It's always fun to hear what tech toys (vintage computing or not) everyone got for the holidays, whatever you celebrate.
For me it was just buying a box of NOS floppies from Glitch back at Festivus :) and a pair of running shoes (not technical, but expensive!)
I just received a HP 82901M dual-floppy drive to go with my HP 87XM:

Haven't had a chance to try it, yet.
Oh yeah, I also just received one of David Gesswein's MFM hard drive emulators. Looking forward to trying it out on my old Tandy 6000HD, and attempting to image the hard drive in my most recent 6000HD. Mike Loewen mloewen@cpumagic.scol.pa.us Old Technology http://q7.neurotica.com/Oldtech/
Dave’s MFM Emulators work well, I remember when I exhibited one at VCF, while a bit confusing to use, no pretty GUI or anything like that, it does what it needs to do. I had tested it and duplicated an existing hard drive, and created several “blank” hard drives over my time with it. Unfortunately this year, I didn’t get anything vintage related, but I did get a WiFi controllable power strip that also monitors energy usage. So when I hook up my vintage systems, I know how much electricity I actually used. :-) On Mon, Dec 25, 2017 at 11:11 PM Mike Loewen via vcf-midatlantic < vcf-midatlantic@lists.vintagecomputerfederation.org> wrote:

MFM emulator, this means it can emulate hard drives like those inside the 3B1 & 3B2 or earlier drives? Were the early PC drives the same? BTW, found the missing Xebec interface card. I think this to allow those earlier drives to interface to SASI (early SCSI). I have no idea if it works.

Yes it works with 3B1 and 3B2. http://www.pdp8online.com/mfm/ http://www.pdp8online.com/mfm/status.shtml It works for systems using the ST-506 or ST-412 style interface (the 34 and 20 pin cables). The drives are pretty similar but the controllers are not. I currently have 34 different formats it can decode. I don't have support for RLL encoding, only MFM. May get to RLL sometime. The DREM unit support RLL emulation. ESDI drives look similar but it is an entirly different interface that I also don't support. I may be able to support the earlier 8" SA1000 drives with adapter but the drive I have (Quantum Q2040) doesn't have the electronics board and I don't have any computer with that interface to test with.
BTW, found the missing Xebec interface card. I think this to allow those earlier drives to interface to SASI (early SCSI). I have no idea if it works.
I have one of those in my TI professional. The seeker expansion board we put in it had SASI but SASI drives were very expensive. We got a good deal on the Xebec controller and a 10 Meg hard drive. I think it was from someone in the TI users group and the drive was used.
Unfortunately this year, I didn???t get anything vintage related.
Nothing for me either.
