TI-99/4A Ethernet redo

So, Ethernet on TI-99/4A is working nice. DSR got big so had to redo IP stack. 80 column much better for TI web browser development but wish was faster and not so limited. PNG and GIF decoding is slow too. How to speed up...

Video Changes

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.
