[Asking this for a friend who picked up a Lisa for $180 at a
hamfest. He wants to keep it as a Lisa, as the whole reson he
bought it was novelty value. I couldn't find a comp.sys.lisa, so
this looked like the best bet :-)]
LOTS OF QUESTIONS!
WHAT MODEL?
---- ------
Says on case: Model number A6SB100. Memory option A6B108.
APPLENET 00100254. Manufactured 83053. Has parallel port on
back, which is not shown on pictures in Lisa 2 manual.
INTERNAL HARD DRIVE
-------- ---- -----
Lots of space inside for a hard drive. Can one be hooked up?
With what connector?
HD INTERFACE
-- ---------
Apple ProFile, modl #A9M0005. 25 pin female connector (SCSI?
parallel? sort of works when connected to parallel port on Lisa)
BIGGER HD?
------ ---
Can a bigger HD be put inside the ProFile? Currently contains a
Seagate ST-506 5 meg drive (full height :->). Could a 30 meg or
so ST-506 interface drive be put inside? What would have to be
done to use it?
UPGRADING TO MAC
--------- -- ---
System came with "Macintosh system 2.0 prerelease" disk, which
boots ok. Can this thing be upgraded to a mac, and if so how?
Could it then still be used as a Lisa?
UPGRADING LISA ROMS
--------- ---- ----
ROMs are 341-0175 and -0176, REV C. Are there more recent
versions than C?
FLOPPY DRIVE
------ -----
Single sided, presumably. Can read the Mac disks, but doesn't
boot off the Lisa disks (Lisaguide and the system disk). Any
ideas?
WIERD FLOPPIES
----- --------
System came with pascal compiler, which comes on some 5-1/4"
disks the likes of which I've never seen. Any way to get this
software on 3.5" disks? The disks have two head-access slots,
180 degrees apart, and have all sorts of extra notches and
holes.
EXPANSION BOARD
--------- -----
Has 3 25-pin female connectors, one of which is unaccessible
when the cover is on the machine! Model number SK1285-01 printed
on board, written on the board by hand is SK1356-01. What is it?
MEMORY
------
Has two boards, supposedly 512K each. Can more memory be added?
The boards currently installed are 620-01 (hand written was:
12-B)
EXTERNAL MACDRIVES
-------- ---------
Can external mac floppies be hooked up? Where to?
DOUBLE SIDED DRIVES
------ ----- ------
Can a double sided drive be used?
INFO ON PRINTER
---- -- -------
Apple Letter Quality Printer, model A3M0025. Daisywheel printer.
Is this a standard serial connection? Can replacement typewheels
and ribons be obtained? Any special features/capabilities/problems?
Any help is *GREATLY* appreciated! Please e-mail respones only.
Thanks!
