I got hold of a Pegasos 2 motherboard today. The Pegasos motherboard originally ran MorphOS (and some Un*x OS), for Amiga enthusiasts, MorphOS was off course the reason to get one. (more…)

I guess broken SIMM sockets in the A4000 is no news for most Amiga enthusiasts these days. You rather expect a second hand Amiga 4000 to have broken SIMM sockets than not.

The kind of SIMM sockets used in the Amiga 4000 is all plastic, the little tabs holding the SIMM secure has a bad habit of breaking off, meaning the 72-pin memory SIMM is only held down with one tab or in my case, with no tab at all since both where broken off.

The previous owner of this A4000 motherboard had come up with a genius solution of making a cardboard lasagne above the 72-pin memory and below the lowest Zorro card, a solution that -incredibly- worked stable but did not look so good.

I messed around my Phase 5 CyberStormPPC card today. The card holds a 68040 clocked at 25 MHz and a 604+ PPC clocked at 180 MHz.

The CyberStormPPC card is really the pinnacle of classic Amiga performance technology. You get a card capable of running a 060 CPU and you get a powerful co-processor (the PPC chip) capable of doing things much faster than the 68k CPU ever could. So why not ditch the 68k chip then?

Today I picked up a used Amiga 4000 desktop packed with some goodies such as CyberStorm PPC 040, 180 MHz PPC, SunRize AD516 16-bit soundcard and a couple of other bits.

The A4000D is one of my favourite Amiga computers because of its relatively small size, expansion potential and good looks, they where also very popular, at least here in Sweden..
