Rescuing a Prox-1560 Super Socket 7 SBC with an Aladdin V chipset!

We are repairing a small industrial SBC Protech Prox-1560 with a super socket 7 K6-2+ CPU, then we are connecting an AWE64 sound card and trying out some DOS benchmarks and games.

Lovely little machine. Glad there wasn't too much damaged, I think this might have even been within my repair capabilities!

[@1NIGHTMAREGAMER]

tbh looks like classic thrown into a box wih other parts due to how hard ud have to hit that cache chip to shove it like that

[@scrap_computing]

Yeah, I think I was pretty lucky with this one :)

[@AladimBR]

Awesome find! The damage on SMD pins are common, I guess people just toss boards into a box. Recently I got a CT4500 / SB64 which was recognized on Windows but would not play any sounds. I checked it under the microscope and saw damage to the sound processor pins, including 2 missing ones. The seller refunded the money, I kept it as a donor board. Really enjoyed the video.

10:07 - I love this test - if you keep pressing it it'll say "Enjoying yourself?" and then "IT DOESN'T GET ANY BETTER THAN THIS!" hahah

[@scrap_computing]

Thanks for sharing! I will try it next time :D

[@snakezdewiggle6084]

Nice recovery 👍 You can buy pin straighteners.

[@frankgrudge8823]

Love SBC videos always interesting cheers

[@pvc988]

That Realtek controller should work on just about anything. It was one of the most popular PCI Ethernet controllers. Even emulators like QEMU emulate it.

[@scrap_computing]

Yeah these controllers are very common. I (very briefly) looked for a packet driver for DOS, but couldn't find one though.

[@pvc988]

​@@scrap_computing Of course there is driver for DOS. Can't post you how to find it because of course YT has to try to be smarter than it really is and silently deletes my 2 previous comments thinking that filename is an URL. I hate when it happens. YT's antispam filters work the best when you have a legit message to send but bots are happily rampaging here like there is no tomorrow. BTW. It's available on the known vintage computer site that starts with V (maybe this won't get deleted).

[@Vanessaira-Retro]

Shocked that Dallas clock is still going.

[@scrap_computing]

Yeah! I was very surprised too. I can only think of two scenarios: it was either on 24/7 for the last 20+ years, or it had been properly maintained and the Dallas module had been replaced fairly recently.

[@MrJonathanj1981]

Now we are just missing the disk on module. Any chance for a video in the future, where you create such a device perhaps with an sd-card adapter on or similar trick?

[@scrap_computing]

Not sure about an sd-card, but a Pi Pico would probably do the job just fine :)

[@laudennn]

great video, thanks!

[@itstheweirdguy]

I am curious so see this running with the 32 pin 144megabyte disk on chip. That would be cool! Says you can boot from it too

[@scrap_computing]

Good idea! I think I have a couple of these Disk-on-chips, not sure what capacity though.

[@1NIGHTMAREGAMER]

it be cool to see if you could upgrade the cpu or not

[@xsc1000]

It is K6-2+ on 500MHz. There is no much room for upgrade, K6-3 would be only slightly faster but more power hungry. All other Socket 7 CPUs are downgrade.

[@scrap_computing]

The board should support pretty much all socket 7 CPUs.

[@1NIGHTMAREGAMER]

@@xsc1000 still would be fun video to watch

[@mikerogers7071]

👍Good Video

[@detalite]

There are special cases for SBCs. I have one of these and it's ridiculously small. 3 ISA slots and PSU. It looks like that one: "Compact PC chassis FC03".

[@Megatog615]

ridiculously hard to find though. I tried buying one from a manufacturer and they emailed me back and said they actually didn't have any available after I went through the whole purchase process.

[@scrap_computing]

Thanks for sharing, I didn't know they were available. There should be some DIY ones out there too.

[@maniatore2006]

Sorry i can´t hold me back, but kermit the frog, makes Videos... 🤣😂🙈

[@over2seeyer]

how much ?

[@tassdesu]

I think this CPU is too hot to be installed without a fan

[@Powerack]

I don't get it. Super Socket 7 on ISA SBC is pretty useless, if you can't use any PCI or AGP devices. It's pretty much limited just to integrated devices because of the ISA bus.

[@scrap_computing]

Yeah, it's probably best to pair it with a slow Pentium and use it for DOS games.
