I remember circa 1977 CMU had a PDP-11 compiler for '68 with an extensive runtime component. I presume the sources are lost. Peter Hibbard was the guy responsible if I recall.

Yes, Peter was the author, and he also sponsored a corresponding ALGOL68 subset. My “history of Algol” web site has information here: https://www.softwarepreservation.org/projects/ALGOL/algol68impl/#ALGOL_68S In particular, there is a snapshot with binaries and some assembler files here: https://www.tuhs.org/Archive/Applications/Algol_68/ <https://www.tuhs.org/Archive/Applications/Algol_68/> and a later rewrite by C. H. Lindsey in the Amsterdam Compiler Kit here: https://github.com/davidgiven/ack/tree/default/lang/a68s https://www.clerew.man.ac.uk/#ALGOL%2068 See my web site cited above for additional information, papers, and documentation.

IBM 5110 IMFs

by Christian Corti

Does anyone here has an actual IMF file (Internal Machine Fix) for the IBM 5110? Not the file called "IMF" on the Customer Support Functions disk/tape, but a real fix. File type should be 23. I am trying to figure out how the patch mechanism works. The IMF is supposed to be loaded with the LOADER utility. Christian

I've scanned the press releases and adverts that come up on Google and I'm going to wager it was meant to be used with one or two terminals. Nowhere do they mention a display, and the adverts show a box sitting next to a terminal. Send me a copy of the ROM binary please? W

VAX 4000-200 in BA215 chassis. Can I install a KFQSA card and connect the cabinet disks to it?

by thomasdzubin＠gmail.com

I have a couple of VAX 4000-200 boxen running OpenVMS. I want to try out NetBSD on them but NetBSD does not support the SHAC DSSI controller on the KA660 CPU card. However NetBSD *DOES* support the KFQSA DSSI controller which I have a few of in my VAX 3800s. Can I install the KFQSA card in my 4000-200, disconnect the internal disks from the SHAC and connect the disks to the KFQSA thereby allowing NetBSD to run? Has anyone done anything like that? Happy 2024 everyone! Thomas Dzubin Calgary, Vancouver, or Saskatoon CANADA

Anyone have any IO Corp 8219HP docs or info

by Peter Ekstrom

Happy New Year everyone! I was wondering if anyone happens to have any documentation or information about the 8219HP adapter by IO Corporation? It is a protocol converter from Twinax to RS232 emulating an IBM 5219 printer. I am mostly looking for information about the option/rate switches on the back. I acquired one of these for cheap recently but haven't been able to find any information about it. Thanks!

Axil 220/245 PSU

by Alan Perry

Does anyone here have a running Axil 220 or 245 (Sun SPARCstation LX clone)? My 220 has a dead PSU and I am trying to get it working with a modern PC PSU. But I don’t know the pinout for the power connector. While the power connector is the same as used by Sun, the pinout and, aside from +5V and GND, the wire color scheme are different. I have identified 3 of the 6 wire colors and 7 of the 10 pins. The wire color scheme seemed to be a match for early sun4c but I just found something that suggests a couple wire colors are used differently. I have found that black is ground, red is +5V, and yellow is +12V. White, orange, and blue are TBD. A marking on the PSU board suggests white is -12V. Blue and orange seem to only used by a daughter board centered on a LM339 chip. But, as a software guy, I can’t tell what it does. Anyone here have any insight here that might help me? alan
