To stay period correct these mods seem legit more or less. CGA was the original upgrade from MDA, so possible indeed. For correctness a Hercules card would be more logical as these became available not long after the pc XT (still period correct on a 5150 if you kept it for years). The VGA Wonder 16 …

In 1994 we got a 386DX25 system, bought from my uncle for a reasonably low price. It had a double speed CDROM drive. The kind that would get it's caddy out with motor and reading head and had to open a lid after. It sure was not too common but my uncle was into gimmicks that would cost quite some …

Could you try to remove all non vital components like the network adapter and see if that helps? I guess it can be an IRQ conflict between the network adapter and the ps/2. Does a serial mouse work? That could be a second option... But no fancy light down under then...

This question is regarding my Bakbeest. https://www.vogons.org/viewtopic.php?f=25&t=74636 A few weeks ago I bought an Intel DX4 (SK051, wt cache) CPU to replace the DX2 on my 486. Easy swap, as my board (Intel Ninja) only required to change the voltage from 5 to 3.3v. Now the old DX2 was SL enhanced …

I consider that a lack of space, it's irritating when you want to find a specific part and it takes an hour just to get to the box that contains it. My boards are mostly stored in huge boxes so it's a pain sometimes but I don't have the space to store them separately. That is true. Luckily I have …

Bought this Compaq Prolinea 4/50S for 66€ including shipping. I don't know if I overpaid, but I have wanted a 486 or 386 desktop system with ISA slots for some time. It has integrated Tseng ET4000/W32i graphics, which I suppose is decent for DOS games. Hard drive is missing, hard drive mounting …

Picked up this Aptiva 2196-20A for pocket change. It's a K6-2+ 550, and needs a HDD & optical drive. Also needs a low profile PCI video card. I'll be on the lookout for an FX5500 at a non-silly price. Nice one! This must be one of the last Aptivas before switching to the NetVista models? I guess …

Just one question, and I'm not the only one: Why on earth would you cover up an actual usable port and state in the manual: break me if you want to use an external keyboard??? Just open it up in the first place. Saves a little material (and money over thousands of laptops) and don't let the customer …

If there is a connector, AND you are going to use the external keyboard a lot, then it would be ok to break out the cover I guess. Then again, why would it be there covering a useful connector? If there is no connector but you've got the skills to solder one (and everything that may be needed to get …

I think a 5x86 should be a little faster at 33x4 versus 33x3 for a dx4. Not a full 33% but at least L1 cache and internal cache run faster. L2 and main memory I don't expect to improve much. Also Intel is known to be the best "real" dx4, with AMD being just a little slower, and cyrix/IBM/st/to a bit …

And the DX4 is running! No struggled at all, put it in, changed voltage from 5v too 3,3v and it's all set! Performance went up by about 25-30% so I'm happy :) Cachechk also reported that memory speeds is up. Int cache 10,2ns, was 15ns Ext cache 26,2ns, was 30ns (???) Main mem 34,4ns, was 38,1 So I …

Today I received this little beauty. The mighty Intel DX4, 100MHz pure power. Okey, it's not a WB version, but even so it's a nice addition to replace the DX2 on my Intel Ninja motherboard. Not entirely sure of the heat sink, maybe I'll just fit a better one... This looks like DX-50 material to me. …
