Re: [M100] RESEQ.100
Thanks Brian. I'll take a look but when I was reminded that rom2 has this function and it seems to work flawlessly, it took the wind out of my sails a bit. I also was looking at the Microsoft version of this command via the nec rom. ..Steve On Friday, July 16, 2021, Brian K.

Interesting - the discussion is all about how to port it, but they don't discuss the flaws! On Fri, Jul 16, 2021 at 7:45 AM Stephen Adolph wrote: > Thanks Brian.

It's really cool, I like it a lot. The PLA you used for the case is a really close match to my T102, which is cool too.

Re: [M100] Sneak peak and small first offering of the new 'Backpack Drive'
If anyone is curious about the PLA used it is from PrintedSolid.com, Jessie PLA 1.75mm X Beige 500. I like to call it ‘old computer beige’. Jeff Birt (Hey Birt!)

[M100] Howdy! New to list, need some parts…
Howdy! I’m new to the list and recently picked up a model 100 that needed some restoration. A friend helped me get the bad caps replaced, cleaned the power plug and we diagnosed a bad member switch and bad pot for the lcd contrast adjustment. It’s working again (hurrah), with a solder bridge on the switch and some resistors temporarily in place of the pot. ( we also removed the battery before any leakage or damage ) Is there anyplace where I can get replacement parts for the pot and switch without digging thru a Mouser or Digikey catalog? ( or the part numbers at least to save a number of mis orders? 😊) Earl Sent from my iPhone
Re: [M100] Howdy! New to list, need some parts…
Usually DeoxIt clears up the contrast pot. Just spray it, don't worry about overspray, operate it a few times, wait an hour, operate a few more times, then possibly wait some more for the interior to dry. Can possibly take as long as a couple weeks if it was really drenched. The entire screen may go faint while it's wet but it comes back as it dries, don't worry if you see that. Also check for bad solder joints since the pot is subject to mechanical force from outside. Always possible it took a hit somewhere along the way in 35 years. bkw On Fri, Jul 16, 2021, 10:28 PM Earl Baugh wrote: > Howdy! > > I’m new to the list and recently picked up a model 100 that needed some > restoration.

Re: [M100] Howdy! New to list, need some parts…
Same thing for the memory switch. Just hit it with deoxit at work it several times. It should be perfect in a few seconds (No potential 2 weeks drying time because it's not a tightly closed enclosure, plus it's a crude power circuit not a super sensitive signal like the contrast pot. It works fine even while still drenched). Never heard of the switch actually being bad other than just dirty or oxidized. If you removed the memory battery but didn't put a new one back in it's place, get a new one and install it.

Hey Earl, Welcome to the list. Deoxit on the pot. Amazon has it in a "precision" dropper here: https://www.amazon.com/dp/BYH6F8/ref=cm_sw_r_cp_apa_glt_fabc_HYHBJZ4YAQW7PX7RC30P Greg @ arcadeshopper.com has most parts you'll need. Including complete re-cap kits. Just picked up a couple kits with a replacement TPDD2 belt myself.
