Re: A couple of retros I'm working on.

I also wouldnt use non rechargeable Lithiums in this case as RTC replacement becasue the T52xx and T32xx series have oh so slight backcurrents when the computer is turned on. This will damage or at least severely damper the lifetime of your button cell over time. Instead I would use a genuine 3.7 …

I would check/get rid of that Conner 100MB drive as soon as possible and replace it with either another HDD or CF/SF alternatives. The 20-120MB range are prone to cease working and even worse, can leak oil all over your motherboard. I'm not kidding. One was doing exactly that when I tested it …

Well, I replaced the caps because they looked bulged. I never replace caps "just because" because it makes no sense. It's just stressing the hardware unnecessary. Anyway, yes, I tested them using an capacitance meter (which tests ESR as well). Even they looked bulged, they were all still fine. This …

I was more thinking about vintage laptops when writing this, which seems to me the main target audience, not being able to do anything else if no soundcard is present. And with PCMCIA soundcards being pretty much not an option anymore for ppl who do not have one, as well as the fact that many 386s …

Some news from dkgrizzly : He patched adlib tracker to support OPL2LPT and 2xOPL2LPT ! : https://github.com/dkgrizzly/at2lpt/releases/tag/at2lpt-beta-001 Wait, I thought Adlib Tracker II was all about OPL3 now and that OPL2 support was considered deprecated years ago! :shocked: So does that mean it …

I have the Virge DX in mobile form in two of my laptops (MX then?) and although 3D is pretty much useless (exception being the 12 Virge accelerated games like Descent), the 2D is impaccable. Also no problems in regards to 640x480 on an external display although that, too might be accredited to them …

I solved it with an 80mbs hd. the problem is that in the bios-setup has only 55 types and can not be entered manually, as in a generic bios.

I recapped another Socket A motherboard last night. An ECS K7S5A. It really satisfies me to take a dead board, slap some new Nichicons into it, and watch it live again. Hopefully it sells on ebay for someone looking to make a XP gamer. https://imgur.com/gallery/W68EO Nichicons sure do look pretty. …

without a diskette, it does not read from C and it remains hung There is no bios, only system configuration on NVRAM part of the RTC.

Get a new (old) computer. say to yourself it's really worth it. Good price. Will work without a hassle. One week later..: Still fiddling around with what should have been a one-afternoon deal. Frustration ensues.

Either the battery voltage is too low to save the settings (I dont think so, 2.72 Volts should be enough), OR the compaq bios is not accepting either the drive OR the values you put in the bios. What settings are not being saved? All the settings (like you changing COM settings for example), or ONLY …

The compaq BIOS with these machines resides on their own little partition that is created at the beginning of the drive structure. If you have formatted the drive or switched it, you probably do not have this partition anymore, which results in you being unable to load the BIOS Setup Program. You …

The only 9-pin game pad of my knowledge is the Gravis Stinger Serial Laptop Game Pad. This one is Windows 95&98 only. You could make use of this game pad, however there is no genuine DOS support, so you would have to implement the Windows Joystick support. This has been done with various Windows 95- …
