WANTED, DEAD OR ALIVE!

It's rather dramatic I know but all the same, working or not, I'm always on the lookout for more VELA equipment to document, archive, use and learn about.

Having much of the documentation, I've been able to arrive at quite a long list of items that I'm missing and where possible, I've found pictures of them.

So if you can help me in locating some of the items below, I'd be most grateful.

Missing VELA Hardware

The VELA truly lived up to the "Versatile" part of its name. Not only was the VELA an extremely flexible data logging tool, it could also be used as the basis for a sense and control system and even as a teaching system for basic electronics and binary logic. These extra devices connected to the VELA using its digital I/O connector.

  • Vela Buffer Board (order no. 1030)
    Buffer board
  • Vela Logic Tutor Board (order no. 1031)
    Logic Tutor board
  • Vela ROM Extension Board (order no. 1032)
  • Light Gate (order no. 1035) - found November 2016

Missing Sensor Adaptor Modules

Sensor adaptor modules provided a way to connect standardised sensor modules to the VELA in a mix and match fashion providing great flexibility in the monitoring applications the VELA could be used for. With the addition of the SAM ROM for the VELA, the sensor data could be displayed by the VELA in the correct units without any extra conversion process being required.

Missing Software

Educational Electronics published and sold several software titles for four different hardware platforms. Software for the BBC Micro appears to be the most common and all of the archived titles are for the BBC Micro platform. Sadly, there is still a large amount of software that is missing from the archive and they are listed below by platform.

Other VELA Software

The VELA manuals contain software listings for the transfer of data to several computers, the link below contains an SSD disc image containing the source for the BBC Micro transfer code.

ROMs

The following ROM images are Mk I EPROMS and are incompatible with the ISL1* ROM from the VELA Mk II.  You can use the Mk I ROMs in a VELA Mk II or VELA PLUS but there are several differences in the data formats they produce when exporting from the VELA so when sending data to a microcomputer, it should be told it is connected to a Mk I VELA.

The following ROM images are for the VELA Mk II as indicated by a red *.

The following ROM images are for the VELA PLUS as indicated by a green *.

The following ROM image is for the SAM4 Sensor Adaptor Module

  • SAM* ROM

This final ROM is the RS Components ROM image that replaces ISL1* for their re-branded Multi-function Intelligent Data Logger.

IC Datasheets

The following datasheets cover all of the IC chips that are used in the VELA Mk. II data logger.
