I know it's not as nice as EightyOne, but there is 64 bit SZ81, which should run on the Apple M1, though I don't have an M1 to test with.

Re: Why is the RAM Pack so terrible?
And I'm not talking about the wobble. I've got a stock Sinclair ZX 16k RAM Pack, and right off the bat I had to replace two of the 4116s because they were clearly bad (found out with a logic analyzer, wouldn't start otherwise). But now I accidentally left the ZX81 on over night, and when I came bac...

Re: VLa81 noisy video signal
Hi, so, last year I solve to fix a TS1000, my first computer, broken 35 years ago by my girlfriend. As the RF sintonizer doesn´t finded any video signal from the computer I made a video mod (the one with NPN transistor, 100 Ohm resistor and 100uF decoupler capacitor). The computer didn´t give any v...

Re: How do i get a movement on screen using the ZX80
You can do it in BASIC using text.
The word hello will go back and forth and advance down the screen.
Code: Select all
10 FOR Y=1 TO 10
20 FOR X=1 TO 10
20 PRINT AT Y,X;" HELLO "
30 NEXT X
40 FOR X=10 TO 1 STEP -1
50 PRINT AT Y,X;" HELLO "
60 NEXT X
70 PRINT AT Y,1;" "
80 NEXT Y

Re: Took Apart My TS1000 - I Have Questions
It’s interesting that your TS1000 has a 2C184E in it. That blows out the idea that these were all fitted with the 2C210E ULAs, and hence they all have video outputs that include the ‘back porch’. Mark My TS1000 came with a 2C184E ULA. I had video issues with it back in the day, dark screen on my TV...

Re: Took Apart My TS1000 - I Have Questions
Which ULA does it have? The same as in my ZX81, the 2C184E. This on was made in the 10th week of '82 per the date code (that one was made in the 26th week of '82). I swapped ULAs to see if the RF would improve but sadly, it didn't. So I've already removed and gutted the RF can and have one of your ...

Re: Video conditioning mod issues
If you upgrade the ULA to version 210E or one of the modern replacements you should get good video. I use a legacy 210E ULA and run the original RF modulator and I've never had video issues.
