ZX Spectrum running 14Mhz

[10p6]

It's strange as the tape loading speed on the Spectrum was not limited by the CPU....

[Peterkearney76]

back in the day i used to half press my pause button and the tape deck would run 2 x speed and it worked

[blkpntr]

Try "Critical Error" demo on this machine :)

[jontycampbell]

So if I recall, the Z80A CPU was 4Hz?

[Pwnedanime]

lol thats a middle finger to old school loading screens :)

[OGRMaster]

This is freaking cool!

[leonidy1985]

спринтер 2000 работал на частоте 21 Мгц

[jjovereats]

Can you find me a keyboard smaller than the ZX's, normal laptop layout, and larger than the Eee PC? Facedarn!

[receptor1974]

И толку от это хуиты?

[yurigglutube]

@receptor1974 А в чем для тебя толк? А толку с чего либо другого?

[felleice]

Now that is a computer!

[Kuula10]

Wow that would Run Doom more faster and better

[wootlanter]

I did actually notice that my spectrum +3 can load tapes being fed to it sped up. And I didn't overclock the CPU. But when you think about it, the disks could load up about 50 times faster than cassettes. And yet, the +2 and +3 were pretty much the same, save the disk drive. So the question is, why weren't they able to have fast data transfer with the cassettes for the +2? I imagine it was because they wanted to make it backward compatible with the 48K. But then again, even that had the same CPU

[absinthedude]

@wootlanter There is a limit to the amount you can speed up an audio cassette, speed it up much more than 1.3x normal speed and the frequencies are too high for the heads and amplifier to correctly send the signal to the spectrum. The turboloaders were at the very edge of a sandard cassette recorder's performance.

[wisteela]

Nice way to do it.

[TopTellyFan]

Blimey! That's incredible!!

[Pugragger]

Z80 <3333

[lastofavari]

ZX Spectrum rulezz 4ever!!!

[angelofdarcness]

помню, магнитофон, телевизор и spectrum и полчаса пииииииииии а потом играл в самолётики, ээх хорошее было время

[mig189189189]

Awesome video. Keep on with that good work!

[raven8dragon]

Great choice of game!! I love listening to the siren song of loading tape...:D Thanks for sharing this!

[mariodivine]

14MHz CPU require redesign memory multiplexing block and make changes in ULA. Unchanged ULA stopping system when need access to video memory! If u want increase speed of CPU u must build additional latches on side of ULA and CPU... THIS VIDEO IS RECORDED ON NOT REAL SPECCY! If u want load files faster just use TZX converter! I use mp3 player 8000 bps loading!

[nicolunacba]

amazing!!!! really fast and powerful! How many ram? :D

[receptor1974]

Дрочь

[silverljus]

... i'm getting goosebumps from the loading sound, i miss my spectrum zx80 :D

[maiki60fps]

rather than overclocking Speccy to 14 MHz it would be nice to see some handy video hardware like HW sprites and more colours onscreen... a complete redesign of ULA chip is the only step forward

[VectorOmega]

And less or no colour clash. BTW, the Spectrum would need a newer machine language coder to handle the extra colours and sprites, etc. Or a special language programmer.

[bar77FUL]

Teenager

[bobdole57]

HAHA thats hilarious.

As a teenager, I guess I'm lucky to know about the days of cassette storage.

[Urko2005]

@bar77FUL oh yes those were the days, its all we knew mind , i wouldnt go back.

Used to wait for 10 minutes for a game to load and then it could crash right at the last second of loading lol

[miguelgaio]

@Urko2005 So true...and now we have the ps3 and a load seems to take forever. Its time relativity right there for you to see!

[crocz]

Yes, why not :)

[k1m0rec]

Damn ! Thats waz hot !

[eugenealive]

I had a speccy with such feature 15 years ago. it had additional basic command - "TURBO". Simple executing of "TURBO 2" or "TURBO 3" had the same effect. "TURBO 1" was returning to default freq. And it could load games with 4x increased speed in this mode.

[oiisee]

that was just turning on turbo-mode for tape-loading operations, not for the whole computer including CPU/RAM frequency.

[eugenealive]

That's right. The games speed remained the same.

[McGuywer]

That's not true. There's no separate tape-loading chip inside the Spectrum. It was the CPU that constantly read the 1's and 0's from a specific port. Where it didn't understand or the tape was damaged, or simply the head wasn't fine tuned on the tape for a clear sound, the CPU displayed the dreaded:

R Tape loading error 0:1

message, and you wasted another 5 minutes of your life.

[alex76gr]

Speccy on steroids !!!

Super !!!

[mykpdotcodotuk]

thats excellent, I wish I could have done that 26 years ago, might have saved me a few years worth of time waiting for games to load.

[remicont]

Ваще просто рулеззз. Вот бы щас в саботёр 2 погонять и эти звуки загрузки услышать.

[manel444]

old times,great days i spend around this noise.

[vasquez109]

Awesome!

[stevenbenjamincole]

As Bukster says below,formulate idea, construct plan, implement solution. Do it why? Because you can....good work mate :)

[smidsyonfire]

...Love it.... thats quicker than loading Windows XP... Who would have thought it !

Great job

[motorade]

Cool :D

[bukster1]

I've always liked people who are crazy enough to come up with ideas like this, but are also smart enough to actualy pull it off.

Great work. I'd love to have a look at how you did it.

[polarsequence]

Overclocking a speccy, haha, nice one! :)

[yukatanDX]

now run crysis in the spectrum and you wont be wasting your time

[alizta]

So hacking hardware is waste of time, learning wicked engeneering skills in the process, while mindlessly shooting people in a crappy game is not? Seems some people only have their brains to keep their heads warm.

[Karpens16]

nice burn!

[sdfdzsrgh]

FAKE!!

la grabadora de windows al subir la velocidad de un sonido mantiene el mismo ancho de banda por lo que se pierde parte del audio, perdiendo a su vez datos del juego haciendolo inservible.

Podeis probar abriendo cualquier cancion con este programa incrementando su velocidad en un 700% , por ejemplo,y despues volver a bajarla en un 700%, al escucharla notaremos que se ha perdido calidad en el sonido.

[dadrowcorp]

Para unos datos que se cargan a 1500 baudios la perdida de calidad de sonido no influye para nada.

[dadrowcorp]

sdfdzsrgh: Para unos datos que se cargan a 1500 baudios la perdida de calidad de sonido no influye para nada.

[sdfdzsrgh]

bueno eso dependiendo de cuanta calidad se pierda,

y si cada 0.66mseg se produce un sonido, en una carga normal, que la maquita debe reconoce, muy posiblemente que al reducir la calidad 4veces parte de estos datos se pierdan o se hagan irreconocibles para esta..

para hacer lo del video primero habría que aumentar la frecuencia de muestreo del audio tanto como sea necesario para que no se produzcan estar perdidas

[cuco1271]

ole tus cojones

[V00nster]

Heh, still takes long to load :-). I miss my Speccy.

[8bitRulez]

The C64 comes with VIC2 graphic processor and some 3 auxiliary chip. Speccy does all with Z80 and ULA!

[pw3uk]

Fantastic!

[TricoL0rd]

Great!!

I remeber my old TK-85 (brazilian clone of ZX81) had a fast loading command too. That was "RAND USR 8630" for "hi-speed loading"

and "RAND USR 8405" for "hi-speed saving"

Great vid! Amazing upgrade!

[netwalker72]

Yo tenia una Spectum+ y las cargas en turbo daban un trabajo terrible...solo el VIGOCOPY 2 las agarraba...

[gthreek]

BBC Micro with secondary processor via Tube connection is superior. :P

[thomson1974]

Foebane72 - you know nothing!

[Ohsky1]

that reminds very old times in my life, when i was 5-6-7 yrs old.

[ozzy]

Fantastico!!!

[robertgraff]

ha ha u geek!!

[rogerjowett]

sam coupe anyone

mayhem accelerator 24mhz and data gear dma interface atom ide

[miguelgarciataibo]

excelente!!!

[stevebasset]

From what I can see it is a separate CPU board? So, when will it be released?

[level42collector]

Nice !!

[dron48]

мясо, детсво было прожито не зря

[1337Shockwav3]

Just why? I've seen in the video that you used a clone (forgot the name for now) which incorporates a CF reader.

[guygittins]

Love it. i cant imigine what jet set willy would sound like at 14mhz!!

[VideoJunkei]

play that game at 14!!!

[OOverflowW]

WOW !! great hack !

[keeprighton2007]

just one question - why?

[DingKong]

Impressive, most impressive...

[freddo27]

I used to spend several minutes loading that game from tape, only tpo get the infamous "tape loading error, 0:1" message. Great demo of a hyperspeccy!

[wisteela]

Superb!

[yaKC]

I want one !

[tankblaster2k]

make a nice firewall

[zxspectrum128]

It's the ZX Badaloc, a new spectrum clone.

[CyberMSX]

Impressionante. Quero fazer isso no MSX.

heheheehhe!

[zxspectrum128]

Awesome. I know about russian clones that run faster. But I'm intrigued about your setup (Which Spectrum, Which pc apps, how are they connected, the switch you used). Details please. :)

[DJOlaf13]

please tell
