I've still got mine (around here somewhere). Loved the undocumented feature in the early kits - missing pullups on either the adx or data lines. I can't recall which now but it fuddeled me for a while. Never did understand why they had so much memory. Dick, N7XKC ----- Original Message -----

No, but I DID!? My very first home computer?? ;-) I started my career at National Semi.? They sold off a little development kit at the company store... A National calculator case (keyboard and 7segment LED display), about half a dozen logic chips, wire-wrap sockets and tools... A whooping 256bytes of program memory IIRC.? Writing in assembly, hand assembling, punching in hex on the keyboard and reading the hex output on the LEDs. A W9TO style keyer and a reel-to-reel tape(didn't have a cassette) storage system were the two big projects I was able to..? but it was great fun. 73, Gary WB6OGD On 7/28/2018 11:11 AM, Richard L.

And what about the "portable" Commodore 64 with the color screen? I was lucky enough to pick up two of them cheap back when and used one as a packet station for years. If I remember correctly it even had a built in floppy drive.

First "computer" I ever owned was a Commodore 64( 64k of RAM not megs) Wrote programs in basic on a 5 1/2" floppy disk for it. I'd hate to tell you what I paid for that system back then.

Re: allpcb, pcbway, etc 100mm x 100mm
I've done arrays of the same design with ALLPCB with no problems in the past.
My backup plan was just to run a few traces between between the different designs. I never really understood why they care what's inside the purchased area if they don't have to do any cutting, scoring, or routing. John? W1JDS |

Re: Some KayPro 2s >>>> Osborne 1

Paul,
The PDP-8f 24K of real core. Runs great never forgets. I also have 16K of core for LSI-11. Required a hex wide backplane. I started with 2708s, never cheap pain to program. Then again the first memory used was in the state machine (not a cpu) and the part was the 1101 they were 16$ (1973$) each slower than anything 1.5uS and only 256bits. Imagine in 1976 a backplane with 48K of 2102 (1kx1) 384 of them total on 6 boards and could they throw heat! Cost for them was around 1200$ in 1976 dollars. Memory was costly. Same for the early floppy drives the SA400 was $499 in late 76, a weeks pay! It was 1980 when the first SA506 (5MB!) 5.25" hard drive hit $499 and a S100 controller was another $499. Write your own CP/M 2 BIOS for it. By late 1980 I was pushing Z80s to 6mhz, had 256k of Eprom as a read only disk, 512K as a ram disk, hard disk and two sizes of floppy (8 and 5.25) the backplane had a single 64k card early that year and 256K with a MMU. Ran CP/M V2.2 FB. Whats FB? Rewrote a bit of the system to have a second task as a background job. I don't mean a printer buffer or some such, that was done by a 8085 on the bus. Up till then I t was bleeding edge, I got tired of the cuts. ;) However I didn't adopt PC hardware till the mid 90s. too slow and clunky, the PDP-11/23 and RT-11 was far faster till it became a slave to the MicroVAX. Those were the days. Then Arduino and Rpi happened, wooha were off and running again. Allison |
Re: Some KayPro 2s >>>> Osborne 1
Ah limited memory. Back in the late 70s I worked on a traffic signal controller based on a Cosmac 1802 (see Allison's post). The board had 128 bytes of RAM and four sockets for 2716 EPROMs. However, when we started on the project, 2716s cost $50 each so management said we could only use one on each board. After a few months the price dropped to $25 each so we were allowed to use two 2716s on each board. After a few more months, the price dropped to $5 per 2716 so we could go hog wild.

Also I have a DG Nova with real core memory and a front panel full of toggle switches and incandescent bulbs in the basement. It did work when I acquired it over 30 years ago but I have no idea what state it is in now. 73 de Paul (VA6PW) On 28/07/2018 1:18 PM, Jack Purdum via Groups.Io wrote:
