Re: Video Timing

Perhaps it might be worth adding a line of total adjust before and after the main 256 lines to allow the vertical total to be set in the adjust line in case we come across a 6845 that doesn't add the extra line (may also make HW match SW).

Re: Video Timing

Sorry, I was half asleep when I wrote that, assuming you have many "screens" per field, you would get many blank bits, not what you want.
Unless you are going in and out of mode 7, the vertical timing doesn't change, so apart from one long/short row, the timing shouldn't be too far off.

I prefer Microsoft mice and have only broken on since the 90s. I replaced the micro-switch and it's good as new.

Re: Video Timing

Would it be "safer" to add a total adjust (R5) of 8 scan lines and then change your mode in that section, with 38 rows and vsync one row earlier? If I understand what you are doing, and I might have missed it, this would make everything match as well as supporting any 6845s that don't add the extra ...

Re: US BBC micro restoration - help (and PSU) needed

Some of the ULA models have inverted output compared to another, but I don't know which are which. I believe the mod is to flip the invert signal coming in, but I could be completely wrong about all of this. I think my"debug OS" room image would still work, but I don't know how the RF and composite ...

Mostly it is a case of rearranging things into pages, unrolling and using one register for source or and the other for dest. The 6845 can also be "fun".

You could use CMP #&C0 and BCS on a B if you don't need the carry. If you do, you could BIT zp where the address has &40 in it.

Every time I start a new session on stardot on my phone, I get a warning about invalid site certificates.

Welcome, that was a great place to start. I love 6502, it is so straight forward, and write rewarding when you thought you didn't have enough registers and then find a way to get it working.
