Re: IC Tester [was: Memory tester]

Does anyone have this test device (Fairy IC tester) that could figure out the schematic? Or take some pictures of the interface board - perhaps it is simply buffers for the test socket. Reading through the disk (Fairy... on TTL FTP) it looks like it tests TTL 54/74, CMOS 40/45, and HCMOS 74HC series - appears to be written in BASIC(? - been years since I last looked at APPLE II stuff) (RUN HELLO2, BRUN HMOS & this and that)...I can't find anything to do with RAM tests unfortunately... I wonder how many of us have Apple II's sitting on a shelf? I have three that still work...but this program might not be worth it - if someone else would like to look and confirm/deny my results just to be sure though that might be useful.

I googled around for it. There was one comment from a guy that had one that said most of the board was potted in black epoxy.

Memory tester

Can someone recommend a descent RAM tester for testing 4116's, 2101's, 2114's, etc. (Basically your typical video game/pinball rams) Matt

Well the last complete 9100 setup on e-bay had pods, probe, programmer option, interface modules (including Vector interface), manuals & software & even booted/worked. It sold for less than $500. This unit apparently doesn't boot if it is looking for a floppy disc? Kev >Bidding war! Lets see if we can get it up to $50US....who here doesn't have >a 9100 that wants one?

It's low on the input and output of A5 because that interface IC only fires up when you are no doing self test. When you are doing self test, it gets its clock from the socket, which gets them from U22. U22 gets enables when you flip that switch to 6809E. And the input clock source to U22 comes from a clock divider (U21) that is clocked by by U23. So..... put the CPU connector in the socket and look at U22. If the output is low is it enabled? Is the input low? If it is is the clock divider running? If U22 is enables and the input is toggling but the output is low the I would suspect that the 6809E you are using in the micro socket might have gone bad is is pulling those lines low. Lemme know what you find... -Adam >From: Eggwheatis(a)aol.com >To: ajcrm125(a)hotmail.com >Subject: Re: 6809 pod problems >Date: Tue, 15 Jul 2003 12:32:03 EDT > >Hi Adam, Ok well the latest is I've been checking the clocks...The E clock >is >held low at the processor...The self test socket seems to output the Q and >E >clock ok, but as soon as you plug the the CPU connector in the self test >socket it holds the E clock low.
