Would the Composite Video mod for the 48K Spectrum, work on a Spectrum+3. I am hoping the modulators in the +3 is similar to 48K machine.
I will have a go and report back
Seen a Plus 3 on ebay, with a 3.5" disk drive fitted.
I always thought this would a good idea. But this make the computer incompatible with 3" disks.
Another thought would fit an ST Card reader in place of the disk drive, which is the best.
I put the IF1 rom in my All03a programmer and set the software to TMS2564 and rom was read into memory.
I have got 2 x TMS2564 eproms coming from Germany only £6 each.
Pity a static ram chip could not installed so custom rom images could loaded.
I have an Interface 1 with a version 1 Shadow Rom, I would like to update it to Version 2.
Does anyone know where I could get a rom image of Interface 1 Version 2.
I read on Dataserve Retro site that there maybe a version 3 rom, was that ever released.
This looks like the Spectrum laptop using a similar 7" LCD screen, there is also a 9" variation.
I did track down the author's website and download a hardware manual for Spectrum projects, which some could be applied to the ZX81, maybe...
