Hi Lee, Thank you so much for your reply and kind words. It was a real rookie mistake Lee. Not only new to this connector but new to the type of flux I got from ebay a few months ago too. It was a

OK Completed the SIO board today! Like the above comment, this is really a great Z80 machine. Here is the finished board as well as the 1st listing entering into C/PM enclosed. So cool to see that

Now here is the CPU and the Font panel display keypad system. Woot #2!! Just finished it today. Had a bit of issues with glitching at 1st even though I did replace the 74LS245 with the 74HC245 I

I think thats why I love all the stuff Lee (and you) have done here. When I was 13 I got some kits from Heathkit (and Eico) and I think that was so wonderful to do and explore. I knew crap about

Tony, That's all Lee.? He's big on taking little steps.? He's always going on about grand builds that start at the bottom.? Building modules one at a time, testing them individually then combining

Thanks Josh, Yea it was the Additional Operating details with ZMCv15 ROM you and Lee wrote that really helped alot. I saw how you guys set it up to test only the Z80 card by itself that got it working

Tony,? looking good!?

*Here is the 1st boot of just the Z80MC CPU board!* yippee! Finished it last week but it had no clock. Found out that my use of a 74LS368 was not a good Idea, so I put an order in to Mouser for an

I’ve also seen ORANGE CONNEX on a few occasions. I’ve signed up for USPS notifications so that as soon as any package enters their system that targets my mailing address, regardless of origin, I

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

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

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.

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

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

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

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
