Not many people are using it so with limited test time it gets left out of the test matrix. Looks like the client has some dependency on latitude that Laddiealpha and dlplus give that desklink and a real TPDD do not. Maybe max request length? -- John. On Wed, Apr 13, 2022, 3:15 PM Cedric Amand

[M100] NEC 8201 LCD

2022-04-13 Thread Robert J. Hutchins
Question: My NEC 8201 has a defect, one half column is always lit up. I disassembled it, cleaned the strips but no change. Is this usually a screen memory defect? If anyone has a Model 100 LCD, in good shape I would like to purchase it. Thank you Robert J. Hutchins

I never test with that. Only LaddieAlpha. would be better to cover every possible TPDD, but... I don't have that kind of time! On Wed, Apr 13, 2022 at 6:15 PM Cedric Amand wrote: > Yes, > Bad choice ? > > > > Le 2022-04-14 00:14, John R. Hogerhuis a écrit : > > " TPDD emulator run on MSDOS"

Hey everyone, Trying to make use of my second hand REX, I've managed to have a TPDD emulator run on MSDOS and was able to load a couple of ROMs (mforth & MP100 )/ This is REX#2.0 Each loading ends up with the message CRC error in 57600 Y which is overwritten by an "Ok" which actually gives OkC e

Hello Brian, First of all, again thanks for taking the time to answer me in so much detail. You're right about the confusion about TPDD client and emulators, I actually just did the mistake, installing on my msdos computer what is clearly an tpdd client, not an emulator. By the way here's my set

Yes. In fact a real tpdd doesn't even work for this. It's supposed to in theory even though it's so inconvenient to rig up that no one would ever actually do it that way, but I had reason to actually try it and the rex setup util doesn't work with either a real TPDD1 or TPDD2. Anyway yes you

Okay, What's you're saying is that with the serial link still in place (for the initial serial transfer), i can simply switch software in my modern pc (on the other end of the serial) instead of going into the extra trouble to actually make a real TPDD floppy do the job :) Well actually i'll try

Hi Cedric, To transfer XX.DO programs into the M100 without a DOS on the laptop, you can use a serial transfer method by connecting the M100 via serial to a PC and using a terminal program to send the text. When you are actually running the upgrade utility, you need to replace the PC-terminal

Thanks a lot Stephen; This is all probably easier for the original owner, having to "onboard" not knowing the history of the device is difficult. What was troubling to me is the releases notes that made me believe a version I did not have (4.x) solved the Y2K problem, or a rom patch. Given the f

Hi everyone, As Stephen already knows, I bought a M100 from someone would did put a REX# in it, and i'm trying to get a complete understanding of it. I have many questions but let's start with a few I see versions of the rex from 4.5 to 4.9, and other versions saying V2.0 or v2.1 Do some numbers
