I just bought a rig from Apricorn, via a IBM promotion for $69. Its a cheesy external box, adapters for the various style IBM hard drive carriers, and a PCMCIA IDE controller with a cable that plugs into either a IDE notebook drive or one of the carrier adapters. Includes special software to transfer contents of the internal drive to the new external (with license to do it 10 times). Normally $129, use the link through IBM and its $69. http://www.apricorn.com/ezgig_upgrade.html

The hardware works forever, but they sell this as a end user package, not a pro package for a repair shop. The software makes installing a new drive basically brainless by copying all the old software etc. over to the new drive. I bought the unit to install a new hard drive in my wife's 770, and actually use it myself as a laptop drive tester which doesn't use the licensed software at all.

I have five of them here. (probably some more buried deeper) These are Rodeo. One that takes 3.5" IDE, and four that take 2.5" IDE and have batteries. I've also used ones from Pacific Rim. Thank you. I have a policy of raising the price every time somebody expresses doubt of existence of stuff that I'm selling. After all, that proves that it must be RARE! Not too bad. There are easy ways and hard ways to do it. It's largely an issue of at what level it operates. (replacement Int13, v block mode device driver, etc.) -- Grumpy Ol' Fred cisin(a)xenosoft.com

It is fairly simple code, and the source code is in the Technical Reference manual. "uses a disk driver"?? It _IS_ the lowest level disk driver you've got. Int13 typically IS the ROM code that talks to the disk controller hardware. By intercepting the vector, it can be supplemented or replaced by code in RAM. This thread was NOT about BOOTING. If you want to BOOT using one of your Trantor/Adaptec T338/348/358 parallel port SCSI adapters, then you need to install a ROM in your computer that replaces and/or enhances INT13. Such a ROM is not commercially available as far as I know. To use ANY of the parallel port drives, whether SCSI or IDE, you need to either replace your ROMs with code that talks appropriately to that port rather than talking to the disk controller ports, OR boot the computer using a more "conventional" drive, and then run appropriate software that either runs as a block mode device driver, OR uses the network redirector (as CD-ROMs do with MSCDEX.EXE), OR hooks/replaces INT13. In short: Parallel port devices are not usually used to boot from. -- Grumpy Ol' Fred cisin(a)xenosoft.com

I won a eBay auction for a uVax. I'm only interested in the CPU and memory boards in it. I'm looking for someone that is willing to pick it up and send me the boards (I'll pay shipping). In return you can keep the other parts (which I have plenty of here). Here's the desc of the unit: This system is in a BA123 world box. It has been upgraded to a 4000-200 CPU and 16mb of memory. Included are VR19 19' monochrome display, 2-LK200 keyboard, mouse, 2-RD54 disks, 1-RF71 disk, CD drive and TK50 tape drive. The system consists of the following modules: M7626-aa, m7622, [M7169 and 2 m7168(GPX graphics set)], 2 m9047, m7546, m7552, m3106, m7555. A VT420 terminal is included. The system powers up and boots v5.5-2. Only one keyboard works. This system is completely functional with the exception of the second keyboard. Email if interested Kirk

On Sunday, March 27th, The Rhode Island Computer Museum effected the rescue of a large Wang VS-8460 system from Wall Street, New York City. Initiated by a referral from Lee Courtney and Dag Spicer at the Computer Museum History Centre in California, the system was made available through Garry Sprong, Edythe Childs and Steven Gorman of AIG Insurance. Scheduling and loading assistance were provided by Bob Bergen, Gabriel Duque and Jack Calandra, Manager H.R.I.S. Operations. Also appreciated was the assistance of Chester from building services. Dan Berman, Geoff Rochat, Peter Rochat, Ron Fraser and Merle Peirce formed the museum rescue team. The complete system was loaded with minimal effort and filled the rental truck. The Rhode Island-Gotham-Rhode Island turn was completed in only eleven hours. The system is in good running condition and has Wang VS operating System version 7.21.09 Qty Model Number Description 1 VS 8460 CP12 - 16MB Memory CPU 1 VS-SCU-PCT System Control Unit IOC 3 23V97W WangNet ControLr IOC 1 23V98-4 SMD Disk IOC 2 70V98E-4 Caching Disk IOC 1 23V95-2 Telex Tape IOC 4 23V67 Modular Serial IOC 1 16 Port 270-1004 Multi Line T.

This follows by two weeks another large donation of materilas from R. W. Evans in Cranston, RI. Included in this donation of assorted items, which also comprised a full truck load, were fully operating Wang VS-5, VS-6 and VS-15 systems plus assorted documentation, peripherals, software and micro-computer items. On the 30th, a long awaited item arrived by tuck freight from Pat Street in Orlando, Florida. We now have a fully operable, one owner 1981 Wangwriter with software and manuals.

Could you post who you have reservations from? (I hope I'm one!)

EPP provides a bidirectional data port, a data strobe, an address strobe, and a write strobe. It responds to a nWAIT/RDY signal, an interrupt, and three user input (to the PC) signals that you are at liberty to use however you like. The strobes are generated in hardware and rquire no software beyond the write to the appropriate address. The address strobe steers data to hardware that responds to address strobe, and the data strobe does likewise with what you define to be data, so you certainly have sufficient resources to effect an ide interface quite straightforwardly. Moreover, if you write a word to the data port, it steers the data in successive writes automatically with no software overhead. Performance, however, is another issue.

I'd be VERY interested in seeing that schematic, Tony! I've no doubt that it can be done, but I wonder how fast it will be.

Well, that must be the PPC34C60 datasheet. It has an "example" of what the SMSC folks think would be a typical application. You're quite right, by the way, that this chip appears to be intended to devise an ISA bus from the EPP, though it supports other printer port modes as well. Another interesting device in IP-core form appears at http://www.virtualipgroup.com/ds1284P.PDF. Both devices support DMA, which, IIRC, is not directly supported by the EPP, though it's not disabled from using it. What I'm curious about now is, where can one find a driver capable of emulating the ISA bus in a useful way under Windows, which is clearly what these devices were designed for, but I don't see it happening easily. SMSC (the semiconductor house portion of SMC, I do believe) has a few sample drivers and app notes on their web site, but I've got doubts.
