Last thing I need is more HP1K's... but I'm
always looking
out for a
few
This is one series of HP computer that I've never been
inside. So if anyone knows of any available in southern
England, I might be interested... Particularly if they're
relatively small...
Well, if it's on my side of the big water, I would interested.
I believe we're both on the same side of the Pond.
Now, from what I've read, the HP1000L (I
think that's the
small one, isn't it) used an HP custom CPU chip. But I have
what appears to be a CPU board from such a machine built from
4 2901s, a 2910, and microcode PROMs. What do I have? What
machine should I be looking for to find a complete system
using that sort of CPU board?
The HP 1000 A systems A600+ I've one of those, they run RTE-A .
YEs, having looked at the picture of the CPU board, it appears to be the
board I have . The A700 looks to be not too much custom either (apart
from those 3 PGA chipss on the FPU, presumably ASICs
for the data path).
I'd love to find one of either of those machines.
But it appears fate has decided I am not going to get an HP1000. On 3
occasions I've nearly got one, and then not ended up with it. Once was, I
think, my fault, it was _years_ ago and I didn't realise what it was.
Another was given to a friend of mine, we lost touch, and I think he gave
his entire collection to Bletchley Park. (I don't know what model it was,
but he descibed the CPU as 'made of 2901s'.
And the last one is the one I have the CPU board from. An ex-friend of
mine (you'll see why he's an ex-friend) was given it. He decided he
didn't want it and threw it out, after pulling the 3 PCBs from the card
cage, which he then gave to me (these appear to be the CPU I described, a
RAM board, and an HPIB interface). For all he knew I loved old HPs, he
didn't offer me the entire machine. But that wasn't the first time. He
was great and convincing me to give him stuff, but never thought I might
want it back when he'd tired of it. Oh well... Another thing he threw out
was a rare Sanders 12/7 printer, for all he knew I have one and could
have used the font ROMs, printhead, mechancial parts, etc. Oh well...
