Herb solders up a compact Flash I/O board for an 8085
.. and here's where I worked on it Friday.

Antikythera Mechanism! But Not my first view of it!
Another view of this cut-wood replica. This hand constructed Antikathera Mechanism was purchased by Bob Roswell of the System Source Computer Museum in Maryland USA. It was constructed by David Goodchild (UK) who builds clocks and orreys.

More about the event is on my my VCF-East 2019 Web page.

Zenith ZT-1 video terminal in box

[vcf-e 2019] [vcf-e 2019]

Zenith (Heath) ZT-1 video terminal. Back panel has composite video out, parallel out for a printer, and phone-oline RJ-11 modem for dialup (probably 300 baud). 25 X 40 or 80 character display and some graphic chars. Manuals and AC wall-wart supply included. Powers up to a menu, you can set up dial-up phone numbers and features. Claims VT-52 escape code compatible. YOu'll need a crisp video monitor for 80 character work. So says the 1982 Popular Science review.

Unopened, untested for decades. In original box (did not confirm serial numbers) except I removed deteroriating black foam packing material. See if the newspaper is from Benton Harbor MI!

SD Systems S-100 boards - contact me to purchase.
$50 plus shipping through May 2019.

John Monahan has the manuals for these online on his SD Systems home page.. These are mostly IEEE-696 compatible, at least a subset of those signals. But the VF II and I/O8 I/O4 boards aren't complicated and will run on IMSAI's.

Apple IIe system, Duo drive, monitor, printer

[ii plus]

In 2018 I acquired this complete 1984 Apple IIe system, as shown with Duo drive, monitor, and printer. Tested the IIe and drives and monitor again in April, work OK. Apple II A2M2010 Green 12" Monitor. Printer powers and prints, but I did not run it from the Apple IIe. This IIe is not enhanced; it has the 80 column/64K card, a disk drive card, and a printer card. I have (not original) boxes for the computer, printer and monitor (for handling NOT for shipping). There's also additional software disks and documents. All sold tested and working but AS IS no returns.

Here's the 1984 Apple IIe, unenhanced. Inside is the system board with 1984 27th week date-stamp and boards as installed. Here's the Apple monochrome monitor, green screen in operation. Here's the Panasonic KX-P1091 dot-matrix printer Prints OK, parallel interface, does multi-pass for higher resolution text. Ribbons are likely available from Staples today.

Apple IIe, 1 drive, no monitor

We've verified these Apple IIe computers in April. They include one Apple II floppy drive and disk controller, they boot DOS 3.3. Some have repaired power supplies (AC capacitor replaced). All sold tested and working but AS IS no returns.

Apple II plus

[II plus]

I have a 1982 Apple II Plus, working, appears to be unmodified from original. Video looked good, I booted DOS 3.3 in April 2019 (drive and drive card not included). The case label serial number is 424,XXX. An Apple warranty lable dates from 1982. II Plus motherboard date-stamped 8271 and has many year 1982 chips. There's a non-Apple 64K card. The keyboard has grey keycaps with white letters. The power supply (gold color) is of course working. Sold tested and working but AS IS no returns.
