Professor Adrian Eddleston. Author of Encoder09 and Tea-Time.


Listed below are two of the e-mail's that I recently received from Professor Adrian Eddleston. Adrian is the original author of the excellent Encoder09 and Tea-Time for the Dragon 32. The graphics for Tea-Time were designed by Adrian's son, Stephen Eddleston-McGrath.
 
Both programs are now available for download from the software pages of this site.

Dear Stephen
 
I recently came across your Dragon 32 T3 extension pack. Your kind words
about Encoder09 have stimulated me to write. I wrote Encoder09 just after
being appointed as a Consultant Physician at King's College Hospital !! I
worked closely with Premier Microsystems in Croydon for some time writing
the manual and further developing the software. I also wrote the dragon game
teatime, with my son designing the graphics. Unfortunately, as the work
increased, I had to make a choice between computing and Medicine - and
Medicine won. I went on to become Dean of King's, and then the first Dean of
the merged Medical Schools of Guy's King's and St Thomas'. I retired at the
age of 60 last year, and am now working part time as the Chairman of the
Bromley NHS Primary Care Trust. I am still a computer enthusiast, but
haven't touched the Dragon for many years. The emulators will almost
certainly encourage me to do so again.
 
 I have a copy of the original manual of Encoder09, and a copy of my source
code (poorly documented I'm afraid!!). I'm going to go and look up the ??
instruction you mention in your text.
 
Thanks again for the praise, I certainly enjoyed writing Encoder09, and I am
pleased if people found it useful.
 
Professor Adrian Eddleston
 
 
 

Dear Stephen
 
I enclose a text file reproducing 3 of the appendices to the encoder09 manual which give the monitor and assembler command set. I would be happy for you to include my e-mail on your Dragon website, and the text file in any zips you wish. I am also happy for you to put Encoder09 and Teatime separately on to your web site. I am also enclosing a cassette file of teatime, made from an original tape using coco tools, since this also displays the loader screen (with my son's and my initials on it  - S & AFE).
 
One irritating point is that T3, which I agree is the best emulator, does not give any sound output on my machine (running windows 98 with an Aureal 3D sound card and DOS driver) in a windows box or in MS-DOS mode. MESS and Coco2 work fine for sound on this same machine. This is most irritating since the 3 voice reproduction of the dam-busters march in the high score screen in teatime was one of the real achievements at the time! I am using the correct SET BLASTER command in autoexec.bat. Any thoughts?
