Wow, I only had two letters in the name of the Teac drive swapped and Google figured it out. Nearly 10 years ago I was able to find some of the Teac drives, but never got around to getting this working. Now it might actually be easier to find a real RX33 drive! Though I'm sure it wouldn't be cheap.

DEC's drive is some variant of the TEAC FD55G. I have exper- imented and discovered that the following drives/jumperings work with the RQDX3: TEAC FD-55GFV-17-U Jumpers in: HG I (Roman numeral 1) U1 U2 DC FG DS0 (for first RX33) DS1 (for second RX33) Jumpers out: (all others) Install the terminator, RA1, on the last (or only) drive TEAC FD-55GFR-540-U Jumpers in: I (Roman numeral 1) U0 U1 DC2 FG D0 (for first RX33) D1 (for second RX33) Jumpers out: (all others) Install the terminator, RA1, on the last (or only) drive Toshiba FDD 6882E1J01 (or ND-08DE-G) Jumpers in: LD DC DE D1 (for first RX33) D2 (for second RX33) Jumpers out: (all others) Install the terminator jumper, TM, on the last (or only) drive I have purchased many of the TEAC 540 drives from JDR Micro- devices in California, (800) 538-5000. They have the follow- ing items of interest: [NOTE: This is *old* info (1988) and probably isn't valid any more] FD-55G High density drive - $129.95 FD-5Y 'Y' cable to power 2 drives from the BAnn box - $2.95 FD55-MHW Mounting hardware for two FD-55G drives - $2.95 FD55-FP Beige faceplate for FD-55G drive (black is std.) - $2.95 FD55-SPEC Specification for FD-55G drive - $5.00 FD55-MAINT Maintenance manual for FD-55G drives - $25.00 Therfore, you can get two RX33's for $265.80 with the Y cable and mounting hardware - a far cry from DEC's $795.00 each... You need an RQDX3 to run these drives, of course. You will also need to save the skid plate from your RX50 drive. If you order these drives elsewhere, please remember that the mounting hole threads are *metric*. Finding the right screws will be a lot harder than finding the drives! =========================================================================== ===== Note 93.77 Low-end disk devices - The Digital difference 77 of 136 EISNER::KENNEDY "Terry Kennedy" 15 lines 19-JUL-1991 01:40 -< Newer Teac model for RX33 substitute >- --------------------------------------------------------------------------- ----- A number of people have asked me for other RX33 substitutes, since the Teac models I gave earlier in this thread are no longer available. I did some experimenting and I have a new one for you: The Teac FD-55GFR-149-U can be used as an RX33 by installing jumpers on FG, DC, I, and D0 (for 1st drive) or D1 (for 2nd drive).
