VELA - Light gates

The VELA was able to use pulse triggering to allow for the timing of events between two triggers. One typical example of this was to use light gates to measure the speed of a toy car or other object as it passed between two fixed points.

If you've come across this page because you've found a dusty old VELA or any of the peripherals I've mentioned on the site in the store cupboard of the science department and you're wondering what you can do with it... You could always consider donating it to a good home such as mine where it would be reunited with a BBC Micro, archived for the future and used!

Although I now have many VELA related items, I am still missing many more bits and pieces so if you happen to have a VELA, any VELA software, manuals or related VELA handbooks, then I'd still be very interested in hearing from you so please do get in touch!

Of particular interest are any VELA SAM4 compatible modules and software for the RM380Z, Apple II and IBM-PC's of the day which currently are lost to the mists of time with the prospects of viable floppy discs containing the software being more remote as the years go by.

For a full list of VELA related items I'm looking for, please check out my VELA - WANTED, DEAD or ALIVE! page.

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.
