GDMike Posted April 9, 2022 Share Posted April 9, 2022 (edited) Unrelated, but could you also make a new io board for the PEB? Once you get inside the box they are really easy to remove, just screws and 4 power wires. But these sockets are getting worn out on my PEB. Unless you are working on something related to this, maybe a PS and case? Could you imagine, a new black exciting looking PEB? I'll do the survey now. Thx Edited April 9, 2022 by GDMike Quote Link to comment Share on other sites More sharing options...
wierd_w Posted April 9, 2022 Share Posted April 9, 2022 (edited) I thought the PEB side WAS part of this ensemble? https://atariage.com/forums/topic/323858-838-io-card-flex-interface-card-replacement/?do=findComment&comment=4969163 Edited April 9, 2022 by wierd_w Quote Link to comment Share on other sites More sharing options...

But from what I gathered was just a card for extending the cable to the ti.?? Quote Link to comment Share on other sites More sharing options...
wierd_w Posted April 9, 2022 Share Posted April 9, 2022 Linked post has the SHIFT838/IO board (for the PEB), along with the matching sidecar board, and the mating 32k board. 1 Quote Link to comment Share on other sites More sharing options...

Right. I was hoping to one day try replacing my io MAIN board. Quote Link to comment Share on other sites More sharing options...
wierd_w Posted April 9, 2022 Share Posted April 9, 2022 I have considered designing a replacement PEB system, and think having these available would greatly simplify matters. (The insides of the PEB are basically just a PSU (with somewhat odd choices of voltages), and a dumb backplane. The magic part is the IO board and sidecar interface, which this project supplies) All I would need to make, is a backplane that accepts an ATX power supply, and has some beefy boost DC-DC transformers to supply the needed voltages from the ATX-motherboard rails-- the rest is just enclosure design. Not that I ever expect to get further than just brainstorming mind, but this is the majority of any hard work for a PEB replacement project. 1 Quote Link to comment Share on other sites More sharing options...
GDMike Posted April 9, 2022 Share Posted April 9, 2022 (edited) My phone acting up again... but I wanted to reply, and say..we might need to plug in another PEB from a master if we keep making cards.. what cards are a need at this point.. TIPI, speech? Interface, I still use floppy controller too 16 minutes ago, wierd_w said: Brainstorming Edited April 9, 2022 by GDMike Quote Link to comment Share on other sites More sharing options...
wierd_w Posted April 9, 2022 Share Posted April 9, 2022 The issue I see with that, is that you will have signals that exceed the clock time allowed. (Bus transceiver delays compounded, between the replacement FlexIO, and the bridge connecting the two backplanes, both of which would need the transceivers) It would be better just to offer a larger peb box. Maybe one that is double sided. (A tower design, with a central board, and card slots mounted on both sides). 1 Quote Link to comment Share on other sites More sharing options...
GDMike Posted April 9, 2022 Share Posted April 9, 2022 Right that's why I brought up post#76. I think it's Time. I've got an rs232 I can't add because I've got an SDD sound card and my tipi (internal) takes two spaces because I don't want anything hitting the wires and fan of my pi I've added on to it.

GDMike Posted April 9, 2022 Share Posted April 9, 2022 (edited) Oh.. but I don't like the tower version because I put my monitor on top. ? Edited April 9, 2022 by GDMike Quote Link to comment Share on other sites More sharing options...
webdeck Posted April 9, 2022 Share Posted April 9, 2022 It's a little late in the game for me to be tossing out ideas, but this does seem like the ideal place to add a reset switch and a load interrupt switch for the console, rather than modding the console or a speech synth.

wierd_w Posted April 11, 2022 Share Posted April 11, 2022 I would personally make a sidecar for that, and put it just before this one. 1 Quote Link to comment Share on other sites More sharing options...

After some search I found it. This does not appear to be a viable solution without possible messing something up on our aging machines.

+jedimatt42 Posted April 11, 2022 Share Posted April 11, 2022 Most users today have a FinalGROM99, which provides an external reset via the cartridge port. 3 Quote Link to comment Share on other sites More sharing options...

Right - excellent point about the reset button already being right there on the FinalGROM99, right in front of my face. 4 Quote Link to comment Share on other sites More sharing options...

+retroclouds Posted April 13, 2022 Share Posted April 13, 2022 That's a cool demo and very nice project you have going there. I would like to make a small suggestion regarding the 3D printed case; I would not print the "32K" badge on there, but keep it more general. What if at a later time, you e.g. decide to make a SAMS card that fits into that formfactor. That happened to me with the TIPI side printed case, where it says 32K, but I have a 1MB sams in there and don't feel getting/printing a new case because of the logo. 3 Quote Link to comment Share on other sites More sharing options...

Shift838 Posted April 13, 2022 Author Share Posted April 13, 2022 So, I am thinking of selling the 3 Revisions A I currently have. I have 2 built that I am using and enough parts to build another 3 that can include: 838-IO Plus PEB card 838-IO Plus Sideport card (both above are needed to function) 838-32k Optional Expansion I also have 4.5 foot cables ready and of course can print a 3D printed case. which takes about 9 hours! contact me via PM to discuss pricing and options you want, otherwise they will be added to my store.. 1 Quote Link to comment Share on other sites More sharing options...
wierd_w Posted April 14, 2022 Share Posted April 14, 2022 I am beautifying the now-functional base case design. I will make the suggested changes. Quote Link to comment Share on other sites More sharing options...
