Had most interesting time. Was thinking about newtechnology. Wanted to connect TI to new LED backlight LCD monitor. Prototype hardware now reworked to emulate V9938/V9958/V9918 hardware. Circuit with VGA support working well to create crystal clear video on 21" LCD widescreen. Ever see Mechatronics 80 column device?
So now I able to use 80 column TI on LCD VGA/DVI :)( Need to locate some programs that might display GIF or other graphics formats. Oh, 40 column look quite clear now too. Bet you wonder how screenshots from early blog were so clear? Now you know secret!
Must finish device and integrate DSRs now. More to do, more to do. Always.

Fixed it!
Hah. Fixed printer output took review of code forever. Still slow progress. Anyone out there following? Forgotten Realms for sure

Slow progress
Work been slow on new features. Has it been 3 month since last post? Oh dear. Will get back to work soon for anyone following.

Extended BASIC
Still having hardware problems but was able to test emulation of Myarc 512K memory using device. Myarc Extended BASIC II does nice job with this scheme. Can emulate RAMdisk and print spooler but printing not going output. Maybe CRU conflict? More work to do! Might stick to AMS RAM emulation for now.

TI Yahoo Group
Today I came across a TI group called TI Yahoo group. It looked like a fun place to join. But I start reading recent comments and see bitter people arguing about community. Why people argue about 30 year old technology is silly. Do people have nothing better to do? I do and that is why I not join that community. Sorry I ever found link to THAT one.
Made progress on TCPMail and TCPFTP programs. Using AMS memory for functions nice.
Added DSR routine to use Archiver files without need for archiver. Uses AMS RAM for file buffers and make use of special code. Not lot of use for it yet but will think of ideas.

TI-99/8
Almost forgot to record that today was successful test of TI-99/8 with TITCP. Faster speed of this computer with 9995 able to download some things over internet with TI-FTP much smoother. Had to disable AMS memory, 99/8 locked up when enabling it.
Joysticks
Joystick problem fixed qnd added toggle for TI joysticks or regular, Ataristyle joysticks.
RAMdisk is back to working with modified Horizon ROS. Joystick fix must have fixed RAMdisk problem, cru related. Maybe program to dump RAMdisk to flash would be good idea to eliminate dependency on battery?

Some hardware
Time for description of hardware
Device has been developing for a long time. I am using the TI-99/4A home computer. The device has three main capability:
1. 10/100 ethernet connection
2. AMS memory card emulation with 32K and super cart
3. disk and hard disk emulation with SD memory
Device is connected to cartridge port to allow cartridge dumping directly into the storage device. Also makes handy for editor assembler and extended basic cartridge or any cartridge emulation with selection.
The main device plug into the side expansion port. A speech synthesiser cannot be used because of limitations of my own knowledge. (Speech is a useless feature to me so not a worry). The joystick and cassette ports are used for extra CRU handling and data transfer. Serial connection available by coupling joystick and cassette also possible but a bit slower than regular RS232.
Ethernet lets me do FTP and file transfers quicker than RS232 so not a big concern.
I did not like swapping all of my diskette drives so added a hard drive emulation and disk emulation with SD flash. 4GB is ok to use but using the similar techniques of Myarc HFDC and using same limitations to be compatible. The DSR can select partitions for you to use with your programs.
AMS memory emulation is nice for building large programs that take advantage of the TI hardware. C compiler make it easy to port some software to TI.
Need to borrow camera to take some pictures of my hardware connections. Broke my camera with TI Peripheral box cover few month ago accidentally. Put cover corner down smashed lenz with heavy weight of cover. Poor camera rest in peace.
Nice having holiday time to try to document this work. Add bypass to joystick port still needed to play games. DSR bug really causing grief last month.

Screen shot
Screen of active DSR configuration of device project.
Easy to be configuring this device now. Load interrupt come in handy to interrupt the hardware and make changes on fly. Nice having all hardware together :)
First Post - finally
Finally to use blog is good idea. yay :)
Able to connect TI to video capture for some screen shots. Pictures not very clear with TI Monitor but look nice with directly connection.
