Title says it all... I've been looking for one of these for awhile. Picked one up off eBay awhile back but it was totally trashed (though I now have several spare batteries & accessories if I ever find a working one...) Anyone have one for trade/sale? Thanks, Josh

IBM 2.5" WD-280 80MB Drives: Free + Shipping

by trag＠io.com

I'm cleaning house a bit. I have four IBM Model: WD-280 2.5" hard drives. The interface is not IDE nor SCSI. I once managed to Google up a page with an extensive listing of 2.5" drives (laptop service company?) which indicated that the interface was something else, the name of which I no longer remember. Anyway, I have no use for these. If you do, email me, pay shipping and they're yours. If I do not hear from anyone in one week I will dispose of them. Two of them are still factory sealed. A third one's bag is opened but the drive passes a non-electrical inspection. The fourth one has an ominous rattle coming from inside as if the head arm is swinging around loose. If you do not want the fourth one, I am happy to ship only three. Other markings on the drive include: P/N 06G6449 FRU P/N 95F4708 MLC C99714 I hope someone has a use for these unusual drives.

Ben (?), I note that on: http://www.altair680kit.com/index.html or more specifically, http://www.altair680kit.com/manuals/Altair_680-VTL-2%20Manual-05-Beta_1-Sea… Grant Stockly refers to "VTL-2" from Gary Shannon and Frank McCoy. The manual says it requires 768 bytes to implement on a 6800 (which has, admittedly, a pretty flexible instruction set, including good stack operations). Not knowing anything more about your system or the language than what I've posted above, I still suggest it might be worth a look. -- - Mark 210-379-4635 ----------------------------------------------------------------------- Large Asteroids headed toward planets inhabited by beings that don't have technology adequate to stop them: Think of it as Evolution in Fast-Forward.

My return to Classic Cmp - San Diego, software archive, etc.

by tshoppa＠wmata.com

Hi Vern! Certainly Don was always happy and joyful to help out in any way he could with the contents of his archive and his ability to make odd-format floppies for any CP/M user. If you ever get to the archive, you'll find several dozen floppies (Compupro and VT180) that I sent his way. In the 1990's I was encouraging him to make disk images and make them publicly available. Tools at the time were teledisk etc. He was worried about copyright issues with a massively public on-the-net archive, he said. Tim.

Apple II keyboards

by us21090＠yahoo.com

All, I'm looking for a final accurate answer. When the Apple II's came out, the keyboard had a power-light that looked like a lit up key at the keyboard's lower left corner, below the shift key. Apple II+'s had a power-light that was (nearly) flush with the case. See these for comparison: http://www.vectronicsappleworld.com/ads/ads/appleii/howto2.jpg http://www.computercloset.org/apple2Plus.htm The question: Did Apple ever produce II's with this flush-power-light keyboard? I know the II and II+ lines were sold concurrently, so it doesn't surprise me if, for a time, the hardware was identical. All I've read (and which sounds definitive) the only initial difference was the ROMs. See the 1980 price list mid page two: http://www.barse.org/blog/archives/apple1980pricelist.pdf . In time, the II+'s motherboard's did go through changes Other, slightly related info It has an Apple II 16K model #: A2S0016. The motherboard is a Rev 4, which, if I understand it correctly, was used for both II and II+'s. The silkscreen on the MB near the "apple computer inc" text (above ROMs) says 1978. The manufacture date code (handprinted on MB corner near slot 0) is 7928-- 28th week (mid July) 1979. It has the AppleSoft/Auto-Start ROMs, but these were available as an upgrade. (The previous owner also added memory to 48K plus a language card). Oh yeah, the previous owner lost the lid!! All this is consistent with it being an Apple II. BUT one kicker is that the keyboard has a (nearly) flush power light that are used in II+'s. Thanks, Scott

If your architecture Turing-equivalent it doesn't matter what operations are missing. Tiny Basic, UCSD Pascal, Logo, Java, Scheme and lots of other languages have been implemented this way. Sure, this might be slower than a "native implementation," but you can always bootstrap a native compiler later if you have the time. Byte-code interpreters typically run faster than "regular" interpreters. If you can find it, I would recommend UCSD Pascal. It is a full-featured language (structs/records, etc.). I ran this on the Apple II in about the amount of memory you have.

OT? Heavy duty web hosting needed

by tosteve＠yahoo.com

Hello, My entire classic computer website is down for exceeding my monthly bandwidth allotment. I exceeded 60 Gigs in 2 weeks. Can anyone recommend a good host? I need 150+ Gig/month bandwidth. Thanks! Steven Stengel http://oldcomputers.net

Kennedy tape drive 9600

by silvercreekvalley＠yahoo.com

I'd like to try and get a Kennedy tape drive (9600) up and running and wondered if anyone had any advice or possible interface cards? The unit is complete and appears to be working, I have two 50 pin connectors on the back, and the ribbon cables to IDE connectors. This is the PERTEC interface I'm assuming? I'm ultimately wanting to connect this to a PDP 11, but initially it would be good to connect this some how to a regular PC. Are there any cards available to do this? I do have older PC's (this is vintage computing after all) ie with ISA slots which I'm guessing would be required. Anyway, any pointers/leads appreciated. Thanks Ian.
