Example of replacing exhausted Electrolytic Capacitors.
My advice is always to replace all capacitors although at first view does not seem exhausted with acid leakage.

I thank my dear friend that gave me the Spem EXP-MEM 512k.
Autopsy:
Various companies offered to upgrade your QL with an internal memory upgrade. This was normally 512K, but some companies also offered a 256K version.
The method of upgrade was in two ways:
- Removal of the existing QL memory chips and replacement to give a total of 512K
- An internal board, which connects to the 8301 ULA socket, and has a wire to the 68008 processor.
The downside of this method of upgrading the QL’s memory was:
- The memory access was slower than external memory
- You could not use some of the later QL expansions, such as the Trump Card which themselves had memory built into the interface.
Internal interfaces were advertised by a range of companies, including CST, MicroPeripherals and Silicon Express.

Forth, the Language.
Forth is a different language. It’s aged and a little weird.
What’s cool about it? It’s a very low-level and minimal language without any automatic memory management. At the same time, it easily scales to become a very high-level and domain-specific language, much like Lisp. Compared to C64 Basic, Forth is more attractive in almost every way.
It is a lot more fast, memory effective and powerful. Compared to C, specifically cc65, the story is a little different. It’s hard to make a fair comparison. Theoretically Forth code can be very memory efficient, and it’s possible to make Forth code that is leaner than C code. But it is also true that cc65 code is generally much faster than Forth code.

I thank my dear friend that gave me the Staff K8AP Multi-Compatible Keyboard. Unfortunately is missing the adapter card to install inside the computer.
Autopsy:
Compatible keyboard for the Apple II / IIe.
I thank my dear friend that gave me the Atari Touch Tablet.
Autopsy:
The Atari Touch Tablet was a well designed and brilliant idea. Giving the user the ability to use a virtual sheet of paper and pen, they could draw, drag and drop, paint and erase images with the included Atari Artist program.
Perhaps given more time, the Touch Tablet could have been used for many other innovative ideas and perhaps vertical market applications. The Atari CX-77 Touch Tablet was designed by Tom Palecki formerly of Atari’s Industrial Design group.

The Mivar 9BN2V it’s a 9 inches B/W CRT screen with 16 programs preselection with a electronic tuning for each program. It can be powered even with a 12volt and has a headphone jack.
Mivar is an Italian TV-set manufacturer. It was founded by entrepreneur Carlo Vichi in 1945 in Milan. Mivar used to produce radios and CRT televisions, but now produces only LCD LED televisions. Mivar is the last Italian factory of televisions. Their factory is in Abbiategrasso (20 km from Milan).
Since the 80s until 2000 in Italy Mivar TVs have had a very wide spread, in fact these televisions were present in almost every Italian house, in the Italian TV Studios, in schools, hospitals, hotels and prisons, because these CRT TVs were good, cheap, robust and durable.
When the market decided to focus on the LCD TVs, Mivar was unprepared and had serious difficulties. But thanks to the tenacity of the master Carlo Vichi, Mivar introduced in 2010 some new attractive and competitive LCD-CCFL TVs, and in 2011 some new LCD-LED TVs. The televisions made today by Mivar are also particularly simple and rational, with a particular Italian design and front speakers for better sound. Today’s Mivar TVs are all made in Italy.
