Ping to @alexfree at this point. You might ask yourself why: While this is mostly about a camera, there is something on the bottom of this entry regarding PS1 (below all pictures).
People to ping as well for the main topic (since blogs go unnoticed otherwise)
@IC_ who seemingly shares my interest for old electronics
@SylverReZ who seemingly shares my interest for optical discs/drives
@Alexander1970 and @Blauhasenpopo because I would have shown them this in PM anyway →
and finally @Nikokaro to show him I bought additional old junk. →
Got a new old digital camera: Sony Mavica MVC-CD200
In my search for old CD-R with a slightly different ATIP spatial period (≈64µm instead of ≈54µm) I stumbled upon this nice series of old cameras. Strangely I've never heard of this before – only of digital cameras saving images to floppy disk (which is anything but practical). Now, a CD-R is a different topic. It does have enough memory capacity to store some acceptable pictures compared to a classic floppy disk.
I had luck getting one camera from that line – albeit the smallest, weakest model (surprise, surprise) featuring only 2 megapixel pictures… but better than getting none at all.
Pictures of the camera:
The battery is shot – not unexpected for a 20 year old li-ion and picture quality isn't what you would expect nowadays. But it is kind of fun to play with the camera. Three random pictures taken with the MVC-CD200. Those were written on a cheap CD-R; A type which is available new and in arbitrary numbers right now. This gave a "Mavica CD recommended" message, but other than that the modern CD-R got accepted and works.

My new camera is working fine. It came with two original Mavica CD-RW with only 156MB of memory capacity. That is exactly what one would expect with old standard track pitch but longer spatial period in ATIP:
Still expecting the delivery of two packs of Mavica CD-R, not CD-RW.
They were expensive, but not as ridiculously expensive as the 12cm discs I found on eBay, the ones I actually wanted to have. That brings us to the PlayStation 1. It would be nice to have some kind of test software. A homebrew application doing some read tests: Sequential reads as well as some random seeks to measure if full speed (2x CLV) can be achieved with a disc and how the seek times are affected by various factors (track pitch old 74min vs . current 80min CD-R) and the bigger pits caused by special ATIP.
The CD-R will not arrive this week, but when they do I would be willing to sacrifice a few of them for testing and to write Tonyhax International boot disc – but the supply is not abundant, so this needs consideration.
