It appears to contain the complete sources. On the web, I've found the following: 1) http://www.retroarchive.org/cpm/cdrom/SIMTEL/CPMUG/CPMUG050.ARK This is an implementation for CP/M. The source for Tiny Pascal is in a non standard Pascal dialect. It claims to compile itself, however. Translates to p-code. There is no p-code interpreter, but there is a p-code to 8080 machine code translator. While this one does not mention Chung's and Yuen's version, it is obviously derived from it, as it uses some of the same p-code extensions, and compiles pretty much the same Pascal subset. 2) http://cq-pan.cqu.edu.au/david-jones/Projects/rcos/software/rcos.zip This is an implementation for MS-DOS. Only translates to p-code. Tiny Pascal is written in Pascal, and the documentation says that it was translated from the Northstar Basic sources. I would be interested to hear about anything you come up with or do regarding Tiny Pascal!

Quoting Eric: > In a question peripherally related to UCSD pascal, I recently > discovered "Tiny Pascal." KMMM Pascal had its genesis in Tiny Pascal. The early versions of KMMM Pascal were based on Tiny Pascal so I paid a royalty to Chung and Yuen. At some point all component parts of KMMM Pascal were coded in assembly language. KMMM Pascal was available for the Commodore PET a few years before the C64 was released. I got my hands on a C64 shortly after it was released and discovered that the ROMs in the C64 weren't much different than those in the PET. So it took me just a couple of weeks to get the C64 version of KMMM Pascal working. Willi

cctech digest, Vol 1 #476 - 3 msgs

by musicman＠satcom.whit.org

I had an accident involving 2 liters of coke and two dozen of my prize 5 1/4" floppies. I carefully slit the top (away from the access hole) and rinsed them in a sink of dishwater, then rinsed and let dry completely, then slit new disks, remove the new media disk and put the old (now cleaned) media into the new sleeve, and taped it with clear tape. Then immediately copied the disks to good new disks...They worked like a champ and I recovered everything....

From: Marion Bates <mbates(a)whoopis.com> To: cctalk(a)classiccmp.org Reply-To: cctech(a)classiccmp.org Bummer! Well, dunno if this will be helpful to you or not, but we had a zillion 3.5" floppies from 1984 (first Mac) and they got immersed in water during Hurricane Andrew in 1992...they didn't work at all, so figuring we had nothing to lose, I slit the labels, popped 'em apart, and removed the disk itself, wiped down both surfaces with Q-tips and rubbing alcohol. Then I took new floppies and disassembled them, tossed the blank media, and put the old disk inside the case...taped back together, and almost all of them worked well enough to recover the data. The real issue seemed to be that the two paper pads swelled and wrinkled, then dried, depositing lint on the disk surface and impeding spin. The disks themselves seemed to weather the water fine. (The Mac itself survived Andrew also -- I still have it. Only hurricane damage was a couple dead keyswitches on the keyboard, I replaced those and all's well -- 11 years later. :) If only the roof had been so durable...)

I need boot disks for the following: Morrow Micro Decision MD 1 Epson QX-10 several different Kaypro models I tried to make a boot disk for the Morrow using 22disk and the 'STDCPM22' file at 'www.retroarchive.org'. 22disk did not have a file format for the Morrow MD 1, so I used the format for the Morrow MD 2. (As far as I have been able to find out, the MD1 had full height floppy disk drives and the MD2 had half-height drives, but they were the same capacity). When I tried to use the floppy to boot the computer, it would spin for about 15 seconds, then the computer would reboot. I was making the boot disk on a computer which had a 360K floppy drive.

classiccmp.org operational costs?

All correct. > I think what I'm asking is, how much of "your" money do you put into it > per year in order to provide the mailing list, hosting for those of us who > have data on the classiccmp server(s) etc.? Time: I put in a lot, the moderators (to whom you can credit cctech still existing) put in a lot, and the web developer for the new classiccmp.org website has been putting in tons of work. The development website really looks awesome. Hopefully I can share the url with the public before too long :) But I think all of us consider it a labor of love and this doesn't count as a "cost". Hardware: Currently the Classiccmp.org server is a single 1U box sitting in our racks. Intel Celeron 2ghz, 1gb ram, 3ware/escalade raid 0/1 controller, and two PATA 160gb drives mirrored (160gb usable). FreeBSD, apache2, mysql, htdig, mailman, mod_watch, perl5, php4, phpmyadmin, and proftpd to name the major packages loaded. The main functions of the server are the mailing list, the classiccmp website, and all the classic computer related websites that I offer to host for free. I don't view this as a "cost" either, because whenever the hardware needs an upgrade I post it to the list and people donate (usually via paypal, sometimes via check) to cover the cost of the hardware upgrades. I think the last upgrade I put in a chunk of my own cash but I honestly don't recall for sure, that part is not something I feel the need to track in any case. Speaking of which... the time is rapidly approaching where something needs to be done about upgrading the box. The real problem is just disk space is getting quite tight. One could argue that all we need to do is replace the two drives with big ones (terabyte each maybe, or 1/2 terabyte each). That may be the route to go. But there's another possibility I was thinking too that sets off a cascade of upgrade requirements. It'd be nice if the OS was mirrored and on two totally separate drives from the data (which would need to be raid5). The whole reason for this is so that in the future we could easily add more space WITHOUT taking up a ton of my time to reinstall the OS too. If the OS was mirrored for protection and independent of the raid set for drives, we could just add more drives when needs dictate and it would be a trivial thing with little or no downtime. The problem is, the current 1U case won't hold more than 2 drives total. So going this route would mean replacing the case AND the raid controller (the two most expensive parts). Perhaps a 2U case that has six exposed hot swap drives. The current raid controller only supports 2 drives, and only raid 0 or raid 1. If I had my druthers I'd prefer off the shelf generic parts rather than a fully integrated (but proprietary) box like a dell. I like being able to use replacement parts in an emergency that I already have on hand. But, I didn't mean to broach this topic here, that's for discussion another day. Bandwidth: HERE is the spot where money actually leaves my pocket - sort of. The classiccmp.org server actually uses a pretty substantial amount of bandwidth for a single webserver/mailinglist machine (more than many of my commercial service webservers). Bitsavers accounts for a chunk, but so do some of the other sites on it (some sometimes more than bitsavers) like transputer, calcmuseum, rainbow, trs80, cpm, dunfield, tellason, acornia, swtpc.com, retroarchive.org, wang220, sol20, etc. Many of these sites are similar to bitsavers in that not only do they have html content, they also have substantial documentation sections of manuals, pdf's, disk images, etc. In addition to end-user bitsaver file downloads, all the other bitsavers repositories are mirrors from the one on classiccmp. I'm not complaining at all folks, just stating the usage. Here's a datapoint for you.... last night bitsavers.org hit 80mbps (80 megaBITS per second). That's unusual though. I would say classiccmp as a whole tends to sit between 5mbps and 12mbps on average. 10mbps of symetric bandwidth is not cheap! Do not confuse this with 10mbps of asymetric bandwidth like you get on a home cable or DSL connection for $50/month. As soon as you start talking symetric bandwidth (as an ISP/webhosting/colocation company I have to have symetric bandwidth), you are talking real money (easily a factor of 10 times more expensive). So if I already have lots of bandwidth here, how does classiccmp cost anything... well, sometimes it does and sometimes it doesn't. My bandwidth costs are not pure metered. I pay for a set amount. There's a fairly significant cushion above that that my upstream folks will ignore for short periods of time. Above that, and I get an extra bill. The overage bandwidth is more expensive than the "prepaid" bandwidth. As a result it's in my best interest to modify my prepaid bandwidth level very carefully. I raise the prepaid bandwidth as my access/colocation/webhosting business grows. This means that my bandwidth costs have a "stairstep" look on a graph. When I raise it, I raise it more than I currently need to cover near term growth and spikes. So for example... if I have just upgraded my bandwidth due to growth, I have gobs more than I need and classiccmp doesn't really cost me anything extra. As I grow and get closer to the "next step", yeah, it definitely costs money because it's using bandwidth I could be using elsewhere. But then the next step comes and I have more than I need and it's not a factor. So it's a VERY hard thing to quantify exactly what it costs. The "stairsteps" occur fairly frequently. Classiccmp often makes me go to the next stair before I would normally have to. Again, I'm not complaining :) > [is there just "a" classiccmp.org server, or is it all spread across > several machines?] See above.... one machine. Jay
