ZX Spectrum Implemented on an FPGA

- rbanffy 16y agoVery cool! I wish it had NTSC composite video...
- samlittlewood 16y agoIf this sort of thing tickles your fancy, then have a look at http://www.fpgaarcade.com http://www.fpgaarcade.com Several implementations of classic arcade games and home micros are available, and Mike is just finishing up a board for these sort of projects.
- binarymax 16y agoThanks for the link. Last month I found a gem in a charity shop - a first edition of Introducing Z-80 assembly by Mr. Sinclair. Only cost me 10p!
- iuguy 16y agoOn the World of Spectrum forums there's been some interesting posts on Spectrums that are slowly dying. For those that don't know, the ULA was a custom chip and can't be replaced. FPGA technology allows the spectrum to live on in an (albeit emulated) hardware form.
- some1else 16y agoI've got two back home. Is there some reason the ULA will eventually die on it's own, or are they safely stored in the closet for the generations to come?
- varjag 16y agoAll electronics is bound to die as it ages, due to latent chemical reactions. Chances are, ULA will last longer when unused. One problem with Sinclair ULAs is that, unlike e.g. logic gate or CPU they can't be readily replaced by a commodity component. ULA is custom-mask chip produced by order in small quantities, the key issue here is scarcity.
- luu 16y agoDang! I should have archived the source to the Sega FPGA system I made as a senior design project. At the time, it required a relatively expensive FPGA, but that was a decade ago; it would probably fit on an el-cheapo FPGA nowadays.
- flexd 16y agoI actually have one of these sitting right next to me as a i comment along with a original manual.. Too bad i don't have a TV to hook it up to :-(
- pmjordan 16y agoVideo capture adapters are pretty cheap these days.
- flexd 16y agoOh? The problem is that the color TV i have (a older phillips 20" CRT) does not seem to be able to pick up the signal. It worked fine on a really old black and white tv we had earlier. Toobad someone decided to throw it out at some point..
- pmjordan 16y agoYou might be able to find someone on the web who has successfully used their ZX with a specific video capture device. Then buy that same one.
- z303 16y agoNice to see, other people have done similar things for the Amiga [1] and Atari ST [2][3] [1] http://en.wikipedia.org/wiki/Minimig http://en.wikipedia.org/wiki/Minimig [2] http://hackaday.com/2010/01/07/suska-open-source-atari-st/ http://hackaday.com/2010/01/07/suska-open-source-atari-st/ [3] http://hardware.atari.org/vhdl/vhdl.htm http://hardware.atari.org/vhdl/vhdl.htm
