Here ... have a downvote

I can’t disagree 😂

You should consider one of those Nakamichi Dragon cassette decks. They are mechanically fascinating and supposedly sound fantastic

What’s the tariff on Australia? If it is higher, I suggest they simply put Heard and Macdonald as country of origin. Dumb won’t notice

Adrian for President

I have the exact same reaser, and the timer was already defective when I got it. Never missed it though.

Surely this can be resolved with a bend paper clip toucing an edge connector at the back of someting

A repair I do over and over again and seriously dislike is trying to fix my chip puller. Dang, that’s annoying when it goes apart

Datasette repair notes - Commodore’s datasettes are relatively robust, and many of the common problems can be fixed easily. This post contains my datasette repair notes, and will be updated regularly. Tools Testing and repair...

How to fix the most common errors in a commodore 1530 datasette:

Retro repairs going meta: Spending more time repairing the gear used to do retro repairs, than you spend on doing retro repairs.

Indeed an unusual repair job on a C16. Compared to the C64, the average C16 repair must be 1/10 of the time due to all the major ICs being socketed and the CPU accouting for 90% of the errors.

How do you change a drive belt in a 1530 datasette? I have written a new blog post www.retrotrade.dk/2025/03/17/r...

YouTube video by Happy Little Diodes Can you get 80K out of your 48K ZX Spectrum with just one extra chip??

I just need to share this video for the very thorough explanation on how RAM worked in the early home computers:

When I buy a lot from a smoker, I use magic erasers to remove the smell.

It happens all the time, bro.

I got one of these this very weekend. I have been using a HANTEK HE6022 for a year or so due to lack of space on my desk. The hazzle of getting it connectd to the laptop made me consider this option instead.

Have you come across any serious limitations and did you update the firmware?

And @factorofmatt.bsky.social, a suggestion for your roadmap: What about doing a new diag cart which provides more detail on th failed tests that the original? n/n

One of the issues with the trouble shooting carts is that you don't know exactly what the tests do, and how to interpret the results. Having the opportunity to link symptoms with parts would take it way further. 2/n

@factorofmatt.bsky.social @janbeta.net @adriansdigitalbasement.com Would it make sense to make a "pictorial fault guide" with DeadTest/Diagnostics/DesTestMax inserted, i.e. where you link observed behavior to specific parts? (1/n)

I can recommend doing some 1541 repair videos. 1541s are quite interesting to work on as they are quite versatile compared to the c64 itself

I suppose this has something to do with using the DesTestmax in SL mode. Are you planning a video to demonstrate this feature? Would be interesting

I got the mechboard from them too and have to admit that I'm not overly impressed by the quality. The asssembly instructions are non existent despite were much needed. I haven't been able to mount the Return key the intended way.

You should do more 1541 /1541-II repairs. They are interesting to work on, and there are som many new problems to discover there. While the c64 seems to be conquered wilderness, the 1541 remains more upstream amazonian.

You mention that the 555 is your favourite chip. COuld you put some words on what makes it so special?

Your openness is much appreciated

Metal shielding and perhaps a 250425 board

They surely aren't meant for typing, as the case feels relatively soft. But all case variants had their flaws. The breadbins tend to crack in thetop left corner just above the 1-key.

They are rarer for sure, but the rarest C64C case is without doubt the case where the badge is replaced by a beveled logo molded into the plastic

I have an interesting 250407-board with no V-sync signal despite a working VIC-II. I have seen it occassionaly on boards that had an 8701 (and a dead one). I have only seen it twice on earlier boards, including on a KU-board. I am wondering whether this perhaps could be the modulator.

Er det ikke snarere et udtryk for manglende selvværd når alt kommer til alt? De fleste mænd ved vel godt, at ligegyldigt om den er stor eller lille, så bliver den hverken større eller mindre af at blive vist frem.
