Re: Questions about "scheme types"

1) The downloads table has a column schemetype_id, which can be NULL. There are also schemetypes with text "None" and "Undetermined". I assume "None" means explicit there is no scheme, which makes sense, but "Undetermined" seems to mean the same as NULL to me...

Re: Build your own handheld ZX Spectrum with Raspberry Pi Pico

It's awesome! With a better (i.e. solid) case, it'll be even better! Do I see a portable "Next"? ;)

Re: scrconv - SCR -> GIF/PNG/JPG converter

Notes on the auto-border colour feature: The detection is pretty simple: it just counts the total number of PAPER and INK colours and chooses the most common one. I experimented with 30 or so screens and the result is that most will still have a black border. Of those that don't these are the more ...

Re: RAM chips for lower ram, can these be used?

35th week (end of August) of 2000?
Seems more legit, but lots of rust on the middle legs... no idea if it'll work or not...
or if it's the same chip inside as it states outside.
All of them bear the same labeling?

A standalone DRAM tester would be ideal to see if it behaves as expected or not.

Re: Odd Kempston Interface 'Plus'

The Z80 always reads an eight bit byte. A Kempston joystick interface uses bits 0 to 5 for the four directions and fire. That leaves three inputs ‘spare’. Hence if this particular interface uses an eight gate tristate buffer chip, it’s possible to add three extra inputs… Mark And then add a "S...

Re: why have some of these loaders been partially/not resloved?

Well, that list is really old, ported from Andy's old site, and in need of a review to be up-to-date.
I guess the schemes are on the 2nd or 3rd tables when the saving routine couldn't be found.
