Hello, Yes the tape should poition and the head seak track one. The 2150 has a puck that pinches when the slide locks the cartridge in place. Check to be sure that the puck is not soft with your finger. DO NOT APPLY ALCOHOL TO THE PUCK. The puck is driven by a belt from the drive motor. Hope this helps. Phil

AT&T 6300 in the Bay Area

by classiccmp＠vintage-computer.com

I've got a nice, boxed and working AT&T 6300 that has to go ASAP. I've had it on eBay (item 190454801269) but the shipping is/was prohibative ($110ish for 3 boxes) and it's been languishing on The VCGM for too long. I'm brokering this for someone in the NorCal area and if it's not gone very soon it's going back to the owner and subsequently, eventually, to the recycler. I'll pass any reasonable offers on to the owner for consideration. Local pickup is preferred. And no, "you're gonna throw it away anyway so just give it to me" is not a "reasonable" offer. :) -- Erik Klein www.vintage-computer.com www.vintage-computer.com/vcforum - The Vintage Computer Forums marketplace.vintage-computer.com - The Vintage Computer and Gaming Marketplace

That may be today's definition but if you check the literature of the 50's and 60's I am sure u will find drums (along with Williams Tubes, etc) categorized as random access devices. Even the first disk drive was the IBM RAMAC 350 - as in Random Access Memory! I think IBM invented the term Direct Access Storage in the 1960s to distinguish devices whose assess time was short but variable; that is, in between core (random) and tape (sequential). So the historical definition may have been . needs essentially the same time.

Almost free: various DEC, Wyse items, for pickup Rockville, MD, USA

by js＠cimmeri.com

Last call for items located in Rockville, MD, 20850. Already taken: CCS S-100 chassis; HP 712; Fluke 8520. Almost free: $2 (two) dollars per item, local pickup only at this time, no photos. Offer expires 11/7/10. 1. Digital BA23 floor pedestal enclosure, complete with front + rear covers. Very decent shape. No yellowing (painted). 2. Digital LA100 Letterprinter w/ ribbons. Tested working. Has age yellowing (barely perceptible) but no heavy yellowing (eg. from UV light). 3. Digital LA75 Plus Companion Printer (LA75S-A2) w/ parallel + MMJ. Professionally refurbished and assumed working (but untested). Clean and nice cosmetic shape. No yellowing. 4. Wyse 60 RS232C terminal with keyboard and spare analog board. Terminal unit is in excellent shape all around, as is spare analog board. Keyboard was taken apart and thoroughly cleaned -- it works but 3 of the keycaps broke when it slid off my desk. No yellowing on any of the components. My handle on ebay is MdntTrain if anyone wishes to verify my reputation. Email me if interested in any or all. I will select who the items go to. Thank you, John Singleton js at cimmeri.com

Oldest original working proper computer (stored program etc)

No, sorry the ORIGINAL Manchester Baby no longer exists. Fellow members of the Computer Conservation Society have built a replica, correct in almost every respect but it is only a few years old so does not qualify as oldest original working stored program computer. I still would like to make a list of the top ten not just the top one.

The Z3 has been destroyed, yes, and > rebuilt by Zuse in 1962. Thank you, this is just the information I wanted. Is the Z3 stored program? Turing complete? If it is, then it would be useful to know when the rebuilt version became operational, though I'm not actually sure the actual month my machine went live either. Assuming for now that Z3 is not stored program, than my list so far is: 1958, LGP-30 1958, Zuse Z22 Somewhere between 1954 and 1962, IBM 650 1962 ICT 1301 serial no 6 (SO FAR the earliest surviving machine with random access program and data storage. i.e. Core and called Immediate Access Store by ICT). Thanks again. I expect the chaps in the states will tell me of several more when I catch up with my e-mails.
