This thing arrived... payed a bit more than usual (~100USD) but beside some minor scratches on the case this thing is in like new condition (even battery doesn't have any leaks).

Re: I killed my Asus P3B-F. Can it be saved?

If it's a matter of 'zapped chipset' then the easy solution is to replace the chipset. Not as hard or expensive as you may think, and there's plenty of cheap/broken BX motherboards you can use as donors.

Exactly. These connectors never were standardized. I've seen some that charge connected battery pack, some that don't. Some were just hardwired to 'internal' battery circuit, some had separate circuit that had to be switched by hand.

Never connect triple AA battery pack into anything else than 'external battery' connector. Ideally use reachargable batteries if you are not sure if the external connector is not charging batteries when the power is on (you can also verify it with multimeter). I've seen some motherboards that had …

I'm not sure if you can really measure the CPU's speed unless you make some kind of expansion card that would read the FSB AND the CPUID (because I don't think you can simply measure the DX2 or DX4's speed) Well… CPUs for a long time had some sort of internal frequency dividers/multipliers so it's …

AFAIK Arduino can be made into frequency counter good even up to 100Mhz (here is the code for one working with frequencies upto 64MHz: https://github.com/abdallah-ali-abdallah/Arduino-Frequency-Counter-with-LCD ). So instead of putting an effort into doing it the classic way - I would do universal …
Re: Replacement AT Power connectors
Posted on 2019-05-10, 13:38
IF you really want to convert them.. maybe take stuff from a couple of dead AT power supplies? As for me, I don't trust old AT power supplies one bit. It is much easier and cheap to just use newer ATX power supplies with an ATX to AT adapter... and you can get them with -5v added if need be. I …
Re: Is there a DOS-compatible handheld gamepad with analog stick?
Posted on 2019-05-09, 01:17
I can't speak for the other controllers but they look fairly complicated to me, so likely require software to use most of their funcitons. The PC PowerPad Pro may work as a standard gameport device with the switches set a specific way, but the most it can possibly utilize without drivers in DOS …

Re: Reworking a DS12B887 Clock Chip

So the clock battery on my Pentium 133 machine finally died on me the other day. Strangely, this has left the computer completely unusable! When I boot, it forces me into the CMOS to restore settings, but upon leaving the CMOS setup, the computer immediately reboots and forgets everything I just …

Re: 80286 Mainboard Bios needed
Posted on 2019-05-07, 21:56
You are right.In case its a very old BIOS, maybe you have to enter the amount of memory manually? Yeah, I've seen it in some 286 Award BIOSes - you would have to enter it manually and it would verify it during POST memory test. If I entered lower amount - it wouldn't bother to test any further and …

Are you sure about VX supporting only 1 DIMM slot? Perhaps some VX mobos only had 1 SDRAM slot, but some had two... Take for example my Shuttle HOT-555A, it has two DIMM slots, but is capped to 32mb, per DIMM. Iirc most didn't have any DIMM slots and if they did, they had just 1. I actually thought …
