Hi, I am looking for a CH3s QH50, P/N 63F3825 for a 9221 ES/9000. A CH1s would also do. Anyone have an ES/9000 that is a brick because no processor console that can help me out? Regards, Kevin

I've not heard of the Wombat adapter - was that Sun related?

Comparing PDP-8 processor flipchip

by Bill Degnan

The recent Ebay auction for the original PDP-8 got my attention because one of the photos (the processor logic flipchip array) is a nice snapshot for comparison purposes with the system I am working on. https://vintagecomputer.net/digital/pdp-8/PDP-8_flip-chips_left.png (mine) https://vintagecomputer.net/temp/EBAYPDP-8ProcessorFlipchips.jpg Given my PDP-8 is close to working, I would assume that the Ebay PDP-8 would have a fighting chance, at least as far as the flip chip configuration goes. This is also a nice confirmation that I more or less have the flipchips in the right places. There are only a few slight differences. Bill

For Fred, especially: "Everything I know about floppy disks"

by Liam Proven

« Everything I know about floppy disks 2023-08-28 Floppy disk drives are curious things. We know them as the slots that ingest those small almost-square plastic "floppy disks" and we only really see them now in Computer Museums. But there's a lot going on in that humble square of plastic and I wanted to write down what I've learned so far. » https://thejpster.org.uk/blog/blog-2023-08-28/ -- Liam Proven - Profile: https://about.me/liamproven Email: lproven(a)cix.co.uk - Google Mail/Hangouts/Plus: lproven(a)gmail.com Twitter/Facebook/Flickr: lproven - Skype/LinkedIn: liamproven IoM: +44 7624 227612 ~ UK: +44 7939-087884 ČR (+ WhatsApp/Telegram/Signal): +420 702 829 053

Re: 8" DSDD to USB MSD?

Anders, for what practical purpose would you do that? It’s not like there’s so many 8 inch floppies around to make it feasible. You would have to have a LOT of intelligence in the Usb interface due to the different physical formats let alone the software formats. It would be difficult.

On Sun, 10 Sep 2023, Sellam Abraham via cctalk wrote: > We must teach Fred to long for the endless immensity of the written word > (in book form, focusing specifically on floppy disk drives). 45 years ago, I started writing about repairing Honda cars. Wasn't getting far until an acquaintance who fancied himself to be a writer got me to agree to do a book with him. He sold the idea to John Muir Publications (publisher of the Volkswagen Idiot book, different John Muir). I wrote it, my co-author edited, the publisher put their own editor on it, who butchered it. But, the publisher also brought in Peter Aschwanden, who is a GREAT automotive illustrator (see the VW idiot book). In 1979, I switched to TRS80, and did it with Electric Pencil, and then Scripsit. I had a DTC300 Hytype-I daisy wheel printer. I printed it 8.5" wide down the middle of 14 7/8 paper, giving lots of room for comments, etc. For the illustrator, I printed it on the left side of the wide paper, leaving a large area for doodles. The publisher's editor butchered it badly enough that my co-author switched to a pseudonym. With the publisher's accounting, never got enough in royalties to fuuly pay all of my expenses. https://www.amazon.com/How-Keep-Your-Honda-Alive/dp/0912528257 In the 1990s, I started writing about floppy disks, how FM/MFM worked, IBM/WD track and sector structure, directory structures, DOS Utilities, disk repair, etc. But, got bogged down with too much to do, such as closing my office, etc., . . . 20 years ago, I started writing an undergraduate textbook on Information Science. How searches and search engines work, and how to search better, how companies cheat the search engines (SEO), relevance ranking, trade-offs between recall and precision (cf. Buckland), the DIK[W[E]] (Data/Information/Knowledge/[Wisdom/[Enlightenment]]) pyramid, etc. I wanted to make a community college class out of it. But, certain administrators (who I failed to ever defenestrate) refused to consider understanding of information to be appropriate for community college (anything beyond their total lack of comprehension was "inappropriate") (Do YOU consider it "computer literate" to create a memo about a room change for a meeting in WordPerfect, print it with a color printer (for the logo and a ruling line), SCAN that printed memo, and send it out as an ATTACHMENT to an email with subject line of "FYI" and text body of "See the attachment"?) I haven't made progress on it lately. So, yes, I have always longed for the endless immensity of the written word, . . . -- Grumpy Ol' Fred cisin(a)xenosoft.com
