100TPI floppy disk drives

AED (was PDP-11 graphics products)

I worked at AED from 84 - 86 and was the architect of the AED 1280, which was their last graphics terminal. The 767 is a modification of the AED 512 which used 64k instead of 16k DRAMs and 4x the frame buffer space. The original designers of the 512 did their own version called the Jupiter 7. It has a 6502 processor and an RS232 or 'AED' (parallel intf, the same as the AED 3100 floppy ctlr) parallel interface. I still have most of the docs/firmware for these. AED terminals were popular with chip designers. The Berkeley CAD tools suite supported them, as well as VTI.

IBM PC Network Adapter 6450213 for shipping?

by earl＠baugh.org

I've found (in the slowly shrinking pile I'm trying to distribute) an IBM PC Network Adapter identified by what I believe is the part number 6450213 I've got the original box (from 1985 looks like) and driver disks and manuals. Doesn't look like this has ever been used. 8 Bit card, with a coax connector (it includes the coax cable). Not sure exactly what kind of network it would connect to... but I definitely have no need for it. Before I toss it in the scrapper, figured I'd see if anybody was interested in it for the price of shipping... (it also has a diagnostics for IBM Personal Computer AT, Hardware Reference Library Diagnostics, and IBM PC XT compatibility test diskettes...) Earl

Not completely on-topic, but a recent acquisition by the school had a schematic in the so-called "user's manual" that dutifully showed all the interconnections to the black-box ASICs and the 2 or 3 transistors (and handful of passives).

Dave, Have you considered using the Tim Mann software (cw2dmk) and the Catweasel? That would pull up whatever information is on the disk and you could use it to diagnose what is wrong with the disk. It won't decode the CDOS file format but it will give you the sector headers and the raw sector data. If you send me a disk, I will return it with a raw disk Catweasel image >from cw2dmk. Best of luck with your project. Andrew Lynch

Nice work. I do notice that you've listed two MCUs, a PIC 18F252 and a PIC 18F2620. Presumably, the design takes one _or_ the other, not both. Also, it looks to me like those 0.1" (2.54mm) jumpers is a bit high - $0.25 each, min q. 10. Other killers are the $15 handling fee (presumably because the order value isn't up to their minimum value - $50?), the RL73K2BR33JTD resistor (1 required, min q. 10 @ ~$2), and various min quantity orders. What might make more fiscal sense, to me, at least, would be to order enough parts to build two, rather than one. More of the teeny parts would be used up for zero additional expense, plus the order might cross the min-order threshold and avoid the $15 service fee. Of course, if it were _my_ order, I'd find some MCUs or other parts to round up my own order, just because I'd rather have $15 worth of additional components than pay a $15 fee that gets me nothing substantial. Thanks for laying everything out in a very plain and clear fashion. It's a great starting point, especially for those who might have to order every single part to build a kit (I see large numbers of things I'd pull from my own stores). -ethan

Olivettie Programma 101

by wmaddox＠pacbell.net

There's what appears to be a very nice Olivetti Programma 101 up on eBay, with a little over a day to go and no bids. It's in the Netherlands. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=8801280590&sspagename=AD… The Programma 101 was a very advanced programmable calculator, introduced in 1965. Discrete transistors, delay-line memory, magnetic card I/O. I've exchanged a little bit of email with the seller. He says its been in storage for a long time, and a couple of rubber belts inside have turned gooey, but looks to be complete and in otherwise good shape. If you want a little bit of discrete-transistor goodness, I doubt you can find it in any smaller package than this (Ok, so a 9100A/B has both discrete transistors *and* core memory, but the Programma 101 was earlier.) I don't have any relation to the seller, I just decided that I wasn't going to bid on this, so I'd make sure the list saw the listing -- this is a very desirable machine and I figure someone, maybe one of the UK folks, would go for it. --Bill

VT100 flyback / geometry

by cc＠corti-net.de

Does anyone happen to know the exact part number of the flyback transformer in the DEC VT100 terminal? The VT100 in question has the 'DEC' type video board, not the 'Ball' type. Is there a matching HR-Diemen or equivalent part number? Oh, and questions concerning another VT100: What may cause a bad geometry of the picture on a VT100 (slight trapezoid and pincushion; Philips CRT)? The only adjustable magnets are the two sets of rings on the neck, one for the position and one for the focus (it's a magnetically focused CRT as most monitors are). Christian

choosing a 360k FDD

by dgriffi＠cs.csubak.edu

So, I'm faced with a bunch of 360k floppy drives. One of them I will put in my main desktop machine for replicating floppies for, say, my C64, Kaypro, etc. What should I look for when choosing such a drive? The best specimen I have right now was taken from a Morrow Micro-Decision. According to the tag, it's a "TEC FB-503". Can someone tell me something about this? By the way, I have an IBM-branded full-height Tandon that I will trade for the "ideal" half-height. -- David Griffith dgriffi at cs.csubak.edu

Its >> also easier to find. >> >> >At least as I can remember, the RQDx3 needs an internal distribution > panel. I'm searching for ONE single board. Understood. Most of the nonDEC FM/EDSI boards still require a distribution pannel as they were targeting DEC systems. At a minimum you need to make a hybrid cable to use them with one drive. How can you tell? Simple, if the board is said to do FM/EDSI and has only a 50pin connector a breakout board (distribution pannel) is required. Most do. I have several differnt examples of nonDEC MSCP controllers for floppy and hard disks and they all like the 50pin cable to breakout. There may be some that do not I don't have one. Actually there are several possible distribution or breakout boards. They primarily serve to translate the 50pin RQDX cable to the more typical cables used for floppy and FN/EDSI disks. One is the distribution pannel used in the BA23 and its only connectors and wires so easily duplicated. Its function is to take the 50pin cable from the RQDXn (or nonDEC MSCP) and route them to the 34pin connector for floppy and the 26/34 pin cables used for MFM. It is located in back of the drive bay of the BA23 and can be used outside of BA23. The second is the M9058 used in the BA123 and that is a dual width Qbus board that can support 1 floppy and 3 hard disks. It's Qbus but only takes power for running the local buffers and extended device select plus providing the interconnect point for the ready/writelock switch pannel. While it appears complex it's really trivial and is better described as a breakout board. If You get a M9058 it is not required to install it on the Qbus, only provide it with needed power if that is mechanically more suitable. The reason for that is while it's dual width it's thick due to the presence of many connectors. The M9058 is typically located outside the BA123 backplane cage nearest the disk bays for easy cable routing. There is a third board RQDXE that is for use mostly in BA23s for extending the RQDXn outside the case for additional drives. Its of limited utility as breakout/distribution. I know this from fitting two half height HD + RX33 in ba23 and also putting RQDX3 in BA11S with RX33 and 3 RD52s. Hope this helps. The only MSCP boards I've used that didn't require breakout were SCSI. Allison
