British Telecommunications Engineering Volume 6 Part 4 page 285 First STEbus Modem British Telecom Microprocessor Systems has launched the first STEbus-compatible modem which provides systems designers with an easy means of building remote STEbus control...
NOTE: This post contains sponsored content. I finished rev 1 of a 5 slot backplane and sent it to PCBWay who were kind enough to send me some free boards to try out in exchange for a review of the service. Check out the end of this post for...
Here are the STEbus and VMEbus boards I am aware of. I have some of them, and some documentation. Let me know which ones interest you. Code Name Title (Main features) [notes]J004 ARC8000 VMEbus Z8000J020 SC88 80188 (80188 and dynamic RAM)J023 SCPUA...
British Telecommunications Engineering Volume 7 page 77 All-CMOS High-Temperature STEbus The first all-CMOS processor board for the STEbus has been announced by British Telecom Microprocessor Systems. Based on Intel’s 8031 CPU with CMOS memory and input/output...
First, the cons, which are deal-breakers for me.1. 20 Address Bits. This might seem like an awful lot of address space; I mean, you have 1MiB of memory space with STEbus. However, with so few address bits, this means you cannot practically...
SEMC The SEMC and SEMC-10 use an intelligent LSI chip set which provides all the functions required to drive a servo motor without interaction from the host computer. It has inputs for an encoder and resolver, and produces a control voltage and pulse...
The SC180 is a low-cost Z180 board for general-purpose use in STEbus systems. It has enough memory to run CP/M Plus. It has two counter/timers, two serial ports, two DMA units, a memory-management unit and an interrupt controller. The SC180 will act...
The STEbus specification allows up to 4 amps per board on the 5V rail.A fully-populated STEbus backplane with 21 boards could thus take up to 84 amps.The Arcom backplanes had many M4 threaded power terminals for attaching heavy-duty power cables.Although...
British Telecommunications Engineering Volume 6 Part 4 page 284 Intelligent Serial Input/Output Module for STEbus An intelligent serial input/output (I/O) card — the first for the STEbus — is now available from British Telecom Microprocessor Systems....
2022-02-19Spotted one for $220. Bought it. Works out to be $327.22 or £240.77 after import duty and postage. Not cheap but STEbus evangelism is my bag. Due to arrive in March, when I shall read its programmables!
STEbus Colour Graphics and Text SGT1 The SGT1 brings high-resolution colour graphics to the STEbus. Graphics and text can be mixed on the screen, and the on-board 6803 processor with 64 kbytes of RAM and a 6845 CRTC deals with graphics generation and...
The STEbus writes output port bytes to an edge-triggered latch, and reads input port through an 8-bit buffer. The STEbus writes command bytes to an edge-triggered latch.The microcontroller writes response bytes an edge-triggered latch.The actions set...
I originally had the idea of making a Z180 to Z80 adaptor and then plugging the Z80 side into an STEbus Z80 board. Really inelegant and I suspect it would have added unreliability even if the idea was sound.
My STEbus rack already has a 3.5" floppy drive, and spare power connectors for hard drives.Amazingly, I found I still had a set of 3.5" floppies with MSDOS 5 and Windows for Workgroups v 3.11 so that's a start. I have a 3.5" floppy drive and a spare...
