Sometimes. Those Chinese T15 kits/irons can be fantastic. I have one that's way better than my FX-888.

The beauty of a C3 isn't top end performance. Might I suggest starting to subject it to some SETMUL magic?

Do a diode check on the bridge rectifier and impedance checks on the X caps (yellow bricks in the picture above) and filter choke. I suspect something has failed open on the primary.

The caps are most likely for noise suppression or buck converter use. Poly caps, 6.3v and 1000uf with similar case sizes will probably work fine (not guaranteed, though). Still, a generic GF2MX might not be worth it. I'd give you one of mine if you were close -- I've got a few extra.

That or a KVM switch. Both AT and PS/2 will work (with adapters for PS/2). How does a KVM-switch help with MIDI? KVM switches are also very useful with multi-PC setups, but they just do keyboard, video & mouse (although some have serial and/or audio too, but none that I'm aware of MIDI) AT keyboard …

Any opinions on these? They all look pretty bad TBH. I'm dealing with some old AT desktops/minitowers out of my storage room; probably going to keep two and get rid of two. If there's any specific ones I should save, let me know ASAP. These all seem to work, but they've endured several summer/ …

Here are the caps. They are through hole. I have replaced caps on a motherboard before, so I have a very basic idea of how to do it. (Not saying I am good at it). My main question is whether I can replace cylindrical polymer caps with radial aluminum electrolytic caps, in general. Thanks. What's …

I've got a soldering manual from NASA of all organizations, but the biggest hurdle in soldering is MONEY. If you don't have good materials and equipment, you won't get excellent results with anything but basic soldering jobs. More expensive equipment (hmm, Metcal) can make it easier to do a great …

Alternative: do both. You can get MIDI patchbays that let you connect different inputs to different outputs. The big ones tend to get expensive, but you can find 2 in, 2 out versions for very reasonable prices. Then you could connect the 486 and SS7 systems to the inputs of the patchbay and the …

I don't think it's possible. Maybe with a terrible ISA card, downclocking, and slow memory timings? But even a fast 486/66 can get down to 286 speeds with combinations of Turbo switch, cache disabling and slower memory timings--without resorting to downclocking the cpu frequency. I think Pentium …
Re: Turtle Beach ISA sound cards - some questions please
Posted on 2018-11-23, 17:37
I've been looking through my vintage PC components, and found two interesting looking Turtle Beach ISA sound cards. One is a Tropez Classic (I think), the other a Maui. Some questions please: 1) Do they work for DOS games? More specifically - 1a) can a DOS game access the wavetable ROM? 1b) can a …

Re: Barrel battery repair ?

The charging profile of a Li-Ion battery is quite different than the original barrel pack. NiCd (what was probably originally installed) and NiMH batteries are generally not so sensitive and have fairly simple charging circuits. They also have similar voltages per cell, so you can generally use …

Ghost is pretty good. The only weakness is the anemic networking support (depends on what's built into the DOS boot disk).
