Atom ROMs

Postby Boydie » Sun Jan 21, 2018 6:15 pm

I've finally got round to imaging the expansion eproms in my Atoms. I would have expected the 3 Econet roms to have been identical, but they're not so there may be some eprom degradation going on...

ISTR being told in the early 90s that FP is some sort of floating point extension to Basic. ONLI allegdedly stands for Online Basic, but I really don't know.

No idea what the Mystery rom does - it's only a 2516

Anyone know Paul Bond from the Econet Roms

Code: Select all

Do you know if they work?
Seems to be Econet 2.40 ("04.2 TENOCE" near the start of the roms)

MYSTERY is certainly new to me.

It contains the following commands I think:
START
KILL
RQIN
RCLK
HANGUP
DEFPORT
PORT
TIME
COLOUR
XADC
TIME
PORT
REACT

HANGUP, so maybe a modem ROM?

ONLI also contains those same commands.

Econet 1 and 3 are the same, Econet 2 looks like pin D7 is stuck at 0.

Don’t know if the econet roms work. Having a running econet has been on the to-do list for the past 20 years at least. Before I found them under a store room table in 1993, the atoms had been used in undergraduate teaching on an econet administered by a system 3, so it’s pretty safe to assume they were functional at some time.

Wonder if the mystery rom was to allow it to work as a dumb terminal for logging onto the university mainframe (a rather primitive phx rom).
