VelaXFER is data analysis software for the BBC Micro and VELA that I've written in order that people can use their VELA if they don't have the original software. It's an early release as yet but has many useful features and is compatible with the BBC Micro*, BBC Master and Acorn Archimedes** range of computers.
* The BBC Micro requires a 6502 second processor to run VelaXFER
** The data transfer routines are currently only compatible with the BBC Micro and BBC Master series of machines.
VELAnalysis 1.3 was a commercial piece of software for the VELA released by Educational Electronics Ltd for the BBC Micro. The original version lacks some of the features of later versions such as improved zoom facilities, smoothing algorithms and it only supports the loading of two 1KB data blocks which means that the fastest data logging settings on the VELA which create a 4KB block of data aren't directly supported without the data being split into four separate files.
VELAnalysis III was an updated version of VELAnalysis and included extra features such as moving average smooting, advanced graph selection, display and zoom features and built in maximum, minimum, mean and RMS plotting are available.
VELAdisc+ from Sarge Software provided similar functionality to VELAnalysis III. Rather than overlaying different graphs over each other, VELAdisc+ allows for upto 4 graphs to be shown in "windows" on the screen simulaneously.
The VELA Utility disc provides further analytical tools in support of software such as VELAnalysis and VELAdisc+. It specifically supports data files produced by VELAdisc+ and VELAd but can be configured to support loading data files from other software by configuring the position of the first byte of data in the data file to be loaded.
The software also provides a full 6802 Assembler and Disassembler and supports displaying sample data in real time and downloading memory ranges directly from the VELA into the disassembler when the VELA is fitted with the ISL2* and ISL3* EPROMs.
When I acquired my VELA, there was no accompanying software so I started to develop my own and I'm now releasing an initial version for people to use. The software can transfer data from the VELA, save and load data sets for future analysis, render graphs, perform custom functions on the data and create smoothed graphs from the raw data.
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.
