Dynavox CS-PA1 (MK 1 Modell) Kleiner Verstärker mit 3x Cinch Stereo Eingängen, 1x Cinch Stereo Ausgang und 2x Lautsprecheranschlüsse. Vorderseite: Bass, Treble, Kopfhöreranschluss. Echter On/Off Schalter, Betriebsanzeige mit LED. Auswahlschalter für die drei Eingänge. Der Volume Regler in meinen Bildern ist nicht Original. Ich habe ein gebrauchtes Gerät erstanden, bei dem der Volume-Regler im leiseren Bereich deutlich kratzte. Daher habe ich den Regler durch einen anderen ersetzt, der zufällig in meiner Grabbelkiste herumflog.

Inmac clear signal tristate tester Tester for serial line connections. There are several devices from Inmac, this is the 8363-1 with internal battery suppy (9 volts battery). Other models are “passive” and have no own power supply. Allows to test 1:1 and cross cables via dip switch. 1:1 means pin 2 is connected to pin 2 and pin 3 connected to pin 3. cross cable means 2 is connected to 3 and 3 connected to 2.

Transistortester und andere kleine Messutensilien Ich stelle hier ein paar kleinere Messgerät vor, die ganz nützlich sind. Grundig Semitest 1 Test von NPN/PNP Transistoren sowie Dioden. Gerät ist geschätzt aus 70er oder 80er Jahre. Sehr stabil gebaut, mit interner AA Batterie. Basisstrom 10 µA oder 100 µA. Verschiedene eingebaute Sockel, u.a. TO-3. Anzeige des Kollektorstroms mit Meßinstrument 0..6mA. Transistor tester M328 Kleiner Bauelemente-Tester mit ATMega328 Mikroprozessor und 128x140 1.8 Zoll Farb TFT Display.

Amstrad NC-100 and Amstrad NC-200 laptops with Z80 CPU Both computers come from around 1992 SRAM cards Cards to search for: PCMCIA Type 1 SRAM Card , <= 1MB. (It is rumored that 2 MB cards can be used but only first 1MB is usable then, I have not tested that). These cards contain SRAM chips and a battery for keeping RAM content over some time (about 1 year). The card shown below uses a 3 volts lithium battery type DL2325, but this varies from card to card.

Hakko 475 Desoldering Station Hakko is a company with japanese origin. They are famous in the area of soldering tools. Also desoldering tools. Why Hakko was a choice? I already own a Hakko FX-888D soldering station. This is a low-cost product from Hakko, but it offers many advantages, compared to the soldering irons I had in the past. One very important thing is the time after being switched on, until the iron is usable.

Für Freunde des guten Klangs, insbesondere bei Plattenspielern, ist Dual ein Begriff. Wie ich in Foren gelesen habe, sind die alten Dual Plattenspieler einem Neugerät normalerweise an Qualität überlegen, bis zu einer Neugerätmarke von rund 500 Euro. Erst dann bekommt man was Besseres. Ich persönlich würde daher immer einen Dual, oft für ein paar dutzend Euros, nehmen. Und tatsächlich sind diese circa 50 Jahre alten Geräte heute oft noch in sehr gutem Zustand, mechanisch robust, elektrisch dauerhaft hergestellt.

Ultrix 4.5 on a MicroVAX 3100 I wanted to install Ultrix on my VAX, described here. Here is some log regarding installation. The installation was already documented by various people, so it is nothing new, and credits go to these people. Ultrix version used is from 1995, so 28 years old. The following screenshot shows, after installation, some DEC Windows tools, remote displayed on my Linux machine. You see 2xdtterm, dxpaint, dxpuzzle, dxnotepad and dxclock.

SCSI2SD SCSI2SD is an approach emulating SCSI hardware with software running in an PSoC microcontroller from Cypress. An ARM Cortex M3 controller is provided as part of the PSoC, and furthermore a bunch of programmable system parts, e.g. usable for interfaces etc. Focus is on mass storage, so SCSI2SD can emulate hard drives and other mass storage devices, all on a SD card. Main website is http://www.codesrc.com/mediawiki/index.php/SCSI2SD . Alternative PCB layout, specialized for Powerbook hardware, but can be used for general SCSI purposes too: https://www.

Digital DEC MicroVAX 3100 I bought this as a fully working machine. Series BA42A board and KA41A CPU. So this is a Microvax 3100-10. 16MB RAM. The machine contains two harddrives. One contains a VMS operating system, the other one a NetBSD installation. So it can run both VMS and UNIX. Contains a DHW-42-AA (also called: DSH32-B?) extension board. It offers 8 additional serial lines (for terminals) and 2 synchronous lines RS-423.

DEC VT 330+ is a successor of VT330. My device has latest date codes from week 28 in 1990, so it is about 1990 or 1991. The electronics differs from the VT330, the digital logic part is build on a single PCB only. While older VT330 were built on two boards. This newer board has an Intel 8032 8-Bit CPU, 2x128 KByte EPROMS (27C010), 2xHM62256 2x32KByte RAM. The microcontroller has two companion chips SCC2692AC1N40, these are dual asynchronous receiver/transmitters.
