The es65 Microcomputer
A somewhat exotic computer from 1980 which holds the title of Least Documented Computer On The Internet (according to me).
​
Made in Vienna, Austria by Ernst Steiner, this is a multi-user 6502 system. It boots up from a ROM board, and every user is assigned a memory board full of 2016 RAM chips to work on. It is representative for a whole class of custom-designed computers from the late 70s: no standards, sophisticated users knew how to make the things useful. My es65 has the luxury of a dual floppy disk drive so the users can actually save their work.

Unfortunately, I have no documentation at all - if you have any information, please let me know. I'll add whatever I find on this page as my search proceeds... ​

Anecdotal/Background
Konstruiert wurde das System von einem Lehrer in der HTL St. Pölten (eine Ingenierschule), die Fa. Ernst Steiner (Wien, heute Personalberatung) hat es dann vermarktet.
​Soweit ich mich erinnern kann, war das Betriebssystem auf einer (E)PROM-Platine, auf den Diskettenlaufwerken waren nur die Arbeitsdaten (Source-Code, Assembler-Code, List-File, etc.). Für jeden User gabe es eine RAM-Platine voller 2016 und es gab noch ein Testsytem TSYS: ein zweites einfacheres System auf einer langen Platine mit Daumenradschalter, Siebensegmentanzeigen sowie 8 LEDs und 8 Taster. Man konnte dann den Maschinencode downloaden und sofort testen. Betrieben wurde das System mit HEATHKIT-Terminals über RS232.
