Mitch, Can you please tell me if you are using all 3 boards? or just the Front panel with the Z80?Also, how are you powering your Z80mc??? FYI, I'm using all 3 boards and powered from a 5V, 5A

Strange, I do not see that issue either. I'd suspect a button installed wrong or a row colum short. Allison

When though full install of the SDCC on my main linux machine. Reason was to find out in the flesh if it was batter than native... The answer is, not really.? While its faster, the code pushed

What a strange problem.? Not happening on my system.? I tried 2888 and 7888 10 times and got the right number every time.

It's funny you mention a problem with the #8 button. I have a similar problem with mine. Instead of getting 8, I get 9. Spent a bunch of hours troubleshooting. Never figured it out. Sometimes it will

Thank you Allison for the detailed and enlightening information, appreciated. I ran into some problems assembling my Z80MC. Everything was assembled, including the z80 SIO, verified several times and

Original Dunfield's Micro-BASIC program used a monitor also from David Dunfield.? His site is still up but the URL is different. Note that there are two versions of that basic one in .ASM

Here's his unmodified assembler code for Micro Basic.? You should read his comments, he's very funny. Also, here's the modified code with the extra INP and OUT commands added.

Hi Josh, Unfortunately my Z80MC Front Panel had an issue with an IC, so currently it is waiting for a part. In the meantime I am somewhat familiar with Micro Professor MPF-1 Tiny Basic. The system has

Kerem, I should tell you, I added 2 instructions to Micro Basic.? OUT and INP.? OUT pp,vv? works to output byte vv to port pp. And INP(pp) is a function that returns they byte at input port

Hello Josh, Thank you very much. That’s what I was looking for. Excellent. Regards, Kerem [email protected]> wrote:

Hi Kerem, Hmm, I wonder what happened to the website? Here's the MBasic Manual I downloaded. Cheers,Josh Bensadon

Dave, I was there from the start 8008 in '73 and Altair8800 (8080) December 1974 I was early adopter bleeding edge sort. Period pieces...? Yes they are old but still work as they did then..or

Hey, that's awesome! ?Amazing to talk to someone who was there for all that. ?Even more amazing that you are still doing it on period pieces, with period software! I hadn't heard of the tools you

Hi Dave, I know SDCC is PC based but it inherent PCisms are notable. Its compiler does not produce great code.? It works and runs but you would think on a current generation PC there would be

Mark, That is the exact one I have. got it because it was small and had capability matching some of my larger machines.? Indeed nice kit.? Still putting my usual work stuff on it.? Turbo Pascal

The z180-based pocket computer (I have an essentially identical one called the " Elite SC131 ( https://www.tindie.com/products/tindiescx/sc131-pocket-sized-z180-romwbw-cpm-computer-kit/ ) ") is indeed

yes, indeed, SDCC is PC based, and may not be to the taste of those wishing to be period-accurate and develop on the target systems.? I imagine the vintage compilers are all K&R style?? I should try

That whole process looks to be all PC based/biased. All C code for CP/M? and 8085/z80 I do is using native tools on CP/M systems.? There more than enough disk (uSD) and ram to?run all the native

Dave, Started using C back late '79 using Ron Cains SmallC and soon after BDS C natively on Z80 system. Also have HighTec-C and Nevada C.? Never thought to use SDCC.? However all of the compilers
