7800Basic nub here. I'm enjoying 7800Basic, but there are some quirks I'm not sure about, I often get a BIN size errors that seem to be caused by syntax or logic errors, but it gives me no clue to where the issue is (line number etc). Is this standard behavior? Because its very time consuming to find these sometimes. My second issue is when I complete my homebrew I would like to produce a cartridge for it, whats the best way to go about this? I've have read cannibalising a real 7800 cartridge is an option, but cant I print a PCB and use a 3D printer to print the case?

Cool thanks. Another question does 7800Basic allow for nested GOSUBs? ie: main_loop gosub drawplayer goto main_loop drawplayer if playerdead then gosub deadplayer return deadplayer lives=lives-1 return

I haven't come across how to detect collisions between sprites and tiles is this not possible? [EDIT: I did find this]

Im not able to get my 1088XEL running, is someone able to to have a look at it? Happy to send it to you.

Havent had much time to look into it, but I did check the orientation of the CPU and Antic and both are correct ( pin 1 facing the edge of the board) . I might try re-soldering their sockets in case I have a bad one or two connections there.

Oh, well that's potentially exciting, will do, thanks!

I soldered in the the replacement LED's, and they light up as expected, 5v good, power on lights up, but i get no boot, the lights on the BOB board flicker on power up so I guess I have a short somewhere.

Th The thing is I did read your account and was determined to not make the same mistake, but I guess my dyslexia kicked in when it came to fitting them I have to wait for replacement LED's now...

Thanks for that! Every day is a school day!

Hang on, so the square pads for LEDs are negative,but elsewhere on the board its positive?

It turned out my DIGIKEY 5v/2amp was working fine, but I get no 5v LED, what would I check next?

Thanks I have identified a local power adapter https://www.jaycar.co.nz/27w-3-12vdc-switchmode-plugpack-with-usb-outlet/p/MP3316

I understand a 2A USB Power Adapter will work?

Finally got the 1088XEL assembled but it turns out my 5V Adapter from Digikey was DOA, I'll source one locally, does the 1088XEL require 2A? I cant seem locate a match. I tried a 5v 1A I have, but I get no power on LED, just flickering LED son the USB/SIO board. :/ Thanks in advance.

Add RGB DB9 next to DVI pop-out, I also indented around the USB port.

For those that were following my case just an update that I 3d Printed a draft of the back panel to ensure the ports aligned and that the pop out panels worked.... and it did, perfectly! The USB connector was 100% that was the big test, the pop outs worked as designed, and I placed my RGB connector from the Sophia in one of the spare DB9 pop-outs, holes aligned too! Im adding three DB9s now in case someone wants 4 joystick ports and the Sophia running. Just waiting on some new printer parts to trial a print of the whole case.

Thanks awesome.

Looking at this image below it looks like I nailed it, where would the best spot be to get the audio for the RGB cable that came with the Sophia? A Pin from the Aux Audio? If so which Pin? Or somewhere closer to the RGB header? Thanks Chaps.

Hi, can someone confirm I have crimped my Sophia cable correctly, I'm assuming pin one is audio to the RGB connector? Pin 10 is not connected? Still waiting on a back order from Digi key for 3 final components...

good old Blutack, great suggestion!

Regarding the U1MB Installation I saw Jazzcat's removal of the horizontal pins for the U1MB , but I would like to be 100% about the steps, I assume its: Remove the horizontal pins on the U1MB Soldering male pins to the U1MB Fitting the headers on to these before fitting the assembly into place (to ensure correct position) Soldering the headers Don't upgrade U1MB to 1088XEL Firmware until all proved working. (URL to the latest version of this?) Only waiting on the UAV and three components now to complete my build. Bought a 3D printer to prototype my case. Thanks chaps!

Hi Michael, How does the VGATE option work? Do I need to jumper J19 to activate it? Cheers!

Hi, can someone let me know what that plug is called used on the Sofia that goes to the the RGB header? Would like to buy one to crimp a new cable for the 1088XEL, Ta

Looks like it has eyes and a mouth now.... :/

O for Awesome Ok. ... thats a NZ reference BTW one of our shining moments on TV
