Before (and after!) I was so rudely interrupted by yet another useless Maxtor DiamondCrash hard drive...
U43-47 - RAM Sockets
U36 - Boot/RIPL ROM

U48 - Pads for PGA IC
U42 - MAC Address (00-01-C8-5E-11-D9 for this adapter)
U40 - Texas Instruments TMS380C16PQL

U24 (left) - 4046-24A
U37 (right) - 4046-37C
U50 - TI TMS38054FNL
X1 - 64.0000MHz
K1 - Pads
T1 - Valor LT6023
T2 - Valor LT6023
T3 - Valor FL1013
JP1 - RAM Density Select (left 4M / right 1M)
P6 - Six pin header, function unknown
JB1 - TR Cable Type Select (left for Type 3 (UTP) / right for Type 1 (STP))
Total Hardware '99 seems to have the numbering on the jumpers reversed.
The Type 3, Type 1, 1M and 4M options are correct based on what is
printed on my adapter. The cable types represented by Type 1 and Type 3
may be wrong.
What is the purpose of P6 on the board? I can't trace it visually, as the board material is too dark.
Per the documentation, the green LED indicates a valid link. The red
LED indicates activity on the ring, such as sending or receiving data.
My experience (below) differs from this, perhaps the Windows NT 4.0
driver doesn't utilize the LEDs in the same way?
LEDP1 - When the adapter attempts to insert into the ring, the red LED comes on first, followed by the green LED. After the adapter opens (the MAU usually "clicks") the red LED gets slightly brighter and the green
LED remains on.
The RAM sockets are unique "two in one" sockets that will accomodate
multiple types of RAM chips. From the factory, the adapter appears to
come with 5 4464 DRAM chips, for a total of 128KB RAM. You can upgrade
to 512KB using 5 44256 and 2MB with 5 441000 DIP RAM ICs.
Set JP1 to the 1M setting when using 4464 chips. Use the 4M position for all other types.
Drivers and OS Support
I've got this adapter running under Windows NT 4.0, which ships with a
built in driver. It runs well and seems to work very well in a 9585-0X0
with the stock soldered 486SX-33 CPU.
I have no idea what other operating systems have for driver support, as
I haven't tried them yet. I also don't have any of the original
Thomas-Conrad drivers or supplemental files. If you have anything
relating to this adapter (files, diskettes, manuals, etc...), please contact me!
Louis Ohland dug this listing up:
Internet Archive doesn't have them.... I did get the names, though...
