5250 Emulation Adapter/A
U4 Intel N8259A PIC
U5 Siemens SAB 8088-2-P
A,B,C KM44C256BJ-10 256Kx4 DRAM
Y1 24.0000 MHz osc
The port is a male DB-15 (not HDD15) The card is marked 93X2695 and another
sticker says "To replace card order PN 69X6294".
From Fred Mau:
15-pin *male* connector on the PC board? Almost has to
be a 5250 Display Station Emulation Adapter (DSEA), It's the only cards
Ive ever heard of that uses a 15-pin male. It allows a PC to act as a terminal
on an AS/400 twinaxial network. There should also be a pigtail about 12"
long with a twinaxial T connector on one end and 15-pin female on the other
end that attaches to this card.
My HMM shows the (early, for system 36/38) 5250 DSEA as
being a 69X6294 or the (later, for AS/400) 5250 DSEA as being a 64G3506,
but maybe there were some variants.

This allows you to choose the memory address for the adapter.
Each adapter must have a unique address range.
C4000-C5FFF, C8000-C9FFF, CC000-CDFFF, D0000-D1FFF, D4000-D5FFF, D8000-D9FFF
; DE000-DFFFF, C2000-C3FFF, C6000-C7FFF,
CA000-CBFFF, D2000-D3FFF, D6000-D7FFF, DA000-DBFFF
I/O address for adapter. Each adapter must have a unique
01800-0187F, 02400-0247F, 02800-0287F, 05400-0547F, 0A400-0A47F, 0E000-0E07F,
Interrupt level for the adapter or disable the adapter
Interrupts 9, 10, 11, 12 will be implemented in the future,
at which time the comment marker will be removed. (Ed.
Note that Disabled is commented out..)
