Last thing: my Lisa show a D/A8 ROM.
While i'm testing, i get one time an error '23', that is, no system
disk. That was when boot from 'disk 2' in the menu. never able to get
it again...
Normally you get an error 23 when, passed the initial test, the Lisa
try to boot from
the floppy (the first device available when the hdd is not present)
and it do not find
any floppy inserted on it. If during the initial test and after the
first click you
press any key eccept the Option key, the boot menu is shown.
If you see 2 floppy icons, this is because the D/A8 Roms. These are
Lisa 1 Roms, and
Lisa 1 have 2 Twiggy drives. In your situation only Apple-2 can work.
Infact, when
upgraded to Lisa 2 with the 400K drive only the second flat was used
and connected to
the Lisalite board.
Goog to know ! I alway try to boot on the floppy with Apple-1, and have
to wait a while....
I ask myself if the second board I have isn't a H/A8 ? I will try.
I try to see where the cable that connect main board to the Lite
Adapter is connected, but I cannot see the connector without dismantle
it all, I think.
Is not easy to see without dismantle. Anyway the two cables are
connected that
connector in which the motherboard is inserted (looking from the back
of the Lisa,
it's that bigger on the left.
have to dismantle it...
Thanks you
