About 3 months ago i have repaired my Tatung Einstein with stability problems, after a few minutes the screen was filled with random characters. Below the replacement parts:
On the same day has broken the Tatung TC-01 Monitor, the vertical sync is died without any way of adjustment. Yesterday, instead of celebrating Easter, i have tried to repair the monitor, the faulty component was as follows:
Very happy i have connected the Tatung Einstein to the monitor, i have tried a few games and after 15 minutes the Tatung (computer) decided to die. I spent more hours to understand what could have happened, oh! found it, some ram burned. Below the replacement parts:
What could happen again?
I also did the dump of the eprom (rom), the download below.

from Wikipedia:
The Epson HX-20 (also known as the HC-20) is generally regarded as the first laptop computer, announced in November 1981, although first sold widely in 1983. Hailed by BusinessWeek magazine as the “fourth revolution in personal computing”, it is generally considered both the first notebook and handheld computer.
With about the footprint of an A4 size page, the Epson HX-20 features a full-transit keyboard, rechargeable nickel-cadmium batteries, a built-in 120 × 32-pixel LCD (smaller than that on many mobile phones today) which allowed 4 lines of 20 characters, a calculator-size dot-matrix printer, the EPSON BASIC programming language, two Hitachi 6301 CPUs at 614 kHz which is essentially a souped up Motorola 6801, 16 kB RAM expandable to 32 kB, two RS-232 ports at a maximum of 4800 bits/s for the first 8-pin DIN connector intended for modem or serial printer with the second port capable of 38400 bits/s using a 5-pin DIN connector which was mainly for use with external floppy drive and video display an early concept of docking station, a 300 bit/s acoustic coupler was available, built-in microcassette drive, barcode reader connector.
Uses a proprietary operating system, which consists of the EPSON BASIC interpreter and a system monitor program, and weighs approximately 1.6 kg. Known colours of the machine are silver and cream, while some prototypes were dark grey. The HX-20 was supplied with a grey or brown carry case. An external acoustic coupler, the CX-20, was available for the HX-20, as was an external floppy disk drive, the TF-20, and an external speech synthesis Augmentative Communication Device (ACD), ‘RealVoice’. Another extension was the serially connected 40 x 24 character video. It used a special protocol, EPSP, which was also used by the external floppy disk drive.
The battery life of the HX-20 was approximately 50 hours running BASIC and less using the microcassette, printer or RS-232. The data integrity could be preserved in the 4.0 – 6.0 V range. The power supply was rated for 8 W. Operating and charging it would tolerate 5 – 35 °C. Data integrity could be preserved at -5 – 40 °C. The HX-20 could be stored between -20 – 60 °C. The later, more popular TRS-80 Model 100 line, designed by Kyocera, owed much to the design of the HX-20.

SNDH archive v4.1 released – 3726 SNDH files (total 7003 tunes)
Ever since the birth of the Atari ST, different chip music formats have had different ways to use them. If you are coding a chip music player for the Atari ST you would have to use dozens and dozens of special ways to replay music.
But in the mid 90′s, BDC of Aura crew became tired of this inelegant system and decided to fix the issue once and for all. He then created the ‘SNDH’ file format. SNDH is actually the original songfile and replaycode with a header bolted on top of the music and replayer. The header has a unified calling interface no matter what type of chip music is hidden beneath it, and it has extended datas about the music.

I had several problems with the repair of the Hewlett-Packard HP-85.
The first problem was the way to reconstruct the pinch roller using a latex tube, this is a very bad choice, then i have used a 10mm heat shrink, this choice instead is very good.
The second problem was the rubber parts of the pinch roller are literally dissolved and the rubber is went to cover the optical diode and part of the pcb and of course nothing has worked and the tape drive was always in stalled state.
After cleaning, the drive started to work perfectly. The last problem are the magnetic tapes 3M DC-1000 instead of HP DC-100, for the correct operation you must perform a modification by adding a resistor of 2kohm in parallel to the already present on the pcb. After this mod you need to format the tape with the “erasetape” command.
I must also thank John of the site vintagecomputers.freeserve.co.uk for the support.
