But those boards would be things like a processor card (which I think also has ROM and about 1KB of RAM), a keyboard interface, a datacomm interface, one or more cards for the display, and zero or more memory cards. Some of the cards (but not the memory) would also be joined at their tops by a sort of "frontplane" interconnect board. That said, there's limited interchangeability between 264X terminal keyboards. Once upon a time I swapped keyboards and keyboard interface cards between a 2640B and 2645A just to see if I could, and it mostly worked. Of course, there was the matter that the 2640B keyboard didn't have all the same keys, and its baud rate switch wasn't labeled above 2400. So far as the 3000's concerned, you could also use 262x (for x>1; 2621 will work for character mode but will not support VPLUS block-mode applications), 2382 (which is nice and small but has a 9" display), 239x, or 700/9x terminals. Or an HP150, which pretends to be a 2623A graphics terminal when it's not being a personal computer. BTW, I think you mentioned passing up some HP terminal keyboards, and you might want to stop that, as the keyboards have a habit of becoming detached from the rest of the terminal on their way through the surplus food chain. Once you start thinking about network configuration with NMMGR, a 264X terminal can be a problem as later versions of NMMGR were made to use the terminal's function key display area for some screens, and 264X terminals don't have a function key display area. I have no idea why NMMGR was changed; as near as I can tell it was mostly gratuitous on HP's part and NMMGR will still function correctly, you just have to know which function keys correspond to which functions on those screens. (Guess who was still using a 2645 as the system console and only hardwired terminal on his 3000/58. Fortunately, I did know which buttons to push.) On the other hand, the 2645 will run Space Invaders, and I wouldn't be surprised to find that the 2649 would too. A 7958 is about (a little larger than, I think) 100MB and will work and fit in a 3000/37 cabinet. 7958B is faster than 7958A if it matters. I think bigger numbers (e.g. 7959 and 796x) are larger capacities. -Frank McConnell
