Re: What ZX81 Basic compilers there are out there?
Hello, for your first question: There is MCODER II and MCODER (former ZXGT) and I found ZX-Compiler by Silversoft but never got it to work even after trying to understand the BASIC Listing... Then there is Autocoder and BASIC-I-Compiler, which i try to find but never found it (written in BASIC) and...

What ZX81 Basic compilers there are out there?
Hi, I was playing with MCODER II, it works well I guess, although when I want to use the routine for deleting the basic lines (LET L= USR 17281), it sometimes work and sometimes crashes, I don't know why. (I'm using a ZXPand, maybe it gets things weird?) There are other zx81 basic compilers out ther...

Issue with keyboard, now it's working ok but...
Hi, I had a strange problem (strange in the way that it came). I was playing with the zx81, with no problem at all, and then started trying with a 16K RAM that I knew that worked, but the RAM didn't want to work, I started the classic "plug the RAM, curses, turn the computer off, move the RAM, try a...

The stupidest thing that could ever happen to a ZX81. Help!
Hi gurus, this is my sad, sad story. I was trying to change a keyboard on my ZX81. I took off the old one, under it it got a sticky layer of old-time glue. I tried to clean it up, but it was hard to remove. My wife suggested me that I could use this nail polish remover with acetone. I did, and a dro...

Re: Question, how do I write to memory through the expansion port? Possible?
Thanks for the responses, guys, I will try Arduino then, I assumed that Raspberry used 5V logic. Where can I find more info on how to do the "charging" of the bytes? I mean the process itself, I know close to nothing about it, Where can I find some specs for the expansion port?? I have searched but ...

Question, how do I write to memory through the expansion port? Possible?
Hi gurus.
I think the title says everything. I have a Raspberry 3 and a couple of bad memory packs that I could destroy without remorse, is it possible to build some circuit and use the Raspberry GPIO to load a .p file directly to memory? there's something done?
Thanks in advice!

Re: question about SCROLL
This made me remember another thing: I noted that without the Memopak, when I press Break when I just type LOAD "" (without starting to load), I get the "D/0" error, which is OK, but when I do the same with the memopak plugged I don't get the error, but a space and the K, like I just wrote a space.

Re: question about SCROLL
In fact, the SCROLL function is bugged on the Zx81 using a 16k ram pack! You, sir, are right! I took off the memory expansion (memopak 32k) and the behavior doesn't show up. It has to do with the different DFILES formats in 1k and 16/32k, as you showed. I don't want to use the scroll for anything, ...

question about SCROLL
First of all, sorry if this post doesn't belong here, but I didn't know where else to post it and I am curious about this since I was a child. Given this program 10 PRINT AT 21,0 "SOMETHING" 20 SCROLL 30 GOTO 10 If "SOMETHING" is a string of 32 chars long and I let the program run until fillling the...
