How to lose most of an an entire collection in one shot

I am sure yuo realise why I prefer the series 200 to the series 300... Perhaps I am being unkind -- the only 9000/300 machine I'ev been inside is the model 340, and it seemed to be stuffed with unrecognisable PGA-packaged ICs. At least the series 200s are mostly standard parts with the odd PAL, ROM and microcontroller thrown in. It is an interesting styling and odd to work on -- release a quarter-turn fastener, slide the casing slightly forwards on the stand, then lift it up on a stay. You can then release some Nylatch clips and lower the processor board to work on that, The HP120, BTW (and the oriignal HP150, which has much the same physical layout) is odd... You can remvoe the top casing with 2 quarter-turn fasteners, but that jsut gets you to the PSU and monitor PCBs. To get to the logic boards, you have to unclip the battery pack, then remove the jackposts on all the connectors, and then remove 5 screws and the rear panel of the card cage. -tony
