1. Questions about ts2068cart

shanedownes · 24 Nov 2017 17:10:38 +

Hi,


 I recently bought one of these boards on ebay, along with all of the components (except for a ROM chip).


  https://github.com/NF6X/ts2068cart https://github.com/NF6X/ts2068cart 


 It looks fairly easy to assemble, but I wasn't sure which type of EPROM/EEPROM/Mask ROM to use, in order to create a ZX Spectrum emulator cart. I don't have the necessary equipment to burn ROM chips, so I was planning on purchasing one of these: http://www.bytedelight.com/?product=zx-spectrum-48k-rom http://www.bytedelight.com/?product=zx-spectrum-48k-rom . 


 Is this ROM chip suitable for creating a Spectrum emulator cart? Do you have any suggestions for an alternate vendor/product to use for the ROM chip?


 Also, is the one in the ByteDelight.com link above, a "Mask ROM"? If so, that means that I would need to set the jumpers on the PCB, to the configuration listed on Github, for the "23128" ROM chip?


 Thanks!
