03Jan22		swopped A3,A5 on 74138 so A5 is in-C and A3 in-A, and moved AY select from !O1 to !O4
		Address of AY is still 33,37 but now addressing makes sense.
01Jan22		padded outsides of eye recesses to take screws holding backing plates for the eye plates. 
		Trimmed the edges of the eye plates to fit in the eye recess rather then just sit at the 
		back of them held in place by the spring clips which are now not needed and are removed.
30Dec21		cut off the front of the top cover just behind the eye recesses.
		Now can run with the central cover off and the LEDs in place.
11Dec21		added to Amp input 15K+22uF fed from 1Mpot from Ace Sound. 
		however AY-sound still upsets things, added 100k in the feed from the AY - better.
10Dec21		after AY-Sound, Speech is now distorted!! OK if AY-sound never used!! Capacitor charging?
		added 22uF inline to AY feed to Amp. 
Dec21		removed 'spaghetti' pink 5v,0v wires.
		Added Red/Black wire from 5v,0v rails at top and bottom of PCB.
Nov21		Sound and Speech work
Aug21      	removed BEC, added Astec 5v regulator board for electronics, added another Astec board for motors
19Jul21		wired RAM socket on RAM board I made in the 80s, fitted 8kbRAM - works
Sep20		BEC mounted on Ace
23Aug20		software understood, UART needs initialising for SP0256 to work, AY38910 Dirs need setting.
		Speech and I/O work, not checked Sound generation.
		However changing from Fd to Bk crashes computer, BEC just needs to feed computer.
18Aug20		Cut topshell in half, sanding sealered cut edges
14Aug20		added 5v BEC after 2.5 input, now safer. 
		BEC runs motors as well, when Ace working mount BEC on Ace and motors on raw 2.5
13Aug20		rewired bump sensors
11Aug20		cut top off Caster well and repositioned top plate 5mm lower (as per my drawing)
		more room for D9,D15 wiring now
10Aug20		made bracket to hold D9 and D15
03Aug20		finished power rewiring of base, added 2.5 power connector to port panel.
28-07-20	Trued caster wheels, removed copper wire tyre and reshaped with 1/32 x 3/16 rim
		now works much better.
		Drilled, sanding sealed, grey primed holes for motor wires 
27-07-20	made adapter for relay board to 2x5 header.
		drove M1 from puppet keyboard, 
		caster wire tyre catches in floorboards (tramlines)
