NES PRG TSOP Adapter

2 layer board of 1.59 x 0.60 inches (40.3 x 15.2 mm)
Uploaded: July 29th 2023
Shared: November 1st 2023
Total Price: $4.75

NOT FULLY TESTED! I had tested this adapter board with a 29F800 and it was not working. However, I'm almost certain that I programmed the memory chip wrong. The adapter probably works. But use at your own risk! I will update this if/when I have a chance to test it again.

This is an adapter that will allow you to replace the 73LS00 with a 74LS139 on a SHVC-2J3B-01 PCB. This may only be useful for a single purpose: To put the fan translated Final Fantasy 5 on an authentic Final Fantasy 5 SFC cart that uses the 2J3B board by using three 27C080’s.

SNES TSOP-DIP Backside Adapter - Rev.B

2 layer board of 1.79 x 0.62 inches (45.4 x 15.6 mm)

Total Price: $5.50

So far only tested with an 8Mb game on a 29F800 in a 32-pin socket, and found to work. It should work fine with a 29F160 since the only difference is one additional address pin.

This installs on the backside of a mask ROM. You must cut/isolate the /OE pin on the mask ROM and tie it to Vcc.

ATX PSU Latching Circuit for Mom Power Switch

2 layer board of 0.99 x 1.00 inches (25.1 x 25.4 mm)
Uploaded: May 27th 2023
Shared: May 27th 2023
Total Price: $4.90

This is a simple circuit that will turn on an ATX power supply using a momentary switch. I made this specifically to use an AT style motherboard in an ATX case. The mounting hole is sized to fit a 6-32 screw so that you can mount the board on an unused standoff.

I'm using one of those common AT…

SNES MAD-1 Piggybacker for 74LS139

2 layer board of 0.78 x 0.75 inches (19.7 x 19.0 mm)

UNTESTED! But should work fine, since there's not much to it.

This is a small adapter for a 74LS139 that mounts on the backside of a MAD-1 decoder. Use it to connect multiple (max 4) PROMs to the MAD-1.

0.8mm thickness is preferred for easier soldering, but 1.6mm thickness is probably fine. …
