This is the SoftROM for the PET. I will be using it as an 8K RAM expansion on the PET, instead of a flexible option ROM. It is mapped to $9000-AFFF.

I will be using the 6264 8K SRAM chip. What will I use it for? Well, I will be asking BitShifter to modify his awesome PET interpreter to use this 8K as a cache. The 32K of RAM on the PET forces the interpreter to load quite often from disk. An extra 8K will be very welcome to avoid too many loads.

The SoftROM maps to $9000-$AFFF as written before. This means it is supposed to go into D3 (SoftROM) and D4 (only the chip select line, pin 20). Question is: Which socket are D3 and D4? Commodore didn't put any silkscreen on the board... I THINK it is the two rightmost empty sockets.

My second Amiga 1200. What an absolute beauty! This is an Escom version (made in France), released after Commodore's bankruptcy in 1994. I'm very happy to add this gem to the collection 😍

@lukhash beautiful. How is the RTC battery doing inside there?
Would love to have an AGA machine myself. But I am also very happy with my OCS A500.

Murder on the Mississippi:

„The German Version
In 1986 then video game journalist Boris Schneiderundertook one of the first documented fan translation efforts:
Over the course of one weekend (!) he single-handedly cracked and translated the C64 version of Murder on the Mississippi into German by using a simple hex editor and a self-written disk editor. He then sent "his" translated version of the game to Activision, which they officially released in Germany.“

@futurewas8bit Will you ever be selling the deluxe Atari A/V mod again?

I would have use for at least one... got an unmodded console here.

My childhood trauma was watching "The Tripods" on German TV (ZDF) and not getting a third season! About 15 years later I finally read the books and could get some closure. And now I have the DVDs! Did you watch this series back then? What did you think about it?

root42,
@root42@chaos.social avatar

@daputz @kurth I watched it with the German dub, obviously, being a primary school kid, and I will rewatch it in the same context. I'll take it as it is: a mid 80s BBC production. This, ALF and TNG defined my first couple of years at school. :)

@dec_hl No, it doesn't exist! The BBC canceled the show!

So the batteries in my ran empty. This was the opportunity to ditch Tristam Island for now. The inventory mechanics were a little too annoying for me. So… how about a classic? Bronze by Emily Short. It is slow as molasses, because it’s written in Inform7, but still works fine. Even got the compass rose in the upper right corner!

@phranck Das Buch war das einzige was ich seinerzeit bei Audible zurückgegeben habe. Den Hauptcharakter fand ich furchtbar. Ich frage mich ob die Serie anders ist.

@emanuel OCS! But I think they do a palette switch for the interface area, to get more colors on screen.

I decided to work on something a bit lighter (literally) and fun today and refurbished a 1975 scientific calculator made by . It still works (except for the rechargeable battery which thankfully was removed by the previous owner before it could do any harm)!

@janbeta Are those the little bubble LED modules, that HP also used a lot in their equipment?

In my abundant free time, I want to make a phone app optimized for taking photo or video of CRTs, with quick access to shutter speeds of 1/25, 1/29.97, 1/30, 1/50, 1/59.94, and 1/60 of a second. I've tried so many camera apps with manual settings and each one has annoyances or too many settings.

@root42@chaos.social avatar

@polpo great idea! Plus maybe video mode..? Plus a 15kHz audio filter. :)

@root42@chaos.social avatar

@fozztexx @polpo this will explode feature wise. :) But I guess more features can be added over time…

@eazy 2.4 oder 5 GHz? 2.4 ist besser für draußen, da deutlich höhere Reichweite.

After getting the #Commodore #C64 and #C128 running again, the next device to repair is the #C1571.
It had #corrosion and #rust on the main board and the power supply is beyond repairworthiness. I'd replace the latter with a #meanwell RD-35 with 5 and 12 volt output.
One #diode was rusty, a few traces needed #cleaning and five #resistor looked bad. Hope the black hybrid chip is still okay.
Sadly, the lower read head seems to be broken, my work might've been in vain.
#floppydrive #retrocomputer

the worst corrosion on the main board. a rusty diode and a few other rusty pins.
the same section after cleaning and replacing the diode and five resistors (the blue ones). the fixed traces have been covered by soldermask again
the mechanics schowing the read heads. sadly, the lower head is reading open circuit where it shouldn't, indicating broken coils.

@rommudoh does a regular format using OPEN and N0:… work?
