I wonder the same. An old oscillograph really can help checking were the signal comes from and goes to. Tapping some traces with an active speaker box may also work, but it's not as elegant as using an oscillograph. - It doesn't have to be an expensive model. One from the 1960s will work, too. They …

Aw, too bad. 😞 Personally, I think that true RAM disks are principally superior to SSDs. Even had an argument over this with a friend who's a fan of modern tech.

I second that, 4MB upwards is fine for Windows 3.1 on a 286. I used that configuration for years. However, it's possible a power user may need more. However, if we try to run OS/2 v1.3.. I don't honestly know. 🤷‍♂️ For testing purposes, I used 8MB, I think. If we have four slots, maybe we can try …

Well I don't know how, but thought I would try the 4mb modules again since I have been playing with the RAM and the jumpers, and well it now works, I now have 16mb of RAM in the 286, total overkill! That would be awesome for OS/2 v1.3! 😁 There are some Presentation Manager games for v1.2/1.3, even! …

The 5155 has a nice MFM drive, which hums and makes a cool squeak sound if files are accessed.. And it has a real CGA, a glowing amber monitor.. I think it's ideal for diving into (to immerse in) an 80s atmosphere. The hardware was around when the first Terminator film was in the movies. The NEC V20 …

It's perhaps not really helpful, but KVM switches can help to reduce space consumption a bit. That way, two or more PCs can be used by a single keyboard/monitor/mouse. Maybe that helps combining the the PCs into three groups or so. 286/386 group a, 486/Pentium group b, the Pentium II/III group c.. …

I think the same. Both solutions should be fine. Thin Clients do usually have classic ports, because the installed software is aweful. Stuff like Windows CE or some outdated embedded Linux don't have proper drivers. Thus, the hardware has to be very compatible. It has to compensate for the software. …

Um, why don't you just use the defaukt SB16 drivers that do ship with Windows 98SE? The SB16 is hardware-SB compatible, so no VXD Sound Blaster emulation would be needed? 😕 Edit: Never mind. I've just looked up the CT4830..

Because, Windows x86 didn't support 32-Bit UEFI and using the old BIOS/CSM was the only way to boot. I'm curious whether a Compatibility Support Module is inherently custom to each BIOS or each chipset, or if there is a way to write a generic one that could be loaded from disk rather than being an …

15-bit is 5-bit per color without transparency. 16-bit includes transparency. Transparency is used for effects like window shadows. That may be true for textures, but in the framebuffer 15bpp (32k colors) means 5 bits for each of red, green and blue with 1 bit alpha discarded, while 16bpp (64k …
