Which PDP-8 is this? (ebay: 261232211533)

For it's time (pre 1970) it even could be the most compact complete computer available. You plug it into the wall and hook up an ASR33 and it works. The computer has many blinkenlights. And it's quite rare. All that makes it nice. On the other hand there's the lack of expandibility. And loading programs via ASR33 110baud paper tape reader is PAINFULLY SLOW!! Ok, the 8/L could be expanded with a paper tape reader interface. That makes it better. But it's all difficult with this machine. And 8K memory (with 4K in a separate 8/L expansion box) is the maximum you can attach. My favorite PDP8 is still the 8/e. It looks nice and is VERY expandable. And there's so much stuff and software you can use with that machine. It's amazing! And, of course, a pdp8/e is compatible to the 8/L. What runs on the /l runs on the /e as well. The /e is so pupular that new hardware for its bus is still made today (hehe :-) And not to forget: I *think* that the 8/e computer was the first computer with a universal CPU/IO/memory bus that resembles a PC. And it has a PSU that contains the fans, is part of the chassis walls, and has the power switch attached to it - like in PCs. The dimensions were a bit different but from this modular concept clearly pointed towards was later known as a PC. The Nova for example did not have such a design. All other computers I know from that time have memory buses, IO buses, and dedicated slots. The 8/i is expandable as well. The 8/L is in fact a light version (the l???) of the /i. But it's much harder to find expansion stuff for the /i today than for the /e. Kind regards Philipp --
