Thanks for that distinction, makes total sense as well because for Deluxe Paint I renamed "DPAINT.TOS" to "DPAINT.PRG" to have it launch inside the AUTO folder.

Thank you, this was exactly the info I needed! I didn't have an ST 'back in the day' so I'm learning as an Atari Newb now

Hello, I have to create some disks for an environment where the user expects the program on the disk to start automagically without user intervention. I'm using the "AUTO FOLDER" method where the ST will automatically launch the .PRG in this folder. The three programs I'm preparing are: Deluxe Paint v1.0 - after putting the paint PRG in the folder this worked perfectly (this one is OK) Atari Music Maker v1.0 - when I put the music maker PRG in the auto folder it fails to load. If I then manually launch it, it launches successfully. I tried moving all the files into the auto folder but still no joy. Omikron Basic v3.0.3 - when I put the PRG in the auto folder, it loads but without mouse support in the basic editor. Any help / tips appreciated to auto launch #2 and #3 with mouse support. Are there other better "auto" methods I should be looking into, and are there additional config files that can be put in the AUTO folder to enable mouse support? Thanks!

Did you find out anything else about this board? I just opened up an Atari 520ST and it has the same exact board in there! 😮 Seems this board needs to be re-seated often 🤔 Mine has the battery & dallas clock chip on there. I wonder if I can unearth the software, or does the clock work with the OS native? Guess I'll find out. Atari st tech-specialities Co houston, tx 520A r2.11

Arkanoid is a good simple one to test with as well

Well no replies, so either the BOM is ok, or no-one had time to look at it 😅

Hello, I ordered some FujiNet FN32ROV-1.6 / UID US000651 PCB's and a stencil from JLCPCB awhile back and I'm finally getting around to attempt building one. This is my first Fujinet build (and first SMD stencil build 😮) so I thought I'd post up my BOM before ordering to see if anyone spots any obvious errors. I did my best to match up the parts and got some help on the github as well. If you can review and give feedback, would be much appreciated: https://octopart.com/bom-tool/wwdTgpTK p.s. github says "SMD pads for passives are 0402 but you can use 0603 sized passives on them" so the BOM sources 0603.

Anyone have a copy of MASH9.BIN from this post? I'm putting together a FlashROM99 SD Card with as many voice enabled games as I can. Sofar I have: Alpine Buck Rogers Demon Fathom Microsurgeon Moon Mine Parsec Star Trek

BTW @Ksarul there's a project in progress here: TI/99 4a clone | Vintage Computer Federation Forums Not a drop-in replacement, but clone.

Ok nevermind, I found a pin on the back I forgot to solder 🙄 and it's working now with default jumpers, $6000 & $A000 concatenated in that order. p.s. i'm attaching the PCB gerber as well in case it's useful for someone Vic16K-G_P_2022-10-04-Gerber-GOOD.zip

Still not working with the capacitor. I'm starting to wonder now if my PCB is correct. I'll do some tracing on it.

Hello, I’m attempting to create / re-create a VIC-20 cartridge of the game “Sky Blazer” by Broderbund. I have two working CRT files (confirmed working by loading them into Vice, attaching the 8KB Images at $6000 and $A000 respectively.) I had some 16K ROM Cartridge PCB’s made using the Eagle files from this thread and burned a 27128 with the CRT files concatenated together. I also removed the first two header bytes from each CRT which appear to be an address header. I tried with $6000 first then $A000, and the other way around and nothing loads up when I power on, I’m assuming it will auto-boot? Anyone have advice on how to test if the cartridge is loaded into memory? Thanks p.s. I'm pretty sure the default jumpers on the card (blocks 3 & 5) line up with $6000 & $A000 EDIT: And I just realized in my rush to make this last night, I forgot to add the .1Uf capacitor, I'll solder that on and re-test! crt.zip

You can absolutely use 360k drives with the stock Ti controller, and as the stock controller is only capable of SD then that's what you'll get. 3rd party controllers were capable of more but I can't speak from experience as I've never owned one. There is a modification which allows you to read & write 80 track SD disks, but it's more of a novelty. Check this thread: p.s. getting ahead of ourselves here, but if you want to create floppies to test with, run TI99-PC 3.2.1 on a winxp machine with a 360k drive attached.

Can you expand a bit more on "problematic" ... I'm not sure if you mean problematic in terms of rarity as in finding controllers or technically as in what is compatible with what. Stating your specific questions will help us answer 🙂

Are you looking for only 5 1/4 floppy drives "original" to TI / PEB? e.g. PHP-1250 (MPI Model 51) IMHO Floppy Controllers that support DS/DD are quite rare and will require like drives.

p.s. I imported the panelized version (Vic16K-G_P.brd) of the VIC-20 16K ROM Cartridge into EasyEDA and ordered a batch of 5 PCB's to play with Thanks All for helping a VIC-20 Newb (me) with this!!

Agree, thank you for the link!!

@oracle_jedi That board is perfect! But the shipping costs 3x what the PCB does I'm going to spend some more time researching "open source" boards that might fit the bill because I can have 5 of those made & shipped (without components of course) by JLCPCB for less than $6 USD p.s. thanks for the tip on making custom labels, indeed very professional looking!

Thanks, I'll keep an eye out. I did some searching but I don't see any ready-made boards in stock. Would need shipping to US.

@Keatah I feel our gaming tastes are very similar because many of your comments resonate with me. Especially those about Defender and Pac-Man. Really glad you mentioned Snack Attack! Definitely a pac-man type game, but faster and felt more alive. The sort of game you can "get in the zone on" and start feeling it. IIRC the sound effects were really good for an Apple II game. Agree about the scene, in my neck of the woods there was also a plethora of Apple II software titles going around. Nostalgia is a powerful thing (probably not for everyone) but there's something very comforting in reviving and re-living those old brain paths still laid down like wax in our grey matter.

@carlsson thanks for that, when you say "get a switchable RAM expansion..." is there a PCB or schematic publicly available that shows the memory mapping configuration and switches to enable eproms at the various memory access locations? Sorry, technically I should research this more before asking and/or study the VIC20 Schematics to derive it myself but If it's been done already, well a schematic is worth a thousand thoughts EDIT: Ok a quick google revealed this: https://github.com/dikdom/VIC-20-RAM-ROM-Expansion. And appreciate any comments about other user experiences / preferences with VIC-20 RAM Expansion or Mapping Techniques

@carlsson TYSM for your expert reply, you've definitely saved me from spinning wheels with this cart. About modifying the game, I don't have any experience decompiling or reverse engineering cartridge game code so that route is beyond my knowledge at this point. So are you saying I should look for a cartridge that has two 8K ROMS in it? I found this list of ROMS, anyone know what cart might fit the bill? http://mhv.bplaced.net/cbmroms/cbmroms.php

Yes! Definitely one of my top 5 favorite games on Apple II back in the day. I've been going back and playing it on all three platforms (on real hardware.) Recently played it on an Atari 800XL for the first time, and unsurprisingly (due to obvious limitations with stock Apple II sound functionality) the sound effects on Atari are far superior!!

I'd like to modify (hack) VIC-20 Cartridge "The Count" into a "Sky Blazer" cart by replacing the ROM with an EEPROM burned with these 8k images: Sky Blazer (1983)(Broderbund)(NTSC)[6000][multipart].crt Sky Blazer (1983)(Broderbund)(NTSC)[A000][multipart].crt I've verified these images work in Vice emulation using "Add to generic cartridge..." 4/8/15KB image at $6000 and $A000 Cart w/ Original ROM Other side of PCB Understand that $A000 is the 8K cartridge space. Is some memory mapping required to access the other 8k image in $6000, or can I just burn the two sequentially into a 16k eeprom? Appreciate any VIC-20 guru comments!

Hahah, agree. I found this at a VCF swap meet. https://vcfed.org/events/
