What have you done with an H/PC today?

torch,

Haha, yeah the sound coming out of the HP360LX speaker isn’t great today, but imagine back in 1997! FM in my HP360LX.

Couple of days ago, I open up my HP 360LX, yeah some of you might cry. Why, because it seems like it’s snappier than my other HP 360LX. I got several and all of them has unbroken seals inside the battery compartment. And I wanted to paint the motherboard with
conformal coating 419D

I remember this website. And about the third picture on this website the motherboard looks normal, for the HP 360LX.

See my attached pic for the difference. And I don’t get why there are extra cables and soldered chips beside the processor.




Now I’m afraid this thing is being tracked? Or maybe a speed boost for the 60Mhz SH3?

Any information about these connections?

re: motherboard mystery

Ok, now I feel ok that it’s not bugged or anything. Thank you @torch.

I have missed that thread last year.

I honestly don’t know much about that stuff. I just remembered that thread and wasn’t sure if it was similar to what you noticed too

I personally use my PDA to take notes, for a novel I'm working on.

I've used a printer with screen, to make some notes too.

But now I have gathered every bit of what I've written on them, I don't use them right now.

Except for writing things to buy down at the grocery store.

Lol, I'm kidding, it's not the only way I'm using them. There are also plenty of games running on this.

Best regards,

Matthias.

Today I rebuilt the battery for my new sig3. Finally I can use it without being tethered to the wall. Also, good lord these cells were in bad shape! Thankfully the controller board was fine.

In case others want to try this with their sig3: Sig3 battery replacement
Note: not my video

Wow! I have never seen a Li-ion battery go like that!

I know right? The other one was even worse. I originally was thinking maybe they hadn't been charged at all for the last twenty years or so (the device itself looks nearly brand new) but then, the rechargeable backup battery popped back to life after being plugged in for a day or so....

WARNING: If you do this please carefully check the polarity and voltage of the adapter and connector at every step to avoid damaging your precious sig 3!!

Today I made an adapter for my sig 3 so I can plug it into USB and other power sources using a standard 5.5x2.1mm barrel jack.

Thanks to stingraze for the link to an awesome tutorial on how to use the connector from a Sony pega-ac10 power brick to make a sigmarion 3 power adapter. You can read the tutorial here:
Sig3 power adapter tutorial (Japanese)

Steps:
1. Harvest the connector from the Sony adapter and discard the rest
2. Shave down the raised portion of the connector (on the opposite side from the arrow) to match the sig3
3. Ensure fit
4. Check polarity diagrams on the adapters and check with multimeter
5. Cut barrel jack from sacrificial barrel adapter
6. Check polarity with your intended adapter. Most of the modern ones have negative on the outer sleeve
7. Wire barrel jack to sig 3 connector
8. Double check voltages and polarity
9. Plug in and enjoy!

And here are the links to some materials I used:

Barrel jack:


9v USB power adapter:


And an example of the Sony adapter on eBay:

Here's a comparison of the shaved sony connector and the original sig 3 one.

Note that the arrow on the Sony connector is on the "bottom" as compared to the sig3 connector. So after you modify it, the arrow will be on the bottom when it plugs in to the sig3.

Nothing much. But SUPER for the 200lx at mizj.com has been migrated away from GoDaddy to Strato (much better service IMHO), and will also support https now. A bit safer, although it is the most plain html code possible, no passwords, no cookies, no javascript, no nothing. Downloads from any browser still possible. Just do NOT leech (eg wget) the site, just download it whole as a 7-zip file as indicated on top of the site.

Playing NetHack offline with my Sigmarion 1.

I went to Akihabara today, and it was lots of fun.
Surprised to see so many foreigners, probably because of the weak JPY.

Hi, I am new here. Back in 2005-7 I programmed in NETCF the WinCE terminals (Symbol) and wrote some tiny drivers layer and executed terminal NETCF apps also on desktop for development... thats gone :-). Now today, I have here one quite fast terminal MC2100 and also two oldtimers SH3 Compaq C140 (4M) and Phenom H120 (8M) where I want to test my C written tiny app, I just checked new 512 CF card with pcmcia adapter on them, in Phenom it worked as-was, in Compaq, I reformatted it inside... okay. ARM Jornada 720 is on the way here ... I want use these as test devices for my tiny C work (already tested on some embedded boards, home computers and CP/M) ... BUT I have one question - how to deal with these devices connected to Win10/11 computer today? I still somehow possible to use ActiveSync? Or must I install somewhere older system? How to install on these devices thing like xt-ce ("pocket dos"?)? Is it available somewhere? Is some CP/M emulator for this? (I mean real, with z80 emu and bdos/bios) ... How to setup some software? I have something stored in my old archives for sure (was heavy user of WINCE smartphones, MPX200 and QTEK)... where to find software today, are some large archives (like for CP/M or so)? ... BUT crucial thing is how to CONNECT to these today? I have serial cables at least (max 115200?). Will even desktop development tools (Visual C) be able to connect to target over serial line (that activesync? - I used later commandline tools over this link, not the entire packga for "syncing"...) Cant remember all, probably...

Have a nice day!

actually, found "support & tutorials" ... okay ))
