I dug out the schematics from storage and gave any advice I could remember and he got it powered on in a few days.

 i've published a guide on iFixit that will show you how to disassemble an IBM Thinkpad 700C! https://www.ifixit.com/Guide/IBM+Thinkpad+700C+Disassembly/173038 i like the built-in markup editor they have on iFixit. it makes it very easy to add those little red circles around things. or arrows, or boxes, or other colors... With the introduction of Dolby Surround 7.1 in 2010, Sony were eager to put out a full home theater system. One of their early models, the HT-A7.100, included a revolutionary evolution to the standard stereo jack: the 7.1 surround jack, allowing all 8 channels to be sent over one cable. @mia TRRRRRRRS it's also the sound it makes when you plug/unplug it with the speakers turned on i've gotten nerd sniped into helping fix the IBM 729 tape drive at the Computer History Museum... this basically means i'm buried in IBM schematics that use a totally weird representation of logic gates.  @tubetime Probly waaaay too late to ask, but a video of the restoration progress would rock. Love that stuff.

  @tubetime Is it? Or did you make an extra small hand to use with a regular mouse? (I cannot recall the name of the artist who made this now, someone I found on twitter back in the day.) here's a neat and rare bit of hardware: the Comspec SA-1000 SCSI sidecar for the Amiga 1000! it's got a battery because it is also a real-time clock (the Amiga 1000 doesn't have one). @tubetime I have worked so long on serdes-based interfaces that it is shocking to see parallel ones again.

Intel's 8088 processor powered the IBM PC (1981), ensuring the continuing success of the x86 architecture. The PC team selected the 8088 largely because its system bus was similar to the Intel 8085 processor, which the team had used in the now-forgotten Datamaster computer. 1/8

 @kenshirriff it seems strange to think that it wasn’t until the i486 (1989) that this line of CPUs had on-chip cache. But suppose I am comparing an 8088 CPU with 28k transistors to one with over 1.1m @kenshirriff The 8 bit bus on the Intel 8088 made the IBM PC compatible with the peripherals available for existing 8 bit PCs. DEC even introduced a "Rainbow" with both an 8 bit CPU and an 8088 in the same PC, so it could run both old & new software.  @kenshirriff Thank you for these threads. They are always so fun and interesting to read. some epic haircuts in this Analog Dialogue from 1975. https://www.analog.com/media/en/analog-dialogue/volume-9/number-1/articles/volume9-number1.pdf see page 18

We just open-sourced DOS 4 (and found binaries of Multitasking DOS 4) https://www.hanselman.com/blog/open-sourcing-dos-4

 @shanselman Was MS-DOS 3.x ever released? When can we expect 5.x and 6.x? Can we ever expect 7.x and 8.x? 😅 @shanselman Now we just need Windows XP… anything to help out #ReactOS become more stable! Did any companies build 40 pin DIP Z80s that were functionally identical to the original but had an 8 bit ALU so there were fewer clocks/instuction? here's a neat microcontroller. Dallas DS5000T. programs are stored in battery-backed RAM in an encrypted form.

@tubetime The DS5002 was used for the suicide mcu in Gaelco arcade hardware. https://mamedev.emulab.it/haze/2017/07/17/ds5002fp-dumping/  |
@signalskew so, you can do a legacy server like this then
