A friend of mine found an old card when sorting his stuff, and he
gave it to me. He has no idea what this card is, and so do I.
Can anyone help me to identify this card? here are his descriptions:
Kinda bad ASCII drawing of it:
-------------13 cm.------------+
I
XX1X X5XX I/O I
XX2XXX X6XX text I
XX3XXX X7XXX 7cm.
XX4XXX X8XX I/O I
I
-------------------------------+
IIIIIIIIIIIII
As you can see, its 13cm X 7 cm. It has 8 chips, represented in the
drawing as the lines with Xs. (each short line is one chip.)
The I/O parts are 2 small black plugs, with one of them (the top)
has a cable attached to it. (Its one of these flat gray cables
so common inside the computer. forgot their name..)
The cable is made of 20 lines...
The text part says: DRIVE 1 ^
DRIVE 2 ^
Each ^ simbols a small white triangle near each DRIVE # word.
This causes me to believe that this might be a drive controller
of a sort...
The plug-in part which you plug into the computer (drawn with Is)
got 25 of these.
Here is what every chip has written on it ([L] means a logo of a
company)
1)SN74LS174N
[L]RQ8248
(Logo is of Motorola)
2)SINGAPORE 8310A
[L] TBP28L22N
(Logo is unknown: a wild guess is Texas instruments. Dont bet on
it, though)
3)SN74LS323N
[L]RQ8309
(Logo is of Motorola)
4)SINGAPORE 8310A
[L] TBP28L22N
(Logo is texas instruments?)
5)74LS 132
[L] 5T9
(Logo is unknown: looks like a triangle with bold edges)
6)[L] 5E1 1
HD74LSO5P
(Logo is unknown: A circle, with another circle inside that is
cutted of in its edges with 2 lines in the top and buttom.
There's a bold dot inside the second circle. In the edges
of the outer circle there are 4 spikes, like in a aiming
mark of a weapon. the spikes are going out of the outer
circle, not in though.)
7) 8502C0
[L]M74LS259P
(Logo: looks like the mitsubichi car manufacter logo)
8)NE556N
