Is anyone interested in a Teletype ASR32 with paper and paper tape? Unknown working condition but in decent physical condition. Comes with some rolls of printout paper and paper tape. Most likely pick-up only in NYC. I'll explain why if you're interested and you e-mail me. Asking price is $100 (might be negotiable). Please contact me off-list for details. P.S. Another ASR33 sold on eBay for $730(!) -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

The problem with that is that it forces us to front hundreds of dollars, with no indication that we'll ever get it back. I already have boards sitting around from several projects, representing hundreds of dollars of investment on my part, that may never "sell" (even at cost). It is a lot better for us to have some idea of the demand, so we can mitigate how much "over-investment" we want to do. Though you are right, that if we found someone who would pick up the overhead cost of a board order ($200 each time), we would be way ahead. (Anyone know of a shop that can do a double-sided 16" board with solder mask and without a steep setup charge?) The other major ticket item for this project is the front plate. Anyone know where we can get those done inexpensively? Vince

I'd say that's wrong. Considering that the VAX8650 microcode engine runs at 68 MHz and manages about 7 times the 11/780, you're optimistic. The 8650 have a very large microcode word, actually have three (or was it four?) microcode engines running in parallell, and some very advanced cacheing and pipelining to speed it up to get even that far.

FlashManager 2000

> So... My search comes right back here. Does anyone happen to > have a copy of Flash Manager? Sorry for the multiple replies, but there are: >From http://www.smartm.com/product/m_tech.cfm a reference to: ftp://cust-ftp.smartm.com/Public/memcard.inf and From: http://www.magicram.com/FAQFlash.htm Q. Why won't my Linear Flash card work under Windows 2000? A. Linear Flash Cards do not come with drivers, it has always been the OS vendor's responsibility to include support for these devices. Unlike previous versions of Windows, the Flash drivers traditionally included on Windows distributions are not included with Windows 2000. The following information explains a work around to get Windows 2000 to recognize and use Linear Flash Cards. Be certain Windows 2000 has been upgraded with at least Service Pack 1 and the host hardware supports PC Cards. OEM installed Windows 2000 should not exhibit problems, but systems upgraded from older Windows versions may need confirmation that their hardware is compatible. Please note that MagicRAM provides this work around as a customer service and does not guarantee that will work with every system configuration. 1. During the Windows 2000 hardware setup process choose Display a list of known drivers... instead of Search for a suitable driver... 2. Select the category Memory technology driver 3. Select the M-Systems DiskOnChip2000 driver from listed manufacturer M-Systems Flash Disk Pioneers 4. Click Yes on the Update Driver Warning message, continue and click Finish to complete the setup process, click No from the restart Windows message 5. Access the Device Manager and highlight M-Systems DiskOnChip2000 from the category Memory technology driver (it has the conflict symbol) 6. Access the M-Systems DiskOnChip2000 and click Update Driver from the Driver tab 7. Choose Display a list of known drivers... instead of Search for a suitable driver... when the options appear 8. You should now have more default driver options, select the Centennial PCMCIA Memory Card driver from listed manufacturer Centennial Technologies, Inc. (other drivers may work, but the Centennial driver was used successfully in testing) 9. Click Yes on the Update Driver Warning message, continue and click Finish to complete the setup process, click Ok from the properties window then Yes >from the restart Windows message 10. When Windows restarts, you should see a new drive letter and icon from "My Computer" or Windows Explorer

Unibus SCSI (was: Any own an 11/725...?)

Certainly. Several actually. CMD made the CMD 720/722, which was both disk and tape. Very good controller. I have one. Viking made a controller, and I believe Emulex also made one. There were probably one or two other manufacturers as well.

Wondering which OS to use (PDP-8/A)

Speaking of integer arithmetic capability: the 8/A systems where you wanted better numeric crunch were expected to be fitted with the FPP8A, which can do both integer and FP stuff, and does it much better. (One of the options I'd like to find to play with, but haven't...)

Also, the PDP 8/A Minicomputer Handbook > 1976/77 has a lengthy section [pp9-56 .. 9-65] on the KE8-E (Extended > Arithmetic Element : EAE).

As I said, some 8/A systems were fitted with 8/E CPUs. It's actually almost on the verge of terminology confusion. I should probably have written explicitly that it's the KK8A that cannot have an EAE, while the KK8E can. However, there are no "field specials". The KK8A simply cannot have an EAE.

I might have those still around (hate to throw things). Let me check...
