Replacement ULA for Spectrum+128 / Spectrum+2

SLAM128 is ULA CHIP CPLD replacement
SLAM fits only in ZX Spectrum 128 toastrack and Sinclair ZX Spectrum+2 (grey case).
Not for ZX 128 A/B models in black case !!

Device was designed by Mark Smith; later on supplied / assembled by Zaxon.

As project was set free and I needed ULA, i decided to redesign a liitle bit PCB and after tests, i have introduced re-worked version to my offer.

CHANGES comparing to orginal design:

my version of SLAM supplies all ncessary clocks for ZX SPECTRUM; if Your pcb has problem with 17MHz clk, device will help ( why ? look at schematics... no need to divide frequency, then to mutliply it.. Epson programmable clock geneartor present at pcb; PLL removed from design)
lowered 8% input volume needed to drive ear input
4 layers pcb
