Hi folks (especially fellow kids) out there,
using your easter holidays to dig through stuff in your parents' basement
can be fun...I ended up yesterday with a long-forgotten Fujitsu FANUC/Siemens
19" unit (in a cardboard box with lotsa connectors, replacement fuses and even
some paperwork for it) which gives me the general impression of once having
been used to control some kind of NC drilling/milling/whatsoever machine. As
I'm not very good at describing stuff, I called a friend and we took some
shots with his digicam. I can't offer them on a homepage like all the others
(haven't got one yet); will it work if I simply send them to the list as an
attachment to one of my posts?
The thing consists of a metal frame with a PSU as the base unit, a keyboard
PCB directly behind the front panel, a bus board (also upright-standing)
behind that, and three PCBs plugging into it from the back side. Two cooling fans
blow into the casing from the left side. The back side of the PSU held a
4.5V memory backup battery that made a gigantic mess by losing some of its
contents while in storage, creating bluish-white crusts on the frame and inside
the cardboard box...Except for one corner of the PSU regulator board, the
electronics were apparently not affected.
There is no front label telling the model or anything (Inside the machine,
there is a metal Siemens type label with the number 321/22113 on it), but I
remember seeing the thing together with a monitor (also 19" form factor)
labeled "SIEMENS Sinumerik ..."; I'm afraid my parents eventually tossed that some
time ago. Why didn't I always care about Vintage Computers the way I do
nowadays...?
The included documentation is:
-A4 "Siemens Sinumerik logbook" (empty)
-A3 "FANUC mate TG Maintenance Drawing" (from 1979, with notes both in
English and Japanese)
-A4 "FANUC Customer's Maintenance Instruction (for ulti-mate TG)"
-A4 "FANUC MATE TG Data sheet"
The last one gives a model (A03B-0402-B001) and a serial number (1883815),
October 1980 as date of manufacture, and Siemens AG as customer.
According to the rule that the processor "always is the big socketed IC", in
this case we deal with an MB8861H, a 40-pin DIL IC in a white ceramic
housing. The schematics call it the MPU (=Main Processing Unit?).
I am looking forward to your replies, especially as I hope to get a hint on
what the system is capable of. Perhaps even enough to persuade my parents
into keeping it and looking for a monitor somewhere...
