Hi. I realize it's been a while, but I just came across your post, and was wondering if you still have the logic trainer? Thanks.

Joseph, MO I've got 10,000+ 3.5" DSDD disks in boxes of 500 - Many as you want are yours for the cost of shipping (from Ottawa). Only catch is they have no write protect tabs (from the days when I used to ship on diskette)... I made up a little cheater to slip in under the disk corner - not the best for daily R/W use, but works very well for making permanent/backup copies of things. Also have a Victory autoloading drive if anyone is interested. (load/accept/reject under serial port control - processess 100 disks at a time).

Prerelease Mac Portable?

by cb＠mythtech.net

I noticed this on ebay tonight: <http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=4610&item=510057941 2> Seller thinks it may be a prerelease model because the FCC sticker says it isn't approved and can't be sold. Possibly they are correct, maybe it was a review model sent out before they hit the stores. I'd love to have it, opening bid of $9.99, but I'm sure it will go above my price range before it closes (and now that I've pointed it out here, that's almost a sure event). -chris <http://www.mythtech.net>

With regard to being able to FORMAT > a drive with an RQDXn controller, normally special XXDP programs > from DEC are REQUIRED! The RQDX1 and RQDX2 do tricks at startup to try to figure out what kind of drive they have connected (things like selecting unusual head numbers, seeking to high-numbered tracks) and if the results aren't what they expect, they won't recognise the drive. You can use many non-DEC 10MB drives with an RQDX1, given a suitable (early) version of the ROMs, but other sizes are tricky (and a drive that works with one version won't necessarily work with another). All the relevant drive parameters are fixed in the RQDX1/2 firmware. Things are much easier with the RQDX3, as it stores the drive parameters on the drive, so if you can once format it, it works. The table of values for approved drives is in the formatter program. In the later versions of the RQDX3 firmware, there is the capability to accept a new table entry from the formatter, and later versions of the XXDP formatter (ZRQCG0 and later) allow you to feed it values. If you do that, you also have to tell the formatter NOT to read the defect list (because there isn't one on a non-DEC drive, and when it tries to read it near the end of the 15-30 minute format operation, it will fall over). Working out the right values, however, is non-trivial. I've done it twice. The first time, in about 1990, it took days to work out what some of the entries meant. Now I just use drives it knows about already. You can also format a drive on an RQDX3 on a Vaxstation with VS2000 diagnostics. I don't know if that lets you bypass the UIT (Unit Identifier Table) as well, but I expect so. -- Pete Peter Turnbull Network Manager University of York

Macs: Billions and Billions sold.

That really annoys >> me, both from a donatig and a collecting perspective. > >The problem is that they now have to pay to get rid of anything that >doesn't work or is simply not saleable. Blame it on the environment :) That wasn't the case for the one near me (pay to dump garbage... in NJ? BAH! We love toxic waste, we like to build sports stadiums on it). The one that had been near me told me they wouldn't take them, because they got sick of people expecting support, or wanting to return them when Windows crashed. Since they had a strick "All Sales As Is, All Sales Final" policy, they were simply tired of pointing that out to people. So they stopped selling CPUs to avoid the headaches. -chris <http://www.mythtech.net>

Amiga external SCSI question

Is the Amiga A2091 external interface the same pinout as the old Apple 25-pin connector? I have the pinout for the A2091, but not for the Apple. Doc

RX50

by geoffr＠zipcon.net

Do you just need floppies formatted for RX50? what machine do you need them for? if it's for a Rainbow, then CPM and MSDOS will format them for you.
