I have to agree that homebrew development is frustrating with this thing as programming an oldschool eprom takes some time. And emulators are not as good as I thought. Even ParaJVE differs a lot when it comes to the drift and brightness simulation.Slamyhttps://www.blogger.com/profile/06199660583857443750noreply@blogger.comtag:blogger.com,1999:blog-8399067511826858944.post-2768402932781596672013-12-16T12:12:38.984+01:002013-12-16T12:12:38.984+01:00The VecMulti is still available from Richard H unc...The VecMulti is still available from Richard H uncased. He will sell you the circuit board without case; it comes with the SD card and free shipping for the same price as the cased VecMulti. You can PM him on the AtariAge forum for ordering info. I just bought one from him in Nov. 2013, and it's very easy to use and house in a standard Vectrex cartridge. I used an old Heads Up Action Soccer cart.Katohttps://www.blogger.com/profile/07322515734563284202noreply@blogger.comtag:blogger.com,1999:blog-8399067511826858944.post-25366119027894878322013-06-17T13:22:30.858+02:002013-06-17T13:22:30.858+02:00Wow.

He said the same as you do here and has given me a few advices about electrical things I should care about. Still he hasn't said anything about the future of the VecMulti.<br /><br />The source code of Alex Hubert is actually the one used by "Thrust" as It turned out.Slamyhttps://www.blogger.com/profile/06199660583857443750noreply@blogger.comtag:blogger.com,1999:blog-8399067511826858944.post-62349753088151685482013-06-16T23:14:41.706+02:002013-06-16T23:14:41.706+02:00hmm that's strange, just replied but it didn&#...hmm that's strange, just replied but it didn't gey published. The 1-Wire EEPROM for YASI is on I/O line (PB6) of the Vectrex cartrdige slot. I believe this code is used by other homebrewers too.<br />For more info you can see the source code made by Alex Hubert the author on his website at http://www.herbs64.plus.com/files/vec1wire.zipVectrexMad!https://www.blogger.com/profile/06701815506101647386noreply@blogger.comtag:blogger.com,1999:blog-8399067511826858944.post-13236813955357378312013-06-16T23:09:32.379+02:002013-06-16T23:09:32.379+02:00Johannes at http://madtronix.com does not respond ...Johannes at http://madtronix.com does not respond to emails.

I asked him for schematics of the VecMulti as I wanted to know how he has solved the problem of communication between the microcontroller and the sram as the vectrex also has access to it.<br />Maybe I wanted to much. Besides I've evaluated the sourcecode of "Thrust" which is opensource. This game uses a 1-Wire EEPROM for savings. I've included it in the design a few hours after writing this blogentry.<br />I hope that Y.A.S.I and Protector use also this solution.<br /><br />But thank you. You are right. I need to ask different people. And maybe after these months Richard H. is more cooperative. :-)<br />Slamyhttps://www.blogger.com/profile/06199660583857443750noreply@blogger.comtag:blogger.com,1999:blog-8399067511826858944.post-3859766800219974542013-06-16T16:16:36.348+02:002013-06-16T16:16:36.348+02:00You might also contact Johannes at http://madtroni...You might also contact Johannes at http://madtronix.com.Vectrexerhttps://www.blogger.com/profile/14607378237045109802noreply@blogger.comtag:blogger.com,1999:blog-8399067511826858944.post-69927115302307749092013-06-16T15:56:05.579+02:002013-06-16T15:56:05.579+02:00You may want to contact Richard H over at Vectrex....You may want to contact Richard H over at Vectrex.biz for some assistance on the memory backup.
