    project update: I'm working on a few modifications and add-ons at the moment, as far as rare spare time allows. Progress is slow. But the project is not dead at all. A bit patience is required...

    Thanks for sharing your experience! Can't you just operate it out of an XP or Win 7 virtual machine? If not, why not format a 2nd partition and install some old Windows OS for that purpose and make your PC a dual boot machine?

    Sorry, I did not see your posting. Multi-cart currently out of stock and currently is being re-furbished a little bit before next batch. All extension-types are in stock. You need both: Multi-cart (=memory) and special adapter for MPU 2000. I'll do a new price calculation soon, but as always, I try to stay cheap. After all, it is a hobby project not a commercial thing, but of course, I have to pay for components and delivery, too. Multi-cart (incl. eprom) something around maybe US$ 35 ... 40. Extension something like US$ 15. Shipping to your country? Just look at DHL's website and use their price calculator. Used to be cheap until 2019. Thus spoke the raven: never more... Ordering: simply PM me on AA Paying: Paypal or bank transfer Best regards, Roland

    Hi Bill, well, me, I'm using a good old Willem Programmer (version 5) http://www.sivava.com/index.php?route=product/product&path=33&product_id=181 which used to be on ebay for years. Now this model seems to be sold out. It has a few drawbacks, like you need a real $2f8/$3f8 parallel port. Ok, retro-people usually have an old XP-laptop lying around. The loading coil of the onboard converter is too small to reach higher programming voltages. I lift it up with a laboratory power supply. The burner-software is not really ready. But it usually works. So this setup is ok for me, since I got my work-arounds and I burned countless eproms with that. Nowadays, you would look for an USB-capable burner of course. Maybe not the cheapest one (makes life easier). There are not many different models out there anymore. It should be capable of burning 27C-types, which is what we mostly need. I'd ask the seller, if that type is served (usually yes), if there's no data sheet available. For me a Chinese "version" would be sufficient. But I have no personal experience with the newer models. Maybe somebody else?

    project update: Today I shipped the final multi-carts of the latest batch. Concerning memory-carts, I'm sold out at the moment. I still have all extension-types on stock. I will make more multi-carts, after finishing a revision (almost there). Unfortunately there seems to be no cheap international shipping available by DHL anymore. Until end of last year I could deliver worldwide for EUR 6,20. Now, it's dependent on the destination. For example, same service to EU countries: EUR 13,99 (price increase 225.6 %) USA: EUR 19,89 (price increase 320.1 %) Better rates only are available for business customers. I've been asking several employees, but nobody could tell me how that really works. Obviously you'd have to do some standardized online preparations and provide a lot of data before bringing the parcels to some obscure place, that nobody knows. I think, DHL management simply loves adventure games! I wonder, what's their plan? Is it just to see how much they can squeeze out of the business? Do they have more goods to transport, than their capacity is able to? Are they trying to get back into control by choking the market? I wish them good luck with their new business model and am waiting for some competitor to see his chance and jump into the gap.

    Pots-values may be a little bit high. PONG: usually 1M-Pots used. 330k (lin.) probably are better for playing. But just try.

    project update: Sorry, there is a little break. I can't work on the project at the moment. But it will go on for sure. I have a "mountain" of components waiting to be assembled and soldered on my desk at home. Just currently can't. Things hopefully will switch back to normal in a couple of weeks.

    Sorry feldhamer, I did not notice your post. No, I haven't yet. I believe probably all the "classic" 70ies and 80ies cartridges have already been dumped and are available as .bin or .rom-files somewhere, which emulators are expecting to access anyway. I know of some console specific dumper-projects, of course. Personally I'd have some concern, to "attack" modern home-brew cartridges, with a device like this, which I do not want to do, since I'm thinking, everybody who puts a lot of time into such a project very well deserves the money for his/her cartridge. For emulation of those games, I'd suggest to contact the author, if he/she would also sell a rom-file, maybe with a registration number or so. I think, as long as a game still is actively sold and available by an author or a company, it should not be "pirated", because this prevents authors from making new cool games. That's why I do not do any dumper devices. Old, undumped cartridges I'd probably tap the pins of the chip and simply read with an eprom programmer.

    Supplement: springboard touching left side: 30 kOhms (0x1f) springboard touching right side: 285 kOhms (0xd5) I think, i'm gonna make an adapter for ATARI-type-paddles. ATARI paddles will probably be very sensitive due to the 1 MeqOhm pots. Commodore paddles will fit better (500 kOhms-pot). Or I'll just look for some kind of old cheap pong paddles.
  10. Rolo
    I just discovered, there is an application for paddles for the ARCADIA 2001 type consoles: It's the game CIRCUS, which indeed only is playable with paddles. Otherwise the springboard just jumps into positions left, middle, right and the clown most likely crashes and dies.

    Hey, I just saw this. I'm probably not doing enough reading. Concerning sales figures? Well, I'd guess the system is as good as dead (, at the moment). It really could use a couple of attractive homebrew games. Derek, great that you put time and effort into that console again. I sold maybe 25 INTERTON-adapters and 15 or so 1292-AVPS-adapters. Not much going on. Maybe one order every six weeks. Just a few people, who still have some childhood memories, from all over the planet. The different 1292-families do not make it easier to cover demand. Everybody wants his special format to be covered, of course. I focussed on the two families, which I considered to be the biggest. Yes sure, multi-cartridges are not what real collectors are fond of. They want original hardware, boxes and booklets. But multi-carts are great, to check out a system or to save storage space in the appartement. Rolo

    project update: Not really much spare time at the moment. But received new extension cartridge pcbs. Supplies refilled

    No more International Play Your Vectrex Day 2018 ? No more announcements? Well, I won't be able to participate anyway, but just wondering....
  14. Rolo
    Exactly. Obviously it broke and fell off easily? Well, it's not urgent. I might make a new one, but maybe not. I don't know. Just came to my mind.
  15. Rolo
    Can anybody do me a favor and measure the dimensions of the SCV-door, please. Mine is door-less and maybe I'll make some kind of cover for it. Maybe of thin sheet metal. Some photos would be great, too. What does the snap lock look like? Thanks! Rolo

    Not a complete new topic, but might still be helpful: Another SCART- cable for SUPER CASSETTE VISION The information seems to be somewhat scattered around the place, so here again. I just made a SCART-cable for my new SCV. This is how I made it. Maybe you need one, too. It's working.

    I think, the schematics of the service manual are not a hundred percent correct, concerning paddles. I did some editing, from what I saw inside my console. The changes are not confirmed!!! Maybe somebody can have a look, if I did right or if I'm introducing new mistakes:
  18. Rolo
    I made a little re-drawing, which shows the circuitry better than the original, I think. Hopefully no mistakes.
  19. Rolo
    Well, obviously "they" prepared the console for paddle controllers and analog input devices, which they finally never needed. According to the Signetics' 2637 datasheet the IC needs "external RC-networks" on its four analog input channels (pin 8/9 and pin10/11), which can't be read simultaneously by the way. The pairs have to be selected by a register flag of the chip. I did not find any application notes for the chip. Looking at pin 8 the network is made of R20 (180K), R19 (10k) and C5 (100n), which makes a time constant of 190kOhms * 100nF = 19 ms (52 Hz). Pin 9 the network consists of R17 (470k), R18 (10k) and C4 (47n) => 480kOhms * 47nF = 22.5 ms (44.3 Hz), which is the same, taking into account, which component values you can buy, and their tolerances (52/44 => 20 percent). Same for the other controller port (pin10/11). Plugging in the two paddles interrupts R8 and R20 (the two 180 kOhms-resistors) and replaces those by the paddle-pots. Operating the controller joystick-switches, bypasses the four large resistors (2x180k and 2x470k) and is pulling the four analog inputs to nearly VCC via R9 (1K) or nearly GND via R21 (1K), with the 10k-resistors and the caps still in the circuit. Hopefully this was not complete nonsense!

    project update: Delivered all ordered cartridges. Redesign of extension cartridge-pcbs for VECTREX, 1292-AVPS, Ordered new extension cartridge-pcbs for VECTREX, 1292-AVPS, Arcadia 2001

    Uuups , I'll have a look, what I can find, in my messy "documentation". I hope, I just did not solder it like that, out of the top of my head. . .. ... .... I found some handwritten sheets, which I barely understand myself. It definitely needs some extra explanation, how to read the plans. And probably a few photos. I can't just scan those plans. This documentation needs some extra time. I can't do this right now. But it might be something for a cold winter evening. Please allow some time ..... ------------------------------------------------------ Typed in with my Arcadia 2001 controllers. Ok, nobody believes this.

    @ND40: I wrote a PM to you. Please read your messages, if you're still interessted.
  23. Rolo
    I made some new cartridges. I'll PM you.
  24. Rolo
    Without having studied the firmware or having made measurements, I'd say yes, a classic keyboard scan.
  25. Rolo
    Yes, why not? 7 (3 + 4) lines for the keyboard/fire buttons (not really separate buttons) 4 lines for the direction (X,Y, GND via R21, VDC via R9)
