Back in the day, at Iota, we certainly supported databases that wouldn’t fit on
a single CD-R… that makes them more than 650MB… they typically had lots of
photos embedded in them. I seem to remember a user who had to split his
database over three CD-Rs which takes it well over 1GB. They didn’t then fit
onto the hard drive of a ‘standard’ RISC PC so we rebuilt it on our server,
then Bertie or Neil rebuilt it - they were clever guys - and we split it and
sent it back!
The last Mac version we built was 2.19, for Power PC processor, on System 9. It
was before Mac OS X came out… it ran on OS X for a while but had died
completely and wouldn’t run on Rosetta when Apple switched to Intel. Would
probably be easier now to compile for an M1 (ARM) Mac, but there’s no way that
code base would be supported on the modern tools, and sadly of course, Neil
died many years ago.
Has been a bit of a nostalgia trip taking me back to a fun year running Iota in
1998!

Chris,
Just out of interest what is the largest database any of you have
constructed with Datapower?
Currently the database is holding just over 52,000 individual records and
measures 7MB in size.
Over the years I have helped with a lot of user's databases. Mostly they
have been cut down versions and so relatively small. The largest was one
dealing with a school and was about 7MB.
CJE also had a 7MB database for their catalogue but that has probably been
superseded because it was too slow.
Of course some databases may be relatively small but access a lot of
external data. One such was "A multi-access key to the lichens of Great
Britain and Ireland". It was - and may still be - a commercial product. I
was asked to resolve a few problems with it - which I did. The actual
database was not as big as yours - about 3MB - but it accessed and
displayed location maps and photos of the lichens. These were stored in
external directories. The maps occupied 16MB and the photos 42MB.
