Its a regular 48k spectrum but guys this isn't what i asked for....
Let me ask again...
Is the right way for merging 2 roms the copy /b command or should i do it another way...(in order to flash the merged file in an eprom). -

The answer depends on what software you're going to use to flash the EPROM. If you don't tell us that, we can't help. -

If the both ROM files are exactly 16384 bytes, copy /b rom1.bin + rom2.bin mergedrom.bin should do the trick, regardless of what EPROM programmer you use. -

hmm, so it looks like the z80 is working at least to some extent.
I'm slightly stumped at this point. Got another rom you can try in it? (a 32kB eprom with the 48k rom in it would do, plugged in in the Rom A socket) -

ZX 48K and TR-Dos?Is it possible that the ZX 48K can run TRD files? I mean is it possible to take a ROM that has TR-Dos inside? Micky
Now I have a +D clone. Works very well. :smile:
What must I do to run TR-Dos files? System is G+Dos 2a. Must I change only the Eprom?
