I can confirm the Adapter in Adapter solution too. I remember CF-cards being more reliable than SD, due to different wear level management, not sure if there might be any performance issue as well. Some actual CF-cards on sale seem to have problems, if used as a boot device, while Kingston ones seem …

Something else I just stumbled across might be helpful with the HDD: http://www.computercraft.com/docs/55noboot.html As for recapping the floppy drive: There is just a sheet metal cover on top and the circuit board just below. You can desolder the caps and replace them without even turning a single …

Seems my slotkets are cheaper than cheap, because they came from different car boot sales or online auctions and none has these plastics. Nevertheless I found pictures of these plastic parts and will start hunting, now after I know what I´m looking for.

If I remember correct the 2.88 MB drive should work, if its the 26 pin ribbon cable type, but the caps are easily to replace. As for the Ethernet card, its like with 16 bit ISA cards in XT slots, some are known to work in the short slots. I don´t have any experience with the ROM Basic, but have a …

What is your experience? I use slotket adapters with S370 Celerons in older LX motherboards designed for SECC cartridge CPUs. But there is no way the slotkets are attached to the motherboard, so they sometimes come loose. Even the retension brackets desined for the SEPP CPU cartridges fail, as they …

Fixed my recently aquired Compaq Profesional Workstation AP400, arriving with a dead power supply (was sold as defective). Fuse was blown and a VDR released its magic smoke. Removed the VDRs remains, replaced the fuse and it is working again. Put in some memory and a HDD and after some hassle with …

In my opinion these old OEM PCs are even more interesting than the generic stuff. Though they sometimes use proprietary parts, memory modules or even worse proprietary software to set up, they are usually a really good choce for retro computing. Quality of the OEM machines build by IBM, hp, Dell and …

If you looked at the refdisk with W95 explorer or later it might be corrupted. For some strange reason the IBM refdisks dont like the windows explorer. The IBM floppy drives are suspect as well. They tend to give read errors due to bad caps. repair tutorial can be found in another thread. Maybe …

If it doesn´t show a picture in DOS but works in windows there may be some BIOS corruption. You could try a reflash. As mentioned before it should work with older systems. It was the first PCI video card I ever owned, switching from a ISA based ET4000 on my old P133. Board was a Gigabyte GA586VX if …
