rfview Hey, what's up guys back again with another video so in today's video. We are going to take a look at an official Sinclair spectrum clone that was released in the US. This is the Timex TS2068 Sinclair home computer The Sinclair ZX Spectrum is over 35 years old It's the machine that defined the term "bedroom coder" and in the UK it started a revolution Now we all know about this machine - Rubber keys, Clive Sinclair, color clash and all that stuff.

But with over 5 million units sold, Its place in history is confirmed and its legacy lives source in its games and its hardware. In the past few years alone there have been a few kickstarters to attempt to revive the machine.

Most of them have failed the Vega+, The Elite System Spectrum come to sinclaair with some exceptions Meanwhile over in the USA the speccy wasn't even a footnote in computer history. In sjnclair Sinclair research partnered with Timex corporation to enter the home computer business and distribute the Timex Sinclair 1000 modeled after the ZX81.

It's fair to say that this wasn't ts0268 very successful partnership with the domination of Commodore, Apple, Atari and IBM. I was lucky enough to pick up this Timex computer, sincliar was graciously donated to me by The Obsolete Geek.

Let's take a closer look at the machine. This Timex Sinclair TS2068 was released in 1983 and is based on the ZX Spectrum 48k I've heard about speccy clones And I guess technically this is one, although you could call it an official clone as it was in partnership with Sinclair Research. This machine was advertised as having color graphics sound and a whopping 72k of memory all for $200.

Zx spectrum usa edition the timex sinclair ts2068 review teardown and comparison Hey, what's up guys back again with another video so in today's video.

This is a little misleading the machine actually has 48K of RAM But with a 24 K ROM for Sinclair Opinion, Atari jaguar story nostalgia nerd apologise and other things. Let's take a closer look at the machine The TS2068 has a 42 key chiclet keyboard. And there's a flap Zx spectrum usa edition the timex sinclair ts2068 review teardown and comparison the right-hand side of the case that when lifted see more expose a cartridge port now There are about seven or eight cartridges official cartridges that work with this machine unfortunately I don't have any to test on this video But there are official cartridges that have games and educational software that do run on the cartridge port and there are specific Timex 2068 games and software that you can buy and run on this machine on.

The left hand side is the power switch and a joystick port and if we turn the machine over to the right hand side There's another joystick port. I can't say I've ever seen a design like this where there's two joystick ports on either side of the case On the back of the unit from right to left is an RF output for connecting the system to a television a power input, which needs plus 15 volts DC,a microphone and the earphone input - these Zx spectrum usa edition the timex sinclair ts2068 review teardown and comparison standard inputs for loading software from cassettes a Monitor out which is just a standard composite and an expansion port for connecting printers and other peripherals this is actually an RS232 serial interface.

I do like the sleek design of this thing the keyboard feels good, but not as good as a spectrum plus, but it's pretty solid Now there are two main differences with this machine compared to a ZX Spectrum Sinclair BASIC was updated with new keywords that https://pikespeakpoetlaureate.org/games/rezero-abridged-short-2-i-still-love.php quite useful.

The "FREE" BASIC command will return the amount of free memory available as you can see in source example. There's also an additional six other BASIC commands that have been included in the Timex machine that Zx spectrum usa edition the timex sinclair ts2068 review teardown and comparison not part of the Sinclair Spectrum BASIC. The second and the more important change is with the inclusion of a cartridge port means that the 48 kilobytes of RAM is Bank Switched.

This is a fairly substantial change from a ZX Spectrum and rendered most software incompatible. Ultimately what you're going to want to do is play ZX spectrum games and unfortunately out of the box compatibility with a ZX spectrum is very low only around 2% or 2 to 5% of compatibility with games and the reason for that is because of the memory bank switching That's found in this machine Which doesn't exist on a regular ZX spectrum and the reason for the Bank switching memory is for the cartridge and the ability to load cartridges on this machine and unfortunately that causes compatibility.significant compatibility issues with a regular ZX spectrum.

So in order to increase compared ability with ZX spectrum there was actually an official cartridge which emulated a ZX Spectrum 48k Model machine that you could buy and plug into this machine via the cartridge port now unfortunately They are super super rare and impossible to find and I ghibli movies worst to best there's only a really only a handful of them ever made however There is a solution and that is if we Ps3 10 years later the custom ROM image That's found in this machine with just an originals that expect from 48 K ROM That's found in a regular ZX spectrum machine, then compatibility will increase significantly So let's take a look at that now.

So of course as always let's crack open this machine and take a peek at the internals Now just turn the system over and with a FlatHead head screwdriver.

There are seven screws You will need to remove take note of where they all go because they are not all the same size now once That's done turn the machine back over and gently lift the case You will notice that the keyboard is attached via this ribbon connector Just remove it and that will expose the motherboard.

There is no RF shielding or anything else like that in this machine So let's take a look at the internals of the machine These two chips are the ROM chips the one on the left is the Sinclair ROM chip And the one on the right is the customized Timex extended ROM, which go here the extended basic commands I talked about previously as well as other functionality The Z80 or "Zed"80 runs at 3.52Mhz which is slightly faster than the 3.50Mhz of Zx spectrum usa edition the timex sinclair ts2068 review teardown and comparison PAL 48k Sinclair Spectrum.

The sound chip is the AY-3-8912 which is the same chip, that's used in the ZX Spectrum 128k Next to that is an internal speaker, and there's no way to adjust its volume These are the DRAM chips that make up the Timex Sinclair internal memory This is the Timex SCLD chip, and this is the chip that's responsible for the color generation in the Timex computer Now one thing I do want to mention is that these wires look like an aftermarket modification has been made but in reality This is a factory stand and this is what you get out The review game sack the box when you open up the motherboard and take a look at the internals Okay, so how do we convert this machine to be more compatible with the ZX spectrum well It's pretty simple really just remove the Timex, Sinclair ROM from its socket Just use a Phillips head screwdriver and gently remove this chip and in its place you swap in a ZX spectrum ROM chip I have a burnt image that I'll be using for this You can keep the Timex Extended ROM in place as it.

Won't be Referenced and this is all you need to do in order to make this machine more compatible with the ZX spectrum But please note cartridge games will no longer work Now if you've uses a tech spectrum before there are a couple of things you'll notice very quickly The first one is click at this page colors are different than what you're used to and this is because of the scld chip generation which generates the colors in this machine It's slightly different than the ULA chip in the Zx spectrum usa edition the timex sinclair ts2068 review teardown and comparison Spectrum and the other thing you'll notice is how noisy the composite signal is and this is actually not a hardware fault or something Wrong with my machine.

This is not a dry solder joint or anything like that This is how it is out of the box. Now there are some modifications that can be done to address both of these things you can actually do some Modifications to get a more authentic color palette as well as an s-video mod to get a much better video Signal, and this is something that I'll probably look at doing in a follow-up video But for now here are a couple of examples of some ZX Spectrum 48k games loaded off cassette that are running on the Timex Sinclair 2068 Well guys, I hope you enjoyed my review of the Timex Sinclair TS 2068 home computer Let me know what you thought about it in the comments below as always don't forget to Like and subscribe and check this out my North American friends have a safe and happy Thanksgiving, and I'll catch you guys in the next final, Terrifying joker from gotham revealed in finale promo agree bye for now
