you got a picture of the actual chip being sold? Yes, it is in the listing. They uploaded more pictures to add to the first couple. Same "Jaton" pcb... but no VRM. It is a 5 volt cpu i.e. not blue lightning. Though if a chip swap was done... i.e. from a proper blue lightning source de-soldered to …

there's clearly a VRM on the bottom there? if that's actually the one they're selling, seeing as it's not an actual photo, which is what makes this highly suspicious in the first place, how hard can it be to just put up a photo of it? No. On the chip that is being sold, only 4 small SMD resistors …

Been coming and going over the last while though have not posted anything. I wanted to now just to make everyone aware and not to bid on the following as either the seller knows or doesn't... the chip is not real or as advertised. All Blue Lightnings are 3.3 volt chipsets, stepped down by an onboard …

Bit of a random question I know, though I have been ranking from lowest to highest the number of transistors each of CPU's have in and around the 386 era. The regular old DLC's that were done in collaboration with Cyrix had only 600,000, and were with 1Kb cache. The next step up was IBM's blue …

A new addition to the family; - Just found the exact same board in my stash. The manual lists !MER2151.cfg as the matching cfg-file This is great to see...

Personally, I would not attempt it. The Alaris Cougar motherboard is actually a good fit, there are few 386 chipsets out there that will be able to match or even beat Opti both on compatibility and performance. Even if you could remove the CPU and transfer it to another motherboard as a module... …

It is on retronn.de: ftp://retronn.de/dos/games/Duke3D/for386_1.4/ You very likely can't overclock a 386 to the region where Duke3D is well playable. I suppose this is subjective and dependent on a number of factors i.e. the video bus and speed i.e. ISA @ 8Mhz / VLB @ 40Mhz, and whoever is playing …

Recently found out that that Duke 3D was also released on the Megadrive, only in Brazil apparently as the Megadrive had a good continued run out there while everywhere else was becoming obsolete. Though as always, it's great seeing 386's pushed... and in this case running Duke 3D at 5fps!

Nothing goes in between, it would just be a socket extension i.e. a dumb device. The only soldering would be for the sockets male and female. Female socket can be bought online... though the male (pins) would be made with wire i.e. poking lengths through a drilled hole, solder in place and then …

Could be a decent DIY project... there is no additional processing or signal manipulation - just a straight pin-to-pin device, sockets are easy to find online... time really being the only critical factor.

Have you tried doing just a standard DOS diskcopy? Windows 3.11 diskcopy can sometimes copy disks without caring what's on it.
