Re: FORMATTING THE uSD
Its not clear in the docs or I have to reread them... I assume the process is to use the PC to copy the contents bigboot.zip after extraction to the uSD and that's it. Allison

Re: A Z80 Asm rec
Hi Herb, Happy New Year. The version I have came from your site.? When I need things micro, its on my list for many decades. No idea but its possible when I tried to assemble it (and install) a

Re: A Z80 Asm rec
This is Herb Johnson. The HTML document file in my ZIPped asmx distribution is a copy of a similar file in Bruce Tomlin's asmx distribution. My copy has changes which represent the changes I made in

Re: A Z80 Asm rec
Hello folks, I'm Herb Johnson, the distributor of a version of Bruce Tomlin's great asmx cross assembler. It was called to my attention, there was a discussion here about "my" asmx, Bruce's asmx, and

Re: FORMATTING THE uSD
Te St506 predated the st225 by about two years.? I have a few of the latter as they were free (RD 31 and also St250s RD32).? I prefered the RD52 Quatum drives much faster and more reliable.? I

Re: FORMATTING THE uSD
I think I've seen an ST506 back in the day... but for the most part, I was playing with ST-225's on PDP's.? 20Meg was very nice but still not enough for any large systems. For the big 8Meg disks, I

Re: FORMATTING THE uSD
Hi: If I comprehend the question, you're not sure how to tell what file system the SD card is formatted for? And further, how to format a partition as FAT16? On WINDOWS, go to "MY COMPUTER" and
Re: FORMATTING THE uSD
Thanks Lee. I used parted to examine the uSD and discovered it was basic fat 16. I come from a time when a ST506 (5MB) seemed like more space than usable.. That lasted maybe a month.? Most systems

It apparently does but that is not helpful. Man page on my system says the same thing save for I get... :mkfs.fat: unable to open /dev/sdb: No medium found Same for all variants of? sdb (stick)...?

Re: A Z80 Asm rec
I used DRI's MAC80 and Microsoft's M80 for most of my Z80 programming. Later I got the SLR180 assembler, which was the fastest and most versatile Z80 assembler. I used it to write a lot of code for

Re: FORMATTING THE uSD
Hi Allison, Yes, the SD-card has to be formatted FAT16. This is also why you can't use cards over 2 Gb. It's hard for me to imagine needing over 2 Gb on a computer as small as the Z80MC! Since small

Re: FORMATTING THE uSD
I'm pretty sure mkfs.fat will create a FAT16 disk -- from the man page, "mkfs.fat? is? used? to? create an MS-DOS filesystem under Linux on a device". -Bob

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

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 the code for a CP/M native assembler. I'd briefly considered feeding the ZASMV20 to BDS C compiler but it
