Simon, how timely of you. I just acquired a NorthStar Horizon yesterday which uses four 64KB memory boards (parity). Each board has four 9 chip rows of 16KB dram. I haven't got the documentation for this machine yet, the previous owner has it in storage with software as well (he claims) and said he might have it for me by next week. I'll let you know more details when I get the docs.

I've been lurking on this list for a good long while now, and some of the recent talk of Northstar crates actually prompted me to dig one out that I had aquired a good few years ago and promptly forgotten about...! Does anyone have any idea what sort of RAM cards the Horizon likes to play with? My system already has an (albeit flakey) RAM-16 card, and I have the remains of an old Godbout Econoram-II card, sans about half its chips. I have *no* idea whether this card was ever used with the N*. The machine is not in great condition, bless it; it seems to have been robbed of a couple of voltage regulators at some point in the past, and the full-height 5.25 drives are, I fear, past their best, and shall be retired gracefully. I think that the PSU could do with some adjustment, too; if anyone in the UK has schematics for any of these bits, and would be willing to make copies in exchange for money or eternal gratitude, please let me know! Still, despite it's problems, I suppose I should at least be grateful that I have at least found a manufacturer of hard-sectored diskettes! [1] Thanks.
