Literally just the CPUs. What should we have at the bare minimum? 4004, 8008, 8088, 8086, 6502, Z80, 6800, 6809...? What should we have if we have more space? 80x86, 680x0, Sparc, MIPS, Power, Alpha, ARM, Itanium...? Modern CPUs (to some degree) aren't out of the question, either, as we're hoping to show the progression of Moore's Law from the 4004 (2,300 transistors) to present day maybe, for example, a AMD Ryzen 9 3900X (at 9,890,000,000 transistors). Thoughts? I'm sure I'm forgetting plenty of important CPUs. ?????????? -Adam End of vcf-midatlantic Digest, Vol 21, Issue 9 **********************************************

ISA BIOS extension board?
by Richard Cini 08 Feb '20

08 Feb '20

All – I have an old 486 “shoe box”/industrial PC from 1994 that I want to toss a larger hard drive in to use with some Windows 3.11 experiments I’m doing. Unfortunately, it doesn’t have LBA BIOS extensions, so I’m capped at 540MB. I have one from WD, but it’s kind of creaky. So, I pulled out a 1.2G drive I had and installed OnTrack 9.57 which works fine. However, I feel kind of funny relying on the software wedge because you need to make custom boot diskettes, etc. So, I was looking for an ISA card with the LBA BIOS extensions. I know they made them years ago, but I don’t know exactly what they are called, so I’m not having much success in locating one. There may be other options like using an XT-IDE (if it does LBA; can’t tell) or maybe a different IDE card. Problem is that space is very limited (only 3 slots) and it has to be a low/short card to avoid interfering with the CPU fan. Any other suggestions/advice welcome. Right now I’m going to run with the 540MB drive I have, but I would like to find a better solution. Thanks! Rich -- Rich Cini http://www.classiccmp.org/cini http://www.classiccmp.org/altair32

The deadline is Friday, April 19. The rules and procedures are the same as last year. We rearranged the show layout last year, so that vendors will have copious space!

by Bill Degnan 06 Feb '20

06 Feb '20

Hi - Got a visitor to the shop today who was passing through and wanted help to copy files from an Apple ][ disk PRODOS format. I did not have one on hand so I asked him for his contact info to see if I could help him. Anyone have a system set up to archive a PRODOS Apple //e disk and copy to modern media/email to person? If so, contact me and I will forward to you his info. He will come to you but you should be in the general area of Downington. he just wants to see what's on the disk and recover the files if possible. I told him about VCF, he is going to try to make it this year if he can. Thanks Bill

Announcing the AppleII Classroom *ALL THREE DAYS* at VCF East 2020
by Adam Michlin 05 Feb '20

05 Feb '20

It is official! I can announce that we are going to have an Apple II classroom lab (9-12 Apple IIes) running classes *all three days* at VCF East 2020. Emphasis because this is the first time we are having classes on the Saturday and Sunday. This is something I have been dreaming of for years and working on with Tony Bogan since VCF East 2019. <http://vcfed.org/wp/festivals/vintage-computer-festival-east/vcf-east-apple…> Teachers will be: Stephen Edwards, Mouse Kelly, Dean Notarnicola, Javier Rivera, Tony Bogan and a lowly high school teacher who likes to teach students 6502 assembly which we wont name. ;) Retrobrite, Assembly, AppleBASIC, Joystick Repair, Modern Solutions for your II, the list goes on and on. Full class list at: http://vcfed.org/wp/festivals/vintage-computer-festival-east/vcf-east-apple… <http://vcfed.org/wp/festivals/vintage-computer-festival-east/vcf-east-apple…> Every day will also have an open lunch lab from 12:00-1:00 with Apple II games old and new. Maybe even brand new games if Michael Packard finishes his latest game in time. PS: The obvious question.. why Apple IIe? 1. It was my idea. 2. Tony is providing the IIes. More importantly, we expect to change platforms every year and hereby formally challenge the Commodore crew to start planning for the C64 classroom lab at VCF East 2021! PPS: Everyone should be proud of me for not making the obvious joke about the odds of getting 9-12 C64s up and running in the same room at the same time <duck and cover>

According to wikipedia, the Balans chair was invented in 1979. Mine's from 1984. Definitely the correct period. https://en.wikipedia.org/wiki/Kneeling_chair
