Troed just pipped me to the post. Ive just found my box of RAM and unpacked the 30 pin stuff. Unfortunately, they are all 70 or 80ns rated apart from four sticks which I believe to be 256Kb SIMMS that are 150ns. They are identical to the top set in Troeds picture (with the Siemens chips), other than...

Yes you can. For an extra £10 p/h. I would consider it if we had someone wanting to hold a seminar or some practical use for it, but otherwise, people are mostly there to look at the retro gear. It seems a bit extravagant hiring it just so we have somewhere to eat out lunches. :lol: However, Im alwa...

Maybe we can have them atached to one end (if that makes sense?) Like a letter 'E' shape.

It would just mean people would have to walk back again rather than being able to do a loop.

Thanks @exxos

As you can see, its not a bad size and actually quite wide too, so I think we can have some tables set more centrally.

Yeah, theres probably some sort of tolerance or other variable Ive forgotten about over the years. I'll just send you the SIMMs and you can see what does and doesnt work.

Done.

Well, slightly bizzarely, Avril has sent me some very short video clips of the hall, instead of some photos. I suppose thats fine insofar as I personally can get the jist of the hall size. But it doesnt help showing you guys, as the file sizes are 12-19mb; well over forum attachment size. :roll: Any...

BTW, Im going to have a good look for the SIMM box tomorrow (when I can bang about without consequence!), so Im still on the case with this. However...80ns is 12.5 Mhz, so something thats 100-150ns is in the ~6-10Mhz range...250ns is 4Mhz. These are very early SIMMS and I would have thought most of ...

What? You mean like the C128?

Oh dear. When I wrote this I actually calculated the age using the flawed assumption that we were in 2025!
The C128 came out in 1985, so no, its not 40 yet. Maybe next year then?
