I have the Compaq Presario 9232 as well. I replaced the motherboard battery with a direct replacement. It is a Panasonic BR-1632A/GAN. They are $2 at Digikey. https://www.digikey.com/en/products/detail/panasonic-bsg/BR-1632A-GAN/447502 I bought the computer new in 1996, and the original motherboard …

I stick with Intel for wired LAN, and Intel or Qualcomm/Athreros for wireless. That said, I did experience my first Intel NIC partial failure in my pfSense firewall. All four ports would just drop about once a month, requiring a reboot. Jetway JNF9HG-2930 with 4 x Intel i211AT. However, it had …

If some was to go the cheap route, I'd suggest the Pro Mini or Digispark + whatever LED display, then just solder it to a perfboard. It would probably be around $5-6. My project is $10.42 to build, ordering from Mouser with a quantity of 1. Filename mouser.PNG File size 1.46 KiB Views 99 views

It's essentially the same thing as using an ATTiny85 as I have made. Just a larger footprint with extra I/O. As far as cost to produce them in sets of 10, it would cost more to go the Arduino Nano + LED display + i/o board route. As for a 1-off build, it may be cheaper if everything was sourced from …

It's not sanded at all, nor painted. The case design files are posted here on Vogons.

I simply using an arduino nano or just an ATMega328 plus one of those 0.36" 7-Segment Display TM1637. Fits perfectly and way cheaper. Plus you can program it to your own taste. Mine is scrolling and glowing up at start for example. Feel free to post up the pics, schematic for how you have it hooked …

I made it 4 layer for signal shielding. Don't think it is necessary, but it also gives a clean top and bottom with no visible traces. The price difference for a board this small is negligible.

People should just follow the silkscreen. If in doubt, look at the schematic to confirm.

Don't know why it doesn't make sense. If you install a capacitor backwards, it will smoke. They are on a negative voltage rail. Ground is more positive than a negative value. 😉

Per the datasheet, it is a direct drive 0.5" common anode display. Those are really common and newly manufactured replacements can be found at Mouser, Digikey, eBay, Aliexpress, Amazon, etc. The transistors can also be found at the same places. All those components can be tested for failure, just …

Yea I looked identical, just all the NSM stuff covered up. As far as Winamp support, I'm sure a plugin could be coded for it.

How do I find them on ebay? You don't. They all gone. There were only two units. We will need to let someone else do the testing, preferably on a slow system in DOS, Win3.1, W95, and I hope NT 3.51 and NT 4.0. It'd be great if someone can figure out how to get it working in a compatible Amiga as …
