Finding common GND
Alright, there is some progress on the front of my 68040 to 68060 adapters. In the last month I have made a serious improvement of my lab: a simul focal microscope with double boom stand. This has vastly improved my ability to see what I am actually soldering, instead of almost flying blind. This led […]
iKod.se int7 adapter
Don’t you know the feeling when you’re just on cloud 7 with your Amiga? Maybe you remember the action replay for Amiga 500 which let you scan memory for lives and mods? Or you miss a nice and handy debugger when debugging that latest 68000 assembly of yours? ikod.se had the right solution for your […]
68040 to 68060 – Upformation
Back in the late 80s and early 90s, when the Amiga was relevant as a technical revolution, I was never able to lay my hands on anything beyond an 68000 with 7.14MHz. Years later, around 1997, I acquired an Amiga 3000 with 25MHz as part of one of my university side gigs of porting software […]
Cyber, Cyber!
Or was it “Hyper, hyper!“? Scooter, please help a child of the 80s and 90s out here! This episode is about shuffling hardware, and what it takes to make your Amiga really fast! I was lucky enough to get my hands on a Cyberstorm MK2 card (and I still have all my organs). I almost […]
Das Labor
Ok. I have to make a confession. I’m really awful at keeping organized. And if I let my inner engineer engineer out for an evening or two, it can get pretty messy and it starts looking like my cat Katze’s bed, a wonderfully cozy place full of toys and no space to be: Alright, I […]
¡Una hija para mi Amiga!
The heat wave has hit Mountain View these last few days and caused a power outage for the better part of the weekend, so between 40C/105F and no electricity to power a soldering iron we enjoyed mango ice instead of working on all the projects. None the less, after laborious project cat Katze (カツ) dropped […]
The first cut is the deepest!
A few days ago I did some temperature measurements with my zz9000 graphics card from MNT GmbH in Germany, which turned out to be surprisingly hot. It started out as a test of the CPU temperature of my freshly overclocked MC68060RC50 (rev6) running at 100MHz, when I noticed that the graphics card seemed to run […]
Fake flash!
I’ve heard of the whole Chinese relabeling industry, but in the past I have always been lucky with my eBay purchases. Until this last time. I kept ordering a number of times from the same folks on eBay, but it seems that they ran out of genuine AMD 27C400-120s and decided to ship relabeled Toshiba […]
A tale of two diodes…
What happens to long lived electrical engineers? They diode! I have had trouble with the Amiga 4000’s serial port since I got the machine. At first I got a few bytes through every now and then, but it was pretty much unusable, even at 9600 bps. When “learning online” about all the magic of open […]
Keyboard fun!
My keyboard is missing a key. There’s no escape! Well actually it wasn’t escape that was broken on my nice click-a-dee-clack Amiga 4000 keyboard, but CAPS LOCK! And bit even the key itself, it was the LED that just wouldn’t show the status. No problem, let’s take it apart At first I thought the LED […]
