Re: FORMATTING THE uSD
If it's not FAT16, the SD Init will fail and let you know it's a bad partition type.?

Re: FORMATTING THE uSD
Problem solved... Used a old(CA 2004) Compaq pentium based machine running
NT4 that would do FAT16.
However the drd was already formatted fat 16.
Solved.

FORMATTING THE uSD
The supplied uSD with the Z80MC according to the docs must be formatted FAT16...
Mine out of the box has a label Z80-SIO... a good thing but was it formatted to FAT 16?
If not I have one more system

Re: A Z80 Asm rec
Need to find out how ASMZ80 does it.? Perhaps you will need to mask the address and shift it?
LD L, LED_DISPLAY_SB & 0xFFLD H, HIGH_SCAN_PTR >> 8
Need to read the ASMZ80 manual to see how they

Re: A Z80 Asm rec
Never mind...? Even if the cross assembler were right I'd still have to heavily edit

I'd briefly considered feeding the ZASMV20 to BDS C compiler but it

Re: A Z80 Asm rec
I thought I had the assembler used...
ASMZ80? does not digest the following:

LD H,HIGH SCAN_PTR
OR? ? ? ? LOW LED_DISPLAY

Re: Z80 1st boot (wooot!)
Just a note there were versions of CP/M late in the game for Z8000 and 68000
that were the basic system written in C.? It turns out the 68K? had a instruction
set remarkably close to PDP11 and VAX

MyZ80 is an excellent emulator. I wish the code existed somewhere — I’d love to port it for x64.
