[...] Yeah, I imagine it'd vary from board to board. The board does work, just never got far with a flat RTC battery, although I sometimes could coax it into booting into the OS. I have installed a socket in place of the module which cost me 65 cents AUD. I also bought a (probably new old stock) …

I just cleaned up a couple of mechanical keyboards I've had laying around since spring. One is a Vendex XT-compatible in beautiful condition (with, I believe Hi-Tek switches) and the other is a Focus FK-2001 which seems to have some kind of white Alps switches. Also had to fix a broken case tab on …

Agreed. Whether a board with Dallas RTC will boot or not with an RTC with dead battery varies (usually they do, but enough well-known exceptions), but with no RTC module at all, they generally will not. If you're worried about going to the cost and trouble of a new RTC if you're not sure that the …

I don't think most Dallas-equipped boards would be able to POST without one installed. It does more than just keep time, as it has NVRAM to store BIOS configuration properties. The board will likely try to access these at POST, then fail the POST as it never is able to access it. It's also why a …

The only motherboard I have with a Dallas chip is also a Socket 5 with similar SIS chipset to yours, which also came with a Pentium 75. With a dead Dallas, it would POST but not boot anything. When I removed the dead Dallas chip (which was luckily socketed) and turned it on, it wouldn't POST but …

I can't say for your specific board but it's not uncommon for boards not to POST without the RTC module. Some won't even POST with a drained battery in the module. That's encouraging, I was able to get the computer to POST with a drained battery in the module, but it'd forget all of the BIOS …

I put a socket on a mainboard that had a soldered in Dallas RTC chip. Oh and I used Windows XP on a CRT monitor from 1997.

I have an Olivetti Pentium 75 machine that I acquired a while back, the computer isn't broken, I was able to get it to POST and boot, but it had a Dallas DS12887a RTC chip on there which had died, unfortunately it was soldered in, but I did manage to remove it and now I have the mainboard with a …

I use a 14" AcerView 34e CRT monitor. Works well enough, has good colours and all. Also have a 15" LG StudioWorks 57i CRT monitor but that's broken and I don't have the parts to repair it. The high voltage regulation on the Acer is a little bit iffy (image shrinks or expands slightly based on …

G'day all, I have a question regarding CRT monitors and horizontal scan frequencies. A friend owns a Topcon branded 15" CRT monitor from 1997 (Max H-Freq ~69KHz, max resolution 1280x1024 @60Hz), and he accidentally ended up feeding it a signal that somehow had a H-frequency of ~90KHz (resolution and …

G'day all, not sure if this is the right place to post this (please let me know if it's not). I have a 14" AcerView 34e CRT monitor from 1997 which I use with my retro computers. It's has good colours and a good image and all, but it does have that problem with the image shrinking and expanding …

the trick is to use a lower shutter speed on your camera, otherwise you will see noticeable lines on the photograph. For starter, try a shutter speed of 1/30s if your monitor has a 60hz refresh rate. Interesting. Always knew it was to do with the refresh rate and shutter speed not lining up and all …

AcerView 34e CRT monitor from 1997. 14" (13.1" viewable). Quite a nice monitor to use, works well for classic DOS gaming. The heater is actually visible from outside when the monitor is switched on. Only downfall is that it has a bit of a problem with "CRT bloom". Wish that I could get 1024x768 @ …
