What sort of Apricot kit? If it's something like a Xen Xi, I'd be
interested.
Wasn't there something else you and I were going to trade a while ago?

NO it's someone that hasn't an idea how or what it is. RS sells a
universal
keypad kit (not usually stocked in the stores) that would work fine. One

Besides I obviously don't know anything about it even though I have a

i recently had the pleasure of meeting someone who once worked on ENIAC...aside from hearing some stories about the computer he also has several tubes from it laying around which, if he can find, will soon be mine....

I have three working plus a TK50 in an external box (same box), if that
isn't enough I must have 6 or so of the PSUs that I use for "projects".
The PSU wants a 10W load minimum on both the +5 and +12.
It's rated 160W OUTPUT. It easily runs a P166 with options.
The +12 is heafty enough to run a MAXTOR2190 with reserve
figure it for not less than 4A.
The remainder is on the +5, If memory serves it's good for 12A++.
The minus voltages are for RS232 type use figure them for .5A.
The "floating line" is powerfail and is open collector. I rarely use it.
Have fun

The keyboard was the common type similar if not the same as most
calculators of the time used. Simple XY matrix of switches and easily
replaced.
The biggest problem of the keypad is the materials didn't age well over
time. Many still
work well.

I just received a 3100e/40, and have installed the setup program, but
want to install a simple word program, but am having trouble doing it.
Does anyone know the steps which I have to go through to install such a
program?

Yes but I am sure the front one has a sensor also since the slightest
heasitation there also shuts it down.
I have not taken the time to find a front sensor but it must have one.

The rear one is not bad but the front one does involve some alignment.
Again I have not taken the time. I did try lubricating the top bearings
with a syringe and still had problems. I then removed it and did the bottom
bearing. It ran free then but I had alignment problems and no alignment
tape or info. At that point even with over a dozen drives on the way to
scrap metal it was not worth any more time to me.
