Hi, Crock I'm very interested in your experience with PetVet. I will have to manage to prepare "non standard" configurations (IE: RAM only or ROM only) and documentation is really minimal. The first question I have is about "programming" mode : Can it stay in 6502 pet's socket or does it absolutely need to be removed ? [from what I understand from your post, it can stay in the socket, what is, I think, really better] ==> Programming jumper might be replaced by a simple inverter switch "Extract" from documentation : Jumper settings and ROM contents can be customized by reprogramming the flash memory on the PETvet’s microcontroller. To reprogram the PETvet, first remove the PETvet from the PET motherboard. Move the programming jumper to the left into the “Program” setting as shown: Connect the PETvet to a terminal, 38400 baud N81. Connect the PETvet to a 5v power source and a message will appear on your terminal indicating that the PETvet is in programming mode. Start an XMODEM transfer in your terminal program and begin sending the binary that you want to reprogram the PETvet with. Move the programming jumper back to “Run” mode, and after a second or two you will see the XMODEM transfer begin. When the transfer is complete, your PETvet is reprogrammed and ready to go. More details on everything coming soon.. ... even the complete 1/2/3 jumpers purpose are quite unclear (from what I understand, it allows selecting 1 configuration over 3 preprogrammed setups ... but a such scheme should allow 8 setups ?? Also, why are those jumpers located all around the board ?) Other "strange" things on the board are : - 2*3 pin connector next to the DB9 - 2*3 pads next to the RAM chip - 4 groups of 2*1 pads "all around" the board Tous vos emails en 1 clic avec l'application SFR Mail sur iPhone et Android - En savoir plus. ======================================== Message du : 14/11/2013 17:28 De : firstname.lastname@example.org A : email@example.com Copie à : Sujet : Re: PetDisk (was Re: Re: 1541 to 2031 adapter (was no subject)) I used the PetVet quite a bit last year, including defining & building your own ROM images for upload over the serial port. I also made a diagnostic ROM specifically for the PetVET which utilises the banking facilities to only replace the top 1k of ROM, allowing it to test the machine RAM and checksum the ROM's. All this was was over a year ago now and I am appallingly bad at writing down what I did, but I still have all my scripts and code. Mike provided me with some great help. I seem to remember there was a gotcha with reloading the firmware - I think you have to initiate the xmodem transfer in 'program' mode, wait for it to pause and flick it back into 'run' mode - all while plugged into a powered on PET - which was fun. If you get stuck, ping me and maybe I might write something down this time. :-) Rob On 14/11/2013 17:13, firstname.lastname@example.org wrote: > I've finally received my PetDisk & PetVet last week ....
