I still need to do my DMA bodge boards It makes me wonder if in years to come people are going to be asking what that little board is for, just like people keep on asking what the blitter bodge board is in the MEGA's etc
Naa, just build your own bodge board, much more fun
Collector of many retro things!
800XL and 65XE both with Ultimate1MB,VBXL/XE & PokeyMax, SIDE3, SDrive Max, 2x 1010 cassette, 2x 1050 one with Happy mod, 3x 2600 Jr, 7800 and Lynx II
Approx 20 STs, including a 520 STM, 520 STFMs, 3x Mega ST, MSTE & 2x 32 Mhz boosted STEs
Plus the rest, totalling around 50 machines including a QL, 3x BBC Model B, Electron, Spectrums, ZX81 etc...
Below you can see the first socket ready for either the Three Amigos board or Three Amigos + MAD10 board. FPGA board is still in Eagle at the moment. You may notice a small jumper pin on the SIMM socket. Thats the MAD10 line. My OCD is a little off that I could not do the MAD resistors in SMT.

Soooo much neater without sockets and with SMT resistors and caps.

@terriblefire Was going to build the Alpha with SMT stuff as he loves through-hole so much
Utterly hate the stuff. Through hold must die.

All that is left to do is two patches on the H4 Development Strain Edition I cant help naming things.
Not bad as I think I started building these three boards last Saturday.
The header sockets in the PLCC locations I found a few pins a little tight so just a little small wiggling they eventually go in place. This is pretty bare bones I am not putting any rear sockets on other than serial port to diagnose if this doesn't boot properly.

Below is a close-up of the plug-n-play area for stock to whatever else we want to play around with around these chips such as the yet to be tested MAD10 (16MB schematic) and eventually an FPGA board.
