  1. --- Update after 30 days --- So, I set a time limit on resolving this issue. There are not enough Geneve users to sink a ton of time into this. The problem at hand was that at the low level, sending data to the TIPI on a stock Geneve was not working. This was fixed with a CPLD update on the TIPI. The update can be applied by anyone, instructions to do so are on the TIPI wiki: https://github.com/jedimatt42/tipi/wiki/CPLD-Programming-With-PI. This shows TIPI to function in GPL under ROMPAGE mode. The storage system is not supported by MDOS. Further, there are errors receiving data from TIPI when using the 'recvmsg' function in the TIPI ROM from MDOS mode. This seems to only happen when the destination memory buffer is external to the Geneve in the PEB. That points to a hardware flaw in TIPI still. But value vs. time prohibits further hardware investigation on my part. Some experiments in software workarounds are still pending. Probably the vrecvmsg routine in TIPI ROM will work just fine, as it reads into VDP memory. Again this is only a problem if you are addressing external CPU ram in the PEB, such as a MEMEX card or a Myarc 512k card modified for the Geneve. [email protected] --- Original Post --- Ok, so Tim has put in my hands a Geneve that reproduces the problem with TIPI. I've built a test cartridge that exercises the TIPI in GPL/ROMPAGE mode, and a corresponding python script. What we see is that I cannot write to the 8 bit latches in the CPLD at 0x5FFD and 0x5FFF. This is all I know so far, all the rest of TIPI works... reading from the latches set by the PI work fine, reading the ROM works fine, the crubits work fine. --- I've been sitting on this for a while. but I have a lot of other things I want to do in my hobby life... So... For the next 30 days, this will be my HOBBY priority. and if I do not have a solution by then, I am done. The only interest I have in getting it to work on other peoples' Geneves is gaining a little bit of knowledge. But I need to make a good effort, and then admit defeat and move on, or rejoice in success! ( I am hoping for the latter ) I don't build TIPIs... I won't build TIPIs. So if the outcome requires physical changes, you'll all have to find someone to build them. --- So, if you want this to work, now is a good time for you to learn how to read verilog, and assembly, and pester me. Beery has been feeding me clues for a while... Given some of what he has fed me, and the lack of information out there, I'm going to start back at the prototyping process to figure out how to latch 8 bits in the DSR address space on write. Seems simple enough... But I have to pretend I don't know how to do it on a 4A or I'm trapped in the loop. --- Interesting thing I read last night in the 9995 datasheet... the WE and CRU_CLK signal are the same pin...

  2. I'm creating a poll, hopefully, to determine how many Geneve users using original hardware or an emulator, are on this Forum. Beery
  3. So, I have a Geneve. A few folks recently have Geneves that are in various states of repair. A handful of you all have working Geneves. --- Looking around, I see lots of software development tools and proofs of concept, but no applications... Growing up, my father used his Geneve for 80 column multiplan... That was really it. That and printing. He didn't game... He managed a mailing list, which was a TI Writer or Multiplan file with peoples names and addresses organized for printing on avery labels for things like 'Christmas letter' or the user-group's newsletter mailing. I used Myart to turn my 'C' at best homework into something that wow'ed the teachers into an 'A', or wrote little GPL snippets that crashed it. I know there was some ABASIC stuff written, but I don't know what any of it was called. In order to find anything on WHTECH you already have to know what it is. I'd love to make something like Vorticon's Gameshelf, but Geneve specific, and not limited to Games. So, I'd like to learn... what is out there for the Geneve? What are your favorite Geneve specific programs? What 4A programs were greatly enhanced by running on the Geneve (even if just for the speed)? And yes, I'd like to include those tech demos and dev tools as well. [email protected]
  4. I find binaries for the v1.00 Geneve ROM, and genmod variant. But do we have the source code for it? I'm surprised that isn't part of the source distribution for MDOS... I'd love to see what's actually in there. Gain some understanding... Or maybe it inside one of those .ark files? [email protected]
