Brian, I noticed you have a new DB25 PCB on Osh Park. I suspect the whole TPDD cable was intended to take a TTL level floppy drive and bring it to a standard RS-232 level. I'm wondering if that same PCB could be used with one of the inexpensive TTL level FTDI USB to serial converters to create

[M100] 15 Bytes of RAM

I'm working on a little piece of code that loads some stored code from the option ROM on my NEC 8201a. I was able to tweak Gary Weber's disassembler code to get the bytes from the option ROM. But here is the problem. The code I am pulling down runs in the ALT LDC memory space. Alt LCD is 320 bytes

Re: [M100] Unable to Load TEENY to MT

Teeny can also be injected from mComm. It's quite a bit smaller too so it loads faster. I'm not sure why that error would be coming up with TS-DOS. Did you use the command "RUN COM:98N1E" from Basic? The dos injector uses xon/xoff so the flow control lines don't matter when loading. On Tue, Jan

Re: [M100] Unable to Load TEENY to MT

Since you are using Windows 7, mComm for Windows has the ability to push TEENY or TS-DOS to a Model-T. On Tue, Jan 22, 2019, at 3:03 PM, Greg Swallow wrote: > All, > > Got a Rex from arcadeshopper. Need to flash it and am trying to load > TEENY. Not working. Attached MT to a Portege running

Re: [M100] Very stupid question?

Brian, I have not tried the cables you mentioned so if they work that's great to have off the shelf solutions. The problem that I ran into was that when the dcd was tied to dtr/dsr my Tandy 200 would not work. My Tandy 102 and NEC 8201a were perfectly happy with that setup though. I'm not sure

Re: [M100] Very stupid question?

Yes, that's a copy and paste from the manual. I've made quite a few of these cables over the past few years. I always had difficulty getting a store bought cable that worked. > > That looks like a copy/paste from the cable.html file of the mComm > documentation. > My next try will be to check

Re: [M100] Very stupid question?

There will always be slight contrast change when using the serial port since you draw a little more power. But if you see significant contrast change, you have a problem. This happens to me, no matter what machine I am using, when I forget to put the little NULL modem adapter between my cable and

[M100] BASIC/OPTROM Question

Quick question which I hope somebody knows. Is there a way in BASIC to read a byte from an OPTROM? Similar to doing a peek to the main rom? Or is this strictly something that has to be done with assembler? Kurt

[M100] NEC Personal Application Kit

For those interested, I was able to get a copy of the NEC Personal Application Kit tape and pull all the files off. I put everything in a ZIP file. This includes the barcode drivers that somebody was looking for earlier this year. The BASIC files are saved as both ASCII and Tokenized BASIC. Enjoy.

Re: [M100] Fwd: mComm for Android

Tom, That error is usually from a failure to connect. What version of mComm are you running? I have not played with the Bluetooth connections for quite some time so I will need to go and look at my notes. Some things to check. 1) Are you running the same version of mComm on the S9 as on the S5?
