1986 Wall Chart of Programmable Devices
by John Robertson 22 May '19

22 May '19

As was mentioned on Data I/O mail list, my wall chart on TTL's FTP site is a 16 page scan I got years ago...I did merge it into a single scan and I will delete for now the rather large TIFF (430mb) as it is silly big. If anyone has the original wall chart and can scan it in colour (green and white) as a single scan that would be great, for now removing the oversized TIFF will save folks a lot of space if they are downloading the Data I/O directory.

For the Fluke Z8000 Pod - making interface PCB for Z8002 CPU
by John Robertson 23 Apr '19

23 Apr '19

I have a Z8000 pod and am in the process of making a PCB for the Z8001 test socket on it so I can test Z8002 (Pole Position of course) logic. The PCB is to adapt the Z8002 CPU to the Z8001 test socket. I will likely be making two or three of these (minimum quantity) so if anyone is interested in one for their Z8000 pod please let me know - @ cost plus postage. I plan on having the PCBs run off either later this week or next.

by Joe Magiera 31 Mar '19

31 Mar '19

I have a couple instructional PACE VHS video tapes, TT-65 ThermoTweez and SX-70 Sodr-X-Tractor. Both tapes work fine and appear to be brand new. Hate to just throw them away. If anyone wants them, offering them for free, plus shipping. If interested, please contact me off-list (today please or they get tossed).

eBay BK Precision 560A
by Ian Eure 28 Mar '19

28 Mar '19

Saw this yesterday, looks like it’s sold as of today: https://www.ebay.com/itm/B-K-Precision-Programmable-IC-Tester-Model-PL-560A… Did someone here get it? The listing said it had the software to run it, which might also work for the 560 (non-A). That’s something I’d like to see saved, since there are no known copies of it. I messaged the seller to see if they’d be willing to share the software, but never got a reply. -- Ian _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com https://pairlist7.pair.net/mailman/listinfo/techtoolslist FTP site is: ftp://ttl.arcadetech.org/TTL/Test_Equipment Archive site: http://seven.pairlist.net/pipermail/techtoolslist/

3870 adapter pod for use with 6800 pod
by John Robertson 27 Mar '19

27 Mar '19

I can't believe it - I have had these files (Thanks to Shy!) since 2013 and only now realized I never put them up on TTL. This package from Shy (Navatek) has schematics (unknown format) pictures of the board layout and wiring, PALtoGAL 16V8 code and more... Look for it here if you want to make the adapter PCB: ftp://ttl.arcadetech.org/TTL/Test_Equipment/Fluke/9XXX%20Pods/3870_adapter_… I'd buy a board if anyone ever figures it out...

Used HP 547A to find a pin to trace short
by David Shoemaker 20 Mar '19

20 Mar '19

Have had this item for years and finally figured out what it is good for. Repair Log: Shadow Dancer Sega System 18 PCB Problem 1: Bad sprites in player and other screen objects Reseated Rom board: No change Checked all roms: Matched mame Probed around with logic probe and didn't see anything odd. Saw a clutch hitter on ebay for cheap so picked it up to do some comparisons with as I didn't have any System 18 in my stocks. Tried rom board on CH board. No sprite problems. Went back to original board and still had corruption. Started looking at the board closer, and found a nick in the traces. jumped 4 traces with Kynar wire. Problem solved Problem 2: No sound No sounds at all, but the CPU seemed to be running. Sounds fine if putting the rom board on the CH main. Verified the CPU to be good and the Sound PAL was also good. Started probing around the 74LS244 & 245 and found pin 5 on IC276 ('244) was looking bad. Grabbed my HP Logic comparator and clipped it on. Hit test and Pin 5 bad. As there are no schematics for the System 18 I did some continuity checking to try to figure out where that pin goes, found it goes to pin 2 on the sound PAL. And up to the interconnect for the Rom board. But due to a slipped probe I noticed something else. I was also getting continuity at GND (about 175ohm). And at the +5 rail (3 ohms). Bad 244, shorted internally so I clipped pin 5 and checked continuity again for GND and +5. Same thing. BUGGER. With the trace damage I had seen I thought there was probably a pin touching a trace somewhere. But after more than an hour with a tiny screwdriver and a magnifier I wasn't any better. Did some YouTube research on tracking down shorts. Really didn't like the idea of dropping a few amps down the +5 rail grounded through the pal pin to try and find something warm. I don't have a milliohm meter and they run a couple hundred $. I do have an ESR meter which is a small resistance meter but it wasn't high enough resolution to find it by probing around the board. Found a video on the HP 547A current tracer and using it to track down shorts: https://www.youtube.com/watch?v=Verow5aGL0w I just so happen to have one of these I bought off ebay years ago thinking it might be useful in tracking down vector board problems. But I have never taken it out of the box to date. Ran my logic pulsar output into the +5 rail with the ground of it tied to the sound pal pin 2. Then I was able to adjust the light on the 547A to just showing when touching that pin. Started tracing around the board and picked up the signal near the connector to the rom board. Ran along that area until I found a trace it was running up and followed it a couple inches then BOOM no more signal. There was a chip pin leg right the spot it vanished. Used my little screw driver to lift the pin and no more signal on the trace I was following and nothing at the pal pin 2. Put the rom board back on and sound fixed. Total cost of repair: < $.50 in kynar wire (not counting the Clutch Hitter PCB which I will keep as a ref board for the future) Total time spent: about 4 hours _______________________________________________ Techtoolslist mailing list Techtoolslist(a)flippers.com https://pairlist7.pair.net/mailman/listinfo/techtoolslist FTP site is: ftp://ttl.arcadetech.org/TTL/Test_Equipment Archive site: http://seven.pairlist.net/pipermail/techtoolslist/

Orion Instruments - Unilab 8620 Universal Development Laboratory
by John Robertson 21 Feb '19

21 Feb '19

Does anyone have the manual for this device? I have two pod kits for it - the 8088 and the 8031 - but was hoping that this thing actually did EPROM emulation as well. I suspect the emulation is only for the kits though. The only docs I have are for the 8088 and 8031 kits. Not sure if this thing is of any use these days, but it is nice to have the manual(s)... Thanks!
