LSSM is chasing this, was Re: General Data? Computer
I missed a lot of this because g-mail decided to bounce some e-mails. I would like to make a couple of observations:- 1. Many real accredited museums have a smaller percentage of their artifacts on display than private collectors. In the UK both TNMOC and the Science Museum Group have large quantities of hardware that is not displayed. The science museum usually catalogues it but it is not really helpful if you can't see it. 2. All the private collectors I know are very happy to show and demonstrate what they have. It might not be catalogued so well but generally they want to show it off Dave G4UGM (Now feeling guilty because what I have is neither catalogued or on display)

RE: Atari ST & MegaFile with Minix?
Whilst I am not an Atari "expert" I still own an STE and a have owned a Mega which died and a TT which I sold. In hardware terms there is very little difference between a Mega and an ST. As far as I know, given the same memory, all the games work on both and they really exercise the hardware. The first obvious difference is 3Mb of memory but that shouldn't cause problems. The second is that I would expect a Mega to have a blitter. Not all did but could the space occupied by the blitter be a problem. Lastly has the Mega had any modifications made? That could also cause issues.. .. and I assume TOS finds the drives on both machines Dave G4UGM > -Original Message- > From: cctech On Behalf Of r.stricklin via > cctech > Sent: 06 July 2021 05:37 > To: General Discussion: On-Topic Posts > Subject: Atari ST & MegaFile with Minix? > > I was playing with ST Minix (v1.1, based on PC Minix v1.3).

RE: Early Programming Books
Paul, What about Approximations for Digital Computers Cecil Hastings Jr., Jeanne T. Wayward, and James P. Wong Jr. Whilst its about a specific problem its not machine specific. It was originally published as papers in 1955 and as book later, but my copy retains its 1955 copyright.

RE: Early Programming Books
Paul, I assumed that was the case, but the inclusion of the Wilkes book confused me. I think there really is a spectrum of books, so say pre-1955 all books assumed the reader had little knowledge of programming. For example the MK1 guide I pointed you to is V2. Its rumoured that Turing wrote V1 and no one could understand it but I think it more likely the machine changed. I also looked at the IBM 701 manuals and they too have some generic info at the front. However I also wonder what the earliest books were like.

RE: Early Programming Books
Paul, What about machine specific manuals, so for example the Manchester MK1 programming manual, the second edition of which is archived here:- https://web.archive.org/web/20090526192456/http://www.computer50.org/kgill/m ark1/progman.html In fact I expect that first book refers specifically to EDSAC, so is in effect machine specific. There must have been similar manuals for other machines? I know there is a Ferranti Pegasus Programming manual, the copy I have is dated 1962 but as the last Pegasus was produced in 1959 there must have been earlier editions.

Its been a while but Attachate software generally only needed special hardware for stuff like 5250 twinax, 3270 co-ax, and various SDLC connections.
