AMD AM25S09: Quad 2-input High Speed Register:


--- Code: ---.25S09 16

--- End code ---

The last 8 lines are a bit redundant but it checks the chip with either STB held high or clocked (low-high-low pulse).

First 5 lines checks interrupt function and after that the inputs and outputs are tested.

channelmaniac:
82S25 is the same as a P3101 for testing.

Here are a few more:

8T38: The first 2 test the chip from Bus to Out (Input to Bus outputs disabled.) The 3rd tests the Input to Bus when the Input is high. The last three are a bit redundant.

8T96: Autofind will find it by itself. It's similar to the 8T98 but the enable lines must BOTH be toggled for all gates to be enabled.

8T98: Autofind will find it as either an 8T98 or an 8T96. The enable lines are separate on this chip: One controls 2 gates and the other controls 4 gates.

channelmaniac:
8T95: Identical to 8T96, but with non-inverting outputs:


--- Code: ---.8T95 16
11Z1Z1ZGZ1Z1Z11V
10Z0Z0ZGZ0Z0Z01V
00L0L0LGL0L0L00V
01H1H1HGH1H1H10V
--- End code ---

8T28:


--- Code: ---.8T28 16
1ZL0ZL0G0LZ0LZ1V
1ZH1ZH1G1HZ1HZ1V
00L00L0G0L00L01V
01H11H1G1H11H11V
0L0XL0XGX0LX0L0V
0H1XH1XGX1HX1H0V
--- End code ---

8T26 is like the 8T28, but has inverted outputs. Wouldn't be too hard to create from the 8T28 script.

channelmaniac:
Some serial interface chips:


--- Code: ---.26LS31 16
0LH1HL0G0LHXHL0V
1HL1LH1G1HLXLH1V
0LHXLH1G1HL0HL0V
1HLXLH1G1HL0LH1V
XZZ0ZZXGXZZ1ZZXV
.26LS33 16
10L1L01G10LXL01V
01H1H10G01HXH10V
10LXL01G10L0L01V
01HXH10G01H0H10V
XXZ0ZXXGXXZ1ZXXV
.1489 14
00H00HGH00H00V
10L10LGL01L01V
--- End code ---

Can't do a 1488 as pin 1 is a negative power pin.
