Nice, I have been thinking about a 475 or similar for some time now but the thought of hybrids fills me with dread, but that is only based on the repair videos I have seen on line where it nearly is the hybrid thats gone and the troubles they have locating them.
If I was go for a Tek, it would have 150Mhz upwards and I already have a Rapid 25Mhz, Hitachi 40Mhz, Iwatsu 60Mhz, LG 100Mhz and a HP 1740A on the bench being repaired, but if I'd need to sell the Rapid I think, break my heart to do so as it really is in pristine condition and has only had a few of use in its life, but it is the least capable of them, so logic says it is the one to go first.
Am I right in thinking that the IBM 475 is exactly the same as the Tek 475 but it also sports the IBM logo, presumably because they used them on their computers and wanted them customised with their logo? Or is even deeper than that and has custom functions / ranges for their use?
