VCF item request
by Tony Bogan 16 May '18

16 May '18

Was wondering if anyone has an Apple II SCSI card I could borrow for the show. The only spare I have is acting up, the other is being used. I don't care if it's an earlier revision or high speed as it's going in an Apple iie not a iigs. I could try to get another profile working but since I have the scsi drive ready to go this would be oh so much better :-) Let me know if any of you out there have a scsi card you're willing to lend for a couple days. Many thanks in advance! Tony Sent from my iPhone

ANNOUNCE: VCF East XIII 8085 Single Board Computer
by systems_glitch 12 May '18

12 May '18

Some of you may have noticed that I've been extra busy/slow to reply lately. It's not just because of taxes :) This is on my bench: http://i.imgur.com/TppyO2Mh.jpg We got together on the idea of a special edition vintage computer project for VCF East last year, but there wasn't enough time between when someone mentioned the idea and the event to actually get it done. This year, I've revised my 8085 SBC design into a larger, more full-featured board as seen above. Specs as follows: * 8085 CPU * 64K Static RAM * 32K ROM available in 4K pages * Autoboot/ROM switchout circuit * 8251A USART for console port * DS1233 EconoReset * Baud rates from 300 - 38400, baud clock independent of CPU clock * GlitchBus expansion header * Single 5V power supply The board is 8x5 inches, the GlitchBus expansion stacking area provides for a 4x5 inch board. Currently I've got the prototype version running GWMON, my ROM monitor, from Ferroelectric RAM in the ROM socket. The goal is to have a customized monitor and fully functional BASIC by VCF East. This is also the first board to commit to a GlitchBus pinout/layout -- several of us have been working together offline and through IRC to get it nailed down. Eventually, you'll be able to add a storage controller (CF, floppy, etc.) via GlitchBus and boot/run CP/M! The ROM can be switched out under software control, so the full 64K of RAM will be available to user programs. The board also supports FeRAM, so it's possible to have a core-like setup for main memory. If you use FeRAM or an EEPROM in the ROM socket, the board can update its own firmware. This revision is going to be released at VCF East XIII and is a special edition that will probably be limited to the show. We'll be doing an event-long workshop to build and test the SBC at InfoAge during VCF East, just like we did with the XT-IDE and Apple II prototyping workshop last year. If you choose to assemble your board at VCF East, you'll leave with a 100% tested and working 8085 SBC. I may bring a very few CRT terminals to make available to builders of the 8085 SBC. Evan got me a high-res PNG version of the VCFed logo, which I was able to work into a copper-and-silkscreen graphic for the PC board: http://i.imgur.com/H6iJnXIh.jpg I haven't nailed down a price for parts kits yet -- that will be forthcoming. Thanks, Jonathan

FS: Motorola MEK6800D2 6800 Trainer/Dev Kit TESTED/WORKING
by systems_glitch 12 May '18

12 May '18

link: https://www.ebay.com/itm/273207889695 This one looks like it was essentially built and never used. Nothing has been added to the prototype area, it looks like the EXORcisor bus connection was never plugged in to a socket, and there was no additional RAM in U18/U19 sockets. I cleaned it up, removed some areas of excessive rosin flux, and brought the board up on a 5V bench supply. It draws around 1A with address/data info on the displays. Ran through the sample program in the manual, which worked fine. I added two Fairchild branded 6810 SRAMs to bring it up to a total of 512 whole bytes of memory :) Didn't test the cassette interface, I no longer have a cassette recorder kicking around. If you're interested and will be at VCF East, let me know -- I'll take substantially less if I don't have to pay eBay/PayPal fees and ship. Thanks, Jonathan
