With those keys that were yellowed on the sides, I would be tempted to just wet sand the worst of it away. It wouldn't noticeably affect the texture, and since it is on the sides rather than the tops of the keycaps, it wouldn't hurt the legends.

I don't think fakes. we don't know what's going on with the manufacturers. this technology is not 100% perfect. When a manufacturer receives an order for 100 thousand pieces he must require the specifications published in the data sheet. he will start production. he will test each component. So out of 100 thousand there must be at least 15% which are outside the specifications. he will put them aside so 10 thousand pieces will be thrown away? these parts are functional..but slightly offset. crazy it works crazy it doesn't work.

It is fun to think one day people will likely be emulating present day computer hardware on computers with many TB or RAM and petabytes of persistent memory and hacking to the very limits of addressable memory to get performance and run software that is completely unaffordable in 2024.

Wow, such a great video about an 8-Bit computer I new next to nothing 'till today. Super professionally done, and, man, such a pleasure to see you tested and played the games first, and then shot the video!

My favorite thing to use my HV probe is with my older arcade monitors (MS8-26). The sound of the charge draining is really satisfying.

This was so bad. The Vic20 is about 2.5 years older than the C64, having come out in Japan in 1980. You call the C64 it's older brother. Then, the Atari, whose clock is about 78% faster than the other 6502 machines was the slowest at 50 secs yet you claimed the C64 was slowest though it took 40 secs. And you never even said which basic was used on the Apple- there are 2 different versions.

That's probably because you grew up with it .. others grew up with Spectrums or MSX or even C64 and it is their absolute favorite ;)

"WHAT DO YOU TOOLS NEED?" Reads the thumbnail. C:

I really loved our Amstrads that we had when I was a kid, I spent many years programming on it from '84 to around 1990 when I got a C64 in my room.

The pack of components required, with the CPLD already programmed... is there somewhere where we can purchase those?

4:00 The chance a new TV has RF today is 10 times bigger than the chance it has composite input. Even those 8K OLED's prefer RF above composite. Thing is a modern TV most likely has a DVB-T2 tuner or a DVB-C tuner. Both run over coax. And the chipsets decode analog RF along with the digital formats.

Nice video. We are making a 2MB expension for the Philips P2000T, a Dutch Z80 machine, internally, as it has plenty of room. 2MB is the limit, as the OUT toggle can deliver 256 positions for the upper 8kB of RAM. So you get 2108 kilobytes. Actually back in 1988 someone already made a 2MB expansion for this machine, byt with 256kbit chips (64 of them!): the use was running a BBS over the Viewdata protocol. They needed to upload 5 floppy's with all the user messages and such into the RAM, and they even managed to run it for 5 years without a single power-down. Our modern version has 4x512KB chips and TTL logic. Still it is pretty compact. What is weird though, the C128 does flip the entire RAM. Must have been hard to swap data between the two halves on that machine.

Hi, Sorry for being a noob here but what type of wire did you use? Is there a specific size or type I would need to do this mod. Cheers.

hello, I love your project and your videos 😊 In my research to improve the use of our cpc in 2024, and always for a reduced cost or with recovery elements, I use a bluetooth module, recovered from an HS audio headphone, the first module use bluetooth to communicate with a smartphone or others and the second module I use the micro SD reader part. My castman channel on youtube. one of the two videos: kzfaq.info/get/bejne/Y5iDdZyl09jRhIk.htmlsi=XO6abcG7eC0JSAbd 😂

Tldr for anybody trying to build a lab don't buy everything at once you don't need 20 multimeters two oscilloscopes two bench power supplies Try your luck with whatever you got right now if that doesn't fit your criteria or breaks easily or broke quickly then get a new one get a proper one Don't go out buying the best the most expensive if you do maybe 2 hours of soldering in a year Go by what do you need currently for your current project Everything else is going to accumulate really really quickly

Depends on kind of work, but as a kid (1973) i repaired and played with radio's and televisions with just a 25W iron and borrowed screw drivers. Then got a very cheap analogue multimeter. I got into building transmitters so bought a £8 SWR bridge for an indication of RF power, then next a Taylor RF signal generator i found at a jumble sale to work on shortwave receivers. Was 1978 before i saved up enough for a 600MHz frequency counter as by then was building phase locked loops using logic chips to control transmitter oscillators. Always stuck to analogue and done a lot with valves. Love the things, especially in high power transmitters. Microprocessors leave me cold but forced to delve into it sometimes.

How much it cost in total?

But using a 32 bit, 240 MHz processor for i/o is beyond cheating, if you take it by the title of the video, right?

Hunt the Wumpus!

Your contact's statement about cheap tape decks working better than expensive ones is supported by the Timex Sinclair 1000 user manual. I'm hoping to put this to the test once I've finished repairing my Sony hi-fi deck. Right now, I have a Panasonic shoebox deck from the 2000s which doesn't work too well, and a Timex Sinclair cassette player that does the job when volume and tone are around 7-9.

There are glasses like that which allow you to clip on multiple lenses simultaneously.

Is this true ?

Can you use this to attach a cdrom to a 8 bit computer

Install 1gig of ram

Those "fake" chips are like the plague. In fact, they often are genuine but inferior components with other specs that are rebranded, when not outright duds. That shows how China is corrupt. I even would bet that the Chinese government is funding the flooding of the market with these chips. So much so that even reputable distributors may get them unintentionally. What a cancer!

Is there a budge option? The 6128 seems rather expensive, and the disk drive is so obscure, it will be hard to get working disks for it. I do like the fact that its Basic has an EDIT function with working insert, that is really special, only seen in my favourite machine the Philips P2000T. That one shares a lot of your preferences, except it is very bad in graphics, but that is no big deal IMO, as I don't get home computers for games, a NES is a clear winner at that, not to mention my PC Engine from 1987 destroys any competition. My reasons I like the P2000T: - RGB output, super clean text and colours on a cheap compact Trinitron. - The micro-tapes are super fun, and do automatic loading/writing. - Affordable - Very easy to maintain, and bullet proof. Hardly any wear, even the tape-drive is rock solid after 40 years with no belt wear as it has no belt. - Built in PSU, no external brick. - Room for expansion inside - Great 80 column mode without loosing colour or compatibility (still 8 colour). - Great looking case - New hardware comes out, like 2MB RAM expansion. - Excellent BBS/Viewdata terminal

Philips P2000T (Z80): 46 seconds

wow this must have taken an incredible amount of work. Thank you so much for doing this and sharing it with the retro community 👍🏻

Dirt cheap shipping from China is subsizied by western countries through the International postal union because they still have "developing country" status. This counterfeit garbage puts strain on our postal services and ultimately makes it more expensive for us to purchase and ship stuff domestically which strains local industries even more in favor of people buying stuff from China. If the sellers make a profit every now and then from someone storing a chip and not using it within the refund window: great for them. I don't think this is primarily a profit making operation, I think this is a way of inundating and weakening foreign postal services and economies much like Temu has.

Noel. Where are you?

Thank you for explaining everything in such clear and detailed way!!! This is by far the best ZX Spectrum video I have watched so far. 18:23 Where can we get a t-shirt like that?

We'd have absolutely loved this game back in the day. These days loading cartridge files (C64) or disk images is better, and TZX files, in the case of the ZX Spectrum. However, this device is a nice option if you have real hardwares.

Noel do you ever have any issues swapping between disks? I've installed a Gotek in my PPC512 today. When I swap between disk images, the computer doesn't detect the change. I'll swap a disk, type DIR and it still lists the contents of the previous disk, not the disk I swapped to. I'm guessing this might be a disk change detection signal issue?

How is the flashcart for the svi-328 project going? any progress??

If only the amstrad cpcs had an extra chip dedicated for animation... It would be the undisputable winner of 8bit era. At least in Europe I believe. How much would that increase its cost I wonder.. My favorite computer to this day is the cpc 6128 even if I'm the proud owner of a cpc 464 with a green monitor! For some reason never owned a 3" disk drive unfortunately to go closer to the experience..

I use my fluke every day

A Phillips VideoPac, nobody else has ever heard of one of those. My Stone Sling cheats.

no

I once heard of a person who would place a handheld AM radio receiver near their computer to listen as programs would load. I think it was one of the TRS80 models, which had notoriously noisy RF.

Why u forget function genertor is equiment for electronic engg

Was that a esp32 on there?

I need DC power supply and multimeter

Do you use and Amstrad Plus computers? I really want to get mine running again. I think the tape deck is the main part that needs to be fixed. Similar to this model I hope.

Great job

If an 8-bit computer took steroids..
