The (later) LPS series was indeed 1" with the most common models being 52 & 105 MB.
Ah, yes. I had two of the 52MB units. Gave them away or recycled them, not sure which. Wouldn't mind having one back for my TI system.
Staying involved in "retro" systems just reinforces my bad pack-rat tendencies because of all the things I've thrown out which I *did* eventually need.
