Bought on a flea market yesterday.

Pcchips m921 in mint conditition + intel overdrive (probably a dx4 100)
Sound Blaster 16 ct2290 looking as new
Boring Sound blaster PCI and Radeon 9000 AGP
and some unrelated retro pc parts.

The Pc Chips M921 board seems to be a good one.

Got a Belinea CRT from a friend of mine... after adjusting some of the settings I was pretty happy with the picture. Although Belinea was a poor man's company(when it came to monitors it seems) the camera is not really able to do the picture justice. Now I have at least one bigger CRT that nicely goes together with the 486/586 boards.

Also, I got a very good deal on a very strange looking mystery computer:

Couldn't resist it.. Any bets on what we have inside?

Picked this up for $15 tonight. Opened it up dreading to find a Pentium MMX system and hoping for a Super Socket 7. I got neither.

It's a Celeron system with Zida LX98-CT board, three sticks of RAM, some unidientified Celeron PPGA CPU, an ISA modem, a PCI USB 2.0 card, a Genius ES1868 ISA sound card and a Voodoo 3 3000 AGP without a TV-Out (I thought 3000s had TV-out, strange..)

All in all, not a bad haul.

The case has definite markings that label it as a Pentium 133 out of the factory, this PC has been upgraded extensively since then. I will revert it to a P5 or P54C DOS PC, now that my attempts at building a 486 appear to have gloriously failed..

@appiah4
What form factor is that chassis? Look small and inverted (5.25 bays on bottom).

Inverted baby at. Very strange case indeed.

My last adquisition.
An external USB floppy drive.

The quick/temporal solution to transfer files from my "current" PC to 486.

Works even in my smartphone trough OTG cable. 😁

In my opinion CRT monitor is better than TFT for vintage computers.
Recently I installed a 17'' CRT SONY Trinitron in my 486 and the result is very nice.

Paid 20 for this combo. fake cache

- infamous M919 with fake cache
- Infamous M915i with fake writeback cache
- Unknown SIS board with soldered cache, probably fake too. If anyone knows the model please let me know.

Hi,
The last mainboard is the same that my 486!!!
How can I verify if it has a fake cache? From the BIOS or on startup messages?

SeconDRAY HDD 🤣

As sketchy as that last board is (spelling is hard! 🤣 ), that cache looks socketed and the jumper headers appear to be present. Was there fake cache that was socketed?

there is a dos tool called cachechk that checks if the cache is real or not
but if the chip says writeback its mostly fake

Also I can just barely make out "WRITE BACK" on those cache chips. Definitely fake.

Ahh, yeah that sounds fake. I could hardly see any writing on those chips.

Hey, it's pretty good! How large is the monitor?

It is a 17 incher - viewable area measured approx. 15". I once found a 24" Sony on a local site "butt" the owner wanted 400$+.

The original picture was meh, but after re-adjustment(contrast 85, brightness 40, blue component raised) it turned out to be pretty lively, even adding a nice "bite" to some colors.

I primarily use an old EIZO flatscreen for reading surfing/editing and while its color reproduction is superior to the Belinea's, the picture quality as a whole appears better on the, rather cheap, CRT.
From my perspective the crt's strength lies in the luminous quality of the picture. It adds depth and life while the higher "fidelity", more accurate one drawn by the flatscreen appears like molten plastic... it's like somebody is painting the screen with high accuracy crayons.

Try posting on your local facebook sell groups wanting to buy old CRT monitors.

There will be tons of people who bought these monitors but were too lazy/old/frail to get them out of the house once they retired them so they just sat them in a closet or in a corner or there shed/garage. Plunty of people will offer to give them to you just to get rid of them. I got two of my Macintoshs this way (not for free, $25 each) including a somewhat rare G3 233 iMac Bondi and a late production run eMac.

Won two 4890's on ebay, but the seller somehow forgot to put in the shipping info and now I'm wanting on a invoice. Hopefully these two will be good.

EDIT:
Got the, for 53$ usd after shipping from Candida. Not a bad deal for two very nice 4890's with 2 CF bridges and the RGB cable.

I also got some ddr3 ram, 2133 9-11-9-26 timings and a new (no box) P5E64 WS EVOLUTION.

This thing.... To use with old systems of various kinds. Will see how it goes and performs with Amiga600 and Playstation2.

Got a some sound cards. 5 Compaq branded ES 1869F with onboard wavetable and a new Aopen card with Yamaha chip.
