The PDP-6 and KA10 (basically a re-implementation of the PDP-6 architecture) both had cheapo versions where addresses 0-15 were in main memory, but also had an option for real registers, e.g. in the PDP-6: "The Type 162 Fast Memory Module contains 16 words with a 0.4 usecond cycle." The KA10 has a similar "fast memory option". Noel

DIBOL manual

by jnc＠mercury.lcs.mit.edu

I recently picked up a copy of "CTS-300 - DIBOL Language Reference Manual" (because when I went to do a CHWiki page for the language: http://gunkies.org/wiki/DIBOL I could find almost nothing about it online); does anyone have enough of a use for this that I should put it in the high-priority scan list?

DIBOL manual

by jnc＠mercury.lcs.mit.edu

> From: Chuck Guzis > One could argue that it's just as similar to FORTRAN (cf. computed GOTO > and logical IF statements). It probably worth pointing out that I never used COBOL, and have little knowledge of it. So when one reads "it is vaguely reminiscent of COBOL, as it has a 'Data Division' and a 'Procedure Division'", I must have copied that all from some source I found, because I don't know what the 'Data Division' and a 'Procedure Division' are (although I can guess from the names). > Where it differs mainly from FORTRAN of the times is a facility for > record layout I seem to recall that COBOL was the first language with support for structures? If DIBOL has support for them too, which would be another similarity between the two. Noel

Fwd: IBM MST extender cards

by h.j.stegeman＠hccnet.nl

Hi Al, On the surface 3V & 1.2V is printed. This is a MST-4 card extender. MST-1 & MST-2 are different. I was also interested, but the seller was not willing to ship them to Europe :-( Regards Henk

Restoring dull BOT markers?

by dseagrav＠lunar-tokyo.net

What?s the best way to restore a dull BOT marker so I can get a good dump of a tape? I don?t need a long-term fix since tapes themselves are in exceedingly bad condition and are unlikely to survive more than one read.

Kennett Classic Opens This Friday

by billdegnan＠gmail.com

Hi - I was not going to write about this here until I was pretty sure we were on track, but it looks like we are go to open our new vintage computer gallery and hobby shop this Friday. If you're local to the Philadelphia/Baltimore area, look us up and better yet, pop in for a visit. Our first feature exhibit will be a Commodore History, but we also have a lot from the 1950's through the 70's on display to tell some of the lesser-known tales before the microcomputer era. The idea here is to bring vintage computing to the local community via something that they can identify with (i.e. Commodore) but also have historical depth for those of us who have a passion for the history of computing. For more details our new URL is. https://www.kennettclassic.com/ Thanks Bill vintagecomputer.net kennettclassic.com

qubex qa2000 disk tester

by marvin＠west.net

Is anyone here familiar with this disk tester? I'm actually looking for the operators manual or even better/more unlikely a service manual. I found this while digging through some of the "stuff" I've accumulated over the past 40 years or so. Marvin

SEL mainframe

by jwsmail＠jwsss.com

I think this is the guy who has the warehouse full of crap in Texas that was going to be scrapped, but now has its own facebook group. If you find and join the group, there are photos of it there. https://www.facebook.com/groups/433516373950693/ Vintage Computer Warehouse Liquidation (Houston) thanks Jim
