2708 help - Data sheet, programming specs, other...
by joemagiera 04 Jan '05

04 Jan '05

I own/use an EETools Top Max EPROM programmer. It's pretty versatile, however it does not do 2508's or 2708's. I contacted their support and they appear to be fairly customer responsive. They told me that they would update/modify their software to support any device that the hardware is physically able to do. I would like to take them up on their offer. However I am having difficulties meeting their requirements of supporting a currently unsupported chip type, which is: I submit 2 of each chip type requested I submit either documentation or web link, etc., of the data sheet and the programming specifications of the chip types requested. For those of you unfamiliar with the Top Max, they have went the route of making it a manufacturer priority based device. That means they don't just list 2732's, 2764's, etc.. They list the manufacturer first, and then the exact specific chip number/type from that manufacturer. What that also means on a new chip support request, is that the manufacturer of chips submitted must be the same as the documentation provided. Now for the help request: Can any of you identify the manufacturer of this particular 2708: http://www.joesarcade.com/joem/2708/ As I look at the pics again, on the front pic, could that be an "S" to the left of the 7812, which would stand for Signetics (now Phillips)? If I can figure out the manufacturer, I can pester them for the data sheet and programming specs. Even if they are long time non-supported, I've found if you bother a company enough, they will usually eventually hand you off to some old timer there that can dig up the info. But, if any of you might have those documents on hand, and can scan and post or email, that would be great. Thanks, Joe _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist

Data IO 29a questions
by Mike Coates 30 Dec '04

I just managed to get one of these, with the unipak 2 fitted. what is the difference between this and the 29b - can I upgrade it ? should I bother if you can ? I grabbed the 29a and unipak 2 pdf's, and I hacked the software in the first place to work on fast PC's, so I should have a copy of that somewhere! _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist

Kurz Kasch?
by joemagiera 13 Dec '04

13 Dec '04

I know I've seen/read Kurz Kasch referenced in many places related to testing PCBs. I never followed the posts because I never had one. While sorting through some stuff, I found I have something labeled Kurz Kasch. A pic of it can be seen here: http://www.joesarcade.com/joem/Kurz_Kasch.jpg Yes, that board is attached, and it appears that it came from the factory that way. Can anyone tell me exactly what, how, it's used? Any manuals on line anywhere? Is it very useful? I see some edge connectors on the bottom labeled Program 1 & Program 2. The unit does light up when plugged in.

Yes I've seen that on the schematics, alas both my 6800 PODS are different to the jumper switchable one :o( I tried doing a major hack on one of them to try and upgrade it to match the alternate 6800 (&6502) POD but I could never get it to pass self test :o( Dave Langley www.robotron-2084.co.uk _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist
