Hummm !!! This is a good idea !!! I read some articles and people saying that, Z80 is "software" compatible with I8080, but I ever never see one case study. Can you drop a few words about this ? I have a few working board sets that I can "play" with... and I promise I'll try and post this to this group the results. I'm now working one SRAM replacement for this board... I think I'm on the right way...

Hello Guys... I'm thinking if is it possible to drive the I8080's Phase Clock 1 and 2 using a PNP transistor ? No, I'm not trying to re invent the wheel !!! I'm trying to put one Space Invaders in one FPGA IC (it's re inventing de SI), and once I'm doing this by piece, I mean, replacing board by board, I want to solve the MOS signal on ROM board. Any ideas on how drive this signal witout the 75365 ? Thank you !

Yes... Almost the same thing... I'm working on Taito Part II. I changed some emails with Mike... he is a very nice guy, but once I'm learning FPGA, I decide to start my own project.

WTT: Pair of intel 8216s - will trade 2114s or 2101s, etc.
by Bill Karkula 23 Apr '05

Hi, I'm repairing a Konami super cobra and one of the 8216s (quad bi-directional buffer) is bad. Anyone out there have one or two they would trade for 2114s or 2101s or 21C14s or some other ics they are looking for? Used ones are ok. Thank You and Best Regards, Bill _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist

Did you check the power levels with the Fluke pod in? Seems like I heard that it draws more power than the CPU. Also, maybe you have a weak component in the CPU circuit, since adding the pod changes trace lengths, power loading, etc. does it not? -----Original Message----- Okay, thanks for all the suggestions, now for an update ........... As Alex said above, my power supply was indeed sagging somewhat as I just upped the voltage and the Bus Test then passed okay. However ....... I still can't run the board with the Fluke attached using Run UUT - all I get Seeing that has reminded me to add that the CPU socket has recently been replaced. _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist

Fluke 9010A and Space Invaders
by Phil Morris 16 Apr '05

I have a Fluke 9010A with an 8080 pod - said combination works fine with every '3-layer' Taito Space Invaders boardset that I've used it with, but if I try it on *good, working* 'L-shaped' Taito boards I get the error: UUT Power Fail This has me puzzled - why should the Fluke work fine with one type of boardset, yet not the L-shaped set, even though said L-shaped sets work perfectly with an 8080 in the CPU socket?

Hi folks, These days, I was reading the Video Game Logic Handbook posted on the web by Spyes' website... Do you guys know where to find the missing volumes ? I'm wondering what kind of information is missing about old video games history...
