Hi Ian,
The active ftp site is ftp://ttl.arcadetech.org/TTL/Test_Equipment , it is up for me. It is messy, and I hope whoever volunteered to tidy up the Fluke section will get in touch with me again.
Yep... It was timing out trying to connect eariler, but seems to be working now.
Hmm, a TLC.EXE file is tucked away here:
ftp://ttl.arcadetech.org/TTL/Test_Equipment/Fluke/9100%20Series/9100_TLC_Program_For_IBM_PC/
Thanks for that info, I will hunt my piles of discs, and old backups to see what appears. I also have a number of hard drives from my 6 x 9100As that I have never attempted to archive, so I think that is a project for the near future, who knows what is on them cause I don't!
What I was hoping was one of the other documents would go into detail on the modifications made to the motherboard that upgraded it to 1.44 floppies - you have to have version 5.0 of the ROM installed too.
Has anyone seen a 9100A with high density FDDs that operate in high density mode? I’ve seen UniSite programmers which had high density drives installed, but jumpered into DD mode so they’d work with the older controller on the mainboard.
Looking at the schematics, it seems like the A and FT use nearly identical chipsets, and I see a DENS line wired up on the A, which would control or indicate the floppy density... So maybe it’s simply a matter of installing the 5.0 ROMs, 6.1 system, and a high density floppy drive. If you have Revision G motherboard then I expect you have the 1.44 upgrade done. Look for a bunch of jumpers on the underside.
If you want to update your MB to the G level allowing 1.44 Sony (?) floppies (& you need RV5.0 EPROM) then here are what I think are all the mods: 1) Cut traces @ W5, W6 and W7 2) Jumper W5 (connected to U27-P3) to U72-P9 (unused 7417 gate). 3) Jumper U72-P8 to W7 that connects to J14-P1 4) Jumper other side of W7 (ground) to W6 (side connected to J14-P4) 5) Jumper U27-P1 to U72-P5 (unused 7417 gate) 6) Jumper U72-P6 to J14-P16 (currently N/C) 7) Jumper W6 (connected to CHNG2 - J13-P1) to W5 (connected to J14-P2 - /SPARE) 8) for RV5.0 EPROM check that W2 is cut Photos: ftp://ttl.arcadetech.org/TTL/Test_Equipment/Fluke/9100%20Series/Photos/ I think that is all of them. I need to draw up the revised schematics, but no time! Will do that over the next day or two.. John :-#)#
Probably easiest to start by swapping the disk from a FT into an A, setting the disk type with the service disk, and see what happens.
