It turns out that both of the spare blocks have micro-cracks in them, in the same areas as the original block did. Rather than take the risk of having one of these overhauled and rebuilt, only to fail in a year or two, I decided to buy a known good block from the person doing the restoration. The price was reasonable and it should last a long time. Fortunately this one is also a 1930 engine, manufactured about a month after my original engine.

Today, I received a copy of a document titled, "Microprocessor Seminar 8008, 8080 : 3-daagse studiebijeenkomst Jaarbeurs Utrecht, 25, 26 en 27 maart 1975". This book came up in a world wide library search using the search term "Microsystems International". It sounded like it had lots of potential. Perhaps it had some information on the elusive MF8080 chip. As it turned out, it did not. It did however have some very in depth information on the 8008 processor, using the MIL Mod 8 computer as an example. Some portions are in English, but the majority of the document is in Dutch. It will need some translating, but I have posted it as is on my Mod 8 documentation page.
The seminar was 8008, 8080 seminar was held at the Jarbeurs Utrecht, which is a sort of technical fair center. It was given by M.P.J. Stevens and B.Veldstra of Technische Hogeschcol te Eindhoven (now the Eindhoven University of Technology).
While I am waiting for the results of my blocks, my friend Tom offered me a 1929 engine that he had lying around so I could build a spare. This engine was already been re-babbited and bored out, and it had the crank re-ground etc. All I need to do is assemble it and test. Since it is a 1929 engine, I would use this one temporarily until my other block is redone, as I would like to keep the car as close to original for the year it was made as possible. I have to order some parts to finish this off, mainly hardware and gaskets.
I made up some wall mounted units to display the Atari 2600 games I got from Sue Phillips (Chris Burger's sister) a few months back. These were part of my late friend's collection. I hope Chris would be proud. They still need some painting, but I think they look pretty good even without it. They are based on a design by Philippe Lafortune out of Montreal. Got some missing parts for my Model 15 Teletype, including some key caps. Believe it or not, there is this guy in California that has a shed full of parts for these things. I emailed him what I wanted (using the part #'s from the manuals) and he found what I was looking for and sent them to me for a modest price.
Below are some of the odds and ends I bought. For some reason the margin bell and the bell that can be rung remotely via a baudot command was missing as well. |
