My IBM 1410 FPGA project now features a working 1401 mode as well, with the flip of a switch, exactly like the original IBM 1410. There are still a few real problems (e.g., Console I/O Input under program control doesn't seem to be working), a few minor issues involving console problems when doing control operations, and lots of changes I want to make to the PC console support program, which really should be done before tackling I/O devices. There are posts relating to the debugging of the 1401 side of things towards the end of the list that appears on page: https://www.computercollection.net/index.php/ibm-1410-fpga-implementation/ JRJ

Houston Instruments HiPlot Plotters - Pens?

by Gordon Henderson

I have a HiPlot plotter - it's DMP-29, but I'm fairly sure it takes the same pens as the DMP-2 which I also have but in a million pieces - but right now without pens. I have been promised some but it may be many weeks... I'm wondering if anyone has any old (or NOS?) pens for them? What I'm after is the dimensions with a view to 3D printing new pens - or at least pen holders so I can fit modern pens into. (There is no height restriction on the pen bodys) Can anyone help? (I'm in the UK if anyone has any physical pens available - please let me know) Thanks, Gordon

Looking for the MAD-1 drive unit

by brad＠techtimetraveller.com

I have 3 of the 4 pieces of Modular Advanced Design's MAD-1 and every now and again I like to reach out and see if anyone might have the last missing piece I need. The MAD-1 is sort of like the evil twin of the Mindset.. although nowhere near the graphics prowess. Unfortunately like the Mindset the disk drives are a separate unit and unlike the Mindset the MAD-1 can't operate without them because the enclosure also contains the PSU for the whole computer. The floppy drives are nothing special.. just SA-455 360k. Anyway, Sellam's msg about trades prompted me to reach out again. If you aren't familiar here is a link to a pic of one CHM has. https://www.computerhistory.org/collections/catalog/X1620.99A Many thanks!!

Printers, etc available for sale

by Marvin Johnston

Does anyone still use the older dot matrix printers? The husband of a friend of mine passed away and I am helping her dispose of his classic computer stuff. If there is interest in them, I can put together a list of what she has (and I can see) in the six storage lockers :). The printers I saw today used the wide perforated paper. My memory is non existent after about 1 hour :). My current plan is to attend VCFMW in September, and I can probably bring stuff with me. The ones I remember are the Diablo 630 (?), Juki, and a number of others of similar vintage. Yes, he had half a dozen or so Kaypro and Osbourne computers in the first 18" or so of the storage unit plus one IBM compatible that I could see along with maybe six B&W monitors. There are also a number of bankers boxes filled with 5 1/4" and 3.5" floppy disks and period books. Marvin

Re: Intel Developers' Insight CD-ROM collection archived anywhere?

by Kevin Bowling

Can someone upload the ISOs of what we do have to archive.org? I found http://intel-vintage-developer.eu5.org/ but I'd like to grab it without the free web host ads.

Re: SCAMP at 61 (IBM Scientific Computer And Modular Processor) was Re: SCAMP at 50 (IBM 5100)

by Tom Stepleton

I have to assume that the SCAMP used in the IBM 5100 Portable Computer and relatives must have been a great deal smaller than the earlier machine. As such, a logical and unambiguous way to refer to it is "SCAMP Shrimpy." I hope this is helpful, --Tom

Old Professional/350 software, any of this out there

by Chris Zach

Starting to go through my boxes of POS stuff. I know of course that 3.2 is out there (minus the Pro/Communications option which has a bad disk in the distro) however are these disks out there now? Pro/Venix 1.0 on floppies POS V2.0a on floppies POS version 1.5 (with test diskette, maintenance application, a thing called Pro/Pre labelled "Diskette system", system overview and instruction disks) POS V1.7 (I have that here somewhere) Pro/Basic Version 1.0 and 1.2 SPSS/X For Professional (this is a really interesting one, anyone heard of this?) If so let me know and I won't copy them. If not I'll go over to the mighty Deskpro/XE and start sucking the data off for archives.... Thanks! Chris (Hoping to find old drivers or scaffolding or something that will give me a hint into how DEC ported POS)

1-click exploits was Re: BEWARE: Phishing

by Todd Pisek

Be aware that clicking on a malicious url can result on malware or spyware being installed on your machine without any further action on your part. All browsers have vulnerabilities. The most famous of these was the older version of Pegasus by NSO back in the 2014-2016 timeframe. These so called 1-click exploits are well known to bad actors. It’s a continuous cat and mouse game between exploit writers and infosec. For the interested, look at this report regarding Apple and the “Trident” series of exploits from 2016. https://info.lookout.com/rs/051-ESQ-475/images/pegasus-exploits-technical-d… —-Todd P.S. Exploits have evolved considerably since Trident and now include 0-click exploits. See Google’s Project Zero for instance.
