Excellent timing, I have just hacked my 32KRAM + 8KROM board to take the bigger 28C256. So I can now have Grant Searle's NASCOM Basic and ZEN resident. Will use the Z80 block load to move a binary copy of ZEN from ROM down to RAM @1000h.

This mornings pain has been generating the binary, after some searching found a somewhat ancient application called srecord that will take almost anything in and general almost anything out. After dusting off the memory cells to work from the DOS prompt have got the binary which I can now 'glue' on to the basic binary and program the 28C256.

I know it is a long way around but my memory board is not designed to allow me to in situ program the EERPOM - it was originally design to take an EPROM
