I'm thinking about doing a software project for the FinalGROM basically replacing the existing software part, while keeping the existing hardware specs. However the things I have in mind probably will require some more memory (both RAM and flash). Not a hardware guy, so here's my question: Can the Atmel 1284P be used as a pin and voltage compatible drop-in replacement for the 328P? Any ideas? Has this been done before? With the 1284P (haven't check all specs yet) it might be possible to use the FatFS module instread of the Petit FatFs module. That one would allow you to for example create new files on the SD card (which is not possible with Petit FatFS). Obviously you would need the supporting software code to go with it, both on Atmel and on TI side.

That is so cool. Wish I could have been there back in the days. Was there a special cobol program compilation step required to optimize for the TenX? Or did it run out of the box?

Got myself an evercade VS. Fake retro, but it allows me to play Sydney Hunter. Good enough for me. The Collectorvision Phoenix is basically unobtainium, at least in Europe.

@AsmusrFramerate is great, maxing out. But I guess I'm not a great candidate to test because my 12900K intel PC is overpowered and it takes a bunch of stuff to slow it down. Having said that, there's a way to do that though (independent of the JS99er version). The bigger the log file gets, the slower it gets in the end. This is then when it starts to behave sluggish. So there's 2 topics that help getting the log to get very big: 1) The periodic framerate display, 2) The disk I/O messages in the log. This makes it especially noticeable when reading/writing large files, e.g. > 100KB Executing DSR routine for DSK1, PAB in >0A60. DSK1.INVADERS: Input, Sequential, Display, Variable, 80 Op-code 2: READ Returned error code: 0 To fix that I have a local js99er version that has the possibility to turn both messages off.

You might want to follow the same approach I did (or perhaps press CTRL-F5 as @Asmusr) proposed.

Works again. I first tried incognito mode and that one was ok. I then checked all cookies and local storage and removed everything in there, but no luck. At the end I just cleared the browser cache and that was the solution. FWIW I thought it had to do with the websocket connection to my tipi, but I had already reset all there. Using the websocket with my tipi was one of the last things I used in my previous browsing session. But again might be unrelated.

Something is wrong with the 9.7.0 version of js99er.net on google chrome. The emulator doesn't really starts and sticks at frame 0. Works fine on Firefox and Edge. Tested with latest Chrome versions Version 120.0.6099.130 (Official Build) (64-bit)

Would like to use the new DSRLNK replacing my own version in Stevie that was based on Paolo’s work. Will not be able to do that soon, but I do have it added to my list of todo items. If I remember correctly I had to change some of the registers to make it work with spectra2 (which is the library that Stevie is based on). So my question is, if necessary, if it would be possible to change register usage with some proper equates on my end. Anyway, excellent work Lee!

If someone has a picture of the card available, perhaps it can be posted here? 😃

Have to ask. What is a GPIB card?

Works great! Thanks for the quick fix 🙂

I created a 2880 sectors disk that I cannot seem to use in js99er. When loading the disk the browser seems to freeze and cannot recover. FWIW, the disk does work properly in classic99 Here's the disk image: SOURCES.dsk

Unfortunately progress is slow. I know it’s a lame excuse but work has been a killer this year and is eating most of my spare time and energy. Goal is to have a new Stevie version out the latest by the end of the year though.

First of all I like to thank @Albert for hosting our TI-99/4a forum for so many years now. Heck, I remember when I asked Al if we could be part here. He said sure, but you do have to find a few others TI-99’ers to join. 😁 Look how big the place has become. It’s just amazing. Working for a corporate company for many years myself, I can understand the concerns and to be honest I’m also a little biased. But in the end it boils down to trust. Perhaps some things will change in the long run. Some for the better, some for the worse. No one can predict the future, but honestly my take on it is to stay cool and not to panic. Even if Al would not have done this move, who can guarantee you that Atariage would keep on to exist? Myself I am not in favour of moving to another forum, this will just cause more fragmentation. In the end it’s where the community hangs out, that’s what matters. I feel this is the next step in our communities’ journey and am looking forward seeing how it further develops. Looking from the positive side of things, perhaps good things will come out of this. Myself I would love to see more TI-99/4a homebrew cartridge games with nice packaging and artwork like our colecovision friends have. And not only for games, perhaps as part of community efforts we can get more new hardware to tinker with. Just my 2 cents. retroclouds

To anyone who does not have a HRD4000B, if you haven’t one try to get one. For me it is the most valuable of all PEB cards I have. It’s incredibly stable (thanks @Ksarul) and it has so many features that I even’t have touched on.

I think there some out there that might benefit from it. The ones I see are mainly those that use SAMS. For Stevie having more horsepower would help on doing editor buffer manipulation on large files in memory, e.g. assembly source upper case to lower case, search and replace. So far I haven't looked in using the F18a as accellerator. (In the future I'd see C compiler and assembler)

Might sharing that article or link to it? I’d be interested 😀

Same here. Also own an original Explorer Disk and manual. ok, the manual has seen better times 😀 This is an incredible piece of software with a great manual to go with it.

Here's something I started working on. It's in the early stages. What I have in mind is the possibility to have a file directory while typing part of a file path. Nowadays there are many fast devices like TIPI, HDR, IDE, etc. I would add a toggle to turn off the behaviour for "slow" devices like a floppy drive. So far I'm only using level 3 file I/O but do have to admit that on a floppy drive that is very slow. Anyway when this works, the next step is to implement the file-picker functionality. js99er-20230806155746.webm EDIT: also I'll have the possibility to keep showing the contents of the current directory when entering the file menu.

Thanks Stuart. So I presume that you OCR'ed the PDF to extract the source code, did manual adjustment where OCR failed and started from there? Reason for asking is, because the TI version has file loading/saving support you added? Do you have any plans to release your source code branch or if there are reasons preventing you from doing that? Either way, thanks for pointing to the source PDF. It's much appreciated

I would also be very interested in that. Seeing how the cortex implementation looks like from the inside and what can be learnt from that. In the last 2 years I’ve started collecting as much assembly language source code for the TMS9900 as I can.

Do you have any plans on releasing Vanguard in the future? Is there any source code still available? Sounds like a cool title for the TI-99/4a.

yes, it works fine! It's amazing to be able to navigate in Stevie with only using the mouse pointer in js99er. Thank you so much!

if you do go the SAMS route, will it be limited to 1MB or are you targeting 4MB as well? FWIW classic99 supports up to 32MB. EDIT: oh and just to add. Might be an exception in the round, but do run into the SAMS 1MB limit from time to time with my editor.
