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)...?

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

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

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

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

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.

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

Oddly the Zip files I found none had a manual... Then again I was looking for a TXT or DOC and it was HTML.. Oddly neither Herbs note or the HTML explain why H(val) or HIGH (VAL) does not behave as

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

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

I thought I had the assembler used... ASMZ80? does not digest the following: LD L,LOW LED_DISPLAY_SB? ;Restart Pointer to Secondary Buffer LD H,HIGH SCAN_PTR OR? ? ? ? LOW LED_DISPLAY Best

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

A way late coooment as I didn't see it then... I was a digit, aka DEC employee and lived in the central engineering world. I got to see a lot of really cool stuff. It was available three

I'm running it on X64 linux using dosbox.? A Dell I5 5440 and linux on it is Mint 21.3 64bit. FYI got amsx to run...? it was far to dumb.? I really didn't expect it to be that simple! The Zip had

MyZ80 is an excellent emulator. I wish the code existed somewhere — I’d love to port it for x64. Rich http://cini.classiccmp.org/ Long Island S100 User’s Group Get

Hi Rich, Been doing asm code since my first Altair... TASM I have it.? Good assembler. Its one of the dozen on the AMproLB+, S100 crates (both compupro and NS* horizon chassis), Kaypro4/84, and

One of the assemblers I saw mentioned above is one I particularly like: TASM. Multi-target, multiple host versions (DOS, Win32, Win64). It has been my go-to for over 20 years, although I've used a

Josh, 7400 lines for ZMCV15 according to my editor. The only assembler under CP/M Z80asm (SLR) that wasn't 1005 fail found 3880 lines with syntax or opcode errors.? The other was Z80MR and it was
