GroovyBee Posted January 25, 2016 Share Posted January 25, 2016 They look like wire wrapped versions of T-Cards to me. Are they on ebay? Quote Link to comment Share on other sites More sharing options...

+JasonlikesINTV Posted January 25, 2016 Author Share Posted January 25, 2016 (edited) A guy on Reddit posted them a few years ago, then reposted recently. The pics are in his Imgur album. Here's his original comment: "Long story short my step dads father worked as a developer at Milton Bradley and moved to Mattel shortly after. While digging through some of his stuff a couple years ago I found these development/prototype cartridges. I didn't give them much thought until recently and am now trying to seek some answers. I do not have the carts in hand as they are at my dads house. I asked him to take a couple pictures this morning and send them to me. I can always ask for more or more detailed images if need be."

+fdr4prez Posted January 25, 2016 Share Posted January 25, 2016 Looks like road kill. Someone drove over the cart and its innards are now popped out (pooped out?) Quote Link to comment Share on other sites More sharing options...

Utopia Posted January 27, 2016 Share Posted January 27, 2016 Perhaps forward the photos to Keith as he may be able to shed some light on these. Quote Link to comment Share on other sites More sharing options...

GroovyBee Posted January 28, 2016 Share Posted January 28, 2016 How do you plug those in? Like a normal cart. The wedge end of the cart has been cut off allowing the perf board to protrude. Depending on the length of those legs you might need to rest the leg end on a book or something. Quote Link to comment Share on other sites More sharing options...
+nurmix Posted January 29, 2016 Share Posted January 29, 2016 From Keith Robinson: These appear to simply be early hand-wired prototypes of T-cards. Early 8K T-cards held four 8-bit EPROMS holding the LSB (2 least significant bits) and MSB (8 most significant bits) of the 10-bit ROM code. There additionally were extra chips for latching and addressing. The chips seen here correspond to the same chips on a T-card. I’ll show it to a couple of people who worked in the hardware (Design & Development) department for their take, but I’m going to say they are early handmade T-cards.

+BBWW Posted January 29, 2016 Share Posted January 29, 2016 The man who had these cards did a game for the TI-99-4a called Zero Zap while with Milton Bradley. Looks a little like BLIX. I've sent the info that I have to Keith as well. I have a copy of the full definition photos and I forwarded them to Keith as well. While at Milton Bradley he worked on the Microvision Handheld as well and was working on Football for it when he left. 1 Quote Link to comment Share on other sites More sharing options...
+DZ-Jay Posted January 29, 2016 Share Posted January 29, 2016 Can they be plugged in and played, or are they now merely historical artefacts? Quote Link to comment Share on other sites More sharing options...
GroovyBee Posted January 29, 2016 Share Posted January 29, 2016 Can they be plugged in and played, or are they now merely historical artefacts? They should be playable. However, something could have come loose (or be broken) in that wire wrap loom. If they don't work you could dump the EPROMs and make a *.bin out of them.

While at Milton Bradley he worked on the Microvision Handheld as well and was working on Football for it when he left. According to this web site ( http://www.videogamehouse.net/zerozapgv.html), Zero Zap was programmed by Herb Schmitz and released 3Q/1979. MicroVision games were released from 1979 to 1982. Couldn't find any other programming credits for this programmer. The other interesting I found out at that site was that Milton Bradley was developing a game system based on a TI 16-bit processor. Milton Bradley lost the rights to the system to Texas Instruments who released the MB system as the TI-99/4. Quote Link to comment Share on other sites More sharing options...

+BBWW Posted January 29, 2016 Share Posted January 29, 2016 I could find no other credits for Herbert (Herb) Schmitz either. I did forward that name to Keith to see if any more light can be put on these objects. Andrew, who's grandfather was Herb will try to get them on his next visit. I do find the "Feet" to be long. I only have an Intellivision II out right now and those are about 1/2 inch off the table to the cart slot. These legs look taller than that. I'll have to measure the height of the Intellivision slot.

First Spear Posted February 1, 2016 Share Posted February 1, 2016 It would be great to get a hardware guy to accept and interview on the Intellivisionaries Podcast, get their understanding about why certain things were done, maybe even how. From Keith Robinson: These appear to simply be early hand-wired prototypes of T-cards. Early 8K T-cards held four 8-bit EPROMS holding the LSB (2 least significant bits) and MSB (8 most significant bits) of the 10-bit ROM code.

Ignorama Posted January 31, 2018 Share Posted January 31, 2018 Could the left one be a legit prototype? How could I actually check it without breaking the shell? And what could this be worth? 1 Quote Link to comment Share on other sites More sharing options...
m-crew Posted January 31, 2018 Share Posted January 31, 2018 Could the left one be a legit prototype? How could I actually check it without breaking the shell? And what could this be worth? I just noticed that that prototype matches well with your comforter... Quote Link to comment Share on other sites More sharing options...
