Interesting, I used mine and one from archive.org

Interesting, this one was short though it was called test.bin and did not work. Different checksum with the newer one Richard posted

Thanks Richard, that one worked! What was different?

It did happen to be called Test.bin instead of test.bin .... but no change. Just a blank screen instead of Linearity Pattern. Machine gets super quiet when it goes blank.

When I start the test cart and it is supposed to go to the Linearity Pattern, I just get a blank screen. I tried pressing buttons to go to the next test, and get nothing, its like the program just locked up or something. I am using the VecMulti and I press reset and get the menu, and the really odd thing is all the games and other software I run seem to work fine. I tried the test cart image I am using in Mame and it comes up fine. Any suggestions?

I hope no one bought a Microvision on ebay or wherever thinking they could get a replacement screen from this April fools joke of a thread!

Looks like the "8 bit guy" used your book to make a video for his channel: https://www.youtube.com/watch?v=1UzTf0Qo37A At least someone in the comments listed your book as a citation ?

I remember releasing software for the BeOS many moons ago, an adventure game called Hopkins: FBI.

The store/inventory. You said you were part of a group preserving it

They never did.

Texas Chainsaw. Had it since new.

Got a link to the sofa?

Moved and can not figure out which power adapter matches the Gamer Tek. Will anyone tell me the specs of the power adapter?

Is your group buying it?

I made 75K a year in 1997 as a software engineer in the south. Now I make 75K a year as a software engineer , but houses and cars are far more expensive. People are not as smart now for putting up with stagnant wages.

Thanks for that information. Do you know what did the average house and car cost in 1961, compared to now?

One reason I keep using a Mac is Virtual ][

Just started so it may be a simple answer, but something in that book has me confused. In the book the example puts the vertical blank first , then the vertical sync. This seems backwards to me. From the example on 8bitworkshop.com , the example called 5.

In just 3 days?

The growth of Mortgage debt, car loan debt as well as credit card debt have outpaced inflation, while salaries have been stagnant. Perhaps the high debt load and low interest rates explain why your friends have more stuff!

The top few lines just started appearing scrambled in the last few days. Should I buy a cap kit or is this something else possibly?

Have our salaries been in lock step with inflation?

I would not be so dismissive of Mr. Davis and his creation. There are not too many insane paranoid schizophrenics writing functioning compilers , languages, graphics libraries, etc. let alone an operating system that all of it runs within. Terry was extraordinarily intelligent. IMHO his work could even be an inspiration for those who suffer mental problems, especially ones less debilitating than the ones Terry soldiered through. His mental illness is something that he dealt with daily and yet he worked at a more advanced level than most sane engineers I have met. Working through his programming examples on TempleOs was a very enjoyable experience for me, and I totally got the retro computing feel while running on modern hardware idea he had.

I would just use TempleOS (templeos.org) , gives you a fun coding environment that runs on modern 64 bit hardware. Everything runs in ring-0 , so it feels very retro with regards to how much control you have.

Only about a month until April Fools day!
