David Craig had this to say about Lisa C: ... this C compiler was written by Green Hills. From what I recall about this from talking to a member of Apple's Lisa development team, this compiler was created under contract and Apple itself did not have any people who maintained this compiler. As such, this compiler had a very short life. I also believe that Apple's later Macintosh MPW C compiler was written in MPW Pascal and maintained by Apple. A later C compiler was written in C. Note also that Lisa C could only generate Macintosh object files, not Lisa object files (the Lisa's obj files were much more complex that the Mac's due to the Lisa's need to support a virtual memory segmented architecture). >From the Lisa C manual: "If you know of someone with a Beta version, then you can use it to generate Lisa code. The Lisa support was stripped out of the final version".

How I met your motherboard

A guy started a website called How I met your motherboard.. http://howimetyourmotherboard.com/ The NY Times interviews him on their podcast http://bits.blogs.nytimes.com/2010/05/12/tech-talk-podcast-ancient-pcs/?ref… The podcast is not as interesting as the site.

> How do you have MFM drives and nothing else of that vintage around? I'm not the OP, but by the late 80's my impression was that even the best of the MFM drives were pretty crappy in terms of reliability. In the early 90's in the minicomputer surplus streams good SMD and then ESDI drives and then SCSI became available (not necessarily free but affordable) and the best of these were built like tanks. In the mid-90's in the PC-clone surplus streams MFM drives were a dime a dozen. But most had never been in a 5150, they were from clones of the early AT era before IDE took over in that market. While putting a MFM hard drive into a 5150 was possible in any number of ways and certainly the power users did so, the vast majority of institutional 5150's (ones owned by businesses, hospitals, governments, schools) I saw were never taken beyond floppy drives. Every so often I'd see one with no floppies, just the cassette interface :-), those are the ones I took note of! Probably bought by the "power loser" instead of the "power user" crowd... the line could be incredibly thin sometimes! Tim.

wanted: Grid Compass 110x series equipment

by stuart＠zen.co.uk

Hi everyone, I'm looking to acquire a system and peripherals for the Grid Compass 1101. I did have a system several years ago and would keenly like to get hold of another one. Good price paid for someone willing to ship to the UK. Thanks! Stuart.

scsi-ide bridge LUNs

by chd＠chdickman.com

I have an ACARD AEC-7720U that I have been using in a VS4000/90 with good results. I am trying to compare different versions of NetBSD. I would like to split a 30GB IDE drive into 4 or so logical units. I don't know much about SCSI really, but I believe that it is possible to divide some drives into individually addressable logical drives, sort of like partitions, but at the hardware level. Can somebody enlighten me on SCSI LUNs, at least as far as they apply to dividing disks? Does SCSI define how to divide a disk, or is that proprietary to the drive? Since in my case the bridge is the "drive" would I need a specific utility from ACARD for this? -chuck

when you are trying to revive an IBM 5150, that : - you do not have a single AT powersupply in the house, just 20 ATX PS - do not have a single PC compatible keyboard, but 10 AT & 10 PS2 keyboards - at least 50% of your MFM drives have passed away in their sleep. - you don't remember which is the last DOS version that runs on a standard 5150 Time to grow up I guess.

Commodore C2N tape drive belt replacement?

by ethan.dicks＠gmail.com

Hi, All, I've been fiddling with PETs lately and have found to my dismay that my original c. 1978 C2N just doesn't push the tape along as fast as it should. I opened it up, cleaned some minor funk out of the innards, but the old drive belt is just a little sloppy and has a kink on it where it sat around the motor pulley for a number of years between uses. The symptom is that FF and REW speeds are not uniform, there's no real "grab" when pulling on the belt or manually spinning different pulleys, and there is visible slackness in the belt. Loads are spotty, and they mostly fail. The "secret" trick of holding down the ">" key when the tape is moving does show that the CPU sees flux transitions, but it fails to recognize what's on the tape(s) as valid data most of the time. I know the tapes are good, and a slipping belt explains all the observed symptoms. It's an easy enough part to replace, but does anyone know where to get a proper replacement from? It's a continuous rubber belt, with a square cross-section just under 1mm on a side, probably about 250mm- 300mm long, give or take a bit (I didn't measure it). It looks entirely ordinary in the context of 1970s cassette transports. Thanks,
