Re: SD I/O 1.8MHz resonator
I order parts off of eBay. In many cases, the supplier will ship, as Paul stated, via a "package bundle". Sometimes U.S. vendors do the same thing using DHL or FEDEX. Recently, I've seen the Chinese

Re: SD I/O 1.8MHz resonator
Judging by the tracking on my two recent orders it appears that they bundle US (or maybe North American?) orders over some interval into a single package that is shipped to Colorado where it is

Re: SD I/O 1.8MHz resonator
Oh great Lee. I just did my 1st order with them as well for these 1.8meg cr's for my new z80 bd. How long did it take to get them? The shipping was very reasonable.

Re: SD I/O 1.8MHz resonator
glad it's working for you. Did you try other fixed baud rates? ________________________________ Sent: May 27, 2021 1:54 AM To: Z80MC@groups.io <Z80MC@groups.io> Subject: Re: [Z80MC] SD I/O 1.8MHz

Re: SD I/O 1.8MHz resonator
FYI: for non-standard baud rates; I use Linux for all development work and?a USB-2-TTL serial converter for serial I/O. I tested with with CH340 to see how much baud-rate error would be tolerated at

Re: SD I/O 1.8MHz resonator
Hi folks! Just a quick update, it actually works if your terminal client supports custom baud rates. I got my kit fully assembled this morning, and had it working? in no time using GtkTerm under

Re: A Z80 Asm rec
Z80 is 4-22 clock cycles per instruction. The longer ones are the are in the groups that increment or decrement and repeat. For Z80 the simple way is a RST (one byte call) to one of 8 locations. The

Re: A Z80 Asm rec
I just wanted to give a recommendation for the ASXXXX family of cross-assemblers, as I use them regularly. They are full-featured, open-source, actively updated, and work well for a very large number

Hi Allison, You've had a lot of experience on assembler, I wonder what you think about how flexible assemblers should be?To be exact, let's talk about the Z80 here.? Forgive me if I can't remember

Thanks Scott, I'm just looking at all the options you list and can only say WOW is there ever a LOT of software out there!So much software, so little time! Cheers, Josh
