I sold my Lear Siegler ADM31 recently and the new owner (Ian) has found that one of the ROMs failed before he could archive it - or it was defective to start with. So my question to the list is - does anyone have the ROM codes (there are three of them) archived? I don't think Ian is a member of this list, otherwise I'm sure I would have spotted a post with a subject line like mine... Thanks!

Re: Apple 1

Not really, though that's part of it. The value of the Apple 1 has more to do with the Cult of Steve than anything else. Steve Jobs became the most celebrated CEO of his time. He was practically a rockstar. Personally, I think the admiration for Jobs turned into cringey idol worship, but the fact is millions of people around the world were impacted by the products Apple produced under his leadership, and he received the adoration. As I said previously, the Apple 1 is now an icon, a status symbol for the wealthy. The "Veblen Good" concept absolutely applies here. They have transcended our motley little community of vintage computer enthusiasts. They will continue to be held in high end collections for generations to come. Sellam

I guarantee most people who own an Apple 1 never use it, and it sits in a cabinet/shelf somewhere.

There’s dozens of similar machines from the same time period, vcreated by startups looking to be the next big thing, that just didn’t make it. Look at SWTPC, look at IMSAI, the COSMAC ELF. Apple made it to the big time, and they didn’t, so many more people with too much money would consider the Apple 1 to be a wise investment. > > I’d still prefer the IMSAI 8080 or SWTPC 6800 though. Collection values are so subjective that to me, that they make little sense. For example, is a Mac that belonged to Steve Jobs more valuable than the same model Mac that belonged to Harvey Schmidlap? Same machine--I doubt that any scientific test could affirm that Jobs was still alive in the former. But the difference to collectors may be a couple orders of magnitude. But then, I see little difference in value between an original painting and an expert copy. Yes, I know, I have no soul! --Chuck

IBM 1410 FPGA Status - 1401 Mode

by Jay Jaeger

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?

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
