Along this same line... Has there been any more work done on the 1090XL case? I have a friend that has a small machine shop in his garage. Leaves his pickup outside (like me). He has said he wouldn't mind looking at the drawings if someone has them... David 2 Quote Link to comment Share on other sites More sharing options...

David Sadly, I don't think anyone has any blueprints. The best option would be for someone with an actual 1090XL to take every measurement imaginable so that actual blueprints could be made. 1 Quote Link to comment Share on other sites More sharing options...

Looking at the information, in my PBI document, I noticed these notes: ULTIMATE 1 MB $D100 - $D1BE I/O RAM (When enabled.) $D1BF Bank switch register $D1FF Emulated PBI device configuration $D600 - $D7FF I/O RAM (When enabled.) $D800 - $DFFF RAM or OS ROM (When enabled.) What would be cool is... a U1MB and VBXE designed to just sit in the 1090XL so we didn't have to go hacking and making a Cyberpunk looking city inside our machines (though for some people, that's also very fun). Granted, I have no clue if that's even possible. I'm thinking about ordering one now, are the only currently produced cards the 80 column and CX-85 boards? I thought I saw a picture of another one, but not sure what it is. Oh, I see, it's a 320kb memory expansion. Edited March 7 by leech Quote Link to comment Share on other sites More sharing options...

If there is enough interest, more cards will be coming. 🙂 Well, I ordered the full set of 1090xl, ram, cx-85 and 80 column card. I'll see if I can't design a case for it, since that seems to be lacking currently. Then I can prototype it with my 3D printer. If I can create something satisfactory, I will of course post the STLs. But hopefully if someone then takes the model and makes a more proper print or mold, it would be awesome to get a discount. 😀 Ha, maybe I'll throw a little 'Designed by Leech' on the inside, like the A1000 had for their team... 2 1 Quote Link to comment Share on other sites More sharing options...

+Larry Posted March 7 Share Posted March 7 What E: handler is used for the 80-column card? Is it in the 1090 firmware? How is it activated from stock 40-column? Quote Link to comment Share on other sites More sharing options...
kenames99 Posted March 7 Author Share Posted March 7 The E: handler is built into the video card. That is the atari spec. Could always load another from disk or cart but that defeats the purpose. Ken 4 1 Quote Link to comment Share on other sites More sharing options...

I would think an FPGA board stuck in there with some I/O... then get the developers to port cores over to it... or, maybe even use it to recreate other platforms in a card. Ha, the Atari MiSTerXL.

Candle has a PBI version of the U1MB working. But I guess that VBXE would not be possible this way but I don't know enough about it to be sure. 1 Quote Link to comment Share on other sites More sharing options...

+Larry Posted March 8 Share Posted March 8 At this time, what cards are available -- 80-col., 320K ram, and CX85 keypad? Did I miss any? If one uses the 1090, they can't use a hard drive, nor have multiple OS? (Although I would think you could still have internal multiple OS, but the 1090 wouldn't work?)

(Although I would think you could still have internal multiple OS, but the 1090 wouldn't work?) @kenames99 has re-created the composite output 80 column card and the 64k RAM card. (Gerber files are available.) I am working on a card that would upgrade the OS and BASIC. Also sitting in the queue is a FujiNet card, COVOX card, CP/M card, a RAM Disk card, and some others. I have a close re-make of the picture verison of the CP/M card almost completed. Other cards are certainly possible. There is also some discussion about a multi-purpose card with USB I/O. The 1090 should work with multiple internal OS's. Though, it does depend upon how these OS's were implemented. 4 Quote Link to comment Share on other sites More sharing options...

I'm curious if something on the level of a PiStorm style thing could be implemented that simply emulates VBXE / RAPIDUS on a board? These are already emulated via Altirra, right? Or even just emulation cores for a few other things, like a c64. Ha, that would be amusing. 12 hours ago, reifsnyderb said: 1090XL's are breeding. 🙂 Three are leaving the roost today. Beautiful! How much heat do these generate? I noticed on the videos of the original, that the case has vents on top and what looks to be a fan mount on the back. I was thinking it would look cooler for a case designed to look more like the 600xl/800xl. I'm trying to work out in my head how best to make it sturdy and cool looking with a 3d printer... also, wonder if the metal case of the original would get hot, and overall a full plastic may not absorb the heat as much... guess I will find out. 😀 1 Quote Link to comment Share on other sites More sharing options...

The heat sinks can get pretty warm to the touch and the shunt resistors can get uncomfortably hot. Quote Link to comment Share on other sites More sharing options...
+Larry Posted March 8 Share Posted March 8 What apps would work with the 80-column card? And (anyone) how big of a deal would it be to get one of the many word processors or text editors available for the Atari working with the 1090 80-column card? It may not be a killer app, but we need at least one app for it. Do BASICs work well with it? IIRC, some 80-column configurations only allowed 80 characters on a Basic line. The Bit 80 was that way, I think. And what are the dimensions (for those of us who are short on desk space)? Sorry for all the questions, but I think they are "good questions." 1 Quote Link to comment Share on other sites More sharing options...

leech Posted March 8 Share Posted March 8 3 minutes ago, David_P said: Atariwriter does not work yet (I suspect AW80 can be patched...) I was wondering about that, as it seems there is the specific 80 column version. Does @flashjazzcat word processor work on it? I thought one of the videos I saw on YouTube showed a specific version of AtariWriter would work on it (at least the original 80 column card.)

reifsnyderb Posted March 8 Share Posted March 8 The 80 column card will do text like the XEP-80. I just tested a line of BASIC code, in Alterra BASIC, with the 80 column card and I was just able to enter a 150 character line without error. Live screen editing works as well. 🙂 After double-checking with Mapping the Atari, I'd say that the biggest concern will be that the long lines will allow for buffer overflows into page 6 memory. The 1090XL, with the cable, is around 12 inches deep and a little over 8 inches wide. The height will be around 4 inches for the smaller (1091 size) cards and around 7 inches for the full height cards. You may want a little more height for a future case. I was thinking some about this and the old computer tables would have been fine as they had the TV or monitor on a shelf above desk level. So, for a 1980's setup, I don't think it would have been an issue. For a modern setup, that is another story. 2 1 Quote Link to comment Share on other sites More sharing options...
drac030 Posted March 8 Share Posted March 8 As far as I can tell from the emulation, the worst problem with the 80-column board is that its firmware is utter cra.... very alpha, that is. Without thourough rewrite there is little hope that it would work reliably on broader scale. Quote Link to comment Share on other sites More sharing options...

The firmware on the HDMI 80 column card is rather simple and based on the same firmware as Atari's 80 column card then combined with the XEP-80 driver with changes for the 1090XL environment. All it really does it re-direct E: and S: then send the data to the Raspberry Pi Pico. Here's the firmware: xep80.s Updates and improvements are welcome! 🙂 Edited March 8 by reifsnyderb 5 Quote Link to comment Share on other sites More sharing options...
