Anyone on the list belong to the local Houston HAAUG club? Their website has
gone offline since Friday (12/12). Wanting to know if this group is still
active? Thanks
All,
I was recently given an Olivetti luggable.
http://personal.nbnet.nb.ca/gallante/olivetti.html links to a page on the
same model machine.
With a bit of work the system is running well, it has cleaned up really
well and looks to have been lightly used at best. The insides were VERY
clean considering its age and the conditions it had been stored in. There is
no burn on the CRT and the display is clear and crisp. :)
The motherboard is labeled 'Corona Data Systems' and is serial number
0160. Various dates indicate the system was built in 1983. I find several
references to 'Corona Data System', it appears they were sued by IBM and
lost over copyright infringement. I'd be curious to find out if this system
is one of the ones that infringed on IBM's copyrights.
At boot it POSTs the following:
ROM Version 1.53
Testing Complete
512K Memory Installed
512K Memory available to DOS
I've been able to boot several versions of DOS, and have formatted a set
of working disks. :)
I'm looking for more info on it, searching the web only provides the one
link listed above.

Very possibly, though it's often impossible to tell who actually fitted
the replacement EPROMs -- DEC sold them to people on self-maintenance
and to third-party maintenance companies like the one I worked for.

Yes, because that's about the only useful distinction -- the speed
increase brought by PMI memory is more than the clock difference
between 15MHz and 18MHz -- and of course if placed after the CPU, even
a PMI-capable memory board operates as normal Q-Bus memory.

Ah, I like to poke the switches, see the lights and hear the fans :-)

Does anyone recognise the following DEC module?
HIGH SPEED MOS MEM MAT MS1440 G401C
This is THE most unusual DEC board I've ever seen personally, and also
the most
beautiful.
This board has an extreamly early example of an LED in the upper right
hand corner
where a machined metal stiffener is used in place of the usual cast part
used on other
Unibus boards. This stiffener appears to have been milled out of an
extrusion, by
hand. Nylon hardware is used along with the more conventional eye-ring
rivits.
The outside edge of this milled part is stamped 'G401'.
This LED is made from a gold-clad machined metal case unlike anyI've
ever seen
(including those seen on the LED museum web site). I can't see the
part number
on the case, but I'd bet its a Hewlett Packard. This LED alone may well
be worth
more than the whole module!
The IC's are an orderly mix of grey plastic, gold leaded Intel
P1103-1's, and gold on white
ceramic (with grey lead-frame traces) Intel 3207-1's.
Arrays of individual resistors form high speed DC terminators for the
arrays of 1103's and
3207's, and a small handful of TTL parts complete the list of chips.
The TTL datecodes suggest its from 1970.
The memory chips are not so easy to understand, the P1103-1's are marked:
P1103-1
0531
And the 3207's are marked:
3207-1
S183
B0536
Both feature a large 'i" logo to the left of the markings. Clearly very
early Intel parts.
I suspect that this ~may~ have been a 'live spare' for a PDP 11T55 I
once owned
and ran many years ago. If anyone knows what this board is, I'd love to
know.
I can try to get a digital photo made, but that may take some time. If
someone 'just
has to' own this board, I'm willing to talk. The overall condition of
the board is excellent
and very few of the decoupling caps have scratches from installation and
removal. The
unusual edge-stiffener also shows unusually little ware.

Hi
No, this is a uP. this part is way to early to be a HC anything.
Maybe I got the number wrong. I'll check it and be back tomorrow.
It is from a Poly 8813 floppy controller board. This is a hard
sectored interface so I suspect that it is some kind of USART.
I was getting the number from my memory instead of writing it
down.

Maybe you meant 6852, which is a Synchronous Serial Data Adaptor.

Cool - my chance to flame for the holidays!
If you're on this list and thus interested in "classics", the 308 is way
too nouveau - anything with less than 12 cylinders (street cars only - I
would never discount the 4 and 6 cylinder comp cars or the 815) is only
a cost-reduced shadow of a "real" Ferrari!
Forza!
(and of course, hohoho and Best Wishes to All)

Hi Al
Thanks. I expect that is what my dyslexic mind didi.
I guess that is the one I need specs for.
