Recycle Pile Rescue NEC Ready with a Cyrix M II

Postby detritus olentus » 2018-9-10 @ 18:53

I am not one with the ability to share massive wordy posts so here goes! I stop by a couple of municipal recycle piles on the way to and from classes so once in a while I check whats there. The other day I picked up this unassuming NEC machine with a "Designed for Microsoft Windows 98 Sticker" and didn't think it was anything unusual until I powered it up and saw it had a Cyrix processor in it. I have never had a PC with one so its been kinda neat playing around with it, though I wish I had taken a few pictures when I took it apart to dust it. Does seem to live up to the reputation of producing a lot of heat and the really wacky placement of the PSU appears to be aimed at removing heat from the CPU. Motherboard is also upside-down. Thought it might be something fun to share and I'm always excited when I can save something from the scrap heap. And of course Millennium, because its my schtick.

Not entirely sure why its named "CyrixInstead" when I named it Cyrix in setup. Maybe its an inbuilt insult.

Really like the look at that front plate, very cool.

I have a compaq presario with a cryix MII and I think its actually kind of nice, it just works for late dos/early windows games. I would probably recommend windows 98SE on that build but you do you.

I mostly just do ME as a troll at this point but I also have a legit upgrade disk for it and I like the slightly newer drivers it carries and slightly newer core files. It lets the office compatibility pack partially install with kernelex so I can use XML DOCX files also.

It will be "GenuineIntel" for Intel CPU, and "AuthenticAMD"for AMD respectively. It comes from CPUID.

Nice find! Can't tell much from the screenshots, but apparently you've got an SiS motherboard in there, probably one based on the SiS 5582 or 5592. Out of curiosity, I think you should remove the heatsink and take a look at the CPU itself, it might have been configured incorrectly and you might actually be running it underclocked :D.

Very nice case.

These Cyrixs are good performers for old (non fpu'd) software... albeit I couldn't observe any speed advantage when compared to a Pentium of similar clock. Does the 5582/5592 perform as well as the 5591?

"Coolest" vendor ID was "CentaurHauls"... kinda miss all those different companies and their tacky strings.

Oh, that case is just gorgeous, so much so that I typed "NEC Ready 9851" into eBay search to see if there were more.

Anyone ever get busted liberating equpiment from recycle scrap piles? Where I live, there are cameras and dire warnings everywhere.

Cyrix MII builds get no respect 'round these parts. Its too bad. They aren't all that bad from today's point of view. Just play the games that play well on it. If too slow for you, play that game on one of your other 3 dozen systems.

I love those old NEC Readys, so cool! They're a bit quirky but they're good retroboxes.

I tried building a Cyrix MII-based retro PC for a friend a few days ago and failed. The MII caused so many problems that I replaced it with a Pentium MMX in the end and all problems were gone at once. First, the BIOS failed to enable the L1 cache so I had to use SETMUL. Second, not a single 3dfx Glide game would run. They all triggered a blue screen. Third, mouse cursor was corrupted unless hardware acceleration in Windows was set to the second lowest setting. So sorry to say, but those late Cyrix CPUs are a piece of crap. It had very nice benchmark scores, but who cares it you don't get a stable system.

Hmmm, I never really had any problems with the Cyrix 6x86/MII processors.

But I have only used the MMX versions (6x86MX), which fix a few bugs, and I've always used motherboards that have proper support for them.

i'd love to somehow mod an old NEC tower like this into... sleeper.

I've got a thing for sleepers.

Most likely a BIOS issue or it's just that some boards are unreliable when its sucking power from their rail... which board were you installing it on? I remember, in 2000 or so, also having issues with them but the memories are really faint and back then the Cyrix's,despite being kind of cool, never left any big impression. It was after all the time where more was better. I hoped for slightly better integer performance but it "just"seemed to be up to par with the pentium - at least with the software I tested it with.

A few months ago, all boards I have tested worked flawlessly with a 166(L?) and a MII 333 part. I even overclocked the 333 part from 250 to 290 and cooled it using an AthlonXP heatsink.

The MII 400GP appears to run fine in at MII 433 speeds in my Tyan board with Voodoo3. It runs Win98SE, W2K, and WinXP-SP3
