A bag of retro CPUs! Whaaaaaat?! Of course I bought it.

is this a joke??? just like that, on the store 3.99$?

I got two floppy units, but are a little different from others floppy units: Sony MP-FP53W.

Is that a 3 inch diskette drive from an electric typewriter or is it a normal 3.5" drive? I love the look of that thing but I have my doubts that it's PC compatible. Would be perfect in an XT.
Are both drives the same?

Both are the same. They look the same size, when I compared them with 3,5" drives. I only inserted diskette in it and took it out, just to see if it can take it 😀 It does. However I didn't try them yet in a working computer.

I found a really nice original manual for them here: http://www.bitsavers.org/pdf/sony/floppy/9-97 … tions_Sep85.pdf

Looks like ordinary 34 pin MFM 😀

Ooo, very cool. I may have to pick one up and a matching 5.25 bracket to put in my turbo XT

So I accidently started looking at motherboards again, and accidently saved a few to my watch list, and accidently set a reminder so that I remembered to bid, and accidently placed a bid, and then accidently won it 😒

It's an ASUS P3V133. It comes with a slocket with a 800MHz / 133FSB 1.7volt CPU, 384mb of RAM and a mystery graphics card. I only put a bid of £21 or so, but got it for £18 + £4 or so for delivery.

It turns out it's a TNT2 M64 32mb (seems like an odd combination... perhaps it's just marketing reasons!)

I was regretting this purchase until I found my 1GHz coppermine CPU which should maybe work in the slocket. Same FSB, same volts... I also dug out my big-ass cooler and sound blaster live. I can feel my fastest ever W98 PC coming along!

edit - for once something has gone to plan! The 1000MHz was picked up straight away after setting the jumpers. My cooler will need a smaller fan as it touches the RAM module when only using the right hand slot.

It also has SECC to SECC2 mounting adapters which I didn't know existed and you'll have to pry them out of my cold, dead hands before I let them go.

Good stuff!

I have an almost exactly the same [AMD K5] chip in my collection.

I believe this is the early version which had branch prediction unit disabled. So it performs a bit worse than K5 branded chips. But still should be a little faster than Intel P75.

Interesting... I don't particularly need a 75MHz CPU to be "fast", but is there a util (a la Cyrix) that enables the branch predictor? Any issues doing so? I'm gonna have to add a few results from this beastie to my benchmarking sheet.

I know, I couldn't believe it either. That's why I took the picture. I've seen the odd graphics card or sticks of RAM hanging there, but never a bag of CPUs, and never anything as rare as these ones are these days.

I did swing by again this afternoon for a better 'dig', but I didn't see anything related or anything else interesting. Was hoping for some other choice goods from the same donor.

Saved from the crusher today.

So a looooong line of accidents resulting in good stuff! 😎

Picked up a STB Velocity 4400 on Mercari for $6 last night. (Nvidia Riva TNT 16MB)

Last weekend I managed to get my first SS7 board with K6-2 333 and ATI Rage PCI + as a bonus combined Slot1/S370 board with Celeron 400 and Voodoo Velocity.

Looks like PC Partner MVP3BS7-954. If the motherboard has a 2 Mbit BIOS chip, it could be flashed with the latest BIOS for full AMD K6Plus support.

Thanks for info! I found there are two types of BIOS, but I don't know how to identify which one is on my board. Partnumber is the same for both types...

Try running UNIFLASH its good at identifying bios chips.

Interesting, never used Uniflash, thanks.
BTW, I've found manual. There are factory-set jumpers identifying type of installed BIOS. I should have 2mbit 😀

oooh good to know about uniflash! Thanks

I have just bought 10 of these boards and some other nice things (sellers photo) - of course I dont need that many. They seem to be boards from a PHILIPS PC-XT (5107). CPU, ROM, RAM-sockets and crystals are missing. Seems to be easy to replace and after removing the COM/LPT connectors this may fit in a standard case. Think 8-bit IDE and Floppy is onboard. Hope a standard BIOS will do the job and I get this running 😀

I think I have one of those systems, give me a shout if you need the BIOS.

Thanks, I would be really happy about this!!! I will let you know when I am ready to test...

Received my XT-Boards today. All was packed in a box without any protection (together with some harddisks and a complete 286-PC - photos later). Strange, all are missing the RAMs and several other components. I already picked one which seems to be complete except the RAM, populated with a 8088, CGA and Supersoft-ROM and it seems to be running (except the RAM of course...). I will keep only 1-2 of these boards...
So Cyrix200+, I would be very happy about a ROM-image. Think I need it to use the 8-bit IDE and floppy interface.

got these two 😀

Cherry G80-1000 with (vintage?) MX blue, has a PC/AT switch on the bottom... PC meaning XT in this case according to the info I could find, a bit of confusing labeling there ^^
and a K104 that intrigued me, it has white alps and probably the chunkiest spacebar clack on any keyboard I have owned so far, it has a three position switch on the bottom AT/XT... and... I don't know what the third mode is?
the K104 definitely has seen better days, the backspace key gets stuck, though that can probably be fixed, and the key legends are rubbed off on some keys, but I couldn't pass for the price.

also got a completely different kind of scrap box this time around ^^

a box full of slot brackets 😁
already sorted out some sound card brackets to the right and here's the first happy recipient of a donor bracket. a CT3620 that apparently got a recap from a previous owner?

unfortunately didn't find one that fits my naked CT1600
