Ingenious...

Just been given one of these, with the exact same fault. I'm not up for changing the output chips either! Must be a common problem.

Did you manage to make an image of the hard drive in the end?

Cool machine

I bought an IDE to CF Adapter from AliExpress recently which arrived a few days ago & it turned out that some of the IDE Pins & CF Pins were bent so made sure they were all straight before I even consider using it, Just need some software now to stick on a CF Card to make use of it!

Hi, glad to find your video. I have problem with massive corrosion at elko and battery area. Could you tell me where the connection of elko leads to? Both end have connection actually 😢 I tried to find pcb description but didn’t. 🙏

Did anyone take the ribbon to stop anyone booting it up.

Without a battery you lose the CMOS and the settings so that is that.

My greetings from Indonesia. I also have the same item, the problem is that the sound is hoarse and noisy at low volume or a quarter turn, and the transitionor is hot after using it for more than 10 minutes. Can you provide a solution to this problem? Thank You

Yes there right you found it finally

Mate don’t break it there’s another torque screw the other way 😃😃

Fair enough but why make a meal out of it mate. It’sa 3 mins video going on 33mins? Makes it really boring

You OK Jay?

Hi, sorry to bother you but do you have any idea about faults on humax Freesat box ? It won’t power on but it makes a kind of intermittent sound kind of like how a hdd sounds with the sound going up an down like a buzzing clicking kind of sound! Would you say it’s processor or faulty capacitor ?

Are you dead Jay?

I would buy one, seems very rare these days.

Brilliant thankyou👍

Great video your demonstration is easy to follow I’m in my 80s so I won’t be messing with the battery It needs a nerd like you 😂 but it helps me understand what night be wrong with my sweeper I have a new dock and battery wonder if the button is faulty thanks 😊

I have one, complete with the VHF antenna adapter for Air / Maritime band. Now, it has very low volume, so I have to repair it. The only weak point in performance of this radio is in VHF Air-Maritime band, where you listen substantially image frequencies of FM band.

You don't happen to repair cdi 220 by any chance do you Jay?

Hi, I have the same computer and when I connect the battery charger the LED continues to flash red and green endlessly. Do you know what the problem could be? Thanks

great video my friend. Thank you. Tony

morning. I did enjoy this video my friend. Thank you tony Leicestershire.

Were so I get the screen to buy

Just fixed my mower while following your video , thanks very much 👍

with the fishy smell of the capacitors and the vinegar its like a chip shop lol

Spotted it was only picking up one of your ram sticks when you went in the BIOS! A lot of those e-waste laptops are perfectly fine, just the ugly result of early obsolesence of otherwise perfectly fine machines, more bargains for us though.

have the same speaker the same issue but condition is tragedy im not sure if repair is expensive both TDA8922CJ cost max £10 , on my also i dont know whats happen but power supply at the bottom was almost black crazy never seen something like this but is working i removed both tda bluetooth working also input capacitors on TDA was cooked :/

Please USB floppy drive full repair video create and upload video

Thank you for this series of videos, they brought back a lot of good memories which are obviously mixed in with the nightmares of tape loading problems. I owned a ZX81 from 1982 to 1983 and it was the computer I taught myself programming on. I'm still programming 40+ years later and still enjoy it now. I'm recoding some 3D bits and bobs I wrote a long while back, OpenGL 3.1 with C++. It's been a great watch seeing you revive and reanimate this poor ZX81, and what a great way to end the series - 3D Monster Maze! I swapped 3D Defender for 3D Monster Maze with my cousin who found it too scary :D Mazogs is also one of my favourites, the forerunner to Maziacs on the Spectrum.

Did you ever get around making a video on how to build the external drive?

hi are you not well have not seen you 4 a while hope all is well

Good job! When I was a child have VEGA-402 (older model) Now l remade my radio to FM, because nothing on AM in Russia.

Thanks!

Perfect! Thanks I'm attempting to win one of these on eBay, if I win, it will go straight to my work bench.

I was a BT Merlin engineer back in the late 80's. We installed/maintained rebadged Zenith machines. This model was called the Merlin M5200. The XT model was called the M5150. Our first laptops were twin floppy, monochrome Zeniths as well. Thanks for the video, it brings back a lot of memories.

Congratulations on 2k subs! That radio's got potential, should sound good with the 8" speaker. It's just all the usual suspects innit? At least anything hard to find/expensive seems to have survived unscathed.

Did you finally replace your phone since it's about a year since this video was made?

Great!

Hi! What was the screwdriver type/size that fitted to remove the battery compartiment? Best regards!

Useful video, thanks! I this exact drive as well, connected to a Greaseweazle V4. There are a few manuals online for closely related drives that should help, just search for MF504. If you want to remove the latch lever and bezel, there's a cap that's snapped into the lever which hides a small screw, once the lever is off you can undo the two bezel screws and two latches to remove it. From there it's possible to remove the top half of the drive and get access to clean the entire diskette slot.

Hi friend, sorry for the ask but, how you do to runs the ImageDisc?? I will prepare a HD whit MSDos, also i have download the sofware from the Daves Old Computers web page, but i dont know how to runs it. I thank you in advance for you help . Grettings .

That first sound was just it's heart beating :)

Use av may be that will work.

This is an RF filter. They are in most PET and CBM computers. It can be like that, or it can be wired directly into the computer power receptacle. If you see a covered back on the plug socket, it's likely the one with a built-in RF filter. Replace the receptacle in that case. And if a separate RF filter, remove it entirely - it's not needed with a powerbar with an RF filter.

RF Filter - remove it. It is usually the cause of issues - fails with a puff of smoke and stink. Then dead machine. Power today is cleaner and besides, most powerbars have built in RF filtering.

Drive Wonky

A few points that come to mind. 1. The underside of the floppy drive touching a flat surface can cause the spinning stator disk to make contact. 2. You didnt actually boot the PC with either of the floppy disks so although one of them is readable it may not be bootable. 3. SW9/3 on the motherboard is for Floppy drive interface enable and should be set to ON. 4. Try another Floppy cable as it may have a break or bad contact pin. Looks kind of short also so make sure both banks of pins are fully connected to the cable and not just one bank. Would love to see this up and running.

Great video✌
