Found this on Wiki: "The VT61 and VT62 were block-mode terminals. The VT62 was to be used in conjunction with TRAX, a transaction processing operating system on high-end PDP-11's. They used the same cabinet but had a more complete custom processor. Application-specific behavior was coded in separate PROM memory, using a separate instruction code that the processor interpreted. " Any idea where we could get a copy of TRAX? Then it's just a matter of running it on a PDP-11, emulated or real..:) sampsa <sampsa at mac.com> mobile +358 40 7208932 On 28 Sep 2013, at 02:36, Bob Armstrong <bob at jfcl.com> wrote: What can be done (non-destructive suggestions only, please) with a VT-62? This is NOT a VT52 (although it looks like one). The VT62 is a block mode terminal that, I think, actually speaks DDCMP. AFAIK it's incapable of being a plain ASCII terminal unless there's some hack I'm unaware of. Right now the only thing I can think of is to part it out as spares for my VT52. I have two of the latter and it looks like at least some of the major assemblies - CRT, keyboard, power supply - are identical. I hate to do that, though, if there's a better use for it. --- Bob
