IBM 650 Tube

This is a tube from a very old IBM 650
The IBM 650 was together with die 700/7000er Series the first generation of mainframes


SMS-Card from IBM 7030

This is a SMS-Card (standard modular system) from a IBM 7030
SMS-Cards used from 1959 to 1964 for second-generation mainframes IBM 7000, IBM 1400 and IBM 1620
Card-Number is ERK 374494


SLT-Card from IBM/360

This is a SLT-Card (Solid Logic Technology) from a IBM/360
SLT-Cards used from 1964 to 1970 for the IBM/360-System


IBM/360 magnetic core memory

This is a magnetic core memory from a IBM/360
This module is a part from a 9-module-block
Every module of this blocks holds 16.000 Bits


IBM/370 MST-Card

This is a MST-Card (Monolithic System Technology) from a IBM/370
MST-Cards used from 1970 to 1975 for the IBM/370-System
Each MST chip holds about 5 circuits and is the approx equivalent of an SLT card.

IBM 3705-Panel

This is a old Panel from a IBM 3705-Communication-Controller for IBM/360- and IBM/370-Systems
Its purpose is to connect communication lines to the mainframe channel,
connection of Systems Network Architecture (SNA) devices to a mainframe.
Operationsystem ACF/NCP Version 3
maximu RAM 512KB
The 3705 was replaced by the 3720 and 3725. The 3745 was similar but not entirely compatible


IBM Punch Card Reader/Checker

Manually Reader/Checker for IBM 80-column punched cards


IBM Bus/Tag-Cable

Short IBM Bus/Tag-Cable. Late version from IBM ES/9000
The parallel channel is one of the oldest interfaces to a mainframe. It was introduced to the mainframe in the 1960s. The parallel channel (also called an S/370 I/O interface) uses two cables called bus and tag.
