My uBee's were mostly made up from bits. Living near Gosford, the final
home of the company, was handy when they had their closing down auction.
I can't remember which uBee applcation or data it was but I was
successful in converting it from CP/M to DOS with Alien.
32k of RAM and a single 720k floppy, it was like having all of one's
Christmases arrive at once after months of saving and loading from
cassette tape. Don't complain to me about your P4 with GB's of RAM being
slow!
I used dBase II in a semi-serious way on the Bee and was then lucky
enough to get a version of dBase III for DOS. I had great difficulty
coming to grips with the programming difference in dB IV when it was
available.
I tried packet on mine, but bought a second hand IBM XT (4.77M and 640k
RAM, with 2 x 360k floppies and no HDD) just in time to preserve my
sanity, which I've since lost completely. Paid the princely sum of $100
for it around the late 1980's.
