Hi all.
Is anyone interested in a fully working 2400 Black Star 2.4 GHz frequency counter?
Its one of the old school ones with sprung buttons to select the mode. AFAIK the calibration is OK, it seemed to work fine when I used it a couple of weeks ago and it has dual mains/battery mode with several C cells inside.
Also have four somewhat working AA1 motherboards, two heatsink/fan assemblies and other bits. These have 512MB+ 512MB DDR2 external, and will boot fine with just the board and no add-on PCB if you short two pins on the connector. Two of these have kludged input connectors where they failed due to input short on connector side but work otherwise, one appears essentially intact and one needs a new controller chip and/or new SATA connector where this needs to be added.
I have one DOA board, a dead battery board which could be resurrected with new cells a possibly OK 16GB SSD and a spare blank/? Flash chip, it isn't that as I tried swapping and it still does nothing but black screen, core voltage is not right...
Also have an AOA150 mainboard and add-on PCB which is unknown condition, probably needs reflashing.
Also have one new and one N/G 15" LCD panels originally from an IBM Thinkpad, unfortunately they won't work on my Dell but maybe someone has a use? the N/G one has a confirmed bad backlight though.
Just found two brand new Tektronix scope flybacks (!) if someone has a use. They are fairly small but are unpotted so should be OK for all sorts of HV projects.
High voltage spark igniter module, takes 1 PP3 and outputs fat juicy spark at about 1 Hz, just the thing for firing small laser tubes etc or other applications
Sirius 1 8088 motherboard set and other parts, also have a spare ancient 8088 CPU and socketed memory boards from an Ericsson machine. If anyone wants the stepper motors from the four 5 1/4" drives then let me know, they appear to be microstep capable.
Make offer on these via PM if anyone is interested.

How much for the *possibly* okay SSD? Is there any way to test it? o_o

Well bearing in mind it has some personal stuff on it.. You agree to low level format it if it works right? (nothing dodgy, just laptop backup before I gave up and put a decent PATA 1.8" in the thing)
Say £10 inc postage, and I will throw in that spare non functioning IDE one with the apparent controller fault when/if I find it. It might be fixable.

Put it this way, it was working fine when I took it out. Changed over the cable and it then stopped working. Not sure if the problem was with the MB or the drive itself but the board stopped recognising any drive about a year later so I suspect that it may be fine. As I now have two working boards I can certainly see if it boots up..
I also have a converter board, tried it on that and no go- possibly some subtle difference in pinout because it works with the two PATA hard drives but not anything else.
