The 91**a has a 68000 cpu and the 91**ft has a 68030 cpu. The only difference is in the speed, all functions are the same but boot time and processing time are faster on the ft. To expand the RAM beyond 8mb on the ft we need an unserialised service disk (Macro maybe working on that :-) but it has been argued that no one is utilising 8mb yet :-). Your right that the 9100* probe is not the same as the 9010a probe but you can do all of the other tests without it. The 9100* can operate standalone and do the usual ram, rom, bus and I/O tests that the 9010 can but it also has some other benefits like being able to test 16bit data busses and also get sigs from interleaved roms with the step option. (Thank you Andy :-) The 9132a or 9132ft are for the 16 and 32bit processor but use a completely different way to test them. You actually replace the bios chip and there is an adapter for each cpu to control the uut which is done via an adapter that sits between the processor and the motherboard. The 9100* is more powerful even as a standalone fixture not running custom code compared to a 9010a or 9005a but if all you want to do is basic ram, rom, bus and I/O tests the 9010a or 9005a will do just fine. The 9100* video card is impossible to find unless someone has a beyond repair unit. Maybe one day someone will find a box full of them. I hope others will chime in and offer their experience as well.

Hello, all. I've been reading up, and am considering building out a 9100 setup to replace my 9010. Figured I'd reach out and ask for some advice and see if anyone was interested in working a trade.
Couple questions.
Can someone enumerate the differences between the 9100A and 9110FT? Looks like: Faster CPU (68030 vs 68000), different PCB layout, and can be expanded to 15(?)mb RAM (vs. 4mb) Anything else?
The 9100FT service manual mentions needing to change an EEPROM when upgrading the RAM. Has anyone done this? Is it also necessary for the 9100A?
Is the 9132 pod useful for arcade stuff? Looks like it's for 32-bit machines only — maybe you can use one to troubleshoot another 91xx machine?
From the manuals, it seems that all the calibration procedures require the probe. I was under the impression that the 91xx probe was identical to the 9010 probe, but I now see that this isn't the case. Can someone speak to how useful the mainframe would be without a probe?
Generally, without the harder to find video option, is it a significant upgrade from the 9010a / worth the money?
If anyone has 9100 stuff they'd be interested in trading, I have some parts I'd offer. Everything tested/working except as noted.
- 9132-024 ROM interface (can't test, fuse & cover missing) - 9132-028 & -032 ROM interfaces (can't test, complete) - 9010a w/serial, working except tape drive - 9010a w/o serial, working except tape drive & push-push buttons don't lock on. - 9010a probe - 2x NOS wrapped Braemar microcassettes - Like new 6809 pod w/manual - 6502 pod - 8080 pod - 6800 pod - 1802 pod - Z80 pod
& I think I'd be interested in locating:
- 9100A or FT - Video card - Probe - DIP clip modules - 1-2 Parallel IO cards _______________________________________________ Techtoolslist mailing list Techtoolslist@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/
