Attic Finds – Part 1

Friday, November 14th, 2014

OK, so I’ve been digging through old boxes in the attic in search of things that, of course, I never did find. But what I did find was:

Yes, it’s a full source code listing of the Star Trek game I wrote on punch cards, in FORTRAN IV, for an IBM Selectric HARD COPY terminal, connected to an IBM 360 mainframe in 1976-7 while at college.

PCC 77 Brochure

Wednesday, October 7th, 2009

Not many people probably remember that a large personal computer show/expo was held in Atlantic City way back in the late 70s. The show was the brainchild of John Dilks, a great guy who also co-owned and operated one of the earliest independent computers stores in the South Jersey shore area (The Computer Ark). If I remember correctly the PCC shows ran for two or three years total before the expense of running them in A.C. made them impractical.

I still remember writing BASIC demos for John to run on his S-100 computer at a local air show to drum up interest in PCC.

Working through some old boxes I bumped into the brochure for what I believe was the first PCC in 1977:

Ahhh, Retro-Goodness

Adventure on the BoGUS Board

For some reason seeing this screen on a 20-something year old Z80 board now booting CP/M 2.2 from a CompactFlash card just makes my day.

You are standing at the end of a road before a small brick building. Around you is a forest. A small stream flows out of the building and down a gully.

Welcome to the new Adventure! (25 years later.)

Vintage Computers: The BoGUS Board System

Thursday, April 24th, 2008

More vintage computer photos. This time it’s a Z80 processor based CP/M system that started life as another unfinished Franklin project. Bob Grieb was designing the hardware and I was developing the software for what would have been a portable CP/M machine. The cool thing was that we were so totally under the radar and had essentially complete control over all aspects of the design. We had a working hardware prototype at Franklin but the bulk of the software was written after we’d left.

A vendor at Trenton Computer Festival had purchased a large amount of Franklin stock but had no idea what some of it was. Bob discovered the bare CP/M PC boards, populated several and coded low level disk formatting routines while I wrote the boot firmware, CP/M BIOS, ZCPR and assorted utilities. The end result is actually a slick little CP/M machine that includes two floppy disk drives and a sizable RAM disk made from extra RAM banks.

I think I christened it the BoGUS board, as far as I can remember it stood for Bob Grieb’s Unusual System or something like that. I’m sure it’s in the source code somewhere.
