    Default Model 4 128K badges.

    Does anyone know of anyone that ever had these things made up?

    I'm going to need a few and I don't want to re-invent the wheel if there are some already out there.

    Thanks

    Yeah, I could use 3 of them...

    I would love one and a 48K one. My Model III was a 16k that needed lots of TLC and I fully converted and upgraded.

    If anyone knows where to make one, and it requires a minimum run to get them, I'd love to go in with you and get a few. Heck I'd be willing to buy a run of them and just sell them for just cost, or split it for a few extras just in case I need one down the road.

    Couldn't be more than $1-2 a piece. I'd pay more than that just because it really bugs me when I see the 16k and 64k while retroing around the playpen.

    I need about 20, to start, so, I'd be in.

    I'm going to be parting out some Model IV "cans" (the shields, main board (one 128K and, at least, 1 64K) FDC and RS232) drive stack, power supplies, etc, etc. I have a good model III (except for the case top being cracked almost in half, but the CRT survived) but, I'm using that right now to test the Model 4 stuff.

    I don't know how I'm going to part it out though. Maybe as a Model III to Model IV upgrade with the mainboard and keyboard, maybe the drive stack, drives and FDC (and spare 30W power supply, if needed) for a diskless Model IV, maybe the same drive stack and controller arrangement for a diskless Model III. Perhaps everything a la acarte and people can buy what they need to do what they want.

    I'll have to work on it.

    BTW, does anyone have any dead Model IV keyboards?

    I need to buy some keycaps, some of the ones on the two working keyboards I have are missing most of the letter on them.

    Thanks.

    Which key caps do you need and for which keyboard ? Maxi-switch, ALPS or membrane?

    I'm guessing it's the membrane one. Looks like a cheap Model M with the plastic "rivets" through the silver backing and fatter springs?

    I supposed I've never run across them because they weren't ever in any of the Model IVs that I had worked on. Why would someone build something like that (the same thing I said to myself when I opened up the first "riveted" Lenovo keyboard I worked on)? Speaking of Lenovo, I have a 1391401 Model M I should put on my site, now that it's working.

    To answer your other question, I need 2 each of the E, S, D & C keycaps and 1 each of the R, N, A, F, T, I, J and L keycaps. There must be a hell of a lot of dead Model IV membrane keyboards laying around.

    Speaking of Model IVs, I've started putting some stuff up on my site in the Computer Hardware/Tandy section. Most of it shows up on the Home Page as well.

    Thanks for any assist you can give me, Ian.

    Are 128K upgrade kits still available anywhere?

    Well, I have the GALs to make up chip U72 for the NGA type Model IV computer (which is why I wanted to know if there were any 128K badges made up) coming. The chips should be here this Friday and I'll burn a couple and test them for 48 hours, using the 1985 version of Tandy diagnostics, in a 128K M4 to make sure they work right.

    If they pass the tests, I'll start selling the GALs and a set of 8 x 64K x 1 chips as a kit.

    I need three badges if anyone makes any.
