by Alexander Jacocks 18 Jan '23

All, Did anyone see a Hakko desoldering gun, in its case, at the last workshop, in the CDL? I am not sure what I did, but I can’t find it in my car. Thanks! - Alex

Is anyone planning to set up a PBX at VCFE in April? I'll be running a BBS on one of my big Tandy systems. Mike Loewen mloewen(a)cpumagic.scol.pa.us Old Technology http://q7.neurotica.com/Oldtech/

I need to make some space...
by William Sudbrink 17 Jan '23

17 Jan '23

I'm not getting rid of my whole collection or anything, but things are getting a little tight in terms of physical space and I have stuff that simply doesn’t keep my interest. I’d rather not do ebay so I’ll offer them here first. I will put up pictures if there is interest. None of this is “barn stored”. It has all been in my temperature controlled house since last century. 1. HP series 100 (the 150 and 150 touchscreen II) documentation. This could be described as the “grey wall” for the HP 150. All the basic books plus Wordstar, Spellstar, Multiplan, etc.etc. At least 20 “boxed books”. Many (I think all but have not checked yet) have original diskettes. HP-150 with built in printer, floppy and hard disks to come when I get back to it. 2. IBM PC original “boxed book” “DOS” part number 6024001 on spine. I would call the condition excellent. Two original 5.25 diskettes: DIAGNOSTICS Version 1.02 6081552. DOS Version 1.00 6172212 (I’m tempted to keep this because of the CP/M –vs- DOS controversy) 3. IBM PC original “boxed book” “DOS” part number 6024001 on spine with round sticker “1.10 with Graphics”. I would call the condition very good. One original 5.25 diskette: DOS Version 1.10 1502330 4. IBM PC original “boxed books” "UCSD p-System": Beginner’s guide, Assembler reference, Internal Architecture Guide, User’s guide. The “User’s guide” box contains five original 5.25 diskettes: STARTUP, SYSTEM 2, SYSTEM 4, EXTRAS and UTILITIES. 5. IBM PC original “boxed book” IBM FORTRAN-77 Reference for the UCSD p-System. Contains one original 5.25 diskette: UCSD p-System FORTRAN Version IV.0 6936510 6. IBM PC original “boxed book” IBM COBOL Compiler by Microsoft. Contains two original 5.25 diskettes: LIBRARY 6936566, COBOL 6172250 7. Various other original IBM PC “boxed books”. Document Retrieval Assistant, 3101 Emulation, Dow Jones Reporter, SNA 3270, etc. etc. Maybe a dozen. 8. The box and binder for “Guide to operations, Personal Computer XT”. Unfortunately, it does not contain this. Instead it contains “The CP/M and IBM Public Domain Library” by Dynacomp. This all seems to be later CP/M, running on the IBM PC or Kaypro. Just documentation and listings, no media. 9. IBM Graphics Development Toolkit “boxed book”. Three original 5.25 diskettes: VDI device drivers, Language Libraries, Supplemental Programs. 10. BASIC – Personal Computer – PCjr “boxed book”. Contains original ROM Cartridge “Cartridge BASIC” 1302285. (Maybe this should go with the PCjr I will be offering when I dig it out) 11. ERGO MOBY BRICK 486DX-33 computer. Missing original power supply. I cobbled together a supply last century some time and it worked then. Has not been powered on in at least 25 years. 12. Osbone Executive. Limited Edition, personalized plaque to “ANNETTE KING”. It ran last century. Has not been powered on in at least 25 years. More to come.

Repair Workshop 2023-01-14 & 15
by Herbert Johnson 17 Jan '23

17 Jan '23

> Anyone else want to chime in on what they worked on? Saturday, I assisted Dave Gesswein, in successful recovery of my Intel Multibus System 320 hard drive's contents. Those contents were a Xenix installation for that Intel 80826 based system. Those interested can contact me for details. The recovered drive image will be processed by a group of Multibus supporters. My thanks to David for his MFM recovery and replacement services, they are an outstanding contribution to vintage computing restoration. I chatted with a few of the other workshop participants, and obtained parts from a few of them as prearranged. Dan had some questions about restoring Macintosh floppy drives, and so I spent some time with Dan on those matters. David and I muscled the Xerox Star from the Warehouse to the CDL lab for his repairs. We looked briefly at Neil Cherry's OS-9 68K system, but David waited for Sunday when Neil would be available. Neil reported he wasn't able to get to his system then. Well, I'll encourage him to work on it in the future. It's a nice system. Regards, Herb Johnson -- Herbert R.

1/15 repair session, the OS-9 68K for Dave
by Neil Cherry 16 Jan '23

16 Jan '23

Ooops, forgot about this. Good news the system is in the lab. Bad news is it wasn't one of my main distractions. It wasn't totally ignored. I need to pull the disk drive to see if it's operational. I'll see what I can start tonight. Good news is that Dave was able to read some of the Gimix ST255 drive (similar format to the 68K OS-9 format). And the 68K has the same kind of drive. For those interested in the Gimix, I asked about Gimix OS9 boot disks and David Weins asked me about what disk controller it has. The OS-9 os is a lot like CP/M. You have to gen the disks and have all the correct device driver for it to work. Dave Gesswein checked the disk image he has from the Gimix and it's OS-9 Level II. So the Gimix can access up to 2M of RAM, I think. OS-9 for the 68K is more like Level II and there was no OS-9 Level I for the 68K. The rest of the folks are probably getting glassy eyed over this but for the 6809 the levels are how it handles memory and processes. It's a bit like UniFlex for the 6809, another scared Unix like OS for the 8 bit processor. -- Linux Home Automation Neil Cherry kd2zrq(a)linuxha.com http://www.linuxha.com/ Main site http://linuxha.blogspot.com/ My HA Blog Author of: Linux Smart Homes For Dummies KD2ZRQ

Settings for Jan (1/15 repair session)
by Neil Cherry 16 Jan '23

16 Jan '23

First, I had a great time with all the VCF folks on Sunday at CDL. I met new people and had fun getting distracted with this and that related to vintage computers. :-) I was working with Jan on her IBM PC/AT and getting the setting for the cards. Well my memory isn't so good but I did find a useful site that will help. http://dosdays.co.uk/topics/io_addresses_irq_dma.php If the network card can be set for IRQ 9 that's a good spot. PC/XTs could use IRQ 2 but that's handling the IRQs 8-15 and IRQ 9 is it's replacement on the AT. IRQ 3 is com port 2 and IRQ 4 is com 1. I got them backwards. The above web site has good references for the IO ports. This get muddled depending on the settings of the other cards. I seem to recall that many PC, XTs and ATs didn't have an LPT2 and I don't recall seeing a sound card in your machine. -- Linux Home Automation Neil Cherry kd2zrq(a)linuxha.com http://www.linuxha.com/ Main site http://linuxha.blogspot.com/ My HA Blog Author of: Linux Smart Homes For Dummies KD2ZRQ

Repair Workshop reminder 1/14 & 1/15, 2023
by Herbert Johnson 13 Jan '23

13 Jan '23

Weather looks good for me to drive up Saturday, not Sunday. David Gesswein kindly accepts my request to read an MFM drive I have. I have some parts to pick up from various people. I'll bring a simple 6809 kit to assemble with some of those parts. And I'll float around to see if I can help others with repairs. Regards Herb Johnson -- Herbert R.
